CFAL1602C-PYT Timing

[Lance Doyle]

We are using the CFAL1602C-PYT. What are the time requirements from power on until enable can be true and SPI transmissions can be started. Due power constraints, the display will be powered off most of the time. SPI signal will be buffered by a 2-supply level translator so the signals will NOT be driving the display when power is off.

The display will need to be re-initialized every time it is turned on. Our demo code includes our recommended initialization sequence, which includes a 500mS delay to wait for VDD stabilization before sending any commands.

The datasheet for the controller used in the display is available here: https://www.crystalfontz.com/controllers/Winstar Display/WS0010/
