Re: Ethernet Adapter for PyBoard Which?

I wanted to see if anybody got this working with the W5500 also, even though it says it is not tested, it still says it should be supported.

Re: Status of MicroPython ESP8266 project

Sorry to hear about your health. Similar feeling as Roberthh, good documentation and up to date written tutorials to me are more important. They are easy to update small changes, searchable, more version-able and overall much more concise. That being said, I like watching "overview" videos, which ad...

Re: Bringing MQTT to generic MicroPython boards

This is interesting to me, I like making the ESP8266 as a simple MQTT "Peripheral" and let the main processor do the fancy stuff. With how crazy cheap the ESP8266 is, but how limited it is in IO, this makes a lot of sense.

Re: Controlling pyboard with other pyboard

If you were not looking for REPL support, RS485 or CAN would be good multi-drop communication methods.

Re: micropython R1.9 ETA @@ released @@

Maybe I am just adding to the noise, but I would also agree that high/low is the most concise and describes the states the best. True/False and 1/0 mean about the same in my head, and I often use them also, but I feel it does not describe it as well when thinking pin states. Those three options seem...

Re: CAN bus possible

Hello Dino, As Dave said, it is good to be aware of the 2 components to implementing CAN bus. I usually hear them called the CAN peripheral, which ideally is built into the microcontroller, and the transceiver, which is rarely part of the microcontroller. The peripheral is for dealing with the proto...

ESP32 CAN bus

I have found some mentions of CAN with the ESP32 module, but not in any of the micropython ports (Pycom and here). There peripheral is in the ESP32, so it is a matter of code and testing. https://esp32.com/viewtopic.php?f=12&t=380 Unfortunately I do not have the time or experiences to do this effici...

Re: help adding string module to mu or any other ide

My two cents is it would be nice to use zfill the same way as in the standard python library, especially when using micropython unix.

I also know if I am complaining that I should contribute to the project and add it myself :-)

Re: rshell - connecting my lopy board?

rshell works great with lopy and wipy. It its my main tool for those devices. I use FTP sometimes to manage a bunch of files but rshell recently added recursive copy, which I have not tested yet.

You might have to run this under sudo user if permissions gives you issues.

Re: Design my own pyboard, basic questions..

Also USART based bootloading can be done without a crystal. Dave and his brother have post about this, and it is a good backup. Because there is a Python interpreter layer there really is not benefit of using a fancy programmer since you do not get to do the low level debugging those offer. Sometime...
