MicroPython Forum

The Arduino library is pretty well documented: https://github.com/olehs/PZEM004T It's communicates over serial, so I'd start by getting a USB-serial module and fire commands at it an manually interpret the responses. Theres a python3 version here: https://www.raspberrypi.org/forums/viewtopic.php?t=1...

So far I have: * Publish your project on Github. eg. https://github.com/mcauser/micropython-am2320 * Add setup.py to your project. eg. https://github.com/mcauser/micropython-am2320/blob/master/setup.py * Tag with a version, eg 1.0.0. eg. https://github.com/mcauser/micropython-am2320/releases/tag/v1....

I have made a few drivers for my various micropython projects. To reduce code duplication, I'd like to remove drivers from the projects and use upip to install them instead. Trying to figure out how to get from here: https://github.com/mcauser/micropython-am2320 To here: upip.install('micropython-am...

If you need penetration through plastic, walls, etc, have a look at some of the cheap doppler microwave sensors now available. eg. HB-100, HW-MS03, WB3-12, XYC-WB-D, HFS-DC06, RCWL-9196 and RCWL-0516 They operate on 2.4GHz, 5.8GHz or 10.5GHz, so watch out for wifi interference. The guy with the Swis...

To enable an external mma7660, you'd need to use a different firmware. When it's compiled, there's a bunch of features that are enabled/disabled, based on what the board has. The pyboard had a mma accelerometer, so it's firmware has it enabled. Have a look on your pcb for a chip around 3-5mm square ...

Which specific VET6 board are you running? Can you post a link or photo (eg. imgur.com)?

I have compiled the latest v1.9.1-29 firmware for the BLACK_F407VE board and attached to the release: https://github.com/mcauser/BLACK_F407VE/releases/tag/v1.0.0 Logged output here: https://gist.github.com/mcauser/8d0e75dfeda0d40c0a57a60a29aa01bf Also compiled v1.9.1 for my other STM32 boards: https...

Thanks for the update. Amazing effort to date. Well done team! IMHO scrap video tutorials in favour of regular text/screenshot based tutorials, and add more real-world examples. eg. https://github.com/pfalcon/picoweb https://github.com/pfalcon/notes-pico More bang for your buck without the additiona...

From what I have read, that sounds correct.

This is the same model, only 20c cheaper:

Well, it takes 7 seconds to draw 8192 pixels. screen.redraw() accepts dimensions, so you can do a partial redraw. Moving the calculations to C would speed things up quite a bit. SPI is running at 800khz, so thats 2 orders of magnitudes more than there are number of pixels. The bus is not the bottlen...
