CRT

Library with a set of functions for CRT Correction of LEDs

• tabular CRT 8 bits (heavy, fast and beautiful)
• square CRT 8 and 10 bits (lighter, but slower)
• cubic CRT 8 and 10 bits (better square, but even slower)

compatibility

Compatible with all arduino platforms (used arduino functions)

Installation

• The library can be found by the name ** CRT ** and installed through the library manager in:
  • Arduino ide
  • Arduino ide v2
  • Platformio
• [download library] (https://github.com/gyverlibs/crt/archive/refs/heads/main.zip). Zip archive for manual installation:
  • unpack and put in * C: \ Program Files (X86) \ Arduino \ Libraries * (Windows X64)
  • unpack and put in * C: \ Program Files \ Arduino \ Libraries * (Windows X32)
  • unpack and put in *documents/arduino/libraries/ *
  • (Arduino id) Automatic installation from. Zip: * sketch/connect the library/add .Zip library ... * and specify downloaded archive
• Read more detailed instructions for installing libraries [here] (https://alexgyver.ru/arduino-first/#%D0%A3%D1%81%D1%82%D0%B0%BD%D0%BE%BE%BE%BED0%B2%D0%BA%D0%B0_%D0%B1%D0%B8%D0%B1%D0%BB%D0%B8%D0%BE%D1%82%D0%B5%D0%BA)

Update

• I recommend always updating the library: errors and bugs are corrected in the new versions, as well as optimization and new features are added
• through the IDE library manager: find the library how to install and click "update"
• Manually: ** remove the folder with the old version **, and then put a new one in its place.“Replacement” cannot be done: sometimes in new versions, files that remain when replacing are deleted and can lead to errors!

initialization

No

Usage

`CPP Uint8_t CRT8_Table (Uint8_T VAL);// 8 bit CRT from the table Uint8_t CRT8_SQUARE (UINT8_T VAL);// 8 bit CRT square Int10_SQUARE (Int Val);// 10 bit CRT square uint8_t CRT8_cubic (Uint8_t Val);// 8 bit CRT cubic Int10_cubic (Int Val);// 10 bit CRT cubic `

Example

`` `CPP // An example with a smooth flashing LED

#incLude <CRT.H>

VOID setup () { Pinmode (13, output); }

VOID loop () { static int vel = 0; // Shim on 13 pin for dough // SoftPWM (13, Val);// naked meaning SoftPWM (13, CRT8_Table (VAL));// through CRT

// algorithm of smooth blinking Static uint32_t tmr; if (millis () - tmr> = 5) { TMR = Millis (); static int8_t dir = 1; val += dir; if (val == 255 || val == 0) die = -Dir;// unfold } }

// Soft Shim VOID SoftPWM (Byte PIN, Byte Val) { Static Byte Count; Count ++; if (Count == 0) digitalWrite (PIN, 1); if (Count == val) digitalWrite (PIN, 0); }

bugs and feedback

Create ** Issue ** when you find the bugs, and better immediately write to the mail [alex@alexgyver.ru] (mailto: alex@alexgyver.ru) The library is open for refinement and your ** pull Request ** 'ow!

When reporting about bugx or incorrect work of the library must be indicated:

• The version of the library
• What is MK used
• SDK version (for ESP)
• version of Arduino ide
• whether the built -in examples work correctly, in which the functions and designs are used, leading to a bug in your code
• what code has been loaded, what work was expected from it and how it works in reality
• Ideally, attach the minimum code in which the bug is observed.Not a canvas of a thousand lines, but a minimum code
