DMA memory to SPI is not working
I can get HAL_SPI_Transmit (and HAL_SPI_Transmit_IT) to work properly, but I cannot get HAL_SPI_Transmit_DMA to output signals. Here's my simplified code.

Resolved! TSC Advice please
Hi, I am working on an IR remote using STM32L412RBT6P. I have the touch sensing system working to provide the buttons for the user. The user touches a button to send an IR (RC5) code and an LED flashes to let you know it happened. Q1:I have one touch...
stm32h7 uart IDLE
Hi,MCU - STM32h743I have a use case where I need to receive a large chunk of data on UART, and the RX data length is unknown. I have read ST articles about how to do this using the IDLE feature with circular DMA (HAL_UARTEx_ReceiveToIdle_DMA). Howeve...
How to trigger fault procedure inside High-Resolution Timer (HRTIM) within program code?
Hi all!I have NUCLEO H743ZI board, and I am playing with HRTIM.I am trying to take advantage of fault logic, found in HRTIM module. HRTIM can have GPIO hardware input, which can shut down all HRTIM outputs, without ANY software overhead. Now, I would...
Resolved! STM32F7 RS485 DE Enable Not working
Hi I have been trying to configure the RS485 and trying to enable DE line. Though I have configured the DE line correctly, but still when HAL_UART_Transmit() is called, it just stays low and never get enabled for D to tranmit the data to the destinat...
STM32L4A6 consuming 2 mA system current in Stop 2 mode configuration
Hello developers,We are currently developing a low power metering product using STM32L4A6 controller. It is clocked by HSE (16 MHz) and LSE (32 KHz) for RTC and LCD. It has a magnetic and optical sensor which will be always active and generating int...
Resolved! Has STM32G0b0K system DFU bootloader or not?
STM32G0B0 datasheet DS13565 Rev 3 in Chapter 3.6 Boot modes tells: "• USB on pins PA11/PA12 (except for STM32G0B0KE)" This reads like DFU system bootloader is not available. However AN2606 Rev 64 has no restrictions for DFU bootloader on STM32G0B0. I...

Hi,I'm using stm32f072rbt6 mcu for my project.And I want to write data to my usb flash drive as a txt file.I have researched some tutorials but to do this usually used mcu's such as stm32f767zit6 and these mcu's have USB_OTG_FS feature which my mcu d...
How to find DMA channel for Timer
We are working on STM32C071KBU6 In STM example TIM_DMA, I see it uses PA10 - TIM1_CH3 with DMA channel 5, but I could not find anything about this. Anyone know how to find this information? I would like to use different pins but don't know what DMA c...
Reading actual TIM repetition count after manually stopping counter
Hi,I am using an STM32H7 TIM8 unit to generate a PWM signal with a fixed number of pulses. The TIM unit is configured in one-shot mode and the repetition counter is configured to generate the desired number of pulses, after which the timer automatic...
