kandi X-RAY | SimpleNeoPixelDemo Summary

SimpleNeoPixelDemo is a C++ library typically used in Internet of Things (IoT), Raspberry Pi, Arduino applications. SimpleNeoPixelDemo has no bugs, it has no vulnerabilities, it has a Permissive License and it has low support. You can download it from GitHub.

A demonstration showing how easy it can be to drive WS2812 NeoPixels. The code sends bits and bytes directly to the LED strip without allocating memory for them, which allows to control hundreds of pixels with e.g. a small ATtiny85. The Adafruit NeoPixel library allocates 4 bytes per LED, and an ATtiny85 can only control a bit more than 50 pixels. So why use the Adafruit NeoPixel library at all? There are good reasons for both. Fast means less than 6 µs per pixel. This allows for some arithmetic operations, but a sine is already far too slow.

How to access member variable with gcc inline assembler code

QUESTION

How to access member variable with gcc inline assembler code

Asked 2019-Oct-06 at 11:19

So I've recently stumbled across the blog post NeoPixels Revealed: How to (not need to) generate precisely timed signals and supporting github project and am now trying to encapsulate the heart of this code into a c++ class so that I can access various neopixel strings from multiple arduino uno digital pins.

To do this, I've created a protected member variable (m_PixelChannel) which stores the pin required to access the light string. However, I can't get the assembly code to recognize the member variable. Below is the code that I'm trying to make work (which is more-or-less a direct copy-paste of the original code from the github project with a classname added before it):

I decided that I really didn't like the template<> approach that I used in the comment to Chris Dodd's response. So after a number of iterations, I was able to figure out how to make it work...
