CCS: no issue

hello

I have to ask that , is it possible for adcbuffcontious_msp432p4111_tirtos_ccs program to take 10k samples per second without removing uart configuration?

Hi Kalpana,

It should be possible considering the ADC supports up to 1 Msps; however, 200 Hz was chosen for easily interpretable output.

Thanks,

Alexis

hello Alexis,

Thank you, for reply . You are right but when i set the frequency for 10k samples per second,some buffers somewhat 6 are missed by adcbufcontinous_MSP_EXP432p4111_tirtos_ccs. so please tell me what kind of changes i have to make in the program for 10k samples . I have made all possible changes in the program but all the time i am getting missed buffer.

Thanks,

Kalpna

Hello,

by using this fs=10fm we are not getting the desired output, getting distorted wave and buffer are also missed. Please tell me what kind of input i have to give to take 10k samples per second?

thanks.

Hi Kalpana,

What UART baud rate are you using?

Thanks,

Alexis

Hi Alexis,

The baudrate , i am using is 115200 but i have also tried to change the baud rate in adcbufcontinous_MSP_EXP432p4111_tirtos_ccs to 460800 with the help of datasheet but it is not working.

Thanks,

Hi Kalpana,

Yes I believe in this case your UART is the limiting factor. You'll be able to take 10k samples per second, but probably not be able to send out every sample via UART.

Thanks,

Alexis

Hi Alexis,

Thank you , yes there is a limitation in uart therefore i removed the uart but now i am facing the new problem which is i am not getting the sine wave when fs x 10 from the fm (input frequency) . Is this the problem of adc conversion?. Please refer the attachment.
