The below code also needed to have the FSIN and FCOS (V2 code) updated to read SIN and COS.

The chip has pretty much been Tue, 18 Aug 2009 15:11:26 GMT peterverkaik http://tech.groups.yahoo.com/group/uMFPU/message/335 http://tech.groups.yahoo.com/group/uMFPU/message/335 Hi Cam, I feared so. But the idea of auto-calling a userfunction after sampling ADC via timer, could that be realized for the next firmware update?

There are tasks performed in the background by some instructions, but actual instruction Mon, 17 Aug 2009 22:40:00 GMT peterverkaik http://tech.groups.yahoo.com/group/uMFPU/message/333 http://tech.groups.yahoo.com/group/uMFPU/message/333 Hi Cam, Thanks for the correct assembly statements. You said if the function is called with wdt=0, it will loop continuously in loop1 and never return.
