Re: Exploring the SPI Master interface

hi
i have a play with spi and i take the bit banging method.
i use
GPIO 12 as MOSI
GPIO13 as MISO
CLK as GPIO5
CS as GPIO4
and maked as software spi as channel #2
i combinied this for playing next time with lcd and other doing.
here a little video from my play.
viewtopic.php?f=15&t=1255
my way is to make this next time in i2c too and ovelay spi and i2c by manageing this in fw.
next steps are sd card in micro form.
a next doing thing is a esp8266 as "slave" with other esp8266 for test in nodes and data transfer rate - only a test
best wishes!
