This project aims to develop a small handheld device capable of various functionalities related to 433MHz radio communication. The device allows for receiving, transmitting, copying, saving, and jamming signals within the 433MHz frequency range. Additionally, it features a 128x64 I2C OLED screen and six buttons, four for navigation and two for confirming and canceling actions.
To see the prototype PCB go to this repo.
To see my workflow go to this Trello board.
- I have started development from scratch to make the overall quality of the code better from what i have learned.
- 433MHz Communication: The device is designed to work within the 433MHz frequency range, enabling it to interact with a variety of radio devices operating on this frequency.
- Receiving: The device can receive signals transmitted by other 433MHz devices, allowing users to monitor and analyze the data being transmitted.
- Transmitting: Users can utilize the device to transmit signals to other 433MHz devices, facilitating the communication between the handheld device and compatible devices.
- Copying: The device offers the ability to copy received signals, allowing users to replicate and retransmit the same signal multiple times.
- Saving: Users can save received signals for later analysis or retransmission, providing a convenient storage mechanism for important or interesting data.
- Jamming: The device includes a jamming functionality, which can be used to disrupt or interfere with the signals of other nearby 433MHz devices.
This guide will get you setup your basic development enviroment, building and running is quite simple with the PlatformIO extension.
Theres only one prerequisite right now.
- PlatformIO extension for Visual Studio Code
This is the bare minimum you have to do to get the project running on bare metal.
- Clone the repo.
git clone https://github.com/Flee-Time/FreqBox.git
- Open the cloned project in VS Code with PlatformIO.
(Optional) Change the
platormio.inifile to suit your prefered upload and debug method.upload_protocol = stlink debug_tool = stlink
Build and upload under the
genericSTM32F411CE/Generalproject tasks using the PlatformIO extension.
This project utilizes a combination of hardware components to create a versatile handheld radio device.
- Hardware used in this project
STLink clone
STM32F411CEU6 BLACK PILL / WeAct Black Pill V2.0
