Elegant Physical Config for Pyboard D
Hey all, I've been tinkering with esp32's for a while now, but I'm starting to see the light with the sheer speed benefits of the tasty stm32 on my pyboard D. I'm just wondering how on earth people are actually physically handling the i/o for this teeny device. It's so beautifully designed and made,...

Re: Newbie with bme280 issues
I had a bmp280 on a high altitude balloon project a little while ago that did this sort of random ENODEV occurences, so I just added Try Except statements like this (suited for your example) to make it so that it at least attempted to handle the error: while True: try: print(bme280.values) except OS...

Re: Newbie with bme280 issues
Your first error shows that your board couldn't detect the bme280 (ENODEV = error - no device detected). I've found from experience that the cheap bme/bmp280's often throw this error intermittently, for some unknown reason. Easiest way around this is to catch this exception every time you poll the s...

Re: TTGO T-Beam V1.0 GPS UART problems
Hi Thiago, I ended up going the 'easy' route and using the loboris port of micropython instead of using pythoncoder's GPS library, since loboris implemented an easy to use GPS parser in his default flashes. For initialisation of the GPS, here's what you need to do: import axp202, machine GPS_RX_PIN ...

Re: Drive WaveShare 2.7 inch e-Paper
Is your epaper actually a WaveShare epaper or is it some other brand? I've used Mccauser's drivers for waveshare epapers before and it worked flawlessly. Without delving too deep, triple checking the wiring that you've set up is probably the first action to take. Attaching your MCU's schematics is f...

Re: Help Launching Myself
Hi A, Your applications seem to not be overly time-sensitive or high frequency, so I would say the faster speed and interrupt times (thanks to the bare-metal uPy build) of a more expensive STM32 board are probably not required. Between the remaining popular platforms of ESP32 and ESP8266, I've found...

Re: A novel clock display?
Very cool watch face, almost looks naval and it seems a good way of countering ghosting. Might be worth mentioning that Garmin watches being made now (such as the Garmin Instinct, Fenix, Forerunner series) have a variant of Pebble's trans-reflective LCD in them with fairly similar tech behind it. I ...

Re: /sd gone
I now have 2 pyboard v1.1's that /sd has vanished from: rshell gives a "cannot access /sd" message and sure enough code that used to boot just fine from the /sd card no longer does (the code is still there if I look at it with a PC). Perhaps best to post your code for mounting the sd here. May also...

Re: _thread module status/documentation?
Firstly, thanks @tve and @pythoncoder for the explanations and links, they were an interesting read. The very first sentence in that asyncio tutorial section resounded very strongly with me :D The initial reaction of beginners to the idea of cooperative multi-tasking is often one of disappointment. ...
