Unitrode/Benchmarq/TI bq2050 "gas gauge" eval bd s/w for DOS

Greetings:



Does anyone have the DOS software to talk to the bq2050 eval board (model ev2050) which uses a PC serial port for communication?



The software was originally available on Benchmarq's website as 'ev2050.zip'; searching the web and ftp spaces on TI comes up null (likewise for global web and ftp searches). The eval board uses RTS and CTS to bit-bang the comm interface and the DOS software generates power for the driver IC by toggling DTR and TxD for the pos. and neg. rails respectively.



The software is described as menu-driven and permits access to all programming and status on the bq2050.



The chip's serial interface is not 1-wire, I2C or SMBus but a unique 333 bps serial protocol on a single bi- directional line; in laptop battery monitoring, it seems that this is often handled by the kbd controller and low-level bios routines. Is anyone aware of an API (BIOS, DOS, *nix, win32, etc)?

The communication is described in the Data Sheet. All though not very well. Have you tried emailing TI?

Indeed, that's where I started... I had just hoped to find that DOS software to avoid a coding chore of some magnitude on the PC platform.

No, I would appreciate any insight regarding the likelihood of success using that channel for a discontinued product (ev2050) and any pointers to internal addresses or personnel for better chances.

I am not sure who to contact. I will see if I can find you a copy. I assume you have the EV2050 board. The program will not work without it. They have a newer USB one. It does HDQ, but I am not sure about DQ.

That's great! How may I get it? E-mail attachments work or I can open up 'incoming' on our ftp server; please let me know your preference.

Thanks so very much.
