How did you connect the Logic Analyser to the stm sir ?


#3

You can connect it to any pin as you want, just set the output high when you start and set it low when you finish, then you can measure the difference.

In the example, i connected the logic analyser to the green led output pin PG13.

Thank you Sir i have another question can you Explain why you Write GPIO_Init_PB(); and why you didn’t use the PG When you choose the PG13


#5

GPIO_Init_PB() function is used to configure the GPIO for leds, if you go inside this function you can see it uses PG13.

Sir for the Logic Analyzer you use the Channel 1 and the GND ? if i have three or four Channel how i can see it ( Visualize it ) and i have 1 GND Writed on Him GND CH1


#7

This is a common ground for all channels.
