PIC like interface with an AVR

[alexraws]

Hi,

I am looking for the format of the serial data you need to send FMS in order to use the PIC interface. Where would I find information. I am planning to implement this on an AVR microcontroller from ATMEL.

Have a look at the files in the DOC directory of FMS Beta 7. You should find the PIC code easy to understand and hence make an AVR alternate. In broad terms with the 19,200 baud format (why bother with 9600baud) the sync pulse is sent as hex 'FF' and each other pulse is sent as an 8 bit number where zero is around 0.86ms and 2.14ms is hex 'FE' - i.e. binary 1 = 5us. At 19,200 baud the data can be sent during the initial 0.86ms of the next pulse. I hope this helps.

Setup info etc on my website.

Thanks Mike,

I had a look last night and found the info. I will post the AVR solution as soon as I have done it for those who want it.
