Hi ,I have connected switch to PC2 and PD2 (the are acting as gpio input),after trying to generate initial code using cubemx found that these two pins are on same gpio interrupt EXTI2 line , so cubemx is not allowing to have interrupt on both pins,is...
Hi,I have a STM32F407 Discovery kit, I'm working on costum bootloader program. I writed my codes, make the necessary changes in the Flash.id file with CubeIDE. I want to write bootloader section (0x1FFF 0000 address system memory) with STM32 ST-Link ...
I'm using SPI Protocol in two STM32F407ZGT6 , one master and one slaveBoard has 3.3v LDO regulator and Input Voltage has 5vWhen power supply connected SPI program correctly work but in this case when disconnect SPI wires and connect again we face of ...
I wonder how many of you agree with me about the needed documents when playing with STM32s?I'd say, one needs 3 documents:the data sheets of your devicethe reference manual of your devicethe ARM Architecture Reference Manual of your deviceThose cover...
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 ...
