Curve Tracer with Raspberry Pico

Here a preview of the curve tacer with Rp2040. it works with an IL9341 tft-display. Next to the Rapid_Development board for the Pico I use the constant-currentsource with HC595 and the new Power board for driving Uce. It works with 12v, powered from a 18650 lion-cell. The Power board includes an 12 bit ADC MCP3204, a Dual-DAC MCP4822 and an "power"-amplifier (TCA0372).. You can measure with it "normal" bipolar transitors ((n/p), diodes (and zener < 12V) .J-Fets and Mosfets.

the hardware is nearly ready, I have to test the program andthe surface.

In the next days I will present th new Power-Board for changing Uce.
