Re: Receive and transmit IR remote codes

I have released this repo which supports infra red remote controls. Protocols supported are NEC, Sony, and two Philips options. A receiver and "blaster" driver are provided. Both are nonblocking. They are not reliant on uasyncio but are compatible with it. The transmitter is Pyboard specific. A tra...

Re: MicroPython using a Virtual Machine?

Hear me out here. I came to ask if Micropython was capable of being run on a Windows/Linux virtual machine. What i mean by this is, is there a way I can take the essential backend ROM or init code to set up μPy itself into an ISO, and package it snd run it on a virtualbox? And run it like it is an ...

Saving power on ESP32, running on single core and memory speed

Is it possible to shut down one of the cores in Micropython for the ESP32? And or clock down the memory speed? I know its possible to turn down the clock speed and that helps alot to save power. But would be great to see if its possible to save more. (Not for battery setup, btw)

Re: Multiaxis stepper motors using RMT

How high voltage do you wnt to run? Check out the 5160 stepstick. Super cheap. And there is also the 5160 bob. If you dont have super high power check out trinamic 5161. 5161 have fets included.

Re: Multiaxis stepper motors using RMT

What about using some Trinamic 5160 drivers over spi/uart? Instead of step/dir.
