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 ...
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...
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...
Isn't TrustZone something which started to be only since Cortex-M33?JW
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?
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...
I have ordered NUCLEO-G491R to test STANDBY mode power consumption. The power consumption measurements are taken via the PPK2 from Nordic.https://www.nordicsemi.com/Products/Development-hardware/Power-Profiler-Kit-2The steps:1. Take STM32CubeMX examp...
Hello, rm0456 in chapter 33.4.8. talks about "Software procedure to calibrate the ADC" and "Extended calibration mode" on some products. It is not clear, if "Software procedure to calibrate the ADC" is enough for products with "Extended calibration m...
HiI'm new to the STM32 board but not to Arduino IDE. I want to use two STM32 boards (with DXV lr30 900) for LoRa communication. I'm starting with a minimal program (without LoRa), just to see how the communication works between the STM32 and the Ardu...
Hello,I am designing a board with an STM32H755ZIT6 and want to verify whether my power architecture is safe.Power architecture:Battery inputTwo buck converters:3.3 V buck → MCU VDD5 V buck → LDO + voltage reference → VDDA and VREF+Operating case:For ...
