STM32 MCUs Products

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...

I want to know how to read and write data on gpio pins of STM32F103C8T6(BluePill).

I am using keil to program STM32F103C8 MCU and I have the the library files for GPIO read and write functions but it is not working. There are no errors. I am just not sure about the parameters I am passing to functions. I have attached the code and...

Hi, I am using STM32f401 DISCO board and trying to generate sine modulated PWM through MATLAB. I am getting sine modulated PWM but the issue is of frequency.
