SPI Burst Read/Write
Posted: Thu Sep 03, 2009 6:26 am
I understand the principals of SPI communication, I am trying to communicate to a new device.
The device setup is simple 8 bit address followed by an 8 bit command. - no problem here
The device then calls for a burst SPI read to read the data from 1 address, but there are several bytes of data.
To write to the device calls for a burst SPI write. in the same manner.
I read that burst SPI mode requires the CS/SS pin to be held low for the length of the SPI Burst, I not sure if this is correct.
Can you please explane how to do a Burst SPI Read or write. I want to load/save the data from separate variables.
