Firmware Exclusive ~upd~ - Ats20

ATS_EX firmware by Goshante is a popular custom firmware for the ATS-20 and ATS-20+ DSP receivers that pushes the device's hardware limits. Key Improvements in ATS_EX Firmware

Summary

The ATS-20 hardware is capable of much more than the factory settings allow. Installing an "Exclusive" custom firmware build is highly recommended for users who want a modern interface, waterfall displays, and better SSB performance. ats20 firmware exclusive

The Process:

Required Software: Most users use AVRDUDESS (for Windows) or the Arduino IDE to flash the .hex binary file. ATS_EX firmware by Goshante is a popular custom

4. Key Features of Custom Firmware

The primary motivation for installing custom firmware is the dramatic improvement in the user experience (UX). Key features include: Identify your chip: Open the ATS20 back case

1. Identify your chip: Open the ATS20 back case. Check if you have the STM32F103C8 (Blue Pill) or the newer CKS32 clone. Exclusive firmware is usually for the genuine STM32.
2. Backup the stock firmware. Use STM32CubeProgrammer to read the existing flash. Save it as stock_backup.bin. Do not skip this.
3. Connect the pins: SWDIO to SWDIO, SWCLK to SWCLK. Do not plug in USB power. Use the programmer's 3.3V rail.
4. Erase the chip: Full chip erase (not just mass erase) to remove bootloader conflicts.
5. Load the exclusive .bin file: Set the start address to 0x8000000.
6. Verify: After flashing, disconnect the ST-Link, power via USB, and hold the encoder button to reset.

C. Expanded Frequency Coverage and Steps

Factory firmware often restricts frequency steps (e.g., jumping by 5kHz or 10kHz). Custom firmware allows for:
