is it possible to use "Pickit" serial analyzer to debug stm32 microcontroller ? i am stuck in this. need help.
It depends that what do you mean by debugging. If you mean using JTAG to debug the microcontroller, the Pickit doesn't support that. But you can use other protocols to analyze the microcontroller. For example, you can send what you want to monitor using one of the supported protocols and analyze it using Pickit and its software.
According to official website, currently these protocols are supported:
