IoT#32 RPTC-Q – Soldering Flat Flex to PCB: LCD Initial Power Up and Rework

In today’s video, we investigate strange I2C SDA and SCL waveforms from our ESP32 to our NHD-C160100Diz LCD with ST7528i I2C Controller. We verify the Sitronix LCD controller is not responding to our I2C commands and investigate why. When we discover the issue, we perform the repair and test; will it work?
