Resolved! STM32H7 dual core: FreeRTOS & Timer selection for each core
Hello, I am using STM32H7 dual core series. Currently I am planning to enable FreeRTOS in M4 core and let M7 core run in regular fashion. As FreeRTOS uses SysTick, I have given M4 core on of the controller timer. Is there any need to also give M7 cor...
Resolved! Imprecise error flag after writing to the flash
Hi experts,I'm adding to my existing code (that runs on a STM32F105) a function to store a word in the flash.I basically copied the code from the official example based on the HAL libraries, here my function:uint32_t FLASH_Write_Data(uint32_t StartPa...
Resolved! Speaker output in STM32H563ZIT6
HI,I would like to use the speaker output on the STM32H563ZIT6. I reviewed the wiki, but there aren't any references about how to play audio with the speaker output. Is it possible to enable this output to play audio?Does the STM32H563ZIT6 have built...
EXTI15_10_IRQHandler; interrupt; PE13
Might need your help to solve this issue. Thank you. Background: 1. I have a 1 Hz signal, and I'd need this signal to trigger interrupt. 2. Use GPIO as interrupt. 3. Using STM32CUBEMX to generate codes. 4. STM32F769I-EVAL board. 5. Already successful...
Measure Circuit returns wrong value after connect to G4 chip
I am using the STM32 G431RBT6 chip. There is a circuit for measuring voltage, current, and other parameters.When the circuit is not connected to the chip, the voltage divider works perfectly. However, when the circuit is connected to the chip (with t...
Can't pull up a GPIO pin set as AF QSPI I/O
Hi,I am working on a project on STM32H750. I set up the QSPI I/O pins on PD11, PD12, PD13 and PE2. Because PE2 (IO2) also serves as the WP# pin for the external flash, I would like to set it to have an internal pull-up, so the GPIO definitions are li...
Resolved! Is STM32G4 FMAC X1 vector\non-circular mode documented\supported?
I have multiply\accumulate operations that I want to streamline by using the FMAC. For my application I will be loading the X1 buffer by DMA from peripherals and I don’t want to use circular mode. Documentation mentions ‘vector mode’ which matches wh...
Resolved! How do I transfer input capture values from TIM1 to the DAC1 output via DMA?
I'm new to STM parts and toolchain and I need to send input capture values from TIM1 to the DAC output via DMA. Cube doesn't support peripheral to peripheral DMA, but its been suggested I can accomplish it with a peripheral to memory DMA transfer, tr...
Resolved! Can DMA be used to forward input capture values to periferal registers?
I need to use DMA to forward input capture values from the timers to the DAC output register. The input capture values represent the period of the input signal, which makes it work as an FM demodulator. If I can route the captured values to DACs and ...
