Best approach to interface HX711 with Nordic nrf52832?

I am working with HX711 and I am trying to interface with nrf52832. Should I proceed with SAADC example or UART or Twi Sensor

Hi, Please refer to the datasheet for the hx711, it does not use a standardized serial interface such as UART or TWI, which means that it has to be implemented in software (i.e., bit banging). We don…

Hello, Unfortunately, the code was written for the nRF52 series. The same approach will not work on the nRF51 series as it doesn't have the PPI "fork" feature. Have you decided on using the nRF51? nRF52810…

user75535 , the hx711_sample() function needs to be compiled with optimization to work when PD_SCK frequency is 1MHz. I suspect it would not have been necessary if I had rewritten this line "m_sample.value…

Good afternoon. I am totally new to programming with controllers ARM Cortex M-4 and I need to do to operate the ADC HX711 in a Nrf52DK without the use of Ble. I have searched to the best of examples for the forums and I have not solved my needs. I can only find examples of Main c. for use with Ble. Someone could help me to build the file Main c. to be able to read the HX711 through NRF_LOG_INFO? I appreciate deeply the help.
