Resolved! STM32H7 FMC - SDRAM byte and bit swapping

HiI am working on a project with an STM32H743 and a 32-bit SDRAMThe FMC signals are quite randomly scattered across the package and this makes layout quite convoluted and difficult. I'd like to swap byte-lanes and individual bits within each byte, fo...

Resolved! does stm32f103c6tx support external loopback?

I wrote a code for this microcontroller to test the CAN protocol, and it worked successfully in loopback test mode—data was transmitted and received correctly without using any external CAN transceiver. Then, I switched the CAN mode from loopback to ...

TIM13 and TIM14 PWM output issues STM32H562

Hi All,I have a project that is using the STM32H562. I am having an issue using tim13 and tim14 to generate PWM outputs going to LEDs. The project uses timers tim2, tim3, tim4, tim13, and tim14 for a range of different PWM peripherals. For all of the...

STM32F407 I2S2 and I2S3 not syncronized

Hi, I have an STM32F407-DISC1 connected to an Raspberry PI via I2S. The clock frequency is about 3MHz. The STM is receiving as slave on I2S2 and feeding data to a ring buffer. When the ring buffer is half full transmission on I2S3 is started (as slav...

Resolved! CAN normal mode is not working in STM32H563

Hi,   I first worked with CAN with STM32H563 with normal mode. It worked. Later Again I tried it is not working with same code. Loop back mode is working fine. I would like to use other pins for CAN since I am using PD0 and PD1. May I know which pins...

MCU does not come up after short power-cycle

Hi, we are evaluating STM32L4A6VGT6TR, with our new product prototype. We are only suppling one 3.3V to the MCU as it requires. We have already included discharge circuit, and we can see this 3.3V rail will be completely discharged within 0.288s. How...
