Hopefully not too much of a silly question.
I’m talking to SD cards over SPI just using a breakout plank.
Documentation seems to suggest you initialise in 100-400khz and after that bump it up.
There doesn’t seem to be a way I can see to edit spi speed in session and exiting shuts off voltage. This means you can’t initiate in 400 and then move up later on.
Am I missing something or just not understanding something?
Any help would be appreciated.
