Bonjour,j'ai un système communicant avec des cartes identiques possédant des modules STM32F411 CE8 black pill . une carte est maitre et les autres cartes sont toutes esclaves. je suis en mode "UART_TwoBoards_ComPolling"mon IDE est STM32IDE avec les ...

I am French.There is now more than one week that I try, see youtube and some comments on forum. I need your experience for solving the initialisation of a "simple" PWM.Thanks in advance.Joëlhere under my code. in the main I have launch : PWM1_CH3N_se...

I write a second message because I don't understand why I cannot use UART_INTERRUP because I have a error handler. due the error handler i use the prvious solution with a second IO in interrupt mode.Joël

Hello,I try to use another pin connected to Rx pin. this second pin PB0 is in GPIO_EXTIO mode.I put the HAL_UART_RECEIVE() function in the EXTI0_IRQ handlerreceived framereceived frame in rx buffer is allways good whitout rotation in the data. ...

Thanks for your quick answers.I made à very simple program herunder on master and slave. between master and slave I have a cable with 30cm lentgh Slave program while (1) { /* USER CODE END WHILE */ //code dans le slave /*...

Thanks you TDK . The uart is an asynchronous system and i don't use RTS and CTS.For you how can I synchronise Tx and Rx ?regards. Joël

I JW; I have found with your questions , "&Timhandle" is wrong , I need to use "&htm1"I have tested and now I have output on PF0 . This is that I need . I don't need PC2 . I have used PF0 and PC2 for tring only.here under the final code for 38khz PWM...

STM32F411 Blackpill : fonction HAL_UART_Receive(UART_HandleTypeDef huart, uint8_t pData, uint16_t Size, uint32_t Timeout)

using PWM function in STM32F302R8 nucleo board. [ SOLVED] I can't start PWM function . most of my code has been made by using Cube. I see nothing in ouput PC2 and PF0 for TIM1 chanel 3 and 3N.
