My code is simply :HAL_Delay(100); HAL_GPIO_TogglePin(GPIOA,GPIO_PIN_5); uint8_t buffer[] = "Hello, World!\r\n"; CDC_Transmit_FS(buffer, sizeof(buffer));But nothing...> The led is blinking.> The VCp is define via *.IOC with no error.> Comp...
I'm interfacing Nucleo-H753ZI with DAC8775EVM through SPI4. DAC8775EVM works on logic HI in range of 5V and expects the same logic from Nucleo-H753ZIbut Nucleo-H753ZI MCU itself runs at 3.6V so Logic Hi isn't read by DAC8775EVM.How to Change the logi...
Hello.I will try undestand how work plate 'B-G431B-ESC1', more precisely schema operational amplifier (on image).I have not understood, what does resistors R1, R2, R3 need on cicuit with getting current from shunt? What is the idea behind their work?...
Hi All,I use the STM32H743ZI2-NUCLEO board with JP5 on 1.8V for MCU_VDD.Running the LWIP example, the Ethernet doesn't work (It does work when running with 3.3V).Any idea how to make it work with 1.8V?Thanks,David
Hello. We are working on a project that uses STM32H747 dual-core MCU.The ST-Link firmware is updated to the latest version, so debugging is not working well.So I'm going to lower it to the version I used before, but I can't download it. The lowest av...
Hi, I am looking for STM32F446RE Schematic Diagram. Can any Help me, where to find the Schematic Diagram of STM32F446RE, I have checked the documents of ST(https://www.st.com/en/microcontrollers-microprocessors/stm32f446re.html#documentation) I did n...
When we enable the RTC feature on our controllers, we do a calibration in Production against a GPS-locked 10MHz signal. Usually, we'll use the T2 ETR to clock the 10MHz signal in and an RTC-generated 1Hz signal on one of the other T2 channels such a...
I have 5 versions of the STLINK. For the three newer versions, the VCP on STLINK-V3MODS and STLINK-V3MINI work as expected. I've been using the V3MODS and V3MINI daily for over a year. The STLINK-V3MINIE shows up as a COM port in Windows Device manag...
can some one please tell me why is the schematics the pd8 is connected to gnd?here is a picture of the schematics
