Data Definition of the single frames
One frame consits of 2 blocks (à 8x9 LED-matrix) or 3 blocks (à 5x6 LED-matrix). This configuration is set in the AS1119 config register ( see
In the internal DPRAM of the device 6 frames can be stored. For each frame the following parameters have to be stored.
- LED is ON or OFF.
- LED is steady ON or blinking.
- The intensity of every single LED can be set via a 8 bits PWM.
Note: After power-up the data in the DPRAM is undefined (either ‘0’ or ‘1’).
2 Blocks with 8x9 LED Matrix
The AS1119 can be configured to control two seperated blocks of LEDs matrixes. This must be set via the bit D0 in the AS1119 config register
