Hello, I am working with an STM32G4 microcontroller and noticed an unexpected behavior regarding Bit 20 (BFB2) in the User & Read Protection Option Bytes.According to the reference manual, BFB2 is a read-only bit.After performing an option bytes eras...
I have two Nucleo boards that are connected with a CAN bus (Transceiver SN65HVD230). I would like to communicate with standard CAN, eight data bytes, data rate 50000 bit/s. For the F407 all TX & RX events are triggering (reused old working code) the ...
I'm trying to understand how the CSR register works. I though initially that the various reset reason bits are mutually exclusive. That turns out not to be the case. For example, I'm seeing SFTRSTF and PINRSTF together, and also BORRSTF with PINRSTF....
Hi,I am using nucleo-l476RG board.I am new to USB audio, I am trying to create USB Audio class (Speaker/MIC) using HAL. I am sucessfully able to create a node for speaker and MIC in my laptop. But unable to send and receive the data over USB. Can any...
I have WeAct studio's STM32h750VBT6 board. i am trying to access Sandisk's 64 GB MicroSD card (formatted as FAT32) through MicroSD card Adapter using SPI1. I am not able to access memory card. i have enable SPI1 and made enable PB1 (SD_CS) as gpio_ou...
I made a custom board using a C091KCT6. I assumed I would be able to figure out a way to display data in real time using printf. Unfortunately, I did not make provision to expose PA2 and PA3 (or indeed any pins other than the ones used by my board). ...
