IR demo code with ESPBasic alpha 21
Posted: Tue May 03, 2016 5:47 pmHi all,
I prepared a little demo program showing how use the new IR functions available with the alpha 21.
The code is the following :
To make it works properly, you must download the image attached and upload it in the ESP module using the [FILE MANAGER].
The demo works with a IR led connected on the pin 15 and, optionally, an IR receiver connected on the pin 5.
Running the program you'll be able to click any key on the remote controller and the corresponding NEC code will be sent through the LED; optionally, if an IR receiver is connected, the code sent will be echoed as it will be received at the same time.
This demo code is very simple and shows also how create many buttons simply using one image and a little bit of HTML (and also a very little bit of javascript).
Hope this will illuminate the dark side of the ESP (with infrared light).
PS : I tested with chrome, could not work with firefox BUT works great on Iphone! Try it.

To make it works properly, you must download the image attached and upload it in the ESP module using the [FILE MANAGER].
The demo works with a IR led connected on the pin 15 and, optionally, an IR receiver connected on the pin 5.
Running the program you'll be able to click any key on the remote controller and the corresponding NEC code will be sent through the LED; optionally, if an IR receiver is connected, the code sent will be echoed as it will be received at the same time.
This demo code is very simple and shows also how create many buttons simply using one image and a little bit of HTML (and also a very little bit of javascript).
Hope this will illuminate the dark side of the ESP (with infrared light).
PS : I tested with chrome, could not work with firefox BUT works great on Iphone! Try it.
