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 3: https://youtu.be/5Bhnv1ktSC8 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 second config on hardware, using the Curiosity Nano Explorer. We enable I2C interrupt-driven host, add TMR for 100 ms callbacks, configure Data Streamer with proximity (uint16) frame count (uint8), generate code, flash, and verify live plots via MPLAB Data Visualizer (import .ds file). Timestamps: 00:01 - First (Polled Printf) config done → Now: Data Streamer 00:27 - Ctrl Shift P → MPLAB MCC: Launch → Select Data Streamer config 00:52 - Reuse I2C host (RB2 SDA, RB1 SCL) → Enable interrupts (unlike polled) 01:47 - Pin Grid View → Confirm I2C pins on Explorer bus 02:12 - Add TMR → Interrupt-driven, 100ms period 02:37 - LED on RF3 → No delay driver needed 03:15 - Add Data Streamer Library → Auto-adds UART 03:27 - Define variables: proximity (uint16), frame_count (uint8) 03:58 - UART: RF0 TX (locked by Data Streamer), 115200, interrupt-driven 05:02 - Debug IO: RB4 (switch) 05:28 - Generate code → Copy Data Streamer example snippet 06:11 - TODO: Confirm Timer0 → Replace I2C_Host_Tasks() with interrupt flow 06:31 - Clean & build Data Streamer config → Success 06:51 - Debug → Auto-detect Curiosity Nano 07:15 - Data Visualizer: Import .ds file from MCC/generated/data_streamer/ 07:51 - Load variables → Select COM source → 115200 baud 08:11 - Start streaming → See 0x03/0xFC frame markers 08:32 - Add COM terminal Debug IO → Live toggle visible 09:01 - Plot proximity values in real time 09:20 - Note: Manual init/update of variables in frame loop 09:40 - Next: DV Runtime config (simpler streaming!)
