NRF24L / Launchpad Example CCS

Recommended Posts

Couldn't find a simple msp430 CCS example of the NRF24L 2.4ghz so I wrote one. Requires 2 msp430g2553 launchpads and 2 NRF24L modules. Press button on 1 launchpad to toggle LED on other launchpad. Note example code assumes you know C language.

//Launchpad CCS example of NRF24L Driver. Use P1.3 Button to toggle LED on other launchpad. Hence requires 2 NRF modules & 2 launchpads

//Note example uses a fixed packet length of 5.

//GPIO Pinouts

//P2.0 = IRQ

//P2.1 = CSN

//P2.2 = CE

//P1.5 SCLK

//P1.6 MISO

//P1.7 MOSI

//P1.3 Button Launchpad Rev 1.5

//P1.0 Red LED Launchpad Rev 1.5
