void W25qxx_EraseSector(uint32_t SectorAddr) BUG For W25Q256
This code is very good，but There is a problem for W25Q256, The instruction is 21h instead of 20h for a 32-bit address
https://www.winbond.com/resource-files/w25q256fv_revg1_120214_qpi_website_rev_g.pdf 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....
https://www.winbond.com/resource-files/w25q256fv_revg1_120214_qpi_website_rev_g.pdf 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。 https://www.winbond.com/resource-files/w25q256jv%20spi%20revb%2009202016.pdf page55
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.
