[hfbuhun]

This code is very good，but There is a problem for W25Q256, The instruction is 21h instead of 20h for a 32-bit address

I specially check... function is 20h, but I havent got a w25q256 to test...

I know code contains bugs on writeBytes function....
this library is good as first point, but need to prepare to use....

我专门检查了...功能是20小时，但是我没有w25q256来测试...

我知道代码中包含关于writeBytes函数的错误。...
该库虽然很好，但是需要准备使用。

Sorry, my model is W25Q256JV。

hello. thank you for your feedback. But i think it is work correctly.

The Sector Erase instruction sets all memory within a specified sector (4K-bytes) to the erased state of all
1s (FFh). A Write Enable instruction must be executed before the device will accept the Sector Erase
Instruction (Status Register bit WEL must equal 1). The instruction is initiated by driving the /CS pin low
and shifting the instruction code “20h” followed a 24/32-bit sector address (A23/A31-A0). The Sector
Erase instruction sequence is shown in Figure 36.
