In this video, we build the hardware for the J1850 VPW development kit an STM32C0-based interface that lets you communicate with older GM vehicles over the J1850 VPW bus directly from your PC. We walk through the circuit and assembly, then test it with our custom STM32 firmware and Windows app (BridgePro).
