Hi.
I am a beginner in microcontroller programming and new on this forum also.
I have a development board EM-STM3210E with STM32F103ZET microcontroller and i try to make a simple project (turn ON a led) using Keil uVision5.
Can somebody told me how to proceed.
I am stuck in this point, in Manage Run-Time Enviroment I dont know what option i should choose.

Thank you.
