Good day
My issue is related to functionality of the sensor controller. Since OS im using is taking too much of a controller time i cant manipulate with General purpose timers (i also tried RTC) to count values up to 30 usec correctly. So i took a look at AUX and found out that there are two timers up there (one is 16 and one is 8 bit, which is more than i need). But im struggling with interupt that Timer 0 is generating after the count is completed. The algorithm is: to enable timer, to leave all register fields of it as 0 (which is manual reactivating, a common counting, not attached to any of the events) and set prescaler to 2; then im forwarding timeout event from aon to MCU programmable event 0 and here is the place where my code stops working. After uploading hex file the code stops right b4 enabling MCU_programmable_event0 as interrupt (despite of the timer configuration, was it or was it not configured before). But here is the thing after i reset my chip the program starts working and enables handler exactly 37 times (magic number?). Im sure im missing something. The code for contiki OS is attached below. I would be very glad if some one suggested a solution for me.
P. S.: handler should've been activeted just once if all configs were right.
