Wi-fi Module Test: PASS
Posted on July 2, 2012 in Category: Blog - 0 Comments
I ran into some trouble when testing this... I guess there is always something that can go wrong. After a lot of time spent tracking this down with Agent Friday, we noticed that a module used for TX/RX to my PC (converts logic levels into RS-232 levels) requires 5 volts and not 3.3 volts, which is what I was supplying it. After we got that figured out, we discovered one of the AVR pins wasn't soldered down. It figures it had to be one of the pins that I needed for testing this. Once I got it soldered down, I realized that the test program had the TX and RX lines mixed up. Three problems solved at once.
