Hi all, Do anyone know what happened if we use return statement inside isr. isr() { some codes..; return; } Also can we pass any arguments in isr function?

Hi Tufan! Did you check if the startConversion()-function is called inside the timer ISR? Dennis

Hi Prakash! Normally an interrupt is not meant to receive or return anything since it is called by hardware. You can use global variables declared as volatile to exchange data with the interrupt...

You cannot implement software timer without help from hardware timer. So you shall get familiar with hardware timer first, build code that calls timer interrupt service routine (ISR) 100 or 1000 times...

I think you need to clarify your question a little bit. However, given the function name, "isr", lets assume that you are asking about interrupt functions. For example: __interrupt void isr(void) { if...

Thank you for your kind reply Dennis. As per my problem, yes start and stop conversion functions are called and executed but adc12 never hits the isr.I think my problem is that I have to hard wire...

You can use DMA for measurement part too - so both DAC and ADC is running without CPU intervention. DMA does not halt CPU (!!!), It does stop bus briefly. If we assume that each DMA transfer takes 2...
