This is a fork from **http://tmrh20.github.io/RF24** which can be build as a static library for Atmel Studio 7.
|
||
|
|
|
||
|
|
Not all files are needed.
|
||
|
|
|
||
|
|
Just copy the following structure into a GCC Static Library project in AS7:
|
||
|
|
```
|
||
|
|
utility\
|
||
|
|
ATXMega256D3\
|
||
|
|
compatibility.c
|
||
|
|
compatibility.h
|
||
|
|
gpio.cpp
|
||
|
|
gpio.h
|
||
|
|
gpio_helper.c
|
||
|
|
gpio_helper.h
|
||
|
|
includes.h
|
||
|
|
RF24_arch_config.h
|
||
|
|
spi.cpp
|
||
|
|
spi.h
|
||
|
|
nRF24L01.h
|
||
|
|
printf.h
|
||
|
|
RF24.cpp
|
||
|
|
RF24.h
|
||
|
|
RF24_config.h
|
||
|
|
```
|
||
|
|
|
||
|
|
Only ATXMega256D3 is supported right now!
|
||
|
|
|
||
|
|
## Notes
|
||
|
|
The millisecond functionality is based on the TCE0 so don't use these pins as IO.
|
||
|
|
|
||
|
|
The operating frequency of the uC is 32MHz. If else change the TCE0 registers appropriatly in function **__start_timer()** in **compatibility.c** file for your frequency.
|
||
|
|
|
||
|
|
|
||
|
|
## Usage
|
||
|
|
Add the library to your project!
|
||
|
|
In the file where the **main()** is put the following in order to update the millisecond functionality:
|
||
|
|
```
|
||
|
|
ISR(TCE0_OVF_vect)
|
||
|
|
{
|
||
|
|
update_milisec();
|
||
|
|
}
|
||
|
|
```
|
||
|
|
|
||
|
|
Declare the rf24 radio with **RF24 radio(XMEGA_PORTC_PIN3, XMEGA_SPI_PORT_C);**
|
||
|
|
|
||
|
|
First parameter is the CE pin which can be any available pin on the uC.
|
||
|
|
|
||
|
|
Second parameter is the CS which can be on port C (**XMEGA_SPI_PORT_C**) or on port D (**XMEGA_SPI_PORT_D**).
|
||
|
|
|
||
|
|
Call the **__start_timer()** to start the millisecond timer.
