Dear Sir,I have interfaced SDHC card 32GB of Sandisk with STM32L452RET6 microcontroller SDMMC1 peripheral in mode - SD 4 bit wide bus. In my device SD card as a Datalogger.Issue - When my device is working mean data is logging (Data writing in SD car...
I saw on NUCLEO-U5A5 schematics - there is a level shifter for signal T_VCP_TX:a bit obvious: if MCU jumper is set to run on 1V8 VDD - an external UART receiver (e.g. CP2102N) would not get anymore correct UART_TX signals (yes, it does not anymore wi...
Hello,which interfaces does a virgin STM32C0 in SO8N offer on the first boot for programming? AN2606 says USART1 and I2C1. In other cases, AN2606 adds a note when SWD does not work, but no such note is there for STM32C0. So, I assume SWD is supported...
I'm using an STM32H745 and have developed the Boot code, which works as expected when built as part of an application. However, having converted the Boot code to a static library and linked it into the same application the Boot startup section .isr_...
Hello,I'm writing a Flash HAL driver in order to understand better how this CHIP work.My functions at the moment work correctly but for some page I have an HardFault(During erase).For example I can't erase/write the page 0 and others pages.Please cou...
Hi Everyone,I am currently using STM32F103 for making a usb hid which acts as both, a keyboard and a gamepad.Please take a look at the descriptor and code below.Both of these work properly when used individually but when I combine them both and add r...
we are using EXTI1 interrupt in our project based on stm32f446. But the Interrupt handler is not firing.We looked into the interrupt enable registers, Mask registers, etc and all seems fine and a timer interrupt also in the project, which is triggeri...
Hi all,I'm using application note AN4636 for LC sensor.I tested with the example source code, and they work well for one sensor.But when I use multiple sensors, I face an issue. If I use the same value for inductor and capacitor for each sensor, the ...
I am working on STM32F407ZET6 with DMA+SPI in slave mode. Trying to reset DMA Counter when NSS is high to avoid shifted data transmit.TX and RX DMA are working on Circular mode.This is my tx data typedef struct { uint8_t InputState[4]; uint8_t re...
i am sorry for creating a lot of post recently but i just can not program my microcontrollers. when ever i try to program it i get this:STMicroelectronics ST-LINK GDB server. Version 7.5.0Copyright (c) 2023, STMicroelectronics. All rights reserved. S...
