I've bought a dozen of these chips. When I tried to programme them I found some abnormal behaviors.The first one is sequence needed to run the chip for the first time. It is not possible to run anything on chip for the first power on. It's like if it...
Hey guysI'm using a STM32H743ZIT6 on a Nucleo-144 Dev Board and want to communicate with a BME280 Sensor.For this I'm using a library recommended by somebody else and when I begin the I2C transmission the chip sends the correct address, however, the ...
I already have a compiled HEX file and I have already done downloading HEX files to STM32 using my PC using Keil and ST-LINK. Now I would like to download the Hex file to STM32 only on a hardware basis in a more advanced way, without PCs and programs...
Hello. I have this init TIM3:void Start_Timer_3(void) { LL_TIM_InitTypeDef TIM_InitStruct; LL_APB1_GRP1_EnableClock(LL_APB1_GRP1_PERIPH_TIM3); NVIC_SetPriority(TIM3_IRQn, 3); NVIC_EnableIRQ(TIM3_IRQn); // 50MHz clock // 1000 Hz, up...
The MCU is STM32F401CB.VDD is 3.3V.A few buttons are connected to PA0 (configured as EXTI rising/falling interrupt).When a button is pressed, the IRQ always comes.When a button is released, the IRQ comes rarely, if at all.There's a filtering cap and ...
Hello everybodyI am a student trying out some things with the evaluation board STM32F769I-EVAL.First, I think it is important to say that I have nearly no experience with STM controllers.So, let's look at my problem. The main aspects I am looking at,...
Hello, I work on STM32F407.I want to start the PWM 1 on the rising edge of the main PWM and start the PWM 2 on the failling edge of the main PWM. But I don't know how I can detect the rising/failling edge...Can you help me please ? Thanks a lot.
Posted on June 13, 2018 at 21:06 Hi, I am using Nucleo-144 connecting CAN RX/TX PD0/PD1 to external CAN transceiver, PEAK. The function is pretty straight forward. Prepare data then call HAL_CAN_AddTxMessage() to transmit. CAN_TxHeaderTypeDe...
Hello everyone,I have a development board with the MCU specified in the title. I have used Keil to create a project and flash my board. According to what I understood from the documentation I read and by looking at the startup code:MCU is by default ...
Hi All,I am working with the STM32F302R8. I want to set the system clock as the PLL through derived from the HSI. I want a clock of 64MHz which I should have set through the appropriate registers.I think I have set all I need however, after the RCC c...
