Hello
I tried to re-compile the nodemcu firmware with lower SPI speed (4 MHz) following the instructions from this web site but I didn't make it

Could anyone compile the NodeMCU for lower SPI speed than the default 10 MHz that is used ?
For example, 1 or 2 or 4 MHz SPI speed

I found how to change the SPI speed but I cannot even do a compilation of the NodeMCU.

Thanks in advance

I just generated PR Add divider for arbitrary HSPI clock frequencies, resolves #674. It allows to specify any clock divider setting for spi.setup().
You should be able to compile it via the cloud service once it's merged to dev branch.
