[STM32F0] How to generate PWM with DMA
Hello, I'm working with CubeMX to configure my MCU (STM32F030CCT6TR) for my school project. I want to generate a PWM with DMA but I don't know how to do it even after doing researches.Currently I configure my DMA as attached. Can you help me ?Best re...
How to flash the original demonstration back on to the stm32h747i-eval?
After working with the examples I would like to flash the original firmware back to the stm32h7-eval board. From what I can tell it looks like the touchgfx and menulauncher examples get loaded on the sd card and a program gets flashed to the mcu to ...
Resolved! I want to use DMA for UART receive. How do I generate an interrupt using the HAL for idle line? The UART Callbacks are disabled in the HAL when you use DMA. And it does not look like there is a call back for idle_line in the HAL.
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 ...
problem with STM32F411CEUx and HAL on SDIO and ADC.
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...
Resolved! Is there an updated eeprom emulation example for STM32F10x and CubeMX generated projects using HAL?
I've gone through AN2594 and the associated examples. They're all for the standard peripheral library which is now deprecated.Someone has an example of a port on github that looks reasonably complete https://github.com/lamik/EEPROM-emulation-STM32F1...
Nucleo STM32F091 skips startup script to 'LoopForever'
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...
How can I detect the active flash bank on stm32g4? BFB2 bit is not conclusive
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 ...
Availability of STM32F303
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...
Resolved! STM32H743 FMC with ST7789 doesn't work without delay
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...
