Can we simple send and receive data over Ethernet using STM32H743 without using lwip stack ?

STM32H743ZI CAN BUS Does Not Work

I have two STM32H743ZI NUCLEO Boards and I'm trying to communicate through Can Bus protocol in classic mode. In the H7 example projects, there is not an Can example for STM32H743ZI but I tried to adapt example of STM32H743I-EVAL FDCAN project but I c...

MDIO access network switch

Hello,I hope someone will have an idea for the following:I use marvell switch mv88e6071 with stm32h7.The switch works with MDIO, clause 22.I managed to read switch identifies (0x715) when using phy address 0x18.But the switch expects to read switch i...

Why LL SPI Receive DMA request generate clocks?

I use a ADS7056 temperature sensor. I want to read the temperature via SPI and DMA.To do this, I have to set the CS low, generate 18 clocks, set the CS high again. Unfortunately I haven't found a configuration that works with the LL drivers yet.To ge...

STM32CubeF3 BSP: No (Keil uV) project files?

Hi.I want my STM32303E-EVAL to I2C-communicate with the onboard ANT7-M24LR-A simply to monitor the I2C-traffic (I will check out my I2C monitoring tool). It seems to be a good idea to use the BSP driver. The BSP-file stm32303e_eval_eeprom.c contains ...

What is meant by Exported Constants ? As in, GPIO_LL_Exported_Constants

Again, trying to find out what is meant ... I saw the letters "EC" and found what it stood for and now wondering why.For example I saw idefgroup GPIO_LL_EC_PIN PIN and tracked down,GPIO_LL_Exported_Constants#define LL_GPIO_PIN_0           GPIO_BSRR_B...

USB OTG device / host switching using USB 'ID' pin - example ?

I'm looking for an example showing how switching is done between 'host' and 'device' mode using the USB 'ID' pin.The only 'dual role' example I have found requires the user to switch manually between these 2 roles (using joystick on eval board).The U...

How to I update a running RTC time and date on stm32L4

I understand that the registers are write protected and you have a clock synchronization issue, but I can not find the cube HAL level calls to do this.

Problems with DFU bootloader for STM32G431

I want to program my STM32G431-Board with the DFU bootloader. I’ve already set the configuration to get into the boot-mode with the boot0-Pin. And I explicit configure the read out protection (RDPto level 0.Also I can connect the device with the USB ...

STM32F412x - Stack overflow detection and prevention method

Hi,I'm using STM32F412 module with freeRTOS (CMSIS_V2) middleware in STCube IDE.Can I achieve below functionality as a stack overflow feature using STM32 MPU (Memory Protection Unit)?1. Detect corruption of a function return address before the functi...
