![]() ![]() Compared to UART and I2C, it is the fastest. The display has a ST7789V controller and only 3wire SPI is available as an interface. Did anyone has exp Hi guys, I try to get a combination of Teensy 3.2 board and a TFT from DAS Technology (chinese manufacturer) run. SPI operates at full-duplex where data can be sent and received simultaneously. The display has a ST7789V controller and only 3wire SPI is available as an interface. of the datasheet tells me that the maximum SPI speed to perform a SPIread is. SPI, which stands for the serial peripheral interface, is similar to I2C where it is a different form of serial-communications protocol specially designed for microcontrollers to connect. But, for my project, I want to maximize the communication speed between the LCD and the Arduino DUE. The chip has 3 address pins and can set 8 different addresses, so 8 modules can be connected through two IIC buses to achieve up to 128 IO extensions. Everything works as expected when using the Adafruit library. MCP23S17 is a high-speed SPI interface, up to 10MHz. The IO interface has a strong driving capacity, and the current and current can reach 25mA. To use pin MOSI to transmit data towards the console, and SCK to follow the clock coming from the console. ![]() the idea is to use module SPI of the AVR in SLAVE mode. The chip is fully functional, each IO can be configured as input or output arbitrarily, and it can be used for color weaving to use pull-up resistors, and configured as input sub IO can enable interrupt function. hello I try to simulate a nes controller with an Arduino to communicate through the controller port of a Nes. Often SPI is used by other libraries (like. This module is the 16 IO extension module of the SPI interface, and uses the MCP23S17 chip of MicroChip. Only SPI master mode is supported, for control of SPI peripheral chips. ![]()
