I have a Adafruit PN532 connected over UART to the orange Pi Zero on UART1(p8/10) i added the uart overlays to armbianEnv.txt and edited the libnfc.conf to include device.connstring = "pn532_uart:/dev/ttyS1" #device.connstring = "pn532_uart:/dev/ttyS1:9600". I commented included a fixed lower baudrate to test if it might have been the problem. To thest the theory i connected a arduino due to the same serial port to print somting to see if there was any communication but nothing went through the python code i used was simple :
import serial
ser = serial.Serial('/dev/ttyS1')
print(ser.name)
ser.write(b'hello')
ser.close()
the Arduino scethch just had a
Serial1.begin(115200)
Serial.begin(9600)
// Serial1.begin(9600)
and in the loop
while(Serial1.available > 0)
{
Serial.print(Serial1.read();
}
I am coming from a Arduino background and the pi is very new to me so any advice will be greatly apprichiated
