Re: Larger fonts on SSD1306 OLED displays

This forum supports MicroPython. CircuitPython is the Adafruit fork of MicroPython, and their SSD1306 driver differs from the MicroPython version. I don't know if Adafruit support using different fonts. A search on their forum or a query there might ...

Re: Larger fonts on SSD1306 OLED displays

Hello all! :) I'm new to circuitpython and programing overall. I did a simple project with SSD1306 OLED and DHT22. I would like to change a font size, the basic font is to small. Do I need to use some additonal library to change anything? Can anyone give me some advice what library I miss and give m...

Re: how to connect R307 finger print

... unconnected. You will have to solder across that bridge that you described (i.e. "short" those two pads). In case you haven't seen it already, Adafruit have a library which I think is for the R305 but might be useful to you to. https://github.com/adafruit/Adafruit_CircuitPython_Fingerprint/blob/master/adafruit_fingerprint.py

How to debug MicroPython using gdb ?

... printf somwhere (occuring before the REPL comes to life) but... nothing showed up. I'm using the J-Link EDU Mini connected to the SWD port of my Adafruit Pygamer on Ubuntu 19.04.

Re: New Bosch BME280 temperature, humidity, pressure sensor library

I have one here https://github.com/robert-hh/BME280, which I adapted from the Adafruit driver. I tested them on a Pycom device and on a ESP32 with micropython.org v1.11 firmware. I mentioned every source I could find, Bosch too (Adafruit did not), especially since ...

Re: unexpected/don't understand: SPI - cprrect register readings only when print statements included

It's possible that CircuitPython creates delays of this order by default. Bus accesses are mediated by Adafruit classes which set a lock to protect against conflicts. Obviously this must take some time. CircuitPython is designed for ease of use by beginners whereas MicroPython ...

Re: Reading voltage through A0 pin

Thank y lot. Actually the BME280 driver is just a port of the Adafruit driver. I invested some time to compare the calculations in the code with the original Bosch specifications and made a PR to adafruit for a change. The ADC of the ESP8266 is not very ...

Re: Thermal imaging camera (Pyboard D based)

Adafruit have an amazing video which brings out more detail than my bicubic interpolation (scroll down the page to see it). They achieve this using heavy-duty software running on a Raspberry Pi. I don't believe this combination ...
