will reboot automatically with the brand-new firmware active. 5. Troubleshooting Common Firmware Issues
avrdude -c usbasp -p m328p -U flash:r:backup.hex
A high-quality USB-C or Mini-USB cable (ensure it handles data transfer, not just charging).
Ensure you are using the correct COM port and baud rate (115200). ats20 firmware
The (often based on the open-source work of Ricardo Caratti and later modified by others) bridges this gap by utilizing the full processing power of the onboard Arduino/Atmega328p chip. Key Features of Enhanced ATS20 Firmware
The (often called the ATS-20+ ) is a portable all-band radio based on the Si4732/Si4735 chip and an Arduino-compatible microcontroller. Updating the firmware is a popular way to add features like SSB (Single Side Band) support, RDS, and better battery monitoring. Preparation & Required Tools Before starting, ensure you have the following:
Options to turn the display off to save power, and adjustment of the CPU frequency to reduce interference. Menu System: An advanced, easier-to-navigate settings menu. Pre-requisites for Firmware Installation will reboot automatically with the brand-new firmware active
Disconnect any antennas and remove the housing screws if necessary to identify your internal board type. ATS_EX Firmware for ATS-20 DSP Receiver - GitHub
The centerpiece of the ATS-20 firmware ecosystem is the project by developer , called ATS_EX (based on PU2CLR's original work and inspired by closed-source firmware from swling.ru). This is the most feature-rich and widely used firmware available for the ATS-20 and ATS-20+.
// Pseudo-ish bfo = si4732_get_ssb_bfo(); if(rotary_delta) bfo += rotary_delta * 10; // 10 Hz steps si4732_set_ssb_bfo(bfo); update_display_bfo(bfo); Ensure you are using the correct COM port
A: Yes. Many custom firmware builds allow the ATmega328 to enter "sleep mode" when the screen backlight is off, extending runtime from 6 hours to nearly 10.
