Hi all,
I have 2 questions related to the timing in TinyOS: 1. I implemented a TDMA MAC protocol in TinyOS 1.x. When executed in the nodes (Im using a MSP430 microcontroller and a nRF2401 radio chip), the protocol performed without any problem. But when I tried this protocol in TOSSIM I found a lot of problems due to the timing (the timers that control the TDMA protocol, that have to be quite precise, do not fire when they are supposed to fire). Im thinking of porting to TinyOS 2.0. Shall I have the same problems with the timing in TOSSIM for TinyOS 2.0? 2. I need a sampling frequency of 32KHz for the sensor that Im using. I was completely unable to implement the driver for the sensor in TinyOS 1.x to fulfill the requirements of such a high sampling frequency. Shall I have the same problem in TinyOS 2.0? I have read that with TinyOS 2.0, I can have access to the hardware timer using the Alarm interface (that is async). Can I solve the problem by using the Alarm interface instead of the Timer interface? Thanks in advance. Regards, Fran Rincón
