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.
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...
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...
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...
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...
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...
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...
