Newbie level 2
Hello everyone,
first of all, I'm a total beginner to microcontrollers. I'm working on my bachelor's thesis and it's a collaboration with one company which is designing and constructing audio devices. My task is to connect a peak programme meter with PC via USB to send data corresponding to audio levels. The PPM has Atmel AT89C5131 microcontroller on it. I was told that the easiest way to do the communication(because of avoiding the USB programming) is to make the USB connection act like serial RS232 connection. I found some test/sample program from atmel for AT89C5131 and an .INI file. I installed the .INI file, wrote the sample program using Flip. After that the PC was still recognizing the microcontroller as unrecognized USB device, not as a virtual COM port that i was hoping for. I also tried manually installing the COM port in Windows using Add Hardware(where pointing on the .INI file). Then in the device manager i could see a COM port called "AT89C5131 CDC USB to UART MGM" but it wasn't connected with the microcontroller whatsoever.
I'd be grateful for any help/advice on how to make this work.
