Post by thread:[PIC]: [WANTED]: I2C Open-Source Tool

[boy, I just know I'm gonna get into trouble on this one ...]. I am in need of a very basic tool for reading I2C serial EEPROMs. Preferably some source code [or even hex file] I can simply program into an 'F84/'F877/whatever that does nothing more than read the stored data and send it to a host PC via RS232. Nothing more. Probably 200 lines of free, uncumbered open-source code. ;-) Basically, all I want to do is have an "independent" check on the algorithms that I have developed for a project. In and out in 30 seconds, nothing fancy. Anyone know where I can find this? best regards, - from dan michaels [in O-S hell] ====================================== -- http://www.piclist.com hint: The PICList is archived three different ways.

I persinaly use just about all of the code in that file in a project of my own, which uses a MAX233 RS232 chip, an Atmel i2c 24C64 EEPROM, and three Phillips i2c 8bit i/o expander chips, and a Dallas i2c temperature chip. Everything works great! I'd actualy sugjest using snipp.htm as a starter template for your own software. Anyway, its good stuff, IMHO.

BTW if anyone wants to check out the project I'm working on check out: http://www.irule.net/projects/carlcd. Its on the slow side due to my lame connection, but the horrable pictures of the unit are hosted elsewhere. PIC's are mad fun stuff.

This is a very nice full-featured commercial programmer, but not quite what I was after, which was just a little "free" tool that I could download into a PIC in 2 minutes and use immediately one time. I checked the snipp.asm code on piclist.com from Tony Kubek. It is clearly professionally written code and very nice, but also not what I need. It accesses internal EEPROM rather than external, has empty RS232 routines, and there is no indication is has ever been verified independently. Basically it is a code fragment and not a "tool". I was hoping no to have to build my own tool, rather to find something working and already proven. You know, in retrospect, I wonder whether the piclist community hasn't totally gone off in the wrong direction here. Instead of offering disembodied code segments and pushing for open-source universal programmers which entail months and months of work, maybe we would be better served if we concentrated on the following: 1 - "Complete" running example programs for ALL the standard PIC controllers that would contain a good mix of the common operations - interrupts, RS232, A/D, I2C, timer fcns, command processing, etc. This would really make it easy for newbies to get into any PIC of their choice. Download a completely working source file, assemble, program and go - rather than grab a bunch of disembodied code fragments written in several different dialects. 2 - "Tools" - small, complete, and verified utility programs that perform certain targeted functions, like I2C and SPI EEPROM read/write, RS232 comms at all baud rates to test links, programs to exercise/test proto h.w., etc. These tools could be offered as both source and/or hex, and people could download them and program into a PIC and have them running in a matter of minutes. They would only need be available for about 3 cpus - '84, '873/876, '877 - covering major pinouts. They would have already been verified by others, and known to work properly. We seem to have both ends of the spectrum discussed a lot on piclist, but where is the middle ground? Maybe it's here somewhere and I haven't found it.

Beggars can't be chooses Dan. I (we) don't have the money to pay for donated code and I (we) don't always have time to write new code just for fun. I do make the time to post to the site what code I write or find that may be of use. It only take a few seconds to go to www.piclist.com/techref/microchip/routines.htm login, browse to a good page, then use the form to select "Add a [public] [link], enter a short description and "optional link to" pagename.htm (where pagename is the file name of your program. e.g. snipp.htm) then press the Add button. This creates a new page which you can now go to, and using the same form select "Add a [public] [program listing]" paste your code into the text box (leave "optional link" blank) and press the Add button. SHAZAM! new code on its own page at piclist.com with credit to you. I do anything I can to add to the available code base at piclist.com. I agree that more complete, better tested programs would be great. I just now (literally) got on my knees and I am begging you (or anyone) to expand on Tony's snipp.asm to make it a complete (and tested) program. It doesn't grow without help. --- James Newton (PICList Admin #3) spamBeGonejamesnewtonspamBeGonepiclist.com 1-619-652-0593 PIC/PICList FAQ: http://www.piclist.com or .org {Original Message removed}

You complained about the quality of code available at piclist.com, and specified what you would rather see. I explained why the code on the site is as it is and put out a plea for you and others to improve and expand it (hopefully as you had suggested). How, exactly, is that missing the point? You are correct that concentrating on basic, complete, debugged, tool like code would be ideal. I am trying to make it possible for anyone who has or takes the time to do that to share the result. Please post your improved code to the list and to the site.

But yes it's true it only 'deals' with internal eeram and does not contain routines for i2c. However I have some ( possibly ) useful routines for an full i2c master implementation with read/write pointers for internal ram. Using these an full implementation for reading/writing/verifying(against ram)/initialising(from rom table) an i2c xicor eeram. Easily modified ( i.e. crippled :) for more 'simple' eerams ). And ofcource fully interrupt driven uart routines with buffers. However these are not for the light hearted, represents some long dwellings into the data sheets and requires some chip knowledge to make sence. Written in asm, relocatable code and uses some 18xx specific opcodes. Only 'verified' by me so bugs are possible, however none known to me. Are these of interest I willing to share them. /Tony Tony Kübek, Flintab AB ²²²²²²²²²²²²²²²²²²²²²²²²²²²²²²²²²²²²²²²²²²²²²²²²²²²²²²²²²²²² "No! Try not. Do, or do not.
