Getting Started with MCC Melody in VS Code® (for PIC16/PIC18/AVR Development) Playlist: https://youtube.com/playlist?list=PLtQdQmNK_0DTt4jZ7BQiFBV51zTt3MGqO&si=evOSLi5ww8ycAe0R Link to Part 1: https://youtu.be/rER0qkbnFpw Link to Part 2: https://youtu.be/B7h3FoFTH5s The previous videos have built up pseudo configurations for MCC Melody configurations associated with a proximity sensor example, namely: Polled Printf, Callbacks Data Streamer, Callbacks DV Run Time. In this video we build up and test the final config on hardware, using the Curiosity Nano Explorer. We enable I2C interrupt-driven host, 100 ms timer, add DV Runtime with CDC UART (TX: RF0, RX: RF1 weak pull-up), generate code, flash, and auto-discover symbols (proximity, frame count, debug IO) in MPLAB Data Visualizer. Due to the DV Run Time, we can directly find static or volatile variables in the .elf file, so no manual framing is needed. Timestamps: 00:03 - Data Streamer done → Now: DV Runtime (simpler visualization) 00:57 - Ctrl Shift P → MCC Launch → Select DV Runtime config 01:16 - Reuse I2C host (RB2 SDA, RB1 SCL) → Interrupts on 02:04 - Pin Grid: Confirm I2C on Curiosity Nano Explorer 02:31 - Add TMR1 → 100 ms, interrupt-driven 03:00 - LED: RF3 output 03:35 - Add DV Runtime → Auto-adds CDC UART 03:53 - UART: RF0 TX, RF1 RX → Enable RX weak pull-up (critical for UI commands) 04:47 - Debug IO: RB4 (switch) 05:11 - Generate code → Copy DV Runtime example snippet 05:57 - Replace main.c → Confirm Timer0 → Remove blocking wait 06:15 - Clean & build DV Runtime → Success 06:34 - Debug → Auto-detect board 06:53 - Data Visualizer DVT Setup: Start session → Pick debug/production .elf 07:15 - Tip: Match .elf timestamp or rename output (prox_sensor_DVRT.elf) 08:32 - Ctrl Shift P → MPLAB Data Visualizer → Open DVT 09:12 - Load launch.json → Start DV Runtime streaming 09:55 - Browse symbols → Auto-find proximity_value, frame_count 10:31 - Add to plot → Live read/write variables (reset frame count to 0!) 11:15 - Add Debug IO → Real-time control from PC 11:42 - DV Runtime lets you tweak timing at runtime (see user guide) 12:11 - Wrap-up: Full multi-config flow in VS Code MCC Melody
