Pinguino Eagle

Benoit Espinola designed an eagle version of the simplified 2550.

It will be available soon for download.

JAL with Pinguino

I discovered JAL and tried to make it usable with Pinguino bootloader. It's done !!
How to do this ?

Upgrade your pinguino with bootloader 2.12
Create your program and compile it with JAL ( i use piklab to do this ),
Convert your program with our jal2pinguino converter: ./jal2pinguino.py jalprog.hex pingprog.hex
Upload your program with VascoBoot.py

Add the option -loader18 8224 -no-fuse to the JAL command line.

links:
pinguino bootloader 2.12
JAL
JALLIB and JALLIB group
jal2pinguino converter written with python
vascoboot uploader written with python

The next Pinguino version will both support Arduino langage and JAL.

Thanks to Vasile, Sébastien Lelong and Albert Faber from the jallib group.

Pinguino bootloader version 2.12

A new version of the bootloader is available. Some bugs were removed ( particulary the start delay wich was a little short for windows computer ) and the bootloader is now compatible with JAL with our hex file converter ( see the next post ).

download it here

Virtual Pinguino


Walter from madrid works on a virtual pinguino model with ISIS on windows.
The bootloader works and Pinguino IDE can recognize the module as a real board. There is only a problem of speed when trying to download the code.
We will try to fix this.

Good idea and good job.......

Pinguino on 18F2455/18F4455

Finally, i tested Pinguino on 18F2455 and 4455. These chips offer the same functions but less memory capacity.
Everything is OK with bootloader V2, but i programmed the chips with 18F4550 checked. If i check 18F4455 on my programer software, nothing works !!
I use a home made JDM programer and IC-PROG with wine.
Maybe it will be useful for other users.........

FreeJALduino works !!

Vasi made FreeJALduino, a 18F2550 board exactly like an arduino ( see this post ).
I am happy to know that the first test works with a modified version of Pinguino.
I plan to integrate a FreeJALduino directive in the next version of pinguino.
Congratulations for this nice job Vasi.

Tiny 4550 on a proto-board

This is the last design of tiny pinguino 4550 on a proto-board.

It was drawn with Inkscape:



You must cut the tracks marked with a red point.
I used this home made tool to do this:



Now you can sold components and wires. The 18F4550 must be mounted on a suport.

This version offers the same functionalities as the PCB version.


The booloader V2 must be used with this design.

Last upgrade 29/09/2009: Cutting points were modified, thanks to André.

18F4550 schematic




Pinguino 18F4550 is now defined. This is a tiny version USB powered. The run switch disappeared and 29 I/O are available. 8 analogic inputs.
Linux and windows version will be soon available and the KICAD PCB is in test.

23/08/2009:
Schematic upgraded. The last was buggy, led on pin 6 must be connected to Vcc because RA4 is an open collector output. Kicad board is OK. Thanks to walter for info.

Pinguino with 18F4550

This is my first test of Pinguino with a 18F4550.


What are the differences with the 18F2550 version:
- 30 digital input/output, 13 input can be used as analogic input
- 470 resistors suppressed on the outputs,
- Run switch was suppressed, run is automatic after 5 seconds,
- Run can be manually controlled with a switch,
Processor will be defined in the IDE by a radio button or #define directive in the code.

The new bootloader will be compatible with the 18F2550 board version 1.
The development environment will be compatible with all software already written.

This modifications will be integrated in the beta 6 version. This version should be available april 30th. Other improvements in this version are:
- full support of UTF8 in the source, comments can be redacted in many langage.
- corrected some bugs in comments ( keywords are not accepted in comments for beta 5 ).
- case sensitive help in the editor.

Processing library for Pinguino

Last week, Stéphane Cousot wrote a basic library for communicating between Processing and Pinguino. This the first release but it was tested and is fully functional. Stéphane made a package with a processing sketch and the Pinguino program associated. You can download this package on Stéphane website.
This library is the result of our work with Douglas Edric Stanley. The goal is to build a USB interface wich can be driven by many different software ( Processing, Python, Pure data, java ... ).
Pinguino is the hardware part of this project.

