i connected st link to my stm32 on customboard , 1 pin -> 3.3V, 7 pin -> SWDIO, 9 pin -> SWCLK, 15 pin-> NRST, 19 pin -> GND. but keil doesn't recognize mcu. I attach the image of the connection . st link was damaged or wrong pin configuration? thank...
Hi. I have been using MCU STM32F407ZET6.But I don't know how to connect PDR_ON pin exactly.Nowadays there are some errors about this chip on board.I saw your document named AN4488.But I still don't know how to make a schematic about PDR_ON pin.Could ...
They have given male connecting headers, I need the extension connecting headers to connect with other modules using the communication protocols.

Has V-step H743ZI, 480 MHz, ST-LINK/V3, single board, ie no break-offhttps://www.st.com/en/evaluation-tools/nucleo-h743zi.html
As I know, Virtual COM port of ST-Link connection is connected to Usart2 on a STM32F401Re. When, ST-Link part is still attached everything is working fine on Usart2.However, after cutting ST-Link part of the PCB, I am trying to connect a USB-TTL conv...
I have a new problem for flash extra QSPI flash chip MT25QL512 in STM32H745I-Disco board with IAR v8.11. When debug, the following is the information:Sun Jun 16, 2019 20:24:50: Flash download warning: 327424 out of 327424 bytes from data record CODE...
I'am so happy to test STM32H745I-Disco board with STLink. But it can not find STLink in IAR V8.40. So, Jlink port connect to CN5 (STLink port for STM32F723) for STM32H745 debugging. I think CN5 is for STM32H745 Jlink, because silkscreen is the same a...
I want the ADC of the MCU be more accurate.I know the PLL belong to the power field of the VDDA .Thanks.
I am looking for pin to pin compatible chipset from both STM32H7 & STM32L4 series.As per my comparison the STM32H743ZI - LQFP144 and STM32L4R5/R7ZI - LQFP144 finds pin to pin compatible. please suggest your feedback
