Re: [ts-7000] SPI interface to additional device/EEPROM

[anand bhavnani <>]

Hi All,

 

using a DIO as chip select is ok,

but then i need to ensure that the EE_CS for the eeprom and the additional DIO chip select for my DAC are time multiplexed as they select the respect ics...

for this i would need to continuously monitor the EE_CS and select my DAC using DIO accordingly..

now how do to do it..

i even don't know what does the EEPROM do and when is it active...

please tell me the functionality of the EEPROM and how to take care of DIO and EE_CS

 

Good bye,

anand.

Use a DIO pin as your chip select...
