Reg: EVM and ADC - abdul salam - Dec 26 11:53:29 2007



hi,

   i am using dsp tmsc320f2812, i had one doubt regarding the
 ADC and EVM i.e., how can we use the EVM with ADC. in my application i need to trigger   an
single phase inverter using pwm signals of EVM. i
 wrote some code to evaluate my algorithm. but i had doubt that will it
 work or not? how can i cross check each step of my code? coming to the
 point, in my application i used the ADC ISR, in that routine i will
 read the analog signals and then call the ev_pwm function in which i
 will enable all registers and get the pwm pulses for every pwm
 reloaded value in compare register. will it work or i had to use some
 other interupts in the ev_pwm function, to function it properly. i had
 taken the ev_pwm function from the example from the TI f2812 examples.
 one more doubt from ADC, what is SHCLK (sample hold clock) in ADC, how
 to get it? i did not understand this SHCLK, how to determine my this?
 in my application i need to sample two signals one at 100microseconds
 another at 200microseconds. how to sample these signals, whether i had
 to use the same sequencer (seq1 or seq1 and seq2) ? can you plz help
 me regarding this. any help here is highly appreciable.

                                 Thanking you sir,
   
  sincerely,
  abdul
