Invert colors shortcut does not work on Python Edition calculators

[TheLastMillennial]

The invert colors shortcut does not work on my TI-84 Plus CE Python Edition L-0520P running OS 5.6.0, pressing [on]+[sto->] does nothing. All the other shortcuts seem to work: [8],[5],[2],[stat], and [prgm] all function normally.

The invert colors shortcut works on my TI-84 Plus CE L-0315 running OS 5.6.0 and it works on my TI-84 Plus CE L-0519M running OS 5.3.0 so I assume its an issue related to Python Edition calculators. All are using Cesium 3.4.1.

The fact that it works on the rev M indicates that it is still OK python-hardware (minus the ARM, but still) though... 🤔

Maybe something else changed between M and P that we don't know about...

This is a bug that only occurs when there is an arm chip present. The fix is to reset bit 4 of GPIO A (spi slave select) and make sure the spi is setup for communicating with the lcd (clock phase, clock polarity, master mono mode, flash, spi frame format, chip en, tx en, clk div = 12, data width = 3).

nice

Earlier today i got my TI 84 Plus CE Python to accidentally invert all the colors. (Yes i have cesium installed) But i cannot seem to repoduce it

On ti-83 premium we can just activate the inversion but we can't desactivate with on + In...

@Marasme That is a new feature, did you update to the latest release? (3.5.0)

[Marasme]

No not yet (I will do it in a few hours)

[retronbv]

Is there any hope that this bug will be fixed?

[mateoconlechuga]

I don't own a python calculator so I can't test anything. If you want to send me yours sure :P

[adriweb]

Get a paypal.me URL and ask everyone for like a dollar or 2, with enough people sponsoring Cesium development it should be quick \o/

This is the fourth time I’ve done it with no idea how :l
L-0321R

[mateoconlechuga]

I mean I know how, just go to the calculator's mode menu and then open Cesium.

It works on ti-83 premium !
Thanks...
