The HT16D35A/HT16D35B are high accuracy constant current and memory mapping LED display controller/drivers. The maximum display capacity of the devices is 224 patterns composed of 28 rows and 8 commons. The devices can generate a 64 step Gray Scale (PWM data) using software controlled PWM circuitry and 64 LED illumination levels using software controlled PWM circuitry.
this library is still unfinished
Download the .zip file from Github, in Arduino go to Sketch -> Include Library -> Add .ZIP Library... and select the downloaded .zip file.
The library example can then be opened under File -> Examples -> HT16D35A LED Driver
