How it works
This is a custom implementation of an rgb mixer. The designs uses four inputs, two push buttons (i.e., inc and dec) and a 2 position dip switch (i.e., led[1:0]), and three outputs named PWM0, PWM1, and PWM2. The inc and dec buttons are used to increase or decrease the Pulse Widht of a selected output specified by the led[1:0] switch.
The following indicates the output selection based on the led[1:0] input.
led[1:0] |
Output |
| 00 | PWM0 |
| 01 | PWM1 |
| 10 | PWM2 |
| 11 | - |
How to test
Connect the push buttons and the dip-switches in a pull-up configurations to the following ports.
| tt_inputs | connection |
| ui[0] | inc |
| ui[1] | dec |
| ui[2] | led[0] |
| ui[3] | led[1] |
Connect an RGB LED to the following outputs.
| tt_inputs | connection |
| uo[0] | PWM0 |
| uo[1] | PWM1 |
| uo[2] | PWM2 |
External hardware
It is only required two push buttons, one dip-switch and an RGB LED and some resistors.
