The propeller chip boots up first checking for a connected PC on the serial port, then it checks an i2c EEPROM for a program to load. Now suppose we can make the Bifferboard serial console behave like the Propeller-programming component of the PC. I have several SPIN programs that connect the propeller to the serial (via PCF8574) HD44780, but would really like to use C or C using I2C. I'd be particularly interested in anyone who has accomplished this especially if they've also managed to measure temperatures with the DS18B20 and/or any other type of sensor (gas etc). A flip is a mini board similar to the MICRO but powered with a parallax propeller running at 5-80 MHz. The freq is set by PLL and has 8 processors in a single chip. I originally planned on starting with I2C questions and may still return to I2C.
