ESP8266 ( ESP-WROOM-02 ) SPI 通信- mgo-tec電子工作

ESP8266 SPI (Serial Peripheral Interface) module is used for communication with devices supporting SPI protocols. It supports the SPI protocol standard of 4-line communication in the electrical interface ESP8266 SPI master supports the communication protocols as shown in Table 2-1.

″ Touch LCD SPI for esp8266 (nodemcu) – NailBuster

Hi, I have just uploaded two projects to github that in my oppinion solve the problem with using ESP8266 modules as slaves to Arduino MCUs. Instead of the serial interface the SPI interface is used here.

ESP8266 Technical Reference - Espressif

1/28/2017If you plan to include a SPI device, prototype everything using breakout boards, if possible. GPIO15 can be configured as an output and driven high or low as needed. The pull down does not prevent this. If you search for ESP8266 projects using SPI, for example for TFT LCD, GPIO15 is used as the SPI chip select.

ESP8266 SPI 통신 테스트 (ARDUINO IDE) :: MCU_T_R_Y

/24/2018The main hardware difference is the ESP8266 is a 3. 3V device but the Arduino is 5V. The PZEM-021 is actually a mixture. The RN8208G metering chip is a 5V device. It is a SPI slave, the SPI master is an STM32 ARM processor that is 3. 3V but with 5V tolerant inputs.

For technical details of the underlying hardware refer to metalphreak's ESP8266 HSPI articles. Note. The ESP hardware provides two SPI busses, with IDs 0, and 1, which map to pins generally labelled SPI and HSPI. If you are using any kind of development board which provides flash, then bus ID 0 (SPI) is almost certainly used for communicating
