Re: Fast crc8

Search on the net for example with lookup table, it is quicker than doing loop calculations.
crc8 is not very big.

Re: ESP-Now support for ESP32 (and ESP8266)

Glenn, thank you and well done for implementing ESP-NOW. Have been waiting for this for a long time, could be a game changer for me in using ESP's with micropython. Sorry haven't had a chance to look at all of the documentation or play with it yet, but is it possible to assign arbitrary Mac address ...

Re: Best driver for ili9341 display

I am currently actively considering supporting the ili9341 I hope you do, its a very popular and reasonably good value TFT display. I have and still am using them a lot in the arduino world, with SPI interface. AFAIK the most popular touch controller is resistive XPT2046 with SPI interface. There s...

Re: Official touch display with ESP32.

low cost way to build projects Its not a low cost display at £28.80 each in micropython store. I understand that Damian needs to make money somewhere, but ... For majority of hobbyists ILI9341 or similar TFT derivatives from Aliexpress is the way to go. Would also be good to have full numeric keypa...

Re: Beta of Thonny 3.3 with several MP-related improvements

Thanks for an update.
Have been using Thonny with uPython boards for a fairly long time without major issues.
Very easy and quick productivity on Windows environment.

Windows 10 antivirus complained as unsafe when downloading exe, had to create an exception, have reported it as safe.

Re: MQBoard - Micro-Framework for MicroPython Boards Managed via MQTT

Impressive development with emphases on reliable remote access. Well done and keep up a good work. I have been avoiding MQTT due to network reliability risk of having to relay on single WiFi AP and single non redundant broker. I guess it should be possible to implement MQTT network with a backup WiF...

Re: uart.read() error with PYBD-SF6W

Also, the PYBD is quite a bit faster than the pyboard 1.1, so if you call uart.read before the data has actually arrived back from the servo, then you'll get None, because the data just isn't there yet. Is it really that hard for developers to implement a callback functionality for UART, both Rx an...
