Your current version is much better than the one I used before, editing REPL history commands works fine if not changing leftmost character.
I fixed the issue by adding two escape sequences support.
I also gave this tool its own repository:

Thank you!
I tested your new repo, verified that it fixed the issue.
Tried many things to find issues, but found none
I terminated my repo pointing to your new dedicated FBConsole repo:
https://github.com/Hermann-SW/micropyth ... -statement
And I added your FBConsole to MicroPython Wiki:

Thank you for testing and updating the wiki !

Hi,
is it possible to add REPL redirect to
ILI934X TFT displays?
Is it necessary to have display which has hardware scrolling?

Hi vitalis,
is it possible to add REPL redirect to ILI934X TFT displays?
It seems to be possible.
FBConsole requires a display to have following APIs:
Code: Select all
fill(self, color)
fill_rect(self, x, y, w, h, color)
scroll(self, dx, dy)
hline(self, x, y, w, color)
text(self, c, x, y, color)
and the driver you mentioned (ili934xnew.py) has:
Code: Select all
fill_rectangle(self, x, y, w, h, color=None)
scroll(self, dy)
chars(self, str, x, y)
set_color(self,fg,bg)
So, you need to write a wrapper class to provide API for FBConsole and it seems not that difficult.
fill() and hline() can be easily implemented using fill_rectangle.
text() can call set_color() and chars().
To implement scroll(self, dx, dy), use scroll(self, dy) and ignore dx. It works because dx is always zero.
I wrote a wrapper class for ST7735 the other day and it works fine.

Is it necessary to have display which has hardware scrolling?
Not mandatory. It is simply a matter of display speed.

Thank you! I will try to write such wrapper.
Meanwhile I Am trying to do REPL redirecting to one of those extra-cheap 20x4 LCD with I2C controller.
Just to dream - maybe it will be good to have a native support for common displays from Micropython itself... Performance wise should be much faster

One of the aspects is to find keyboard which can be attached using a serial interface. ASCII keyboards are gone. But some people made alternatives, besides USB to serial adapters (e.g.
https://www.adafruit.com/product/1136), like:

I've built up a SnapOnAir board which functions as a keyboard and display for a Raspberry Pi, it uses an ILI9341 based display and a TCA8418 I2C keyboard encoder. I would like to get it working as a standalone Micropython unit. I guess it would involve code which processes the keypress events and provides the readinto function that the dupterm documentation mentions. Having said that I currently have no idea how to do it.
Edit: you could use a TCA8418 to repurpose a laptop keyboard, I've got some spare IC's, and DIL adapter boards on order, so I may well have a play with some hardware.
