sd-card read write mode speed same in SD 1 bit mode and SD 4 bit mode?why
i m writing data in 1 bit mode or 4 bit both have the same speed, i m using stm32f746g discovery board. and what can be the max read write speed?

Problems with fast subsequent rising and falling callback functions
I have the STM32G030K6T.Connecting a magnet to my magnet detector causes HAL_GPIO_EXTI_Rising_Callback and removing the magnet causes HAL_GPIO_EXTI_Falling_Callback. I think I have too much code inside these functions. Inside these functions I'm fadi...

STM32L071CB SPI Driver for MX25L8035F
Dear experts,I bought a MX25V8035F chip. I try to build my own SPI driver to communicate with this chip. I use STM32L071cb, STM32CubeIDE, and HAL Libraries right now. But, the STM32L071cb always receives a random number. for example, I try to read th...
Resolved! Cortex M4 upgrade with STMG0 QFN32/48 pinout
Hi, thank you very much for the STM32G0 series, this really is very nice.Just for some applications I would need optioinally more CPU power, esepecially divide and best also floating point (so Cortex M3/M4 woudl be nice).I do NOT need higher speed / ...

Resolved! How to send and recevie data from serial print.
I'm using servo and driving it with servo motor. I want to print the servo degree via UART to serial. But im getting unknown characters. My code is;/* USER CODE BEGIN 0 */ uint32_t potadc; uint32_t servopot; /* USER CODE END 0 */ /* USER CODE BEGI...
Hi, I am new to this, and I just bought the P-NUCLEO-IOM01M1 master board , and I am trying to follow the UM2421-guide and trying to setup a connection to another device (TA2212, from Ifm), but the connection cant be established.
The control tool can correctly identify the Imported IODD-file, but when i try to setup the IO-link communication in the control-tool I recieve the COMLOST fault. Furthermore I receive an Event error with the code: 49415. The STEVAL-IOM001V1 is corre...
Resolved! Bricked After first Debug STM32H735G-DK
I bought this kit to learn but after first time debugging i can't connect to it at all.I just set some GPIO input and outputs and got a led working in debug mode and now i can't connect to the board again and the previous debug program doesn't work e...
Resolved! Configuring LPTIM to generate autoreload interrupts on STM32L4
Hi,I am trying to learn how to use the LPTIM1 of the STM32L433 Nucleo-64 board (with the CPU: STM32L433RCTxP). I want to experiment on generating an interrupt every second with the LPTIM (I usually use a TIMx peripheral for this, but was interested b...
