justin, they weren't. i was about connect them to their respective pins on the atmega chip. Also, I re-compiled it to 56000 just to make sure im not messing with anything. Still not getting anything -Jim *also, not seeing anything on PD0

justin, whoops, was i supposed to wire PDO to the RX from the serial chip? and the same with Tx? -Jim

Justin, I just ran a check to see if my serial port is working, and it does. I did a simple read and write from labview by shorting the pins on the cable and it worked. Hmm... the code labview used had a rate of 9600. I edited the code in AVR studio, and built the new .hex file but nothing. I'm wonedering, should i be connecting any of the serial ports ( the tx or rx) to the main chip? Right now there is no wiring on my board other than my modified 6 to 10 pin adapter. -Jim

Justin, So i tried the test 2. I programmed the chip, connected the serial cable, and ran labview. I wasn't receiving anything in the inbox. Should I have taken any other steps other than simply programming, plugging, and hitting go? Also, i took a shot at the third test. My scope showed the squarewave (with some overshoot, that shouln't be a problem should it?) but i wasn't able to manipulate it with labview. Perhaps there is a problem with the serial? -Jim * Also, after going through some of my system settings, i noticed that the bits/s on the com1 port can't be set to 56000 like you have in the code/labview. Its currently set at 9600, and the closest to 56000 is 57600.... could that be an issue?

Justin, So I've come to realize after opening up the computer that was given to us by the company who made our Radar, that the serial port on the back isn't actually connected to anything! So, do you think it would be possible to get a serial to USB cable and use that for the board? Would there be some issues with the program or would it still work okay. -Jim * I definately broke some fingers btw edit: i dug deeper and pulled out the motherboard... Got the serial port. NVM crisis adverted. The guys who put the computer together just decided to not connect the serial port on the back of the case to the one deep in the box.

justin, someone is being sneaky and snaggin my stuff. I gotta head up to the EE dept tomorrow afternnon when they're around and see if they grabbed my serial cable, and my scope. Supposing part 2 works out, after that i should set up the PWM run? -Jim

justin, it seems to be working, going on from 0 to 5.05V, Using a voltmeter though, the oscilloscope is MIA . -Jim

justin, Ya, i was pretty excited to see all of the ...OK! responses from AVR after all of the ...FAILED! and red/orange blinking lights lol. So, should i just take out the oscilloscope and check the pins to see if they are sending V signals on and off? -Jim

Justin, I'm trying to set up the programmer, but i keep getting an error STK500II, there seems to be a short circuit on the ISP connector, MOSI and SCK lines seemed to be short circuited. Should i just keep going at it and trying to fix the wiring, or is this a common error? *** Whoops, swtiched some wires, now it's blinking orange.. * ha, this will become an hourly update... Fixed it.. no more blinky orange. * Ugh, can't read the flash from the chip in AVR? The led is solid orange. * Okay, got the progammer to work. Reads and Writes the flash memory just fine (had to fix the ISP freq, and it worked.) So... now what do i do? lol. -Jim

Justin, Sound great, actually... Saturday will be a huge work day for me (working on the design project all day) so i'll probably ask you a question or two... lol. I'm a Mech. Engineer major at The Catholic University of America in D.C. and next year I'll be doing my Masters at the Naval Postgraduate School in Astronautical Engineering . -jim * Over at NPS, they use simulink instead of LabView.. , I'll have to try and persuade them otherwise.

Justin, I attached a wiring diagram and a flow chart, does this make sense to you? I don't have specs for the splitter I'm going to use, but i will shortly. It's pretty rough, but just wanted to give you an idea of how I'm setting this up. -Jim * also saw in your profile that you go to UofW ... lol, had to put something in to cite you

Justin, Thanks so much! I'm back home for the weekend, and I have an interview out in California Monday, but as soon as i get to my lab at school on Tuesday I'll work through all of this. . Just a quick question, i remembered having a problem connecting the 6 pin programmer to the 10 pin slot on the dev board. Is there simple way to wire this together? Thanks again! I'll post some videos as soon as I get everything running -Jim

Justin, No worries... im not in a rush at the moment. One thing i noticed was, the programmer has a 2x3 pin interface and the proto board has a 5x2 pin interface. So I'm thining i may have made a mistake? -Jim

Justin, Got my chips and programmer in the mail today . going to go download the software onto my computer now, just curious tho, how should i start wiring thigns together? -Jim

Justin, My group bought 2 Futaba servos (model S3306). They didn't really bother to mention that we needed to use servos until after they bought it :thumbdown: ... lol, do you think it will be okay to use? -Jim
