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)?
