Detailed Description

SBK_HT16K33 Library

Arduino-compatible driver for controlling HT16K33 LED matrix ICs using I2C. This library is designed for 8x16 LED matrix control and is compatible with SBK_BarDrive if used, but can also be used standalone.

✅ Features

  • HT16K33 driver for 8x16 LED matrices or bar meters
  • I2C-based control with brightness control and display clearing
  • Compatible with SBK_BarDrive (optional)
  • Efficient buffer-based updates

📦 Installation

  1. Download or clone this repository:
    git clone https://github.com/sbarabe/SBK_HT16K33.git
  2. Copy it to your Arduino libraries/ folder

🧪 Example (standalone usage)

#include <Wire.h>
#include <SBK_HT16K33.h>
SBK_HT16K33 ht(0x70); // default I2C address
void setup() {
Wire.begin();
ht.begin();
ht.setBrightness(10);
ht.clear();
// Light up a diagonal on 8x8 block
for (uint8_t i = 0; i < 8; i++) {
ht.setLed(i, i, true);
}
ht.show();
}
void loop() {
// Nothing here for now
}
SBK_HT16K33.h
Arduino driver for controlling a single HT16K33 I2C LED matrix or bar meter.
SBK_HT16K33
I2C driver wrapper for HT16K33 compatible with SBK_BarMeter and SBK_BarDrive.
Definition SBK_HT16K33.h:61

🔧 API Summary

Method Description
begin() Initializes the HT16K33 driver
setLed(row,col,v) Sets LED at (row, col) to ON/OFF
getLed(...) Gets the current buffer state
clear() Clears the internal buffer
show() Pushes the buffer to the display
setBrightness() Adjusts brightness level (0–15)

🧩 Integration with SBK_BarDrive (optional)

To use this library with SBK_BarDrive:

  • Include <SBK_HT16K33.h> before including SBK_BarDrive.h
  • Then create a SBK_BarDrive<SBK_HT16K33> instance as shown in SBK_BarDrive examples.
