GoBus ports reading speed

18 January 2013 - 05:23 PM

I've searched the forum, but couldn't find the answer to this.
If I would to connect digital signals to all Netduino Go ports (8*10 pins), what is the speed at which Netduino Go could read all 80 ports?

Help with reading what looks like SPI but isn't

02 December 2012 - 12:22 PM


First of all sorry if the terms in the post won't be technically correct, english is not my main language, but I'll try my best.

I'm working on a project and came to a point where I need to read data from the device, and I'd like to have that data in the array so I can work with that data programmatically in Netduino to continue the project.

The device I have sends data over 3 pins: CLOCK, DATA and LOAD (it is meant to be read by OKI Semiconductor MSM6775 if it's any help). The data format is something like SPI but with one difference - the DATA is in 8 bit words but LOAD signal is every 11 words. Complete data frame consist of 4 packets of these 11 words (ends with 4th LOAD signal and then it's aprox 31,4ms gap between new data frame). So I'm looking for a way to have that data frame in an array of 352 elements (4*11*8).

And this is where I'm stuck. Is it possible to do this with Netduino? How can I trick it into reading this as SPI when Netduino works as SPI master? Is there a way to send "false" load signal every 8 bits?

Any help would be much appreciated!
