[Tinyos-help] Problem with I2C on MicaZ under T2

Hi all, I'm trying to communicate with a I2C device using MicaZ (MicaZ is the master) but have encountered some strange problems as described below. Does anyone have any ideas? I wrote a very simple program that basically write a byte to the I2C device (code shown at the end). The

ankur, I have seen this error before when I was compiling my I2C program for tmote. I fixed it by reinstalling the toolchain. I'm not certain about the exact part but most likely the msp430 toolchain. Also you might try installing moteiv's version. hope that helps -Fred - Original

ankur If I remember correctly, Tinyos-1.x's implementation of I2C is not correct / complete. It does not address arbitration appropriately. Moteiv's implementation (i.e. boomerang) uses the resource abstraction for usart arbitration and therefore more fully support I2C. Tinyos-2.x has also

hardware (e.g. CPU) requirements largely depends on the actual code / application running on it, notably the RAM and ROM requirements of the application. ATmega32 should be fine for most small applications. For example, the ultrasound ranging board (http://www.tinyos.net/

At this point, the best way is probably hook up a small shunt resistor (1-50Ohm depending on your load and oscilloscope accuracy) in series between the battery and the board, either on the ground side or the Vdd side. Then use an oscilloscope to measure it. Also pay attention to the

I don't think there is a guide on it. Although you probably should look at the existing sensorboard designs on http://www.tinyos.net/ scoop/special/hardware. It's probably best to copy after a corresponding design depending on which main board you want your sensorboard to interface with.
