Probably not. At present, I protect the sourcecode. Its my only value added... I cant afford patents...

I have an opensource version, but it doesnt use the SD card, only EEPROM..

Anyway, do you have any suggestions on debuggers I might use??

Its a datalogger.

When you push a button, it writes the gps-location to the SD card at SD-block-location=counter,
then decrements counter and writes it always to block 1 on the SD card.

Sometimes it writes all zeroes instead of lat,lon.
Sometimes the counter decrements by more than one.

but this only happens every 1000 times.
I share RAM alot. Eg, I use unions to reuse RAM, so I figured that was suspect,
but not sure which emulator to buy to set-a-breakpoint on the event...

thanks for any help.

Programming / Which programmer to buy to find nasty PIC16F877A bug
« on: May 01, 2008, 06:52:17 AM »
Hi,

I buy PIC's from modtronix, so I use the bootloader, CCS compiler and lots of printf statements!

I attached an SD card to a SBC44B which works great 99.999% of the time.

I have spent over a year trying to find that .001% bug.

Q: Any suggestions on how to find it? What to buy and why?

thanks

yea, I finally figured out what A and K mean.

A=anode= +5v
K=cathode= gnd

hey, I saw a plug for modtronix. Vote for it....

Yea, I meant the red one.
Thanks for the reply. The closest I could find is 7-215079-6 (tyco / amp) so I give up...

I think I will just grind it off and solder direct!!!!  yee haw

thanks again

I bought the LCD162B-BIW as you mentioned, but I dont know how to get the backlight to come on.

Do I have to apply additional voltages?

I noticed an "A" and "K" on the rear. Do they have to hook to T1 or something which isn't populated on the SBC44B?

Sorry I don't know anything about LCD's....
Thanks for the continued help...

I have several SBC44B dev kits and they are cool. I can't seem to get away from its cost effective functionality!

Q:  What can I buy/do/replace to make it so I can read the LCD in the dark?

(I know nothing about backlighting, etc)

For now, I have a flashlight pointing at it  :?


Am I SOL?

Thanks for any leads!

Is the Windows part of the SBC44B bootloader free?
If so, can someone give me the url so I can download it.

I am far from home, and I need it......
(didnt some guy in the netherlands write it open source??)

General / dataflash

Hey Modtronix.

Do you sell anything with tons of memory yet???

I need a SBC44B with 8MByte dataflash.
I got $200US.   Do you have any solutions????

Thanks for any leads!

Ok,
I need some closure here.
I gave up on SDCC and switched to CCS.
Mostly due to no C simulator.

I found it.
It's just a simple bug in printing NULL in lcdPutRomString.
I guess I over-reacted...
