Ask questions and find answers on STM32Cube packages, including HAL, LL and middleware, and expansion software.
Dear STM32 Community, We believe that the example projects provided for the STM32Cube embedded software are a valuable resource when developing projects. We would like to better understand how developers use these examples in their workflow and e...
First post, please let me know if I've made any mistakes in asking my question.I'm trying to write a bootloader for a device using a STM32u585ZIT chip. When booting, it will read a partition table saved in flash to determine if it will boot from part...
Hi, I'm working on a project which requires USB MIDI functionality. I looked into a couple of videos where USB MIDI implementation was done on other boards, but when I try to do the same on mine it's not working. I'm using a NUCLEO board (H755ZIQ), I...
Hi, I'm using a nucleo board with stm32h755zi chip for prototyping a MIDI device. I am trying to get it working as both CDC and MIDI device via USB. I was able to achieve this using I-CUBE-USBD-Composite but there is a minor problem with the implemen...
Hello,Just wondering if anyone knows the reason for the duplicate writes to the following registers in the HAL Ethernet code please?ETH->MACCRETH->MACFCRETH->DMAOMRETH->DMABMRIn the example shown below (from HAL code) the DMA0MR register is written t...
Hey all, I'm attempting to implement the EEPROM emulation library into a pre-existing project with little success. I've added the eeprom.c file to the project as well as the header include to the main.c but even prior to implementing the code, attemp...
I want to know which Wakeup pin or Reset pin wakes up the microprocessor that enters standby mode. I have 2 wakeup pins.I am monitoring SR1 and SR2 variables with Live expression in Debug mode, but when I wake up from standby mode, the value of the v...
Hello,We have a custom board based on the STM32U5A5ZJ, and are in the process of writing a zephyr driver for the two analog comparators on the MCU. Our use-case requires the driver to support interrupts on both comparators. Looking at the reference m...
Hi, I am working with a Robomaster Development Board Type-A https://www.robomaster.com/en-US/products/components/general/development-boardFrom the picture you see on that website, I plug LiPo into the 24V Power input.I am trying to do a project in wh...
What code works for the STM32L412 device?I want to load an RTC calibration value into flash memory and retrieve it on subsequent running of the firmware. I've got the reading of specific calibration values working in a different IC, for ADC calibrati...
Hi,I'm having trouble understanding the radio IRQs on STM32WL55. According to the reference manual NVIC section, there is one interrupt line for two interrupt sources (which are ORed together) for the radio:The 3 IRQs from the Semtech module ORed tog...
