    yes

    Very good idea!

    I don’t feel like it’s cheating. Arduino user’s will NEVER make anything substantial or efficient.

    What is your setup? Is it:
    PC -> FTDI -> MAX232 -> LCD
    If so, you shouldn’t need to invert any signals. I’ve used the MAX3232 dip before and I just had to send the FTDI output to it.
    As a test, you could measure the voltages when the serial port is in idle. The TTL should be high (5.0v or 3.3v). The RS232 should be a negative voltage.
    Have you tried hooking the LCD directly to a 5.0v RS232 source, like a laptop serial port?
    One other thing to check would be Rx & Tx. Remember that they should cross at some point. I.E. the LCD Rx should get piped into the PC’s Tx. (and vice versa).

    I just ordered one of these and yes, I intend on putting pins on it and putting it on a breadboard. Hopefully the spacing works with a standard breadboard.

    No, I wasted my time thinking I’d get something.

    That was a complete waste of time. Great idea, VERY poorly planned. I guess they are still running from one server. I wasted 2.5 hours and didn’t get to view one question.

    You REALLY can’t compare microcontroller development to FPGA development. For example, just imagine trying to do some basic floating point in an FPGA. You’d either get someone’s floating point core or make your own. If you are going to use someone else’s core, you aren’t going to learn anything about hardware design. Also, no matter what anyone says, FPGAs are a lot more expensive than microcontrollers. That is a FACT!
    Don’t get me wrong, I absolutely love FPGAs and absolutely HATE the Arduino environment. I work on FPGAs everyday as a profession. I have quite a bit of experience programming microcontrollers at a low-level. However, if I want to test some chip on a common protocol, I always use an arduino to test it. The library setup is quick and easy (yet horribly inefficient). Arduinos are great for quick development and testing, but not much else.
    My conclusion is that Arduinos are great for people who have never programmed microcontrollers before. However, I think everyone who has figured out the Arduino should migrate to bigger better microcontrollers. The Arduino library really limits your knowledge of using hardware. Try using an ARM, Coldfire, or just AVR without Arduino. I guarantee you’ll learn way more! Once you learn low-level design, you’ll never want to go back!

    mws,
    Could you please give some information about your setup with this board? Was programming this board straight forward? Did you use Xilinx ISE and iMPACT? Any help would be much appreciated.

    Just swap the x and y axis when reading the sensor data.

No public wish lists :(
