UART4 and SDIO in STM32F103RCT6
Fix the stm cube, as these features do not work at the same time. I lost a lot of time and money while I figured it out

when i use stm32f429 and SDRAM(IS42S16400J-7TLI),the CKE pin turn to low level after running 20 hours, cause the machine power off,i check the SW initialization is OK, in hardware ,bettween the SDRAM and MCU,there is 33 Ω resistor
this problem can be reproduced every day,but can not find the rootcause,very thanks if someone can help this.
STM32L4 - SD card writing problem
Hi, I have custom HW on HW I`m using MCU STM32L496RTx and SD card. SD card is connected with SDIO to MCU and in FW I`m using HAL libraries - DMA+SDIO+FATFS.My aim is to periodically save datasets to SD card. I generate string with 51 characters. I ...
Resolved! Transmit data on UART without using any HAL function
Dear all,I am working on STM32F413 microcontroller. I want to transmit data on UART without using any HAL function. And I want to send data in non blocking mode means on interrupt mode not in polling mode.Can anyone help me out in this?Thanks
Why SPI3 not working on STM32H7 to acquire MEMS microphones
Hi, I'm trying to port the SMARTMIC1 package (based on STM32F446) to the STM32H743 board with the CCAO2M2 board and MEMS microphones. To acquire the audio I use 2 SPI : the SPI2 in Receive Only Master (SPI2_SCK on PD3 and SPI2_MISO on PC2) and the SP...
Resolved! unexpected GPIO behavior
Hi ST community,I am interrested in using the STM32F767-Nucleo board for SPI communication. My system is as follows. I have one STM32F767-Nucleo board which is my SPI slave and a Raspberry Pi which acts as SPI master device. The Raspi should read dat...
Resolved! HAL_SPI_Receive with LSB LSB is always read as '0'
Hello. I am trying to read ReRAM( FUJITSU: MB85AS4MT) by using HAL_SPI_Receive().But the LSB is recognized as 0 even the reply from ReRAM is returning 1 to LSB. (ex: '11111111' is recognized as '11111110', or '01010101''' is recognised '01010100...
Resolved! Programming STM32 MCU using ESP8266 over WIFI.
I want to programme STM32 MCU connected to ESP8266 using USART now i want to programme these STM32 MCU using laptop at remote place connected to internet.how can i make this possible ?
Does any STM32 support HDLC/SDLC protocol
do the USART ports be configured to support HDLC/SDLC protocol ?
STM32F107VCT6 core is locked-up after programming
There are two identical controllers with STM32F107VCT6. One of them is programmed, and another one is not. Memory protection is disabled. I haven't the original program project, and the task is to read and save program from the first controller and d...
