In section 19.6.2 LCD frame control register (LCD_FCR) of the STM32U0 RM0503 Reference Manual, the examples provided for PS and DIV initially count up in decimal, but finish in binary. This looks like an accident and is confusing to the reader. https...
Hi,i am using STM32G0B1KB and the UCPD peripherals to implement an USB-PD device with 2 ports:- Port 1 is DRP- Port 2 is Source onlyI need the dead battery pulldowns for port 1, so I will connect the UCPD1_DBCCx pins with the UCPD1_CCx pins as descri...
Board: NUCLEO-N657X0-QRevision: CProblem: MCU cannot pull PA2 to low, only to about 2.5V. I tried it in push-pull and open drain modes. SB6 has been desoldered to isolate it from the analog attenuation circuit, but it didn't work with it soldered. It...
Hello,I may have made a *** of myself on a prototype, and need a bit of help with a work-around. I have an external clock signal on TIM20_ETR (PG5) for some pulse counting stuff. This works.However, I intended to use the same clock signal to trigger ...
Dear all,I'm trying to generate a waveform using DAC OUT1.I configured pin PA4 as analog (works)I configured DAC1 without DMA and it worksI configured TIM6 and it works Then I configured DAC with DMA, configured DMA, but output never changes.Where ca...
Hello,I have an STM32G441 and using DMA to transmit some SPI data. All works so far. The problem is the chipselect. I am using the software chipselect. So before I start the DMA I pull CS low. Then when the DMA complete interrupt fires I pull it high...
Hi,I am facing an issue while connecting to my board using STM32CubeProgrammer and ST-LINK. I would appreciate any help.Board: NUCLEO-F072RBProgrammer: ST-LINK (Onboard)Software: STM32CubeProgrammerConnection: SWDST-LINK Firmware: V2J46M31Issue Descr...
Hi,How to set UID using CubeMX and read in STM32L476 and use it for device commissioning process?
I have a question about writing to the STM32F410's FLASH.I'm creating a program to write data received via USART to FLASH, but it's not working correctly.The writing to FLASH itself is happening, but the written data differs from what I expect.This d...
I wonder if any one can help me.The rtc Cal freq produced by the init code below produces on 490Hz. The RTC clock is loosing about 55 sec in 20 minutes.Is there a way to increase this freq without replacing the crystal? static void MX_RTC_Init(void)...
