Hi, I have a custom STM32F446 board. On this board I have an microSD slot that is connected through SDIO (PC8,PC9,PC10,PC11,PC12 and PD2 pins)In order to write on the microSD i follow this instructions https://community.st.com/t5/stm32-mcus/how-to-c...
Hi there,Wondering if there's any documentation or data out there for the CMTI rating and isolation barrier capacitance of the B-STLINK-ISOL. May have some pretty decent dv/dt between the computer and STM32 - want to make sure I don't inadvertently d...
Hello.I have purchased MB1166-A03 AT1 of STM32H747-DISC0.https://github.com/STMicroelectronics/STM32CubeH7/tree/1c84713102f8509deb79ae14db8dbb104c17c45e/Projects/STM32H747I-DISCO/ExamplesI have looked atIn the Projects/STM32H747I-DISCO/Examples/LCD_D...
Hello, dear community!Currently, I am working on a project with the STEVAL-FCU001V1 board that has an STM32F401CC microcontroller and an LSM6DSL 3D accelerometer and gyroscope sensors integrated chip, the board datasheet says that it is accessible th...
Hello,I am trying to measure the current consumption the PCB board which has been designed and producted by my own R&D team. But the discovery card named STLink-V3PWR is not doing it properly. There is no way for me to apply more than 500 mA, besides...
Hi STM, I really need your help. I have been trying non stop for the past 5 days just to display something on the LCD.Step1: I am able to BLINK LD2, LD3 on the board. Step2: I want to display something on the LCD. But seems like it is always black. I...
It was working fine yesterday, today I cannot connect to the board. It is enumerated/identified but stm32cubeprogrammer connect fails. I tried different modes without luck. Now I am also trying with external debugger (jlink) (board powered by USB cha...
I would like to ask about the VAPP specifications.Until now, the connection was made via JTAG as shown below.There was no problem in writing.VAPPTMS_SWDIOTCK_SWCLKNRSTGNDCan I replace VAPP with VDD (pin 19) and feed power from ST-LINK?If I do, should...
Hi, I was using brand new Stlink V3 Set to program custom device with H7 onboard for 4-5 months. The programmer was connected with 3 lines: GND, SWCLK, SWDIO, and was working fine.Today, after weekend, I wanted to test new code. I had programmer conn...
As per datasheet of stm32u5 series during the Stop 1 mode DMA and peripherals are accessible. When tried to access the GPIO read. Controller during debug mode reading the GPIO, but in the run mode the GPIO is not getting read. How to read GPIO pin in...
