My BRAT was starting to ■■■■ me off by not doing what it was supposed to, so I decided to play with the Basic Atom Pro and ABB. I opened the baggy it came in and gently and slowly pulled it out of the foam stuff it came in. I was about to plug it into the Bot Board’s 28pin socket when I noticed the Basic Atom Pro was wider than the socket! It is about 3mm wider than the center of the place the pins are supposed to go into. Is this normal? Am I supposed to bend the pins in before I insert it? Or is this some sort of factory error?
Also, two side questions. Where is Pin 1? Is it to the Left of the little u thing at the top of one of the sides? And second question: What is a safe way to take out the Basic Atom Pro from the socket without bending any of the pins. I have a pins problem and I tend to bend pins… After a few times of bending a small tiny pin, they generally fall of and I don’t want that to happen.
hmmmm…generally the basic atom and atom pro are the same size, no?? I tried to determine the size by brining up the images of each from LM.com and cascading the windows. They do look the same size, though i was just eyeballing it. The atom pro looks even smaller. Im geussing that basic micro cut the board too big unintentionally, however it could be actually the way it is. Im not sure, you know me. I havent even gotten my micro yet
Nick said on AIM before that I was making a big deal out of it and I should just bend the pins in slightly so it fits.
Now I am having trouble getting it to talk with IDE. How do you set the baudrate on the ABB? Also, when you turn it on are the 3 LEDs supposed to turn on? (I have the 3 jumpers connected to enable the leds and push buttons.)
Uhhhh, guess you can’t. It uses 115.2kbps for programming… I tried to use auto detect to detect the Basic Atom Pro but it says none found. I used a multimeter and measured the voltage between vss and vdd and it came up with nothing… So I then measured the voltage between the vss and vdd socket areas from under the board and I got 5v which is the correct output of my battery pack. This can’t be because the pins were bent, can it? I mean doesnt both parts of the socket hole have the electricity running through it?
I’ve been IMing robo, guys.
We’ve tested the micro’s power with an LED and a resistor across it’s Vdd and Vss pins.
It glows, so it’s not a problem of the dip socket not making proper contact.
Methinks it might be a problem with the serial connection, but that’ll have to wait for a snack break.
I just had him further check hardware by measuring resistances between the micro’s pins and bottom of board.
All are quite low, which means we’ve got good connections.
He checked for continuity between micro RS232 pins and DB9 ouput cable, and he got the beeps.
Also tried setting port in Device Manager to default to 115200/8/n/1/n with the FIFO’s off (it’s needed off for my PIC programmer, so I thought we’d give it a try).
I figured all that was needed to make the micro fit was bend in each side equal amounts to make it fit. In the photos provided, it looked like there was a significant size difference but the micro was leaning to one side, which is going to give the illusion of a greater offset. If the micro was perfectly centered over the socket, you would notice each side would only need to bent in just a very small amount to fit in.
