I am trying to make a guitar loop pedal with my nucleo-l476rg board. It has 1MB of flash and I am trying to write and read from bank 2 only as it is the bank of memory I want to use for storing recorded audio. I currently have an active buffer set up...

Hi everyone,I've built a STM32H745ZIT6-based board. The microcontroller uses the LDO to generate VCORE. The idea of this board was to build a standalone solution based on my Nucleo-H745ZI-Q project.I did prepare a very simple project, where I toggle ...
I am trying to erase a sector of the flash memory on my STM32H503RB. I have successfully validated that I can write to the flash, but when I attempt to erase the sector that I wrote, the contents that I wrote stay the same. I have a feeling that I ...
Hi,MasterMCU: STM32H743IIQuestion:Both FDCAN channels in the MCU are currently in use. I now intend to reset each FDCAN instance (i.e., reset all its registers) during its respective bus-off event, and then reinitialize the instance. Resetting all ...
Hello, I have implemented a sdcard socket on my board based on the STM32F411, I use SDIO & fatfs r0.15c p2, The SDIO DMA NVIC configuration is : /* DMA2_Stream3_IRQn interrupt configuration */ HAL_NVIC_SetPriority(DMA2_Stream3_IRQn, 6, 0); HAL...
Hi,I am designing a custom PCB with an STM32H723. To programm it, i bought a brandnew ST-Link v3 MINIE. CubeIDE reads the serial number of the V3 but can not connect to the target.- Target is supplied with VCC.- From the Board-to-Board-Connector afte...
I have the following flash protections requirements:1) Write protect the last sector (with start address 0x0803F800)2) Read protect the entire flash with Level 1.3) If the read protect is lowered, the data in the last sector must be unchanged.I'm per...
DK1 interface a one lane DSI display. DSI display is using SH8601A LCD driver. SH8601A only can be initialized in LP mode, not HS mode. In Mx, DSIHOST configuration, 1. Bus Turn Around Request is enabled2. Transmission commands in LP mode is confi...
Hi All, I want to build a system to sense 240 low current signals at 20kSPS at the same time using 15 ADC with 16 channels each (DDC316 by Texas Instruments, Datasheet: https://www.ti.com/lit/ds/symlink/ddc316.pdf). I intend to use something like t...
