# SiK 电台
SiK radio (opens new window) is a collection of firmware and tools for telemetry radios.
Information about using SiK Radio can be found it the PX4 User Guide: Telemetry > SiK Radio (opens new window)
The ("developer") information below explains how to build SiK firmware from source and configure it using AT commands.
# 构建说明
The SiK repository includes bootloaders and firmware for the following telemetry radios (2020-02-25):
- HopeRF HM-TRP
- HopeRF RF50-DEMO
- RFD900
- RFD900a
- RFD900p
- RFD900pe
- RFD900u
- RFD900ue
注解
The SiK repository does not currently firmware for RFD900x or RFD900ux telemetry radios. In order to update firmware on these radios (for instance, in order to support MAVLink v2.0), the following process is suggested:
- Download the appropriate firmware from the RFDesign website (opens new window).
- On a Windows PC, download and install RFD Modem Tools (opens new window).
- Use the RFD Modem Tools GUI to upload the firmware to your RFD900x or RFD900ux telemetry radio.
# 配置说明
You will need to install the required 8051 compiler, as this is not included in the default PX4 Build toolchain.
# Mac OS
Install the toolchain:
brew install sdcc
Build the image for the standard SiK Radio / 3DR Radio:
git clone https://github.com/LorenzMeier/SiK.git
cd SiK/Firmware
make install
Upload it to the radio (change the serial port name):
tools/uploader.py --port /dev/tty.usbserial-CHANGETHIS dst/radio~hm_trp.ihx
# 配置说明
The radio supports AT commands for configuration.
screen /dev/tty.usbserial-CHANGETHIS 57600 8N1
Then start command mode:
