The signals were figured out using a PicoScope 2206B running at 20 MS/s, ±5 V, 8-bit, 1:10, DC. All measures of digital signals were referenced by the square GND pad at the bottom left corner.
The signals were figured out using a PicoScope 2206B running at least at 2 MS/s, ±5 V, 8-bit, 1:10, DC. All measures of digital signals were referenced by the square GND pad at the bottom left corner.
