Hi, could someone help me to understand how I can write just a single byte, long, int32 into a specific address, and then read it.
It should be, ext_flash_writeBytes(), to write, one byte = length 1.
And to read, ext_flash_readBytes(), this seems to work ok, but not the write. But I'm not sure if I have to send an opcode to the flash or ?
The following driver is supposed to be working, it's from the forum.
But how to use it? the PIC gets stuck in the writing process.
I'm trying to write as for ex:

I think this flash is only programmable in page mode, 256 bytes at time.
Needs page address and in the case of a single byte? an offset to that page, am I right?
