WebNov 21, 2024 · For this reason, there is no single pin the SPI can define for being used as CS/CC pin. However, it should give a GND or VCC value, thus a CS/CC pin should typically be configured as a digital input pin (as master) for each slave. (See remark of KIIV too); as slave the CS/CC pin should be a digital output pin. WebAug 7, 2024 · Every IC with multiple CS# lines which I've seen so far, had multiple features and each CS# would select a particular feature, or a combination of CS# lines would select a feature. So, the right answer is "There is no common behavior. Read the datasheet.", rather than "Typically, yes." On that note, -1 (no hard feelings). \$\endgroup\$

When a device's Chip Select pin is low, it communicates with the Controller. When it's high, it ignores the Controller. This allows you to have multiple SPI devices sharing the same CIPO, COPI, and CLK lines. WebSep 18, 2024 · The pin names typically used for SPI are: GND : Power Ground. VCC : Power input. CS : Chipselect. SCK/SCLK (SD-Clock): SPI Clock. MOSI (SD-DI, DI) : SPI Master out Slave in. MISO (SD-DO, DO) : SPI Master in Slave out. CD: Card Detect (see comment of rollinger below (thanks). On an Arduino Uno the SPI pins are: dsh log in
