Hi everyone,I design the BLE (bluetooth low energy) part of my software, for that, I use BlueNRG-1, BlueNRG-2 DK SW package, provided by ST.I included the library (.a) and others source code files (.c) and headers (.h) in my project.But I feel someth...
STM32H745I-DISCO Arduino Connector Ports Non-Usable
We are using the STM32H745I-DISCO and built a daughter board that uses the Arduino Connector and ports on that connector. Unfortunately, we discovered that at least two of the ports (SDA/D14 on Pin 9 and SCL/D15 on Pin 10 of CN2), are being used by ...
COM LED remains red after download of file
Hi, recently I have had a overcurrent issue with my old stm32 Nucleo H7a3zi-q board, so I replaced it with a spare identical to the previous board, but now I am having two new issue.One is that when I connect the reset pin to an external trigger with...