8 PWM output on Pinguino !!

This is an interrupt code example. It show how to build 8 PWM output on pin 0 to 7 with the timer 1. The PWM frequency is about 400 Hz. With the 2 analogWrite output, you can now drive 10 PWM outputs and this code can be adapted to drive 16 PWM outputs.
Applications are motors, lights and others analogic outputs.

// How to use interrupt on Pinguino
// add 8 analog outputs ( PWM ) to your Pinguino
// can be extended to 16

CodeBlocks model Released !!

CodeBlocks model for Pinguino released to be conform to beta 5 of the IDE.
The new file can be downloaded here..........

How to use Interrupt with Pinguino......

With beta 5 you can use interrupt in a Pinguino program. This is a simple example to blink a led with timer 1. Nothing to do in the main loop because level of the led is changed by the interrupt routine.

// How to use interrupt on Pinguino
// simple example blink a led with timer 1
// led is connected on output 0
// Jean-Pierre Mandon 2009

void UserInterrupt()
{
// timer 1 interrupt flag in register PIR1
if (PIR1bits.TMR1IF)
{
// reset interrupt flag
PIR1bits.TMR1IF=0;
// reverse state of pin 0 ( blink )
digitalWrite(0,digitalRead(0)^1);
}
}

void setup()
{
// led is connected on output 0
pinMode(0,OUTPUT);
// timer 1 configuration
// you can write T1CON=0xB1; or
// timer1 register is 16 bits
T1CONbits.RD16=1;
// clock source for timer 1 is derived from clock
T1CONbits.T1RUN=0;
// prescale value 1/8
T1CONbits.T1CKPS1=1;
T1CONbits.T1CKPS0=1;
// timer 1 oscillator is shut off ( internal clock )
T1CONbits.T1OSCEN=0;
// T1SYNC is not used ( internal clock )
// timer clock is internal clock ( Fosc/4 )
T1CONbits.TMR1CS=0;
// timer 1 is On
T1CONbits.TMR1ON=1;
// FOSC is 48 Mhz => Internal clock = 48 Mhz / 4 = 12 Mhz
// clock period is 83 nS
// prescale for timer 1 is 8 => clock period for timer 1 is 667 nS
// timer 1 is incremented every 667 nS
// timer 1 is a 16 bits register, it will overflow every 667nS*65536 = 43.6 mS
// when timer 1 overflow it generate an interrupt
// Interrupt configuration
// enable interrupt for timer1 in register PIE1
PIE1bits.TMR1IE=1;
// Here you can write INTCON|=0xC0; or
// enable peripheral interrupt
INTCONbits.PEIE=1;
// global enable interrupt
INTCONbits.GIE=1;
// now an interrupt will be generated by timer1 every 43,6 mS
}

void loop()
{
// nothing to do in the main loop :-)
}

Pinguino with Processing

I tried to connect Pinguino with Processing with the LibUSB java wrapper. It works without problem. This is the Processing test sketch:

// This is a simple example to communicate with Pinguino
// based on the LibusbJava wrapper http://libusbjava.sourceforge.net/wp/
// Jean-Pierre MANDON 05/03/2009

import ch.ntb.usb.Device;
import ch.ntb.usb.USB;
import ch.ntb.usb.USBException;
import ch.ntb.usb.logger.LogUtil;

// define Pinguino Product ID and Vendor ID
int VID = 0x04D8;
int PID = 0xFEAA;
// declare public USB device
Device Pinguino;
// declare output buffer
byte[] data = new byte[] { 'W', -1 };

void setup()
{
size(400,100);
frameRate(20);
LibusbJava.usb_init(); // init libusbjava
LibusbJava.usb_find_busses(); // find all usb busses
LibusbJava.usb_find_devices(); // find all devices
try {
Pinguino=USB.getDevice( (short) VID , (short) PID ); // create a new device
Pinguino.open(3,0,-1); // try to open it ( configuration 3, interface 0 )
println("Pinguino found"); // it's OK
}
catch (USBException e) // error
{
println("Pinguino not found"); // Pinguino is not connected !!
}
}

byte lastposition=-1;
byte position;

void draw()
{
background(204);
rect(mouseX,40,20,20); // draw a rectangle
position=byte(mouseX/50); // position modulo 8
if (position!=lastposition)
{
try {
if (lastposition!=-1) data[1]=lastposition;
else data[1]='C'; // WC clear all leds
Pinguino.writeBulk(0x01,data,2,200,false); // send command to Pinguino
data[1]=position; // led to be lighted
Pinguino.writeBulk(0x01,data,2,200,false); // send command
lastposition=position;
}
catch (USBException e) {}
}
}

void stop()
{
data[1]='C'; // clear all when stop
try {
Pinguino.writeBulk(0x01,data,2,200,false);
}
catch (USBException e) {}
}

