Adding Custom boot logo on TCA/PRC152

What You’ll Need

• TCA/PRC-152A (Version 2023).

• A Windows PC or laptop.

• USB programming/data cable.

• TCA programming software.

• Your custom boot logo image (64X32px PNG format).

Step 1 – Prepare Your Boot Logo

Even though the TCA/PRC-152A’s LCD is 128 × 64 pixels, the firmware only accepts a 64 × 32 pixel logo.

To prepare the logo, open any photo editing software, such as Paint, Photoshop, or GIMP (you can also use any online editor). Create your logo at  ratio of 2:1 to be resized at 64 × 32 pixels in black on a white background. Save the file as a PNG.

Step 2 – Converting PNG to HEX

Go to https://javl.github.io/image2cpp/ and upload the PNG.

in Image Settings

• Resize canvas to 64X32.
• Background colour/ color to White.
• Scaling: Scale to fit.
• Keep rest same.

in Output

• Code output format: Plain bytes.
• Draw mode: Vertical – 1 bit per pixel.
• Leave the rest as it is.
• Click Generate code.
• Ignore the first line ( // ‘your image’, 64x32px).
• Copy the HEX code.

Step 3 – Uploading Code

• Go to Programming Software installation folder Default “C:\Program Files (x86)\TCA-152A”.
• Backup “Logo.txt” in the folder as its original HEX for Harris Logo. 
• Open “Logo.txt” and replace the HEX code with your code.

NOTE: You need to remove the Spaces after the “,” and use Uppercase HEX code i.e. replace “0x00, 0x7f,” to “0x00,0x7F,” also make it 8 bytes per line.

• Save the text file.
• Attach Programming cable to radio and PC/Laptop.
