I2C & SPI not working together (STM32F303K8)
Hi, I am trying to simply output information from an I2C device (DS1307 real time clock) to an SPI screen (ST7789) I have tested the code & libraries for the separate devices and they work but as soon as I try adding any SPI commands to the main.c th...
hello, USART read doesn't work on nucleo board.
I am using stm32u575zit6q. I set Baud Rate 2500000bit/s.(my equipment is only support 2500000bits)usart write is work successful, but read is not.usart read work only 9600bit/s.How do I use the read to work over 9600baud rate?
