Arduino/Moteino library for read/write access to SPI flash memory chips. This works with 256byte/page SPI flash memory such as the4MBIT W25X40CLSNIGused onMoteinofor data storage and wireless programming. For instance a 4MBit (512Kbyte) flash chip will have 2048 pages: 256*2048 = 524288 ...
Arduino SPI + SPI Flash芯片W25Q80BV W25Q80BV是台湾华邦电子(Winbond)生产的8M-bit串行flash芯片。主要特性有: 工作电压:2.5 ~ 3.6 V 功耗:读写(active)时4mA,低功耗(power-down)时<1μA 容量:8M-bit/1M-byte,包含4096个页(每页大小256字节)
