When I setup the UART i activated both DMA TX and RX, and I turned on the UART Interrupt in the MX program. Looking at the code in stm32f4xx_hal_uart.h Around line 680/* Callbacks Register/UnRegister functions ***********************************/#if ...
Hello everyone, first of all I apologize for my English as I am not fluent in it.I am using the STM32F411 and SE and when using two DMAs for Tx and Tx it always shows BUSY in HalState. This I have solved (although not totally yet) by choosing only on...
I've been attempting to debug a test application compiled for an stm32f091RC controller on its corresponding nucleo development board. To debug, I use st-util and arm-none-eabi-gdb. When I load the elf file through gdb, the stm correctly halts just a...
Hi,I am developing an application with stm32g4 using the dual bank feature for firmware upgrades. To check if an upgrade was successful, I need to check the currently active bank.I can read the option bytes and get the BFB2 bit. But: if the firmware ...
Can we expect shortage issue to go away in the near future. Both JLCPCB and Digikey have been having stock issues for months. I'm unable to get the MCU I've designed my project around (F303C[B/C]Tx). Digikey only has the lower flash mem options avail...
I have an STM32H743 connected to a screen that uses ST7789 via FMC (i.e. parallel connection) using 8-bit bandwidth and A18 to select between command and data.The current code has an issue that the screen output is messed up (see pictures below) if I...
Hi ST member,I was shocked on how little information ST providing for GAP_OBSERVER_ROLE, Nordic supplier provide more information if compared to ST. So for I only found this info https://www.st.com/resource/en/user_manual/dm00162667-the-bluenrgms-blu...
I am working on STM32H753 microcontroller. I want to receive string using UART interrupt and send the same string back on UART. The IDE is keil uvision 5. The problem I am facing is that when I first program the MCU UART is working fine and I am rece...
When I increase the value of FOSR and IOSR,Iam not getting the proper values output from the dfsdm filter it keeps varying and is not also proper HAL_DFSDM_FILTERREGULARSTARTDMA(&hdfsdm1_filter0) How to keep the values of FOSR and IOSR?
Hi guys, I'm starting from a bare STM32G070KB, and cannot for the life of me get it to connect.I had this problem with an STM32G071CB but was able to solve it. The problem I was having was that I couldn't get an ST-Link to read the chip on a breadboa...