Now this is the Pinguino side:

// test Pinguino with Processing
// Jean-Pierre MANDON 2009

int i;
uchar caractere,caractere1;

void setup()
{
for (i=0;i<8;i++)
{
pinMode(i,OUTPUT);
digitalWrite(i,LOW);
}
}

void loop()
{
if (USB.available())
{
caractere=USB.read();
if (caractere=='W') if (USB.available())
{
caractere1=USB.read();
if (caractere1=='C')
for (i=0;i<8;i++) digitalWrite(i,LOW);
else
digitalWrite(caractere1,digitalRead(caractere1)^1);
}
}
}

And you can see the result here.

Pinguino with CodeBlocks............

Pinguino can be used with CodeBlocks. To do this, you need to install SDCC and GPUTILS. CodeBlocks recognize if SDCC is installed.
First you must download the CodeBlocks model for Pinguino.
Then you have to configure CodeBlocks to work with SDCC.

Create a new empty project in the same folder than the CodeBlocks model,
Go to the Settings menu/Compiler and debugger and choose SDCC in the Selected compiler panel,
Click the compiler settings tab and Compiler flags tab and select:
  • Be verbose
  • [CPU] PIC 16 bits
  • ouput intel hex
Select the Other Options panel and type:
  • --optimize-goto --denable-peeps --obanksel=9 --opt-code-size --optimize-cmp --optimize-df
Then all the general settings for the compiler are OK. You must now configure the specific options for Pinguino.
Select the Project/Build Options menu,
Click on the Compiler Settings tab and Other Options tab,
type -p18f2550 in the field.
Click now on the Linker Settings panel.
In the Other Linker Options field, type:
--no-crt -Wl-s18f2550.lkr,-m
In the Link Libraries field, click on add and select this files:
libpuf.lib wich is in the project folder,
libc18f.lib wich is in the /usr/share/sdcc/lib/pic16 folder ( Linux )
libio18f2550.lib
wich is in the /usr/share/sdcc/lib/pic16 folder ( Linux )

Now you can click on the Build button and an hex file should be generated.
All the code must be written in the application_main() in main.c

To upload the code to the PIC, you can use the Python downloader wich can be downloaded here.

I hope to propose some models of applications.

Pinguino/LA FONERA serial interface



La fonera work with a 3,3V power supply. This assembly converts levels from 3,3V to 5V for Pinguino and from 5V to 3,3V for LA FONERA. The Fonera serial connector is inside the box, on the right side.
Be careful, this Pinout is only for FONERA 2100.

Pinguino with LA FONERA


we worked Friday with Benoit espinola on the link beetween LA FONERA and Pinguino. It Works !!
The FONERA was flashed with openwrt 7.09 and the ser2net package was installed. A small interface was build to convert 3,3V signal from the ttyS0 to 5V for the PIC UART.
The last step is to link a FONERA 2 with Pinguino but it seems that i must write a driver for USB.
Benoit Espinola wrote a small processing sketch to test the link:

import processing.net.*;
boolean onoff;

Client c;
String data;

void setup() {
size(200, 200);
background(50);
fill(200);
onoff = true;
c = new Client(this, "192.168.1.1", 2001); // Connect to FONERA on port 2001
c.write("W01"); // write W output (0) state of the output (1)
// this is the protocol we defined in the pinguino program
}

void draw() {
if (c.available() > 0) { // If there's incoming data from the client...
data = c.readString(); // ...then grab it and print it
println(data);
}
}

// press the mouse change the state of the output

void mousePressed(){
onoff = !onoff;
c.write("W0" + int(onoff));
}

// the led is darked when program stop

void stop(){
c.write("W00");
}

Nice job Benoit !!
