I have been trying to use the FatFS file system to create a new file on the SD card, or to read a simple txt file on the SD card. However, I seem to be running into issues after mounting the SD card. Initially, I ran code to:- mount sd card in main- ...
I'm trying to run a few of Zephyr's BLE examples on the B_U585I_IOT02A development board. I have tried the beacon, peripheral, and peripheral_csc examples. These BLE examples all work properly on a Nordic nRF52840 dev board.Zephyr's blinky exampl...
HI,I am using a STM32F446RE which is the 64pin package.AN4760 states that "LQFP64 supports only Bank1 and Single-SPI/Dual-SPI only"Does this mean that I am unable to use the QSPI on this chip to be memory mapped?When configuring the chip in CubeMX, Q...
Good morning,I'm trying to develop a simple Hello World printf example by writting "Hello World" into the port0 of ITM. There are several tutorials telling that 0xE000EDFCU is the base address to set the bit TRCENA to 1. However, when I try to debug ...
I am trying to use the cryptographic hash processor on the STM32h723xx, however, I cannot find the registers like HASH_CR defined in the device header files.Can someone please advise If I should be using the register definition from another MCU devic...
I want to use STM32F407V in USB device MSC mode. The device has battery to run the MCU. To fetch data from device, it will be connected to LAPTOP by USB cable.Please confirm below configuration for schematic1) Connect PA9 to VBUS on USB connector, p...
Hello,I'm working with the nucleo_h563zi board and Zephyr (3.6). I'm trying to build using MCU Boot and firmware update. I have been able to successfully build MCUBoot and flash it to the device. That boots but fails with the "Unable to find bootab...
Have you encountered issues with HAL_UART_Transmit after updating to F4 1.28.0 software packages on the F411 Black Pill, while HAL_UART_Receive_IT functions normally?
Hello,I have a custom board with a STM32L010C6 MCU, which periodically reads 3 bytes (24 bit array) from an external component through SPI.I only need SCLK and MISO since the frame resets using a timeout.I configured the SPI as Only-Receiving Master,...
Hello.The MCU currently in use is STM32L031G6X.In order to minimize current during sleep, the external circuit currently uses 100K pull-down to PB3 to set it to "Rising Interrupt" and UART 1 for testing.When measuring the current, remove the external...
