I am working on a healthcare project where we are using a load cell.
We have a Nordic nrf51 series bluetooth chip with several peripherals up and running. We are using openocd and 2 pins to program it.
We need to connect also a load cell to the ADC and perform the calibration and perform careful testing with this load cell to study its drift and errors.
Since it's a hardware / embedded systems project, we might need to meet up to give you the hardware and share the code.
