Hi,
i'm a new user and i have a question. I buy 2 apc220 with usb support, and i follow many tutorial, but i can't comunicate between arduino and pc.
i write a simple arduino' skretch, that write number "1" on the serial; the code works because i try it with the COM1 (the same COM which i use to put the code in arduino). But when i plug the apc220 in arduino i can't comunicate.
Someone know the reason.
p.s. sorry for my english but i'm italian and this is my "english"
It would have helped if you had provided a pointer to the APC220:
Did you install the CP210 driver so your PC sees the USB-to-Seriual adapter as a serial port?
i install the drivers for the module e my os see this:
so i think everything it's ok in pc-side. I plug the module in arduino following this schema:
but without led and switch, so i just put the wireless module. Arduino' skretch is this:
void setup()
{
Serial.begin(9600);
}
void loop()
{
Serial.println("1");
delay(1000);
}
Very simple skretch. But doesn't work.
The manual (http://www.dfrobot.com/image/data/TEL0005/APC220_Manual_en.pdf) shows a connection to the Set pin (#7) set to HIGH. That connection is not in your diagram.
Did you run the ACP22X program and set up both units to the same baud rates. There are two rates. The RF rate and the Serial rate. They must match, card to card. Also that program will tell you if the PC sees the units. On my ACP220 setups the SET input is left floating and they work fine. Also, on my setup I use a Software Serial port so I can use the hardware serial port for troubleshooting messages.
When i plug the module the Arduino's Tx and Rx leds don't blink. I don't know the reason.
groundfungus can you show me a simple schema with the skretch?
