The incandescent lamp simulator chews up a lot of CPU time twiddling the LED lines at faster rates than the stock version does in order to get the variable brightness and fading effects. If the Broadcom processor's GPIO pins can run in PWM mode, we might be able to use them for this simulation at the slower update rate of the <tt>no-lamp-simulation</tt> branch, allowing all users to have it, even those using the Pi Zero. tangent added on 2017-01-06 21:00:56: Can't do it. A Raspberry Pi only has one hardware PWM. LAME. | ||||
