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...

I have my own F411 PCB board, on which there are a few devices that MCU/F411 uses I2C1 (I2C HAL) to communicate.Sometimes I2C HAL API (HAL_I2C_Mem_Read, HAL_I2C_Master_Transmit, HAL_I2C_Master_Receive) calls may return with error: most of the time er...
Dear, I have a STM32F446 connect trough QSPI the S25FL064L .I ask if there is the possibility using STLINK and STM32CubeProgrammer to program the S25FL064L .Tell me if there are other solutions to program the external memory trought the STM32F446 by ...
Hi, I'm making a board on which I want to use the STDC14 connector of the STlink V3 programmer for the SWO interface of my MCU.But I have some questions about the pinout, in the manual I find this table:1 - PIN 3 (T_VCC): this pin must be connected t...
