Heyho,I just made an interesting observation on the STM32H735 Discovery concerning the internal core power supply.I'm working on an ethernet bootloader for my custom board using an STM32H733, which has no internal SMPS, only the LDO.As I do not yet h...
Hi folks,I use MX to generate a code for STM32L4. I noticed, when I configure timer in one pulse mode, I cannot set OC CH1 in PWM mode with CubeMX. I could set it manually after code was generated, but it would be overwritten if I run MX one more tim...
Hello everyone!I'm trying to communicate with a slave device (ICM-42688-P: https://invensense.tdk.com/wp-content/uploads/2020/04/ds-000347_icm-42688-p-datasheet.pdf), but I don't recieve anything on the MISO line. I'm using the nucleo-wb55rg for the ...
In my device based on STM32U535, I use the internal RTC with LSE with external 32.768KHz crystal as the clock source. The VBat pin is powered with an external rechargeable battery. The charging is done externally, and the internal VBat charger is not...
Hello, I am trying to use the STMicroelectronics classic USB device middleware to implement a CDC class in the STM32U575 microcontroller. I am currently working on NUCLEO-u575ZI-Q. At first, I followed the tutorial on "How to use STMicroelectronics c...
Hello everyone,as I am developing keyboard with extra keys adding to the existing key board. I am adding extra modifier keys to the key board to perform the task. kindly let me know will it work and give suggestion inputs. my customized keyboard cons...
Hello, Sometimes I have my stm32F7 going in hardfault_handler, so for my customers I have to display on a screen the last address where the software crashed, then I can analyse which problem occure the crash. So I want to get the value "pc" (program ...
While using memory mapped mode for APS6408L using STM32u585 on B-U585I-IOT02A, how is the row boundary crossing handled?* If I want to write across multiple Rows in memory mapped mode, do I need to handle this manually or is it automatically handled ...
I've been using an STM32G474xx in a project for a few years now and have a function that jumps to the bootloader. It seems in a recent rev of the chip the bootloader has changed. I'm finding that I can no longer jump to the bootloader similar to how ...
In my project I use FDCAN1 and FDCAN2 for communication.At startup of the system CAN1 ist used to send out messages with 500 kBit - CAN2 is used to receive data at 1 MBit and this works. Now the user can reconfigure the CAN busses e.g. as follows:Rec...
