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...
Firmware updates and flash banks on an STM32L496
Hello Forum, I have a question regarding OTA and toggling between flash banks on a STM32L496. I have read many forum posts on here relating to this and I have reached a point where I need assistance as debugging iteratively is taking a lot of time. I...
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...
