[Tinyos-help] Wireless two channels sensor

2007-03-19 Thread Nicolas de Vicq
Hello, I'm working on a wireless sensor. My sensor has two channels connected to the 12 bits ADCs A0 and A1 of the MSP430. I have to write a driver for read the data on the two channels at 1Khz and to write it in a data frame send to the radio buffer. My idea is to organize the data like

Hello, I'd like to generate a 125 kHz clock in TinyOS 1.1, using the PWM abilities of the MSP430. Does somebody know how to do that ? Thanks in advance for your help ! NDV ___ Tinyos-help mailing list Tinyos-help@Millennium.Berkeley.EDU

[Tinyos-help] 128 kHz clock

2007-03-12 Thread Nicolas de Vicq
Hello, I'm working with TinyOS 1.1 on a small sensor node using the MSP430 microcontroller. I need to provide a 128 kHz clock to my front-end chip (chopping amplifier). So, I want to take the 8 MHz signal from the MSP430 XTAL input and to divide it by 64 for having the 128 kHz. It seems to
