Si otras librerías están usando interrupciones SPI no podrán acceder a SPI hasta que llames a SPI.endTransaction(). Este método no cambia los ajustes SPI establecidos. Si tu código, u otra librería, vuelve a iniciar SPI ( SPI.beginTransaction() de nuevo), se mantendrán los ajustes anteriores, a menos que, en la segunda inicialización se cambien explícitamente. W25Q32FV- 13 -6.1.3Quad SPI InstructionsThe W25Q32FV supports Quad SPI operation when using instructions such as“Fast Read Quad Output(6Bh)”, “Fast Read Quad I/O (EBh)”, “Word Read Quad I/O (E7h)” and “Octal Word Read Quad I/O(E3h)”. These instructions allow data to be transferred to or from the device four to six times the rate of datasheet search, datasheets, Datasheet search If you have just mastered this SPI interface, then looking at Dual and Quad SPI can be overwhelming. In this article, I am presenting all the useful and interesting facts on Quad-SPI. It is a serial interface, where 4 data lines are used to read, write and erase flash chips. The AXI Quad SPI connects the AXI4 interface to those SPI slave devices that support Standard, Dual or Quad SPI protocol instruction set. This core provides a serial interface to SPI slave devices such as SPI serial flash from Winbond and Numonyx. The Dual/Quad SPI is an enhancement to the Standard SPI protocol

Hola, estoy haciendo un proyecto en el que pretendemos comunicar 2 pc para envio y recepcion de datos por rf. Para el montaje del mismo comunico el pc por medio de RS-232 con un pic16F73 y este a su vez ira unido a un transmisor RFM12B. La idea principal es que el pc cree unos paquetes de 8 or SMBus. The SPI protocol typically uses four channels (two data lines, one clock signal, and one chip select bit) compared to I2C, which uses two channels (one data lane, and one clock signal). To achieve higher throughput, quad SPI (four data lanes) and octal SPI (eight data lanes) protocols are becoming more prevalent in high-performance XiP Enabled, Serial Flash Memory with 108 MHz SPI Bus Interface Features SPI-compatible serial bus interface 108 MHz (maximum) clock frequency 1.7V to 2V single supply voltage Supports legacy SPI protocol and new Quad I/O or Dual I/O SPI protocol Quad/Dual I/O instructions resulting in an equivalent clock frequency up to 432 MHz: Serial Flash devices. When using Dual SPI instructions, the DI and DO pins become bidirectional I/O pins: DQ 0 and DQ 1. 7.1.3. Quad SPI The FM25G01B supports Quad SPI operation when using the x4 and Quad IO instructions. These instructions allow data to be transferred to or from the device four times the rate of ordinary Serial Flash. Dual SPI The FM25G04C supports Dual SPI operation when using the x2 and dual IO instructions. These instructions allow data to be transferred to or from the device at two times the rate of ordinary Serial Flash devices. When using Dual SPI instructions, the DI and DO pins become bidirectional I/O pins: DQ 0 and DQ 1. 7.1.3. Quad SPI

Los dispositivos SPI se comunican entre sí utilizando un bus de 4 señales (MOSI, MISO, SCK, SS) y un esquema maestro/esclavo, en el cual el maestro inicia el protocolo de trasmisión de los datos.

In addition, Comunicaciones SPI. SPI es un protocolo alternativo a I2C que utilizan muchos dispositivos. Hoy en día es frecuente encontrar dispositivos que implementan tanto I2C como SPI. La elección de cuál utilizar depende de la aplicación: I2C utiliza menos pines y permite direccionar muchos más dispositivos.

Aunque a veces se define como "una versión and the lower level quad SPI driver, llqspi. The controller issues high level read/write commands to the lower level driver, which actually implements the Quad SPI protocol. Pictorally, this looks something like Fig. 2.1.
