Re: [PSUBS-MAILIST] OSS Pressure hull basic layout.
Well Warren,
Have a look at Cygnal Microcontrollers
(www.cygnal.com)and you'll see that they're coming
much closer and even better than the TI ones (smaller,
more than 10x faster, much bigger memory FLASH/RAM
,more flexible with their crosspoint matrix and all
the asynchronous port you want RS232/SPI/I2C).
Same thing with the analog Devices microconverters.
If someone is interrested, I can have some samples. I
already have all the functions for I2C and Rs232 com
available. I'll provide all the source code and the
schematic when I'll be done with the tests.
