## Clock Phase
If you are facing issues with pixels being 'off' by 1 px to the co-ordinate requested, or experiencing ghosting, then it could be due to the 'clock phase' setting. For some panels data is clocked 'in' with negative clock edge, others with the positive.
By default this library is configured to 'clock data' in with a positive clock edge. To change this, configure with `mxconfig.clkphase = false;`. Refer to the [example](https://github.com/mrcodetastic/ESP32-HUB75-MatrixPanel-DMA/blob/a5d6611b65c365a252e6787e0afc267cf63c1996/examples/1_SimpleTestShapes/1_SimpleTestShapes.ino#L98) for the relevant line that is commented out.
## Power, Power and Power!
Having a good power supply is CRITICAL, and it is highly recommended, for chains of LED Panels to have a 1000-2000uf capacitor soldered to the back of each LED Panel across the [GND and VCC pins](https://github.com/mrfaptastic/ESP32-HUB75-MatrixPanel-I2S-DMA/issues/39#issuecomment-720780463), otherwise you WILL run into issues with 'flashy' graphics whereby a large amount of LEDs are turned on and off in succession (due to current/power draw peaks and troughs).
