Addressing W25Q64 flash IC
I am using a [W25Q64 flash ic](https://www.pjrc.com/store/w25q64fv.pdf) to store some stuff for an ESP-32 project. I used [this](https://github.com/nopnop2002/esp-idf-w25q64) library from Github as it seems intended for ESP. It seemed weird that the read function uses two 16-bit parameters as the address and the write function uses one 32-bit address, but it seemed to work.. Until I tried to write and read beyond page 255. I figured I'm doing something wrong with addressing and tried to figure it out by the memory layout chart in the datasheet. Unfortunately I just cant seem to grasp it. I also can't find another library that has explanatory comments in the write/read functions. I'm looking for some clear information about addressing this chip or a well commented library/example. Any advice is greatly appreciated, thank you!
