What is CS pin?

What is CS pin?

The chip select is a command pin on many integrated circuits which connects the I/O pins on the device to the internal circuitry of that device. CS may also affect a power consumption or serve as cycle control in certain circuits (such as SRAM or DRAM).

What is SS in SPI?

Chip select (CS) or slave select (SS) is the name of a control line in the SPI bus used to select one (or a set) of the slave device (commonly called “chips”) out of several slave devices connected to the same master device. Figure 1. Single Master and Single slave devices. From Figure 1.

What is CS in Arduino?

In order to control which device is communicated with you also need a dedicated pin on your Arduino for each device, CS, which is connected to the SS pin on the device. When you set the CS pin for a given device LOW it goes into slave mode. The Arduino is also on the SPI bus and has its own SS pin.

What is the purpose of CS pin on memory component?

4- What is the purpose of CS and CE pin on memory ? These pins are used to select or enable device so that it can perform read or write operation.

Can you send data from one mkr1000 to the other?

I want to simply send data from one MKR1000 to the other over wifi, both are connected to the same network, but sending the data is where I get stuck, I’ve looked through tuts everywhere but can’t

How to use multiple select lines for SPI?

Use small rotary selector switches that encode a 4-bit value based upon the 0 -> 9 setting of the selector. Two of these can select addresses from 00 to 99. Have a setup mode in the slave where you interactively set the address and save it into non-volatile memory such as EEPROM or FLASH in the slave device.

Can a single SELECT line be used to select 3x slaves?

If you have two lines (in addition to MISO, MOSI, SCLK), you can connect them to a 2-to-4 decoder. That would allow you to select 3x slave devices (fourth one of the decoder outputs is for selecting none of the “payload” devices).

How are multiple SPI devices connected in parallel?

Have a setup mode in the slave where you interactively set the address and save it into non-volatile memory such as EEPROM or FLASH in the slave device. When you devise your SPI protocol set it up so every slave device is connected in parallel so all receive the SPI_SEL, SCLK and MOSI signals.
