The new revision of errata sheet for STM32H7 mentions a new error relative to SPI: It is particularly vague.What "fast software" and "slow SPI" frequency means exactly ? What is the minimum ration between both frequencies to avoid the issue ?What "ad...
I'm trying to use the LCD screen in STM32N6570DK, but it has an error like this`Break at address "0x18003a1a" with no debug information available, or outside of program code.`. But when I tried to view the vector table generated by disassembly, It wi...
Hi, I'm trying to implement read ADC1 value triggered with TIM6 then write it via DMA(GPDMA1 CH0). I created CubeMx project and generate code accordingly (Using LL driver). But I can't enabled DMA channel. Is there any code example about it?
I am trying to calibrate 512Hz RTC to 1ppm or <1ppm. Desired Frequency = 512HzAverage Frequency Obtained is = 512.0073HzWhat should be the value of CALP and CALM ??? (I used the CALP = 0 and CALM = 15, but still the ppm that I obtained is ~14) Could...
Hi, I want to generate a bipolar square wave with a pulse width of 100us per phase using the DAC in STM32F446RET6. But when I measured the DAC output (PA4), I found that the DAC output was not an ideal square wave, but a trapezoidal shape w...

Hello everyone,I’m working on an STM32F7 project where I’m trying to establish USB communication between my STM32F746 Discovery board and a PC. I am really new at this really first time. I have configured the board for USB_OTG_FS in STM32CubeMX, and ...
Hello at everyone,I setup on CUBE Ide on STM32C011 mcu without the configurator TIMER1 and I would to manage it on update interrupt, but I have not the stm32c0xx_it.c file that would contain the irqHandler routines.In this case, how the compiler iden...
Hello all,I’m working with an STM32 microcontroller (specifically the STM32H743), and I have a question regarding the use of an external TCXO as the HSE clock source.As per the datasheet, when using an external clock source (such as a TCXO), the HSE ...
My question is that stm32g0b1cct6 have fdcan2 or not because i getting confuse i read many document and reference some are said that stm32g0b1cct6 is low budget mcu and its have only fdcan1 not fdcan2 . so dear support team plz response fast regard V...
