Based on the STM32 HAL project but the code is easy to modify and use on another platform. Im using CMSIS drivers for AT45DB and SPI. 7-volt DataFlash. After the last bit of the opcode is shifted in, the eight bits of the status register, starting with the MSB (bit 在项目中用到2M Byte容量的Flash芯片AT45DB161，用来存放字库文件，这两天在写AT45DB161的读取控制程序，在参考网上的一些控制代码的基础上，编写成功。现总结经 Before continue let me tell you that, this external flash is written by a LoRa module and contains a binary data from cloud which is actually a new firmware. Manufacturer: 45dbxxx library for stm32 hal. Page: 55 Pages. After I call fformat function Im getting stuck at EraseChip The buffers allow receiving of data while a page in the main memory is being repro-grammed, as well as reading or writing a continuous data stream. And Keil filesystem. 在本主题中，我们将深入探讨如何使用 STM32 的硬件SPI（Serial Peripheral Interface）接口来读写AT45DB161 D，这是一款常见的串行闪存芯片。 AT45DB161D可通过片选引脚（/CS）使能，并通过3-wire接口访问，3-wire由串行输入（SI），串行输出（SO），和串行时钟（SCK）组成。所有的编程和擦除周期都遵循自时序。一些 Description A simple library designed to perform basic operations with serial flash memory devices of the AT45DB family.
