Look at the SERIN2/SEROUT2 commands in the manual.
They allow you to specify optional flow control pins which you would connect to the RTS/CTS pins of the module you're using if it has hdw flow...
So I just disregard these pins and let them float?
CuriousOne Yesterday, 07:35PBP command SEROUT2 can handle flow control.
With that said I've never needed to use it with OpenLOG but it depends on how much data and at what speed you you're trying to log.
Well as seller stated, they only need 5V for operation, no separate negative supply needed. It also has contrast adjustment pot soldered on it.

In the text mode you can get 8 lines by 30 charactors with a 240x64 display.
Do you have a datasheet for the displays you are getting?

I've looked at these modules and besides TX/RX they also have CTS RTS pins. Can be these handled by PBP, or I have to add some manual code like this?
HIGH RTS 'make RTS pin high

For a more compact and maybe easier to code the command and data be at defined length.
So command 9 would be 09 and data 9 (this is extreme but for the sake of discussion) would be 00009.
So...
so a command is *99 or *9 or *09 [where 9 == a numeric digit]
and a parameter is 9 up to 999999
how do you signal that the command has been input and the parameter begins
i would be...
The commands following the * will not be more than 99 so * and two digits for the commands.
The parameters are max 6.
Once Melanie had posted a similar example for rs232 communication but has...
Re: Simplest way to write to USB stick or TF/SD card with PBP?
Thanks, I'm only going to write to flash drive, so I'll need SERIN for just status checking, whenever drive is physically present.
