PIO CANbus & ODBII on a Pico ?

Does anybody know if it is possible to implement CANbus using the RD2040 PIO? . . . clearly a CANbus transceiver such as a SN65HVD230 would be required to handle the differential voltage, but the question is can the PIO effectively replace the need for a CANbus controller such as the MCP2515 (and wi...

Re: rshell & Raspberry Pi Pico - date & time sync

Fantastic, thanks

minor tweak, I think line 1008 should use ‘mem32’ rather than ‘mem8’ as it is a 32bit register [this was an error in the original code I supplied, but it seemed to work irrespective]

Re: rshell & Raspberry Pi Pico - date & time sync

more detail and a working example of how to synchronise the Raspberry Pi Pico to a host computer . . . can this now be incorporated into rshell? #!/usr/bin/env python3 # # Vendor:Product ID for Raspberry Pi Pico is 2E8A:0005 # # see section 4.8 RTC of https://datasheets.raspberrypi.org/rp2040/rp2040...

A user on the Raspberry Pi forum posted this https://www.raspberrypi.org/forums/viewtopic.php?p=1810426#p1810426 , which appears to set the Pico RTC from within MicroPython. import machine import utime print() print(" YYYY MM DD HH MM SS") dateTime = (input ("Enter current date & time: "))+' 0 0' gi...

Re: How to get free space of internal file system?

This would do it . . .

Code: Select all

import uos
fs_stat = uos.statvfs('/')
fs_size = fs_stat[0] * fs_stat[2]
fs_free = fs_stat[0] * fs_stat[3]
print("File System Size {:,} - Free Space {:,}".format(fs_size, fs_free))

Re: ESP8266 is great (with ideas for improvement)

ESPlorer (http://esp8266.ru/esplorer/ solves this problem perfectly across multiple platforms (Windoze, Mac, Linux) and also provides for REPL access . . . wired rather than wireless though

Re: ESPlorer IDE supports MicroPython now

I have ESPlorer running on both a Mac and a Windows Laptop and am using Adafruit Huzzah Feather and DOIT ESP8266 boards . . . when using on the Mac I have the ability to transfer a file to the ESP8266, but this option is grayed out and not available on Windows. Is there a reason for this?

I have both a couple of pyBoard 1.1's and a number of ESP8266 Adafruit and NodeMCU/DOIT boards . . . Having spent the weekend playing with the latest 1.8 release of MicroPython on all of these, I am a little perplexed that the ESP8266 has support for the NeoPixel library built in but the pyBoard ver...
