Pinout for the NUCLEO-F767ZI to use the HX711
Hello,I’m currently working on integrating the HX711 load cell amplifier with my NUCLEO-F767ZI development board. However, I’m having some difficulty determining which GPIO pins to use for the SCK (clock) and DT (data) lines.As I’m relatively new to ...
Resolved! How to add delays between I2C bytes to support TI mct8329a / mct8316
The TI motor drivers mct8329a and mct8316 require 100us delay between i2c data bytes. This can't include the acknowledge bit, but requires holding down the clock between transfers for the 100us. it is due to a bug in the TI chips that can't stretch c...
