Hello there,

I have written a program with the purpose of hopefully controlling the directional flow and speed of a DC Motor from an input to be detected via a Wifly chip, which will be sent from another Wifly Chip.

The Wifly-Wifly Connections are configured however, with this program to control the Motors, some depressing results have be obtained.

Program :

#include "mbed.h" #include "Wifly.h"

Serial pc(USBTX, USBRX); Wifly wifly(p28,p27,p21, "mbed", "password", true); PwmOut Pwm(p21); DigitalOut fwd(p5); DigitalOut rev(p7);

int main() { char haha[129]; char var; rev = fwd = 0; Pwm.period(0.020); Pwm.pulsewidth(0.11);

while (1) {

if (pc.readable()) { wifly.putc(pc.getc()); printf("PC Readable\r\n"); } else { pc.printf("PC Not Readable\r\n"); }

if (wifly.readable()) {

pc.printf("Wifly Connected!\r\n");

wifly.read(haha); scanf("%s", &var);

switch (var) { case 'f': rev = 1; fwd = 0; break; wait(0.5); return(1);

case 'F': Pwm.pulsewidth(0.5); rev = 0; fwd = 1; break; wait(0.5); return(1);

case 'r': rev = 1; fwd = 0; break; wait(0.5); return(1);

case 'R': Pwm.pulsewidth(0.5); rev = 1; fwd = 0; break; wait(0.5); return(1);

default: break; printf("Invalid Input\r\n"); wait(0.5); return(1); } } else { pc.printf("Wifly Not Connected!\r\n"); break; wifly.reset(); } } }

//

The result I am picking up from Tera Term right now is simply

PC Not Connected Wifly Not Connected !

I have no idea how to continue to work on this program, especially with the PC Not Connected Feedback that this program is sending me.

May I ask why is this happening / causes for this problem ?

Thank you for your time

Hi, Did you ever resolve this issue, As I am having a similar issue with not being able to connect the PC. When ever I check if the pc.readable, I get false (0).

Thanks, Michal
