Yes, either
a) copy /drivers/display/ssd1306.py to /esp8266/scripts/ssd1306.py and make/flash
b) start a webrepl and upload the file
c) enter paste-mode on a REPL and paste the contents of the file

Re: why os.listdir return ENODEV
One part I found a little confusing. In the Makefile there is an esptool.py attribute --flash_size=8m. If I have a board with 4MB flash, should I change this to --flash_size=32m? I am still seeing the error when trying to build and upload the latest version to a WeMos D1 Mini on OSX 10.10.5: If I fl...

Add DHT AM23xx series
I am looking to extend the current DHT implementation (1-wire) to cover all available DHT sensors, including the new I2C ones.
Details here: https://github.com/micropython/micropython/issues/2290
I would like to add support for DHT12, AM230x, AM231x and AM232x - around 15 compatible sensors.

Re: I/O expander
@joehunt588 both the SCL and SDA pins on the I2C bus need pull-up resistors (connecting each to VCC). Why? Because when they are missing, the pins are floating (sometimes high, sometimes low). eg. When the master scans the bus for devices, each devices pulls low to respond "hello, I'm here". When th...

Re: 3 UART Sensors (Noob)
What about 3 UART sensors connected to the same UART port, and toggle the power to each sensor so that only one is online at any given time?

Software serial?
Is anyone working on a software serial library? The ESP8266 has two hardware UARTs. UART 0 - TX and RX is used by the REPL. UART 1 - TX is free for use, however, RX is used by the onboard spi-flash. I have a GPS module and I am not sure how I can connect it. I need a free RX pin. Can I disable conso...

Re: I/O expander
i2c.scan() returns results in decimal. 0x20 == 32. If you are seeing a bunch of unrelated scan results, you may be missing pull-up resistors. I saw that when I was working with a DHT12 sensor. Added pull-ups and scan then returned a single item. Here is an example of using WeMos D1 mini + PCF8574 I2...
