Re: Input voltage limit, V+ as output, and actuator power supply options

I'd never spotted that discrepancy, believing 16V was the limit on a Pyboard 1.x. The voltage regulator is rated to 16V and has thermal shutdown, so nothing will go bang, but whether the regulator will start to shut down at 16V depends on factors such as whether you draw power from 3V3, on PCB layou...

Re: Fade 1 image to show another.

You might be more likely to get a response if you told us what hardware you plan to use: display type and host device.

Re: Installing uasyncio V3

In general there is no need to compile from source, unless you want to use "advanced" features like frozen bytecode. Daily builds are available here - simply download and install the latest "unstable" build. Despite the name, automated testing ensures that problems with these builds are very rare. A...

Re: Wifi bridge for RPI Pico

My understanding of @frustr8dlec's question was to ask whether it was possible to re-flash an ESP-01 with code for the WiFi MQTT bridge. Using the ESP-01 as designed is a given - but supporting MQTT that way would be, er, difficult.

Re: machine.RTC documentation

My advice is to use the pyb library for the Pyboard's RTC. Its documentation is correct, unlike that of machine.rtc.

All Pyboards are compatible with pyb.

Re: Reading multiples waves files in the same time

My comment was based on experience developing this library which can play MP3 and FLAC files via an external decoder chip. Handling a single audio stream from a file on an SD card was near the limit of what could be achieved, even with the number crunching of decoding the stream offloaded to externa...

Re: Receive and transmit IR remote codes

Given that you know you have a Sony 12 bit remote you should be able to run from ir_rx.test import test test(2) # The specific test for Sony 12 bit Then make a record of the data and address value associated with each button that is of interest. Transmitting using those values using the ir_tx SONY_1...

Re: nano-gui working on rp2

It isn't on PyPi. PyPi isn't much help for targets with no network interface.

Installation is done by cloning the repo to your PC and copying files to the filesystem, preserving the directory structure. Instructions may be found here.

Re: Reading multiples waves files in the same time

I think this is beyond the scope of microcontroller hardware for a variety of reasons.

I would consider using something like a Raspberry Pi hosting a full version of Linux. I'd ask for advice in a suitable forum: Linux has a variety of audio applications which can probably do what you are after.
