Hi I am facing one issue I am trying to run Timer2 and as soon I have enable the by setting CR1 register bit CEN, My all flags in SR is getting set even I have enabled only(UIE) so my UIF flag bit in SR register must set but it is setting all (CC4IF...
Can any one please assist me.I have all 8 ADC down to GRND 0V I am using this command:HAL_ADC_Start_DMA(&hadc1, AD_RES_BUFFER, 8); The arry is:volatile uint32_t AD_RES_BUFFER[19] = {0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0}; All 8 AD...
iam working on stm32h7a3zi controller in that datasheet they mentioned up to 164 I/O pins capable of 5V tolerant but they didn,t mentioned about which pins are capable of 5v tolerant
When I program my STM32WLE5 using STM32CubeProgrammer and UART, a simple push on the reset button does not reset the MCU.I always need to power-cycle it.Why is the reset-pin not working, or why does it not start the application ? Is there a way to c...
Dear ST, Will you be releasing a variant of the H5 with both USB HS support and hexadeca/hspi/xspi support?It seems confusing that your U5 series supports this but your higher speed more performance range doesn't. Thanks.
How about the lifecycle of the STM32L151? We are designing a new project. Is it available in another 15 years?
As given on datasheet this microcontroller can support 10/100 Base T Ethernet. Is there any probability that this microcontroller supports Gigabit Ethernet and if yes, please provide the recommended circuitry for the same.
Hi everyone,I'm working with the STM32F030 and recently ran into a hardware limitation that I unfortunately discovered only after designing my custom PCB:I'm using PA4 (TIM14_CH1) to control an LED driver (like SM16126 or WS2812), but just realized t...
I have on my desk an STM32F407 Discovery board and an STM32U083 Nucleo board. My intent is to write software for the F407 to bootload the U083 via I2C. As far as I can tell, these are the general steps:Drive BOOT0 high and pulse the NRST pin on the...
Hello, I have a custom board wich is based on the evspin32g4-dual Board. I generated the code with motorcontrol work bench and could upload it with a j-link. I added an uart output in the startup and noticed that it kept printing it, so the board was...
