read CRC from E-paper Display

[shahar_c]

Hey,

I try to read the CRC from E-Paper display series 1.02 inch (GDEW0102L4f) with no success (I'm working with nRF52833 Development Kit)

My code and the official Goodisplay data sheet are included  

Thanks!

Hi,

What do you mean by "no success". What is the output of NRFX_LOG_INFO?

I believe you have to declare the lsb, msb and rx variables as static. If not they will be lost as soon as the read_crc function returns, and not available for the logging module. Like this:

static uint8_t rx;
static uint8_t msb;
static uint8_t lsb;
