i'm trying to communicate with a Wifi module (esp8266) using STM32F103, on keil IDE. As described in the schematic : i want making my stm32 send AT command to esp8266 through usart1 (Tx1), and getting the esp response (Rx1), then display the esp resp...
Rev. 5 of RM0455 says "Reset value: 0x0000 4000" for PWR_SRDCR.However, the description "Bits 15:14 VOS[1:0]: 00: scale 3 (default)" contradicts this. And on actual hardware reset value is indeed 0x00002000.
stm32f429 Internal peripherals mmc 4.2，but present emmc 5.1。Is it a fully compatible driver?Is there a ready-made example？
Hello to everyone,I just joined the Stm32 family and I chose the STM32F373C8T6 chip to use in my projects. The reason I chose this mcu was that I used two different SPI communication components in the project I wanted to do. But since I am very new, ...
Hi,i'm trying to connect two stm32 boards ( STM32f446re-nucleo and STM32f469-disco ),my question is,is it mandatory that the two boards must work at the same clock speed ( sysclk ) ?Thank you
Hello @Martin KJELDSEN @All ALL ,Facing issue in up-gradation of new firmware in following scenarios.I am using "STM32F412CGU6" microcontroller with MPU protection.My application stores the new firmware in an external SPI flash. Firmware data recei...
I am using STM32H747I-DISCO discovery kit. I want to use I2C4 in the kit but clock is not generated in scl. I am using pin D15 as SCL and pin D14 as SDA of CN5 connector of discovery board. According to the user manual of discovery board D15 is conn...
The ui framework generate an image section of the framework, there is no way to place it to internal flash, so I must copy it to a file and transform it to ext flash.So do you know how to generate the binary file?
I'm a biginner on embedded programing and facing an I2C communication halt issue when I put HAL_I2C_Master_Seq_Transmit_IT() in HAL_GPIO_EXTI_Falling_Callback(). STM32CubeIDE: Version: 1.6.0, Build: 9614_20210223_1703 (UTC)Target board: NUCLEO-G031...
