Experimental, use with care. The SPI protocol is a "standard" for serial communication, however there exists many variants. This document only describe the four modi typical used in the Arduino ...

Hi, I was just reading the wiki page on SPI Hardware Or Bit banging. It says pin 53 is the clock on ATMega2560 based boards. I presume this is the Arduino pinout number. Except if we look at the ...

The data result of all expressed on 3.5-inch display will show in IV-curve and PV-curve form. However, the limitation of MPPT device was can't measuring of high-power solar cell panel more than 25V ...

The Waveshare 1.69-inch IPS touch LCD is a 1.69-inch rounded display with 240×280 resolution and a 262K color range. The display driver (ST7789V2) and touch controller (CST816T) are integrated ...

The chip expects 3.3 V logic so he made use of a MC74LVX50 hex buffer to tailor the Arduino’s 5 V. Currently he’s working on revision two of the shield, which will include SPI flash memory.
