it takes around 60m/s to update a parallel lcd in some programs, are the one wire serial lcds faster or slower when compared side by side? im looking for a solution that would be less than 8m/s to update multiple items on a two by 16 display

Hi Brand
In general, any parallel transmition line is faster than a serial one. I haven't study LCDs so deep, so i can't confirm you about their response speed.

Hello,

One way to speed this up would be to use a second microcontroller connected to the parallel display. Then connect the microcontrollers together using a UART or similar to transfer data at high speed.

thanks fotios and ben, uart, how hard would that be to set up? is there any tutorials on it

Using Flowcode the UART is controlled via the RS232 component.

Otherwise a UART is also fairly simple to control using C and there should be lots of examples available online.
