Resolved! STM32H7 FDCAN configured in CAN2.0 is not working
Hi guys i have a nucleo h7A3Zi-q dev board . i am trying to receive CAN messges sent from ESP32 borads . esp is sending can frame by using SN65HVD232D. and i configured the FDCAN to receive the can messages . esp can is set at 500 kbits , and my stm...
Resolved! STM32L4R9 OCTOSPI / HyperRAM support and errata clarification
Hi everyone,I’m currently trying to bring up an external RAM (HyperRAM over the HyperBus protocol) on the STM32L4R9I-EVAL board. While going through the documentation, I’m finding that information related to OCTOSPI and HyperBus on this family is qui...
Resolved! STM32F4 with DCMI
Hello, we have device with very old TFT display which is dying. New one is unable to obtain. It has similar interface as DCMI: vsync, hsync, pixclk, D0-D8.I have connected these clock/data lines to DCMI port, but interrupts was not triggered.Here are...

Can't connect to STM32C011 after setting SWD and SWCLK as ADC.
As the subject says. I am not able to connect and re-program or debug my STM32C011 ICs after I set up SWCLK and SWDATA as ADC on my firmware.NRST pin is connected and it still doen't workI know this is expected behaviour, but I should be able to re-p...
Resolved! GPIO output pulse stability (bis)
Hello,Trying to do precise GPIO pulses with assembly code - on any STM Nucleo board - shows jitter and fluctuating frequency. I was told by a super user to do it via PWMI would like to add some comment that may be interesting for others :- trying to ...
Resolved! GPIO output pulse stability
Hello,I'm using the STM32H723 (at 550MHz) to generate pulses on a GPIO output at a certain frequency (around 4KHz)I'm generating the pulses with assembly code. I've stopped systick and interrupts. However, looking at the signal with a scope, I'm disc...
STM32 FMC SDRAM bus width 8/16/32 bit
Hello, I want to add a SDRAM chip to my board. Processing the images with internal RAM is insuficient. Reading the manual for FMC part I'm not sure how the bandwidth is working. If I have a chip with 8/16/32 bit, is pretty clear: one chip and that's ...
