Has anyone written any device and driver support for the VMIC 4514
board?
If not, has anyone any suggestions on a good driver to use as a
template? It has 16 analog inputs and 16 analog outputs. The inputs can
be set to scan, in which case all the I/O values are always available
in registers. However, if you perform the reads on request you have to
set the read up, wait some time (~5 milliseconds) and then poll - it is
a bit nasty since there is no interrupt on ADC completion.
