RF_HACK

(EN)

A platform for testing wireless transmission and radio interfaces

Currently supports:

• Sub-GHz CC1101 TI transceiver
• GPS module GY-NEO-6M-V2
• 2.4GHz NRF24L01+ (under implementation)

Interaction with the software takes place through the ILI9341 display + xpt2046 touchscreen + encoder or CLI interface

Performs:

• reception with GPS coordinates display;
• transmission and reception in the Sub-GHz range of the test string;
• range scanning mode with spectrum output on the display

Платформа для тестирования беспроводной передачи и радиоинтерфейсов

На текущий момент поддерживает:

• Sub-GHz приёмопередатчик СС1101 TI
• GPS модуль GY-NEO-6M-V2
• 2.4 ГГц nrf24l01+ (в процессе реализации)

Взаимодействие с ПО происходит через дисплей ILI9341 + тачскрин xpt2046 + энкодер мли CLI.

Осуществляет:

• прием и отображение GPS-координат;
• передачу и прием в Sub-GHz диапазоне тестовой строки;
• режим сканирования диапазона с выводом спектра

Частоту шины APB1 (SPI2) снизил в четыре раза, иначе были проблемы с мощностью передачи CC1101 (частота обмена с CC1101 не более 10 Mhz) (TODO: установить предделитель боадрейта в настройках SPI)
