Hi Chris,
It all depends on what you want to display on the display, and how quickly.
For a number of reasons, I decided to write directly to the screen buffers on
the 7390, and created functions for fonts, lines, etc and called on the
internal blit/block functions when appropriate to speed things up. I use two
screen buffers - the current display and the background screen which is being
written to, and swap them as needed. I use the unused screens to hold a number
of pages of icons which I can use the blit functions to quickly copy onto the
working screen buffer.
In my application the 7390 is communicating with a servo drive controller via
UDP and processing data that the drive sends it in a timely manor... A previous
system (using the 7300) sampled up to four quadrature encoder input, and
performed analysis of the data with the results being displayed on the LCD.
I was hoping to pull my functions together and post them on the group, but
workload (which has kept me from the group other than moderating) has not
allowed me to do so.
Regards,
PJE
