Hi.
I'm trying to connect a MIDI USB keyboard to Arduino Nano via USB-UART converter with ft232rl chip.
My converter is here:

but the pins are similar to this one:
My idea is to connect ICSP pins with the pins on converter (it has GND, CTS, VCC, TX0, RX1, DTR pins)
wiring: GND (Nano) - GND (converter)
5v - VCC
MOSI - RX1
MISO - TX0
DTR, CTS are unconnected.
My keyboard is powered up, but I can't figure out how to receive data applying this method.
I also tried simple connection with D0(RX) and D1 (TX) pins on arduino, but it doesn't work either.
Is it even possible to connect external device (in this case, USB-UART converter) to Arduino Nano? I found some information that in order to establish serial communication with these devices Arduino needs Serial1 function. Should I consider switching to Arduino Pro Micro for this reason?
My debugging code is here:
int ledPin=13;
void setup() {
pinMode(ledPin, OUTPUT);
Serial.begin(31250);
}
void loop() {
if (Serial.available() != 0) {
digitalWrite(ledPin, HIGH);
delay(1000);
digitalWrite(ledPin, LOW);
delay(1000);
digitalWrite(ledPin, HIGH);
}
