   # STM8 eForth: IR Remote Control for an RGBW LED Bulb  

   2

   These days IR remote control is still the cheapest option for consumer electronics.

   3

   I've long had the idea that Forth is ideal for scripting IR remote-controlled devices and I used the light bulb at my desk to learn how to do that with STM8 eForth.

   LED lamps of relatively high quality with a combination of white LED and RGB LEDs have a remarkable low price tag: the set below [costs no more](https://www.aliexpress.com/item/32884777814.html) than a regular white LED lamp.

   In my experience service life is much better (maybe due to a switched mode power supply with constant DC voltage and µC PWM control). The option for occassional colorful illumination is a bonus.

   # STM8L051F3: a low power Forth console

   In the stopped state the STM8L needs just a few µA - but in this state the console can't wake up the device:

   3

   the USART gets no clock. Only GPIO interrupts and peripherals that are clocked from the LSI or the LSE will work!

   4

   A possible solution is a pin-change interrupt on RxD for waking the core - and the USART - up.

   5

   In "Active-Halt" mode RTC and WUT peripherals run on 38kHz LSI or 32.768kHz LSE clock (see [here](https://gist.github.com/TG9541/0a71928f36e29ba92af34ec4312f2b25)). This means that it's possible to have a background task without keeping the core busy.
