sx128x_driver

Portable SX128x driver written in C++.

Supported chips: SX1280, SX1281, SX1282. Only SX1280 is tested.

Requirements

• C++14

Features

• Easy to use
• Should work on nearly all platforms
• Multiple instances
• No macros, no global scope shit, and thus no collisions with other libs

Usage

Write your own hardware abstraction layer (HAL) class and implement the Hal* functions below:

• HalGpioRead
• HalGpioWrite
• HalSpiTransfer - This should take care of chip select signal

It's very simple. Right?

And these if you have RF switches / external RF PA (optional):

• HalPreTx - Called before a TX operation
• HalPreRx - Called before a RX operation
• HalPostTx - Called when (1) TX_DONE (2) TX_TIMEOUT (3) before a RX operation
• HalPostRx - Called when (1) RX_TIMEOUT (2) before a TX operation

Enable DIOs & process GPIO interrupts by yourself. When DIO fires, simply call SX1280::ProcessIrqs(). Everything is thread-safe.

That's all. The code is well documented. Most usages are exactly same as the SX1280 mbed driver.

Examples

sx128x_linux_driver is a good demonstration of how to use this driver in Linux.
