Problems using this library with FastLED

[thorstenweber83]

When trying to include FastLED in the same project i use PDQ_GFX.h and PDQ_ST7735.h in i get a lot of warnings and errors like this one:

In file included from /home/user/Arduino/libraries/PDQ_ST7735/PDQ_ST7735.h:62:0,
                 from /home/user/projects/arduino-project/arduino-project.ino:15:
/home/user/Arduino/libraries/PDQ_ST7735/PDQ_FastPin.h:268:52: error: previous definition of 'class FastPin<17u>'
 #define _DEFPIN_AVR(PIN, MASK, L) template<> class FastPin<PIN> : public _AVRPIN<PIN, MASK, _R(PORT ## L), _R(DDR ## L), _R(PIN ## L)> {};

I suspect the Problem lies in your Library already including FastPin.h, but im no expert in C/C++ matters. I could really use your help. Thank you :)

Hello, Yes, no doubt there is a conflict when both libraries are included from the same source file. I never considered a project using both FastLED and an LCD (D'oh). One possible solution is to add a second ".ino" (or .cpp) file to your project and have one that use PDQ_GFX and another for FastLED (and don't "mix" them). Another idea if you know a bit about programming is to enclose all the PDQ_GFX stuff in a "namespace PDQ { ... PDQ includes here... }" (since it is almost all in a header, mostly you mostly just need to include the headers inside the namespace and add a "using namespace PDQ" above your code). Finally a simple, but brute force way to fix it is to "search and replace" for FastPin in the PDQ_GFX files and replace it with (e.g.) PDQFastPin so it won't conflict (I should probably do something like this for a future version of the library). Hopefully one of these will work for you (let me know). :-)

i found for PDQ_ST7735 , swap() function is missed. I think its mean swapValue()

Some China TFT 1.44 128x128 SPI V1.1 REDTAB or SPI V2.1 BLACKTAB has deffect to incorrect Y axis. Choose in PDQ_graphicstest:

PDQ_ST7735_config.h

define ST7735_CHIPSET ST7735_INITR_144GREENTAB

In file library PDQ_ST7735.h line ~397 changes //spiWrite16(x0+2); // XSTART //spiWrite16_preCmd(x1+2); // XEND spiWrite16(x0); // XSTART spiWrite16_preCmd(x1); // XEND

line ~413 changes //spiWrite16(y0+3); // YSTART //spiWrite16_preCmd(y1+3); // YEND spiWrite16(y0+32); // YSTART spiWrite16_preCmd(y1+32); // YEND thanks for fast libs. very cool. I need to quality animate:) GL!!!

Hello. Whether the library will be adapted under esp8266 ? The interesting speed allowing to do full animation.

Freedi, thanks for the "Y axis fix". I will add this as an option next chance I get. This may explain a few other reports I got with ST7735 having issues.

As far as ESP-8266, that is an interesting idea, but this PDQ_GFX library is mostly focused on low-level AVR issues. ESP-8266 can probably run original Adafruit version reasonable fast (I would think).
