Hai experts,

I am using F28335 custom board with 20 Mhz crystal oscillator.

CLKINDIV is 2 and PLLCR is 10.

I am using ADC module.

I have to find the time of each conversion.

So i checked the demo code in Control suit.

actually demo code is working properly.

But in that where i could see the counter values.

how can i see the decremented Values? Then only i can find the time of each conversion.

I am expecting valuable information.

Thanks in Advance

Hi Akhil,

You can monitor the cpu_timer register in Global Variables under Expression window.

Hi Gautam,

Thanks for your reply.

It worked properly. i got the counts from ReadCpuTimer0Counter(); function.
I given the period is 100.
How can i convert this counts into time in seconds.

Thanks in Advance

First of all- you need to check the units of these counts. Generally the CPU timer configuration are in terms of CPU clock cycles. For example for F28335 @150MHz clock, 1 cpu_count or tick = 6.67ns
