i am trying to receive DMX512 signal on my stm32F103 Board but initially i just wanted to see if the interrupt is working , but it did not , so i saw if there is any Framing error but the SR was 192 , which suggests that there is no errors in the frame that is an odd behaviour , i am sending the DMx data from esp32 which when connected to light is working fine that means there is nothing wrong with the sent dmx signal also using rs485 which and getting the data in usart3 of the stm microcontroller , i have set the baudrate to 250000 , 8 bits and 2 stop bits , i am new to stm and do know a lot about it , so please can u guys push me in the right approach path .
