FM/AM Radio firmware for the Attaky Radio series

Attaky home  ·  Discord

This repository is a fork of TEF6686_ESP32 by PE5PVB, ported by Attaky from upstream v2.20 to run on the Attaky Radio series. Modified by Attaky in 2026 to add the ATK_COMBO_V1 target, a touchscreen tuning UI, on-screen battery level, and Attaky hardware bring-up fixes. Inherits the project's GPL-3.0 license.

Compatible devices

Full-band FM and AM reception with a large touchscreen tuner. Runs on the Attaky Radio series:

• Attaky Core + FM/AM Radio module — the receiver front end (NXP TEF668x tuner), with speaker and 3.5 mm headphone output
• 2.0-inch 320×240 touchscreen — tune by frequency, step through the band, store favourite stations
• (optional) battery module to go portable

Reception features (FM/AM, RDS, memory channels, signal readouts, Wi-Fi extras) come from upstream TEF6686_ESP32.

What this fork adds on top of TEF6686_ESP32

• ATK_COMBO_V1 build target — for the Core + FM/AM Radio module hardware
• Touchscreen tuning UI — capacitive touch on the 320×240 display
• On-screen battery level
• Attaky default theme and branding
• Bring-up fixes for the Attaky hardware (sleep / backlight blackout, interrupt-pin conflicts, touch I²C pins)

Upstream reception, RDS, memory-channel and FM-DX features are unchanged.

Build & flash

This is an Arduino project — clone this repository (not upstream PE5PVB/TEF6686_ESP32) to get the ATK_COMBO_V1 target.

1. Clone this fork:

   git clone https://github.com/Attaky-Module/TEF6686_ESP32.git

2. Set up the Arduino / ESP32 toolchain per the upstream install guide.
3. Enable the Attaky target — uncomment #define ATK_COMBO_V1 1 in: TEF6686_ESP32-2.20/TEF6686_ESP32.ino, TEF6686_ESP32-2.20/src/TEF6686.cpp, TEF6686_ESP32-2.20/src/Tuner_Interface.cpp and TEF6686_ESP32-2.20/src/gui.h.
4. Replace Touch.cpp and User_Setup.h in your TFT_eSPI library folder with the copies in TFT_espi/.
5. Build and flash to the device.
