Interceptor

A passive digital signal sampler for the CH32V003. Tracks the levels of PC1 and PC2 and sends any changes over serial to the host. These can be converted to a VCD format file and analyzed in sigrock.

Designed for sniffing I2C traffic. PC1 and PC2 are 5 V tollerant and have pullups enabled. Tested at up to 200 kHz.
