Forum Thread 2 EchoGuard – MAX32630FTHR Setup & First Blink Program Upload

Nidhee

Electric plug Hardware Setup & First Code Upload

 Connecting the Boards

image

To begin the setup:

  • The MAX32625PICO is connected to the Analog Devices MAX32630FTHR using the provided socket-to-socket connector cable
  • Both boards are then connected to the computer using USB cables (included in the kit)

 This setup allows the PICO board to act as a programmer for the main board.

Gear️ Development Environment Setup

Setting up the software environment can be a bit confusing, as most available tutorials are quite old. So here is a simple and working method.

Step 1: Install VS Code

Step 2: Install PlatformIO

image

  • Go to Extensions in VS Code
  • Search for PlatformIO IDE
  • Install it

 What is PlatformIO?
PlatformIO is an extension that makes it easy to develop, build, and upload code to embedded boards. It manages libraries, toolchains, and programming automatically.

You can see that I have already installed it.

Warning️ After installation, restart VS Code.

Step 3: Create New Project

imageimage

  • Click on the alien icon Alien (PlatformIO) on the left
  • Click New Project

Fill details:

  • Project Name: max32630_test
  • Board: Maxim MAX32630FTHR Application Platform
  • Framework: Mbed

Click Finish and wait for setup.

Step 4: Create Main Code File

image

  • Open src folder
  • Create new file → main.cpp

Paste this test code:

#include "mbed.h"

// onboard LED
DigitalOut led(LED1);

int main() {
while (true) {
led = !led;
ThisThread::sleep_for(500ms);
}
}

Warning️ Important Setup (OpenOCD)

To upload code properly, we need OpenOCD.

 Step 5: Download OpenOCD

imageimage

Make sure folder contains:

  • bin
  • drivers
  • share

Step 6: Find Target Config

Go to:

share → openocd → scripts → target

image

Find file:

  • max32630.cfg OR
  • max3263x.cfg

 Remember this name

 Step 7: Update platformio.ini

image

Add these lines:

upload_protocol = custom
upload_command = C:\openocd-20251211\OpenOCD-20251211-0.12.0\bin\openocd.exe -s C:\openocd-20251211\OpenOCD-20251211-0.12.0\share\openocd\scripts -f interface/cmsis-dap.cfg -f target/max3263x.cfg -c "program .pio/build/max32630fthr/firmware.elf verify reset exit"

debug_tool = cmsis-dap

 Save the file

Step 8: Build & Upload

image

  • Click Heavy check mark (Build) at bottom
  • Wait for “Build Success”
  • Then click → (Upload)

Warning️ Important:

  • Always Save → Build → Upload
  • Do NOT upload directly

Upload Indicator (Important Observation)

image

During the upload process:

 The MAX32625PICO board starts blinking a green LED

This indicates:

  • Code is being transferred
  • Communication between PC and main board is active

This is a useful visual confirmation that the upload process is working correctly.

After uploading:

To demonstrate this, I changed the timing to 0.5 seconds.

The onboard LED on the Analog Devices MAX32630FTHR starts blinking
 This confirms:

  • Board is working
  • Code is running
  • Setup is successful

 Next Step

In the next update, I will:

  • Connect the microphone module
  • Start reading real-time sound signals
  • Begin implementing sound-based detection 

If there is a simpler or more efficient setup method, feel free to share your suggestions.

  • nice write up - I wander if an animated gif uploads better to the platform?

    if curious, assuming you have ffmpeg installed

    # generate a pallete for good colour selection
ffmpeg -y -t 10 -i Video.mp4 -vf \
    fps=10,scale=320:-1:flags=lanczos,palettegen ~/palette.png

# generate a 7 frame per second 320 scaled animated gif 
ffmpeg -t 10 -i Video.mp4 -i ~/palette.png \
  -filter_complex "fps=7,scale=320:-1:flags=lanczos[x];[x][1:v]paletteuse" \
  MAX32630FTHR_blink.gif
