Product ID

The ESK-16D33A-M00 is an evaluation board for Holtek constant current LED driver HT16D33A . The board includes 360 white LEDs (in 10x36 matrix) and two HT16D33A ICs. An external MCU can control the LED display and effects of the board with the 3-wire SPI interface.

The Holtek HT16D3x constant current LED driver IC series integrate a PWM illumination control function, fade effect and rolling functions. In having the above features, they are suitable for use in applications such as mood lights, selfie lights, gaming keyboards, rhythm lamps, Bluetooth LED speakers, mobile phones backlights and home appliances which have color display panels.

Holtek provides a graphics editing software tool, LED Editor, to set up and edit patterns and colors, set rolling functions, set up fade and other functions, and then view the simulated display on the computer screen. The development platform, LED Workshop, is also provided to convert any user-edited graphics and instructions into MCU program code, ready for programming into the Holtek MCU. To use the software tools, this board should be used together with the MCU Board ESK-LED-100 and the debug adapter e-Link.

Question 1
Why the graphs I programmed to the development board differ from those in the LED Editor?

The issue might be caused by the below reasons:
1. If you would like to draw graphs on multiple panels, you need to set a consistent size for these panels.
2. If you would like to use multiple ICs, it is recommended to set them in "cascade mode".
 Step: Set one IC as “Internal system frequency + synchronous signal output mode” and set other ICs as “slave mode”.

  1. Development platform: HT16D3x LED Workshop, including LED Editor.
  2. Software: HT-IDE3000, Integrated Development Environment software for Holtek 8-bit MCU.
  3. IC: HT16D33A/HT16D33B, 16×16 Constant Current LED Driver, including datasheet, package information, etc.
