Hi everybody, I have an RFID module which can be controlled through an RS232 communication. I have tested it with a rs-232 connection with a PC and with an also with an usb-serial converter. I can connect with the RFID module an receive its data through a terminal emulator such as Teraterm, PuTTY, etc. The data are simply ASCII strings of codes. The module can also be configured by sending some ASCII commands, this is also tested. Now I want to do the same with a microcontroller (Arduino, Lopy, etc.), i.e., the microcontroller would act as the PC, getting data from the RFID reader. I
I am facing problem in interfacing the PMODIA AD5933 board with ARDUINO UNO. I am using the attached Library and Program to find out the impedence, phase and frequency measurement. It is running if the start frequency is set to 1000 Hz in the program. The problem is I'm calibrating with RFB = 100K and Rcal = 100K but the impedance is coming in negative value. PMODIA AD5933 Board Connection with ArduinoUNO Board is : SDA--> A4 SCL--> A5 VCC--> 3.3V/5V GND-->GND ad5933-test.ino arduino-ad5933-master.zip
