I am having an issue with my FPS (https://www.sparkfun.com/products/13007) : I can’t control it with my Arduino Pro Mini 3.3V.
I connected directly to the computer (through FTDI) to use the SDK Demo, it worked fine, but back on the Arduino, nothing at all except that on the serial monitor:
"FPS - Open
FPS - SEND: “55 AA 01 00 00 00 00 00 01 00 01 01”
Here is what I have tried so far:
- switch TX/RX (because from a website to another they are not the same…)
- input voltage 3.3V, 3.7V, 5V
- with / without resistors
- change baudrate ( 9600 / 115200)
and my code:
FPS_GT511C1R fps(1, 0);
fps.UseSerialDebug = true; // so you can see the messages in the serial debug screen
// FPS Blink LED Test
fps.SetLED(true); // turn on the LED inside the fps
fps.SetLED(false);// turn off the LED inside the fps
Any help please ?
