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 ...
Hello everyone!That works:int main(void) { ... init_SPI1(); for(;;) SPI1_Send(); }And that doesn't:void TIM2_IRQHandler(void) { SPI1_Send(); TIM2->SR &= ~TIM_SR_UIF; // reset UIF bit in the status register of the timer }Why?Thank you ve...
HelloIs there a book about Cortex M7 like Yiu J. The Definitive Guide to ARM Cortex M3 and Cortex M4 Processors ?
