Unicode Question
·
Am I correct in assuming that the “FullDuplexSerialPlus” object
expects to receive 16 bit characters, “Unicode” and will stumble if sent
8 bit characters old “ASCII”. I am using the rx, tx and getdec methods
·
I have a project that works great In HyperTerminal but has some problems connected to some old hardware that predates Unicode and only sends & receives 8 bit characters.
·
Has anyone dealt with this. I can eliminate the old hardware but would like to have the option of using it if modifications to the propeller object·are not a huge undertaking for a newbe to spin and assembly language.
·
I would rather not spend a lot of time beating a dead horse so to speek.
·
Anyone care to give me some advice?
Are there any good books?
·
Thank you in advance for any advice.

getdec reads a string until it sees a CR, then attempts to convert into a integer

I made an assumption that it running in assembly would eliminate the need for a buffer as it could process the input faster than the 9600 baud I am sending to it.
I must have to create a transmit sub that sends one character at a time to the propeller rather than sending strings.
Dose this sound like a solution?

even the assembler part only has 16 character buffers.
You might need to add some overhead so the propeller can tell you when it is ready to receive more input.

I shouldn’t need any back & forth communication for flow control. I may need to setup a small buffer or array at the propeller if my one character at a time sub fails me
A lot of the “FullDuplex Serial” object is in spin.
I guess I m guilty of wishful thinking.
Nothing comes easy for me
Thanks for the info

I have successfully replaced an old Step motor
Index card with the propeller on and old CNC bender
I still have to make a PCB
and fine tune it
Thank you all for your input
