|
|
* This Getting started is prepared for using it with a Wemos D1 mini as a master device.
|
|
* If you want to use an Arduino, then change the line 39 "SBNetwork networkDevice(D2, D8);" to the correct pinout for an Arduino (6,7).
|
|
* To get shure, that the SBNetwork library is build for a Master-Device open the SBNetwork_config.h in the libraries folder and get shure that line 6 is not commented out.
|
|
* #define RUN_AS_MASTER
|
|
* **************************************************************
|
|
* Step 1 - Prepare your device
|
|
* Connect a nRF24L01 transmitter to a Wemos D1 mini or an Arduino Device
|
|
* WEMOS > RF24 ARDUINO > RF24 ---------------------------------------
|
|
* ------------ -------------- | GND # # VCC TOP VIEW |
|
|
* 3V3 > VCC VCC > VCC | CE # # CSN OF nRF24L01 |
|
|
* GND > GND GND > GND | SCK # # MOSI |
|
|
* D2 > CE 6 > CE | MISO # # IRQ |
|
|
* D8 > CSN 7 > CSN | |
|
|
* D7 > MOSI 11 > MOSI ---------------------------------------
|
|
* D6 > MISO 12 > MISO
|
|
* D5 > SCK 13 > SCK
|
|
*
|
|
* Step 2 - Build the sketch for the master device
|
|
* Open the file SBNetwork_config.h in the library folder ../libraries/SBNetwork/src/SBNetwork_config.h and comment out (put two // at the line start) the line 6.
|
|
* Line 6 should now look like this //#define RUN_AS_MASTER
|
|
* Connect the Wemos via USB to the PC, select the right board and COM interface in the tools menu and run the project.
|
|
* After building and loading up to the Wemos, the serial monitor should show some log data.
