STM32 trying to get uasart to transmit

Hello, I wanted to upgrade my simple blinky program with the usart 2, so that it sends a simple 'B' over the serial port to my PC. I am using a Nucleo-F334R8. In the datasheet it says usart2 is connected with the USB port.Here is my code, that is not...

In 'L07x DS, please add footnote to PB5 explaining remapping to TIM3_CH2

In the 'L053 DS, DS10152 Rev 9 , pin PB5 is marked as TIM22_CH2 both in Table 15. STM32L053x6/8 pin definitions and Table 17. Alternate function port B . However, this is an exceptional pin which can be remapped to TIM3_CH2. The DS in both tables sho...

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...
