Hello,
I am sorry to post here, but I have been searching for about 5
days and have found nothing for my problem.
I am developing a project on STM32L100RC and I want to connect to
an ESP8266 Wifi Module.
However, when I connect ESP8266 Vcc Pin to STM32L100RC 3.3V, LED2
starts blinking slow and then I cannot download code to flash memory
via Keil.
I have seen on User Manual:
LD2 COM: Tricolor LED (COM) advises on the communication status
as follows:
Slow blinking Red
