Simple wireless serial test using a pair of Pololu Wixels. Uses m3pi as a convenient dev board, since it is prewired for a Wixel.

+// Quick test for a pair of Pololu Wixels, both configured with Wireless Serial App (download from Pololu)
+
+// m3pi Robot is used as a convenient dev board, since it has a socket for a Wixel already, and connects
+// to the Wixel on pins 28/27/26 (Tx/Rx/nReset).
+
+// Note the nReset is optional, and the code works without it (thanks to internal pullup resistors).
+// However, don't declare p26 as a Digital output unless you plan to use it as the Wixel nReset, in which case
+// you need to drive it high to bring the Wixel out of reset.
+
+m3pi m3pi;
+Serial Wixel(p28, p27); // tx, rx
+Serial PC(USBTX, USBRX);
+//DigitalOut Wixel_nReset(p26); // don't declare unless you want nReset capability
+
+int main()
+{
+ m3pi.locate(0,0);
+ m3pi.printf("Wixel!"); // need to send something to the m3pi just to stop it running the demo app...
+ //Wixel_nReset = 1; // take the Wixel out of reset
+ Wixel.baud(9600); // Wixel default baud rate (can configure other rates via Wixel config app...)
+ while(1)
+ {
+ Wixel.printf("Hello Wixel\r\n");
+ while (Wixel.readable())
