Resolved! (SOLVED) Sprintf with Floating Point Number enters infinitive loop in Bare-Metal Programming
The problem is about Sprintf with floating point number on STM32L452RET6P.Although all settings are correct, sprintf doesn't work with floating point number only. Although it works on stm32cubeMX, it doesn't work on bare-metal program. It loops endle...

Anyone have a working example of SDMMC working with an eMMC chip on the L476 or H743 series MCUs that they can share?
Signa A and B with 90 degree phase shift
Hello dear friends,does any one know how i can have 2 signal with 90 degree phase shift? but i want to use this easy bit pattern to have it and not pwm, just with this bit pattern 00, 01, 11, 10, and also a sleep time for delay, it shouldn't be diffi...
Resolved! Using both CAN1 & CAN2 both in STM32F446RC
Hi, I want to use both CAN1 and CAN2 for my application with 500kbps and 125kbps speeds respectively. I have initialized both of them as per my requirements using HAL. Where in Tx is implemented in polling and Rx in interrupts. CAN1 Tx and Rx working...
Resolved! STM32 CANbus is not sending/receiving message
I am trying to send messages from Can1 to Can2 in an stm32f205vet6. HAL_CAN_AddTxMessage is returning HAL_OK but I am not able to receive any messages in CAN2. And I cant see any messages transmitted in a scope. clock speed = 120MhzCan speed = 500 kb...

Resolved! ADC sampling frequency - STM32H743ZIT
Hi,I use ADC3 on STM32H7, I need to know (and set) what is sampling frequency.I use 3 channels in 16 bits. What I tried to calculate?1) Tconv_time = 8.5(setable)+8.5(fixed for 16 bits) = 17 ADC clock cycles = 17/30Mhz = 566 ns2) From this image I sho...
