Hi,I use a STM32L052 and I would like to use DAC as VREF for comparator 2 (PB6) but without connecting DAC1 to PA4. It is possible ?Because under STMCubeMX, when I set DAC as VREF for COMP2, it set automatically PA4 as DAC_OUT1 but in my application,...
Hello,What is the meaning of RTC for the STM32L431 when supplied with Vbat?Does it mean that the RTC time continues to increase when Vbat is present and VDD=0V?Table 5 of the datasheet permits to hope it ....Best regardsMich

Hi everyone:cherry_blossom:I start in learning LIN bus and I wrote a basic example contain master task and slave task in STM32f103 and communicate with one slave (stm32f429), the problem in stm32f1 MCU in that the DMA read just once! so the first fra...
I'm having trouble understanding this from the datasheet and reference.What peripherals are allowable targets for DMA1 memory-to-peripheral transfers?Thanks, Best Regards, DavePS: I tried to use a stream in DMA1 to write to a DMA control register, an...
Hi Team,Am working with STM32L4R9 Discovery board,In this SOC, PMOD interface is configured to UART in defaultWhen am trying to use this a SPI interface, am facing issueCan you pls share me the sample pin configuration for PMOD connection to configur...
Hello.I try timer 2 on STM32F427 and I have a problem. It ticks too quick.Here is my system clock. I have external crystal: 25MHzClock I want to: 168MHzvoid SystemClock_Config(void) { uint32_t i; LL_FLASH_SetLatency(LL_FLASH_LATENCY_5); if...
Many of the "older MCUs" like STM32F4xx had an FSMC. I've been thinking about switching to the newer STM32F7xx and have bought a Discovery board for STM32F7508, but there are no references to FSMC in the documentation. Apparently F765/7/8/9 have a "F...
I'm working with the STM32F446 microcontroller and I'm using UART with DMA. The size of my UART packets is contained in the 3rd and the 4th packet bytes and I would like to use FIFO on the receive stream to increase the likelihood for successfully re...
