STM32EZ-ScopeV2 Dual channel STM32 oscilloscope

The STM32F103CBT6 microcontroller comes with dual 12 bit ADCs capable of working in parallel and sample rate up to 0.8 MSPS, which are an ideal match for a low bandwidth dual channel oscilloscope.

The analog front end is as simple as possible for the purpouse of lower noise, no post construstion adjusments and build simplicity. For that reason it has only two independently switchable gains per channel, the rest is to be done in software. Triggering is also to be accomplished in software.

Both channels should allow for a 200 kHz bandwith, with the option of interleaved single channel mode with higher bandwidth capability (HW modification required).

Display used is an 2.4" 320x240 TFT touch display module with an SDcard slot (for saving waveforms).

Software in progress...

Project is a sequel to version one, which I independently developed as a semestral project on the CTU FEE (GitLab page is in Czech language):
