How many address locations does a 10 bit addressing scheme serve?
Address matching for 10-bit addressing is only up to two addresses.
How are 10 bit addresses sent on the SDA signal?
10-bit I2C Addressing If the master will read data from the slave device it must send the complete 10-bit address (two bytes) as for writing, then a repeated start is sent followed by the first address byte with read/write bit set to high to signal reading.
What is better 8-bit or 16 bit?
In terms of color, an 8-bit image can hold 16,000,000 colors, whereas a 16-bit image can hold 28,000,000,000. Note that you can’t just open an 8-bit image in Photoshop and convert it to 16-bit. This extra bit depth does come at a cost. More bits means bigger file sizes, making images more costly to process and store.
Where are the 10 bits in I2C slave addressing?
The 10 bits of the address is encoded in the last 2 bits of the first byte and the entire 8 bits of the second byte. The 8th bit of the first byte remains the read/write flag. If a 10-bit address is specified when using the Aardvark I2C/SPI Host Adapter, its software will take care of sending the correct bits.
Can a 10 bit address be used with a 7 bit address?
10-bit addressing can be used together with 7-bit addressing since a special 7-bit address (1111 0XX) is used to signal 10-bit I2C address.
How can I tell if my slave address is 7 bit or 8 bit?
Another way to determine if a vendor is using 8-bit addresses instead of 7-bit addresses is to see if the slave address falls within the correct range. All 7-bit addresses should be greater than 0x07 and less than 0x78 (120). If your slave address is outside this range, chances are your vendor has specified an 8-bit address.
How many addresses are there in the I2C specification?
The I2C specification has reserved two sets of eight addresses, 1111XXX and 0000XXX. These addresses are used for special purposes. The following table has been taken from the I2C Specifications (2000). (1) No device is allowed to acknowledge at the reception of the START byte.
