sx126x_driver

Portable driver for Semtech SX126x series

Supported chips: SX1261, SX1262, SX1268.

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 SX126x::ProcessIrqs(). Everything is thread-safe.

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