The operation of the SPI serial interface of isd1700 series follows the following protocol:
1. a spi processing starts at the falling edge of the/SS pin;
2. In a complete SPI instruction transmission cycle, the/SS pin must be kept low;
3. The MoSi pin of the chip exists in the rising edge of sclk, and the falling edge of sclk is output from the miso pin, an
The SPI protocol is a master-slave mode: The slave does not actively initiate access and always performs the operation passively.
CSN: Chip selection signal.
SCK: Clock signal.
Mosi:master output slave input, that is, the host outputs from the machine. The host can be understood to write from the device.
Miso:master input slave output, which is the host input from the slave. You can understand the host read from the device.

Fundamentals and Structure of SPI
The Serial Peripheral Interface (SPI) is a low-cost, easy-to-use interface developed by Motorola to enable data exchange between microcontrollers and peripheral chips. Unlike the standard serial interface, the SPI is a synchronous protocol interface, full-duplex communication, where all transmissions refer to a common clock,
The W25Q64BV array is organized to 32,768 programmable pages of 256-bytes each. Up to bytes can is programmed at a time. Pages can erased in groups of (sector erase), groups of (32KB block erase), groups of (64KB block erase) or The entire chip (chip erase)
BUSY is a read only bit in the status register (S0) which is set to a 1 if the device is executing a Page program, Sector Erase, Block Erase, Chip Erase or Write Status Register instruction

Editor's note: Unlike the traditional packet filtering firewall technology, this article starts with the application layer gateway technology and explores the use of WinSock2 SPI for network content access control. This is a new part of network security, or it provides a new idea for network security technology enthusiasts and R D personnel.
Firewalls can implement and execute network access policies. However, the traditional firewall technology focu
SPI bus protocol Introduction 1. Technical Performance
The SPI interface is the serial peripheral interface first proposed by Motorola for full duplex three-line synchronization. It adopts the master-slave mode architecture and supports multi-Slave Mode Applications. Generally, it only supports single master. The clock is controlled by the master. In the case of a shift pulse, data is transmitted in bit. Th

I recently participated in the adi udc (University Design Competition) competition to debug the touch screen. I used BF533. After debugging the SPI for half a day, I asked Yiqi, But I replied with a barrier, later I asked about the DSP technical support of Adi in China. They also debugged myCode, Really responsible, it turns out that I didn't add ssync (); this statement.Howeve
