how to force STM8S003 MCU to set UART1_RXNE_flag when receiving byte

standard IAR program. Transmit works normally ( without interrupts ).Receiving doesn't work not with flag polling, not with interrupt. I have seen in Internet similar questions, but no one answer with reasonable explanation or unconditionally working...

Loading value directly in the Index register "XL"

I am using STM8S103F2 controller in assembly language. I want to load directly value in "XL" index register in one instruction and i do not want to affect "XH" register. (Index "x" register is the combination of XH and XL). Other ways to load value i...

STM8L001J3 and SWIM pin

I was using STM8SVLDISCOVERY in a small project because it was the evaluation board that I had, but in a more final stage I would like to use an stm8sl001j3 as uC.For that, I got a STM8-SO8-DISCO to be able to use the same uC that I want in the final...

How to use UART at STM8L050j3?

Hello,Using STM8L050j3, ST LINK/V2 ISOL, STVD.I am studying the UART and i have connected MCU and ST LINK/V2 ISOL.They use SWIM with USART TX / RX Pin.A problem is that PC don't receive the any text.​I think that cording is fine(easy example) but i s...
