I have a problem by using the timer T6.I downloaded the apnt_115_p1 and included the timer-files to my current project.It worked - but only while I was debugging.When I tried to flash the hex-file, I lost all the functionality. When I tested the timersript whithout hardware (to understand how it realy works) it seemed to be easy: It produces periodic int.req.(in the way the timer is initialized) - But I don't understand why there is no jump into the ISR when a reguest is given ?!? Is there no int.ack.?!? (global interrupts are enabled!) I think I have a problem by using and understanding interrupts :-). Please help me !
Which hardware did you use for testing? Also does your program run in the simulator?
Hi Chris, to use timer 6 interrupts you will need to ... - implement an interrupt function for timer 6. - set timer 6 interrupt priority and enable the interrupt. - enable all interrupts. - set timer 6 mode and start the timer. In C, it would look like this: void timer6_int (void) interrupt 0x26 { /* do something ... */ } void main (void) { T6IC = 0x44; /*T6IR=0, T6IE=1, T6ILVL=1, T6GLVL=0*/ IEN = 1; T6CON = 0x47; /*T6R=1, T6M=0, T6I=7*/ while (1); /* timer 6 interrupt should occur every 1.34s (with 25MHz CPU) */ } The linker should generate an interrupt vector table entry for timer 6. You can verify this by looking in the linker output file *.m66 in the "memory map" section. Make sure that compiler and linker do not prompt warnings or errors.
In my project I use the PHYTECMO -EVALUATIONBOARD whith a c167crlm. For testing the timerfunctions I used only the simulator(no hardware).
Hello Holger, Thank U for the "to-do-list". It was really helpfull. I checked everything and uuups... I lost the code "IEN = 1" somewhere !!! It works now (in the simulator). Let's see if it works flashed, too (next days). Thanks a lot Chris
