STM32 MCUs Products

I using stm32l4 in low power mode and wants micro counts of input gpio pulses.I attached the explanation and the code.

I am designing STM32F429 to access NOR Flash S29GL01GS. Refer to RM0090 reference manual, I am using FSMC to perform asynchronous read. What is the correct value for NOR_Timing.DataSetupTime? How do I calculate it?

Below is the ST sample code. /* NOR device configuration */ NOR_Timing.AddressSetupTime = 1; NOR_Timing.AddressHoldTime = 1; NOR_Timing.DataSetupTime = 6; NOR_Timing.BusTurnAroundDuration = 0; NOR_Timing.CLKDivision = 2; NOR_Timing.DataLatency = 2; N...

STM32 with UART protocol sensors (URM07 ultrasonic sensors)

Question: What function could be used/ written to receive the data (URM07)?Currently, integrating an URM07 ultrasonic sensor on STM32f1xx, according to the datasheet the transmission, have tried the function on UART (HAL_UART_RxCpltCallback) to recei...

How can we store the bonding data in order to do the pairing again after a power off?

We are working with a SPBTLE-1S as a network module connected by a SPI port with a STM32L072 as a host. We would like to store the pairing data of several devices, close the connection and make individual connection with every devices. We would like ...

Stuck in UART_WaitOnFlagUntilTimeout

Hi,I'm trying to transmit/receive data by uart. I have a state machine that is processing incoming bytes periodically, so I use a ringbuffer and write every received byte into this buffer.void HAL_UART_RxCpltCallback(UART_HandleTypeDef *huart){  if (...

STM32F7 QSPI Flash External Flash Loader

Hello to everyone. I am currently developing a project using STM32F750N8 and W25Q128. As you can guess, the project has an LCD. So the project is too big to fit into the internal memory. That's why I need an external memory integrated programming. I ...

Problem with B-L475E-IOT01A connection to the PC.

Hi everyone, first of all, sorry for my english, and I don't know if i should post this here, so i'm sorry if not.I have a problem when i connect the B-L475E-IOT01A board to the pc. It shows me a error message: "error, not recogniced device connected...

Is there an Eagle library for the STM32H755ZIT6?

STM32L4R9-Discovery and external PSRAM

Hello,I am currently working with a STM32L4R9-Discovery board with STemWin using demonstration project.I want to use the external PSRAM as a memory for the LCD GFXMMU framebufferfrom LCDConf.c :#if defined ( __ICCARM__ ) #pragma location="FrameBuffer...
