[BUG] compile ia_creality fails

[rmbq]

Did you test the latest bugfix-2.1.x code?

Yes, and the problem still exists.

Bug Description

after f0cc8bd i can't compile with
#define DGUS_LCD_UI IA_CREALITY
and
#define MOTHERBOARD BOARD_CREALITY_V453

Errors:

[bob-anthony]

This environment compiles fine using the official InsanityAutomation repo. I can't imagine why code hacked in without the original developer's approval or support wouldn't operate as expected.

[ellensp]

Interestingly on mega2560 (what this display was designed for) It compiles without issues.

[ellensp]

@rmbq Please test this PR

[rmbq]

@ellensp now it compiles but marlin doesn't communicate correctly with the screen.
using this line
char (*__kaboom)[sizeof( int )] = 1;
from here
shows sizeof(int) is 4. With f0cc8bd all unsigned int and int are converted to uint16 or int16 and not uint32 or int32

[ellensp]

yes, but on avr they are 2 bytes, not 4. Just changing them to 32 is not the answer. That is going backwards. Need to check if any actually exceed 16bit values..

[rmbq]

Probably the screen also needs int32 to works. Maybe we need the change the screen firmware to use 16 instead of 32.

[InsanityAutomation]

Be careful making changes with overloaded methods. This situation demonstrated fairly quickly why I didn't put this upstream. Try reverting the breaking changes, as I doubt this was the only UI broken.

[thinkyhead]

…why I didn't put this upstream…

@InsanityAutomation

I could use your help sorting out the Resistive Touch Screen code, as we're getting another one in support of the Ender-5 S1, and it would be awesome to have all the RTS screen common code in a root class, and then make sub-classes for the different variants. Plus, the Ender-5 S1 user interface is less than ideal, including not yet supporting folders on SD card.

As for the ambiguity of the overloaded methods, we can probably get those sorted by going through all the calls to RTS_SndData and just making sure we know the types in use and eliminating any lingering amibiguities, especially related to signed/unsigned and 8/16/32 bit. It's always a bit annoying to deal with C++ overloading in this area. Where needed, we can get rid of overloading and give these methods names that include the data size, such as RTS_SndData16 and RTS_SndData32, etc.

[thinkyhead]

@rmbq — Thanks for the report. I'll have this patched forthwith!

[thinkyhead]

@rmbq — There are a number of other compile errors with those configurations. What version of Marlin are you using them with? Do you have other modified files (e.g., pins) that cover these issues?

#error "SERVO0_PIN must be defined for your servo or BLTOUCH probe."
#error "TMC2208 or TMC2209 on E0 requires E0_HARDWARE_SERIAL or E0_SERIAL_(RX|TX)_PIN."
#error "CUSTOM_MENU_MAIN requires an LCD controller that implements the menu."
#error "DGUS_LCD_UI IA_CREALITY requires CLASSIC_JERK."

[thinkyhead]

@rmbq — Note that MachineCR10Smart is no longer used in mainline Marlin. It's been replaced with LCD_SCREEN_ROTATE 90.

[thinkyhead]

@InsanityAutomation — ICYMI I also made this change (since (uint8_t)n > 0xFFFF can never be true) so you should verify on your end that it is correct:

  void RTSSHOW::RTS_SndData(const int n, const uint32_t addr, const uint8_t cmd/*=VarAddr_W*/) {
    if (cmd == VarAddr_W) {
-     if ((uint8_t)n > 0xFFFF) {
-       snddat.data[0] = n >> 16;
-       snddat.data[1] = n & 0xFFFF;
-       snddat.len     = 7;
-     }
-     else {
        snddat.data[0] = n;
        snddat.len     = 5;
-     }
