用邏分去睇只會見到啲好工整嘅脉冲，唔會見到啲噪音。 我估佢意思係高 / 低電平唔係一條好靚嘅線條 啱，正是此意。 或者你可以搵其他 MCU 比較 會試吓。 試过睇呢塊 Arduino嘅 5V bus，一樣見到 ...

唔大鑊，好小兒科㗎咋。塊LED板用MAX7219 LED driver，用SPI只需三條訊號同兩條電源線，code有得download。 同埋 SPI 可以 set 時脈，應該可以避開干擾 塊板運作正常，放响機顶盒附近唔覺有干擾。

Quick, how do you wire up an SPI bus between a microcontroller and a peripheral? SCK goes to SCK, MISO goes to MISO, and MOSI goes to MOSI, right? Yeah. You’ll need to throw in a chip select pin, but ...

CAN-BUS is a common industrial bus because of its long travel distance, medium communication speed and high reliability. It is commonly found on modern machine tools and as an automotive diagnostic ...

This repo provides a version of the SPI libarary for the Arduio UNO R4, which uses the Renesas RA4M1 processor. In the standard distribution, 16 bit transfers are done as back to back byte transfers, ...

Arduino is launching new versions of the Uno board powered by a Renesas 32bit microcontroller. The Uno R4 comes in two versions: the basic Uno R4 Minima and the Espressif-equipped Uno R4 WiFi.
