ssp lpc2138
Hi to newsgroup
I'm new to lpc21xx family .
I would like to send 5 bytes over the ssp bus with maximum speed , minimum cpu
intervention for a dds chip. As i see the fifos inside the lpc can manage that
These bytes will be sent every 150 khz inside a timer interupt.
Is it possible to have an initialisation code example, send data routine example or point me to something close to that .
I would like though not to wait for chipselect line to be asserted since i want to run a
dsp filter routine inside the interupt also so i can't wait for nothing
