Would a SPI mode where the AUX pin starts a spi read or write of 24 *8 bits? help others as well?
I am thinking of getting a buspirate to hammer out the ads1298 spi read and write protocol but it has a data ready pin and the aux could be used for that.
I imagine other ADC chips might be like this also.
I would suggest (as Ian said in your other topic) to write a small basic program that does this. As I assume there are too much flavors of adc and as many protocols to read it. It is too hard to get it universal and a script is fairly easy to suit to fit.
The scripting language is described here: http://dangerousprototypes.com/docs/Bus ... _reference (http://dangerousprototypes.com/docs/Bus_Pirate_BASIC_script_reference)
You can publish the program, so others could benefit from it.
A 'delay to change' command for the AUX pin might be handy none-the-less... Maybe for the next firmware version :)
