TIM6 Interrupt and Compiler Optimization

I have a project (for STM32L0) that use TIM6 to generate an Interrupt every 5ms and everything works perfectly both in release and debug when built wih no optimization.Then I built the same project with -Os(optimize for Size) -ffunction-section -fdat...

Can I measure PWM duty cycle using DMA?

I am on STM32F401 and I want to measure PWM duty cycle (PWM input) with timer 3 and a DMA channel. I'd like to have the DMA to do several measurements and then calculate the average over it. My configuration is like this:My DMA config is like this:My...

STM32 MODBUS

Im using nucleo stm32f103. Does a modbus library exist or how would one go on with using modbus? Could not find any tutorials online.

How to burn (download) a program into a Micro if I am not using a Experimental board as Discovery board....

Hi ST_community."Programing STM32F429ZIT6 micro"I have a question: what are the options to burn/download a program into a STM32F429?At this moment, I am working on STM32F429ZIT6-DISC1 board, now, everything is ok, everything is done it throughout ST_...

NUCLEO-L073RZ, ADC reading problem on PA2 and PA3 pins We removed SB13 and SB14 resistors on NUCLEO-L073RZ board and configured PA2 and PA3 as ADC channels (in CubeMX), but AP2 and PA3 don't read any analogy inputs.

We also configured the other PAx pins, such as PA0, PA1, PA4, PA5, ect as ADC channels. these pins work properly.Removing SB13 and SB14 is based on the suggestion of NUCLEO-L073RZ manual (UM1724 Rev 14), in order to use PA2/3 pins.Please let us know ...

Question about MCU STM32G474RET6, SPI peripheral doesnt work well in 42.5MHz or more

Hello ST Team !I would like to ask you a technical question about the STM32G474RETx controller, SPI peripheral.I'm trying to configure 2 MCU's (master & slave) as follow:- SPI1 in Full-Duplex mode, 16bit data width- Master SYSCLK: 170MHz, SPI clock: ...

Can I write to a UART Data Register if the RXNE bit is set(data has been received in the RDR but not read yet) ?

I want to use the WM8994 on the STM32F769-DISCO for 24 bit acquisition on the Line In connector. Unfortunately the BSP code is fixed at 16 bit. :-(

Has anyone done the changes necessary to switch up to 24/32 bit acquisition. It seems like its just AIF1_Control[6,5] on the WM8994 but the SAI is a complex beast and I'm not having a lot of luck. Any pointers would be greatly appreciated.
