Hi everyone - looking for some help to get my project off the ground. My goal is to read CAN bus and/or ODBII PID data using an Adafruit ESP32 feather and a Waveshare SN65HVD230. I will upload a pic of the wiring schematic but I feel pretty confident in that, as well as the pinout from my OBDII connector. CAN high/low both measure ~2.5V with a multimeter straight off the port in my VW, and those are attached via screw terminal to the Waveshare. Waveshare has power and ground, and the OBDII pinou
