Experiments with the PIC32 based UBW32 board

June 13th, 2010

The board uses a bootloader that lets you use a terminal program (e.g. minicom, ZTerm) to execute simple commands.

New project idea: btstack on a stick

March 21st, 2010

The idea is to have a simple method for firmware updates - e.g. with a built-in bootloader and dfu-programmer.

New idea: btstack on a stick

Might use an AT90USB1287 (on an ATMEL USB Key) or an ATMega2560 board.

Experiments with CC1101 radios

March 20th, 2010

I have modules operating at 433 MHz as well as 868 MHz

CUL 433 MHz

Programming is done via the dfu-programmer software - just tested it on OSX.

I’m stepping forward with the process - can flash individual software on the remote now.

Stepping forward with Arduino Bluetooth communication

February 7th, 2010

The video shows that changing the display state can either be done locally (by pushing a button) or by receiving data via the Bluetooth RFCOMM link. On a state change data is also transmitted via this link. For the Arduino this is done by just using the serial port.

See the Arduino code below:

#include <S65Display.h>

S65Display lcd;
int state=0;

const int button1_pin=2;
const int button2_pin=3;

void drawText_0(void)
{
  lcd.drawTextPGM(30, 50, PSTR("State 0"), 2, RGB(0, 0, 255), RGB(255, 255, 255));
}

void drawText_1(void)
{
  lcd.drawTextPGM(30, 50, PSTR("State 1"), 2, RGB(0, 0, 255), RGB(255, 255, 255));
}

void setup()
{
  state=0;
  //init LCD
  lcd.init(4); //spi-clk = Fcpu/4

  //clear screen
  lcd.clear(RGB(255, 255, 255));

  drawText_0();
  pinMode(button1_pin, INPUT);
  pinMode(button2_pin, INPUT);
  Serial.begin(9600);
}

void loop()
{
  static byte recvd_byte=' ';

  if (Serial.available() > 0)
  {
    recvd_byte=Serial.read();
  }

  if ((state == 0) && ((digitalRead(button2_pin) == LOW) || (recvd_byte=='1')))
  {
    state=1;
    drawText_1();
    Serial.println("State 1");
    recvd_byte=' ';
  }
  if ((state == 1) && ((digitalRead(button1_pin) == LOW) || (recvd_byte=='0')))
  {
    state=0;
    drawText_0();
    Serial.println("State 0");
    recvd_byte=' ';
  }
}
