Micro-controllers, wireless transmission and database
This project assumes you have already installed STM32CubeIDE. You need to have previously done a basic blink sketch with blue-pill using STM32CubeIDE. I have made a complete video from installing STM32CubeIDE to LED blink program. You can watch it by clicking this link. https://www.youtube.com/watch?v=kXg467nVd_A
Set PA1 to GPIO_Output
Set PB9 to GPIO_Input
/* Infinite loop */ /* USER CODE BEGIN WHILE */ while (1) { if(HAL_GPIO_ReadPin(GPIOB, GPIO_PIN_9) == GPIO_PIN_RESET) { HAL_GPIO_WritePin(GPIOA, GPIO_PIN_1, 0); } else { HAL_GPIO_WritePin(GPIOA, GPIO_PIN_1, 1); } /* USER CODE END WHILE */ /* USER CODE BEGIN 3 */ } /* USER CODE END 3 */
