三星K9F1G08U0E(128MB,NAND FLASH) STM32平台驱动程序（模拟时序）
2024-04-18 08:13:19
STM32平台下模拟时序驱动K9F1G08U0E，主要目的为了解、学习NAND FLASH的功能特性，没有使用STM32的FSMC（火龙开发板硬件为模拟时序驱动），纯粹自娱自乐，如对你有帮助，不胜荣幸，呵呵。

7 驱动代码针对K9F1G08U0E时序而写，K9F1G08U0E与NAND512W3A2C,Pin to Pin兼容。
8 驱动运行平台STM32F103。
9 驱动实现功能：
10 1）Page Read
11 2) Page Program
12 3) Block Erase
13 4) Read Status
14 5) Read ID
15 PE0~PE7 -> DB00~DB07
16 PD6 -> CL
17 PD5 -> AL
18 PD14 -> W
19 PD15 -> R
20 PD7 -> CS
21 PB5 -> R/B
