RXFD_MODE and TXFD_MODE pins, what are they for?
STM32H745 DS indicates there are these signals:CANFD1_TXFD_MODECANFD1_RXFD_MODECANFD2_TXFD_MODECANFD2_RXFD_MODENo mention is made in the DS for their purpose, nor in AN5348 "FDCAN peripheral on STM32 devices". The signals are not mentioned at all in...
Hello, I need help in setting up a SPI3 communication with AT45DB161E flash memory using STM32H743II. My application gets stuck when trying to write/read data to the flash and I don't know why. Details and code can be found below. Thank you!
More details on the topic:I have a working application that runs with nuttx and is able to successfully configure SPI3 and read/write to the flash memoryI have compared the registers between my app(that doesn't work) and the application that runs wit...
Resolved! How to send a single USART character under interrupt, on an STM32H743?
I have the following code, which is *almost* always working. (It typically gets stuck after 10-100K characters.)void USART3_IRQHandler(void) { if (LL_USART_IsActiveFlag_TXE(USART3)) { stats.txe++; if (LL_USART_IsEnabledIT_TXE(USART3)) { LL_US...
1.stm32l052 Smbus traffic has no ack 2.XferOptions parameter configuration
HI,1.When I was debugging mlx90615, I used smbus to communicate. The reading function was as follows:uint32_t I2C_Read_Cmd_Data (SMBUS_HandleTypeDef *hsmbus1, uint16_t chip, uint8_t *cmdBuffer, int32_t cmdBufferLen, uint8_t *dataBuffer, int32_t dataB...
STM32F407 DISC1 transmitting characters to PC via USART2 - No data seen on Tera Term.
I'm trying to transmit some characters to the PC COM port from the STM32F407DISC1 board through USART2, but no data is seen on Tera Term.The board is connected to the PC through USB connector "CN1" (mini-B type), hte same used to download the program...

Resolved! How to check Timer PWM activity?
Hi,Sometimes in my program, I use a timer in PWM mode, and sometimes it is off. How can I check the timer status, on or off? Thanks.
I am using a STM32f7 as a SPI master and STM32F0 as SPI slave. When I am Running Both MCU at 48 MHz then transmission and reception both are working well but when I am running STM32F7 at 216 MHz then its not working.
Please help me.My codeSPI Master Code----------------------Initialization/* SPI4 init function */void MX_SPI4_Init(void){ hspi4.Instance = SPI4; hspi4.Init.Mode = SPI_MODE_MASTER; hspi4.Init.Direction = SPI_DIRECTION_2LINES; hspi4.Init.DataSize = SPI...
