Codewarrior debugger to simulate ADC

suma_success — Sun, 12 Apr 2020 08:23:45 GMT

I need to use the visulaisation tool to simulate ADC in Codewarrior v5.1 . Please help. I do not have the trainer board.

Suma,

CW for HCS12 v5.1 visulaisation tool doesn't have component for ADC.

debugger can simulate ADC, I suggest you check debugger help manual with key word "Analog to Digital Converter Module"

Have a nice day,

Thank you so much for your kind help.We are unable to provide trainer boards to our students, hence I had another question. Have you tried RTI interrupts in full chip simulation mode?

Thanks in advance,

Suma

What specific problem do you have with RTI simulation?

please send me your problem screenshots and demo project.

Thank you. It's a basic counter with RTI interrupts. The isr vectors.c and the vector start up in the prm file have a linked error. After, I removed vector startup in prm , I found the code working. This is an issue with full chip simulation mode. However, with timer interrupts just adding the isr vectors.c is sufficient. I am confused about this setting for each kind of interrupt. Also I copied the isr vectors.c , source file from Codewarrior examples folder and have used the visualisation tool for all simulation.

Regards,

Suma

Suma,

I attach a CW for hcs12 v5.1 RTI demo code to you. the RTI can work well in simulation mode. Just FYI.

Have a nice day,

Dear Jun,

Thanks a bunch.

I just modified your code to toggle LED connected to PORTB in the visualisation tool with a delay generated by RTI . The code debugs , but the LED does not toggle.

REgards,

Suma

#include <hidef.h> /* common defines and macros /#include "derivative.h" / derivative-specific definitions */

int counter;

void main(void) { /* put your own code here */ DDRB=0XFF; counter=0; RTICTL= 0x51; CRGINT = 0x80; // enable RTI interrupts EnableInterrupts;

for(;;) { FEEDCOP(); /* feeds the dog / } / loop forever / / please make sure that you never leave main */}

#pragma CODE_SEG __NEAR_SEG NON_BANKEDvoid interrupt 7 RTI() { if (counter==500){ PORTB=0b00000001; } else{ counter++ ; } CRGFLG = 0x80; } #pragma CODE_SEG DEFAULT
