I am trying to communicate to a e-paper display of waveshare 1.54inch v2 with B-WL5M-subg1. I have used the program file the company has provided but there is no respone in the module. I have tried using esp32 and the module works fine with it. both esp32and stm32 uses same program file while checking with logic analyzer both mcu show similar data format. But why isnt it working with stm32. I have attached the program for referense if there is any suggestions or solutions I would like to know.
