Part Number: TMS320F28035
Hi
I am working base on TMS320F28035,
I want to calculate the duty and frequency of pulse by HRCAP, I can calculate above 1 kHz signals properly but I can't calculate below 1 kHz signals. (SYSCLK is 60 Mhz)
Where is the wrong?
Thanks
Hi,
Apologies for the delay in response. You can measure the frequency of 1.5KHz with accuracy. Kindly refer to this thread: (+) TMS320F28034: HRCAP - C2000 microcontrollers forum - C2000
︎ microcontrollers - TI E2E support forums. As HRCAP registers are only 16 bit wide, you can use eCAP which has 32 bit registers for slower signals.
