Damien George	033c32e694	esp8266/esp_mphal.h: Fix I2C glitching by using input mode for od_high. Certain pins (eg 4 and 5) seem to behave differently at the hardware level when in open-drain mode: they glitch when set "high" and drive the pin active high for a brief period before disabling the output driver. To work around this make the pin an input to let it float high.	2018-03-12 12:45:09 +11:00

esp8266/esp_mphal.h: Fix I2C glitching by using input mode for od_high.

Certain pins (eg 4 and 5) seem to behave differently at the hardware level
when in open-drain mode: they glitch when set "high" and drive the pin
active high for a brief period before disabling the output driver.  To work
around this make the pin an input to let it float high.

all: Update Makefiles and others to build with new ports/ dir layout.

This is to keep the top-level directory clean, to make it clear what is
core and what is a port, and to allow the repository to grow with new ports
in a sustainable way.
