Symptom: STM32H7S78-DK board includes a 32MB PSRAM (APS256XXN-OBR-BG() connected to HEXASPI. Somehow only the first 4MB is accessable. How to reproduce the error: Use the template project provided in "STM32Cube_FW_H7RS_V1.1.0\Projects\STM32H7S78-DK...
Hi I am developing a board with two MCU on it (stm32h755), and I am going to programme these two controllers from the same connector using only two lines (SWDIO SWCLK), I have connected same CLOCK line to both MCUs directly, and the SWDIO to a switch...
Hello Community,I'm using an STM32G474RE MCU with FDCAN0 to set up CANopen communication for a sensor node device. The setup is designed to cascade multiple sensor devices on the same CAN bus, each with a unique node ID, so they can transmit data ind...
Hi,We want to use the Type C connector with STM32 as "STM32 USB2.0 host conversion for USB Type-C platforms" for 5V, 500mA application. We have got one application circuit in STM32 application circuit. (Fig 11)Introduction to USB Type-C® Power Delive...
I am attempting to talk to BMP280 over SPI using Nucelo-F401RE. I am using SPI2 on the F401RE board to do so, I am able to read from it correctly but I can't seem to write to it in order to communicate with it. My code is as follows /* USER CODE B...
Hi. I'm trying to use STM32H573IIKxQ's SPI using HAL.I've noticed that the HAL library disables the SPI after each transfer which causes the SCK pin to go high and goes low again before the next transfer, which causes an extra bit being shifted to th...
Hi All,I was experimenting with the inbuilt temperature sensor on STM32F4 DISCOVERY board. The sensor is connected to ADC1_IN16 (16th channel of ADC1).I wrote a basic C program (attached below) and was able to get the sensor working perfectly fine.(I...
Hello ST Team,Board Series: stm32f072rbt6 Discovery. Peripheral used: SPI and DMA.SPI mode: Full duplex slave.DMA mode: CircularMaster clock: 500khzByte transfer between Master and SPI slave: 63bytesClock polarity and phase: Issue:We are transferring...
Hi, I am integrating the STM32H7S7L8H6H in a custom board. In the reference manual I found two settings which I am looking for clarification for: 1) SBS_PMCR has a AXISRAM_WS bit to enable a single wait state for the AXISRAM. I do not have ECC enab...
Hello guys, I am working on project to update the STM32G070 over the air. So basically I receive the binary on ESP32 and then forward the binary over UART to the STM32. I have used pattern 11 to enter the USART Bootloader of the STM32. Then sending t...
