Control STM32F Using GPIO on CW308

Embedded Security ChipWhisperer Software

Hi, I connect the CW1173 ChipWhisperer-Lite through the CW308 UFO to control the STM32F303. Is there any example to kwow how to program the target using GPIO not SimpleSerial?

The reason for this implementation is to control directly using GPIO in future applications. I want to learn how to use the Scope API from the documentation at Scope API — ChipWhisperer 5.7.0 documentation. Specifically, I’m interested in the actual behavior using STM32F303’s GPIO1 and GPIO2 as UART Tx/Rx.

Is this approach feasible? Thanks!

Hello @ZTDong

You have the programmer source code in hardware/naeusb/programmer_stm32fserial.py
you can take a look and see if there is the code you need for your purposes, I’m trying to take it as a template to implement my own programmer :smiley:

For the api there is no shortcut you need to do all the notebooks to get familiar with it…
