Hello,I am using STM32H7 as SPI slave with DMA transfer, the communication works fine till 18MHz of clock frequency from the master side however for higher clock speeds of 20 MHz - 31MHz it is noted that the bit shifts by 1 bit for the whole stream o...
Hi, Since there's a huge market for microcontrollers on boards such as the Arduino, like the ATMega and ATTiny, which are available in 20- or 40-pin DIPs, I was wondering if ST competes (could be with the 32bit or 8bit line) with those somehow. If so...
Hello，I want to use the PB6 pin as an external interrupt input. When the PB6 pin is triggered, the program enters the low-power stop mode from the normal operation mode. When it is triggered again, the program enters the normal operation mode from th...
Hi STM Community,I am using a custom board based on the STM32F407VGT6 MCU. Currently, I’m not getting accurate RTC time when using the internal LSI clock (the drift is too high for my application). So I’ve decided to use an external 32.768 kHz crysta...
In my STM32G431CBU6 implementation, COMP1, COMP2 and COMP3 are configured for back-EMF zero-crossing detection with TIM1 CH5 serving as the blanking source. Both rising and falling edge interrupts are enabled on the comparators. TIM1 channels 1...
Hai. Currently we are working in a project, for that we require AEC Q-100 Products. In that we need STM32F405VGT6 in Automotive Grade. AEC Q-100
This is driving me crazy, whay timers on STM32 are so complicated and no normal information / datasheets etc, how to use.Timer2 is working (external clock), Timer interrupt (TIM_IT_UPDATE) also working, but not capture interrupt. And signal is also p...
Hi everyone,I’m setting up LVGL on a custom PCB using an STM32H747BIT MCU. The display is connected via LVDS, and I’m using DMA2D for transferring the framebuffer to the screen.The issue I’m facing is that the DMA2D transfer complete callback is neve...
Moved from this thread. What is the maximum amount of time required after bringing nRST high for a Pattern 11 MCU to determine that flash is blank, recognize that BOOT0 is high, and enter the ROM bootloader? I suspect we may have a timing issue, in ...
Hi All,I am successfully programming and debugging a NUCLEO-STM32F401RE by its embedded ST-LINK programmer using STM32CubeIDE v.1.12.0 on a computer running Ubuntu 22.04.3 LTS, updated and upgraded.I have a second PC running exactly the same Ubuntu, ...
