#83020 - more info Responding to: ???'s previous message |
first off i guess i really didn't specify what exactly i wanted.
as far as our team goes, we've been DESIGNING (heh theoretically) how we are going to use this chip as the core of our design. None of us have any knowledge of it, and we are all 5th year computer engineering students. We just received all of the parts approximately 2 weeks ago or so, and we've finally been able to connect to the board today (since atmel decided to give us the NEWEST version of FLIP, as opposed to the obsolete one on the CD that came with the board,heh) as far as what i was confused by on the chip is that these require a startup file? i've noticed in some of the demos given with atmel, as well as the examples in keil; that they have a STARTUP.a51 file. i'm not really sure what that is used for or how the 8051 uses it, or if i need something like that at all. These files are also in assembly, when i plan on writing all of the code in C (i am familiar with assembly from Motorola). right now the situation i'm in, or what i'd like to accomplish in the next week or so is to just get something to output on the LED. I already have all the schematics for the board, so i know what pins are going where, and i have all of the data sheets so i am somehwat familiar with the chip itself. Right now we have an evaluation version of keil, and I am able to compile .hex files from that geared towards the AT89C51SND family. We will probably be purchasing the student version of keil later in the term. We also have flip, and right now i'm just getting the hang of loading files on the chip and what not. I'm not really sure what the ISP stuff does, or what it's for (In System Programming?). All i know is that it seems like i have to turn it off, load the program through flip, then execute it, then reset the board, then every thing seems to go from what i loaded. So does the ISP toggle just call the reset (or boot up?) vector from the chip? what i'm mainly concerned with is what this board/chip are going to require to just get going. Like i said, i'd really like to just write something that goes to the LCD screen already connected to the board. I know what pins i have connected to it, I know how to load the program on the chip, it's just things like that STARTUP.a51 that are confusing me. so far thanks for the suggestions n' keep 'em coming :).
