INTERFACING LOAD CELL WITH STM 32 F4 #7

Demonstrate how STM32F4 instead of LPC 1769 can resolve the issue connecting the load cell to the MCU

ankitpatel9300 commented 4 years ago

Depending on MCU frequency, Maximum GPIO pin switching is different. We tried with LPC1769 but can not read the proper value from the HX711 IC(i.e LoadCell). When we tried it with STM32F4 MCU, with similar code it worked. The possible reason for this could be GPIO switching speed due to different frequencies. To correctly measure timings, we need a logic analyzer, which is not possible due to the current situation.

That's why we tried to interface Load Cell with STM32F4 and is working correctly.

  1. what issues did you or others might face with connecting the load cell to the STM32F4 in terms of hardware and software?
  2. how did you resolve them?
