Finally a dynamic controller which is easy to implement and use. with lesser IO pins than V1, (reduced by around 50%) An ic with higher pin count is hard to manage, synthesize and program.
Issues Deteccted on WS2812b Led drivers. while testing there seems to have some discrepancies with the lighting. They generally remain in the range of acceptable error, ie x value will only produce x color, the issue is in the brightness which seems to be messed up. These will be updated when i get back to it.
- Dout -> AR[0]
- enable -> SW[0]
- clk -> H16 Pin from Eth PHY[Internal Oscillator] [125MHz]
- red_e -> btn[0]
- green_e -> btn[1]
- blue_e -> btn[2]
- refresh_led -> btn[3]
- Data -> GPIO[7 0]
- red_e -> 8
- green_e -> 9
- blue_e -> 10
- refresh_led -> 11
The data is fed into the data pin and the the x_e is toggled from [1 -> 0 -> 1 -> 0] casusing the data to be absorbed into x_v. The implemented design has OR module to accept from both external and internal triggering. refresh_led is supposed to be toggled inorder for the color to be absorbed into the module I use PYNQ PS to input the RGB values to the module
this is based on Project of mine based on Lightdriver by anfractuosity modeled on a circular ws2812b ring consisting of 24 LEDs
Demo is given Below.
