Facing issue while flashing code in STM32H745 Disco board?

Hi , I am trying to flash my code of GPIO toggle into the STM32H745 Disco board,but it is giving the error .While building the project I have seen an error "GPIO_CM4\GPIO_CM4.sct(7): error: L6235E: More than one section matches selector - cannot all...

difference between HAL_I2C_Mem_Write() and HAL_I2C_Mem_Write_DMA()

Posted on July 03, 2016 at 10:49Hello,I generated the code using the STM32CubeMx.I'm trying to I2C communication between STM32F4(master) and IC(slave, 7bit address).I tested to two functions for I2C communication.HAL_I2C_Mem_Write is OK, but HAL_I2C...

What is your standpoint on the matter of people parsing your reference manuals to generate header files and stuff? Is it completely forbidden, do you require special license notices or are people free to use them to their liking to generate headers?

The question pertains to maximum rise time specification for STM32L151CC OSC32_IN when Low-speed external user clock is generated from an external source.

The question pertains to maximum rise time specification for STM32L151CC OSC32_IN when Low-speed external user clock is generated from an external source. This specification, according to the datasheet, is 10 nano seconds. This seems unreasonably fas...

STM32H753AI Recommended Footprint

Hello,In the STM32H753AI datasheet, there are footprint guidelines for all the packages, except for the UFBGA169 (see attached image).Has anyone built a board with this package? Where did you find any info on this type of package?Is there a database ...

I2C Library for PCA9685 won't work

I'm creating an I2C library for PCA8596 to control servos using STM32F4 Discovery as master. I already checked the PCA using arduino, and it worked. It also compiled well and can be uploaded.The problem is the SCL and SDA from the stm didn't generate...

Regarding Auto grade Controller in stm32h7 series

Hello everyone, I want to work on STM32 series of controller which supports 480MHZ or above clock rate and Auto grade temperature range(I.e Grade0: -40degc to 150degc (or) Grade1:-40degc to 125degc).We found STM32H7 series which supports our applica...

Phantom external interrupt issue with STM32F469AI (custom board)

I am witnessing interrupts on EXTI9_5 line which have absolutely no electrical stimulus. I'm seeing this behavior consistently on multiple chips so this isn't a one-off.The GPIO in question (ONE_WIRE_PIN) is PA8.GPIO initialization here:mIRQConfig.Pi...
