STM32L4 STOP2 System abnormal restart
Environment: STM32L4 + 32.768K LSEFunction: Wake up and work once every hour, then enter stop2 mode. During the one-hour sleep, wake up every ten minutes to feed the external watchdog.Problem: The device resets directly when waking up every ten minut...
Issue when generating PWM on STM32F769
Hello Team, I am using stm32f769 controller. I am using timer 1 channel 4 for pwm output, and my APB1 clock is 180MHZ here I am taking prescaler : 17999 and ARR=1999 and ccr=1000 for this values I can see output of pwm by generating 5hz pulses. But ...
Custom STM32F469 board driving DSI LCD exhibits random horizontal shift.
I have been using a STM32F469i Disco board to interface with a 800x800 LCD in MIPI DSI video burst mode. In order for this to work from the DISCO board, I have an adapter PCB to connect from the DISCO board to the LCD.It took a while to get going, bu...
Resolved! USBPD EPR Source
Hi, I'm trying to implement USBPD EPR Source with DisplayPort Alt Mode on a STM32G071. I use the latest https://github.com/STMicroelectronics/stm32-mw-usbpd-core, which seems to support EPR, but I couldn't find any complete examples with a working EP...
Resolved! STM32F446 with TrustZone?
Isn't TrustZone something which started to be only since Cortex-M33?JW
stm32u073k8 No VLCD pin
I'm using the LCD of the STM32U073K8, but the program failed to initialize the LCD. After checking, I found that the STM32U073K8 doesn't have the VLCD pin. Is the STM32U073K8 not compatible with the LCD peripheral? Or are there other settings?
SPI constantly sending Clock and OxFF over MOSI after enabling SPI in half duplex.
Hi,I have been trying to communicate with an SPI peripheral (NOR Flash). I want to use SPI in half duplex mode. The problem is that as soon as enable the SPI peripheral I see SPI constantly sending OxFF over MOSI even though I have not written anythi...
