Product Number: MAX22200
Hi!
I am working on a project where we want to use the MAX22200 for controlling valves. The MAX22200 is being controlled over SPI from a stm32 board which works very well so far. Now I would like to add the possibility of controlling two MAX22200 chips with one microcontroller to have more valves. The datasheet of the MAX22200 says it is possible to daisy-chain but I am not quite sure how this is actually done since before every read or write operation needs a write to the command register prior to it and how chip 1 knows it is in a daisy-chain configuration and therefore puts the data for chip 2 on its DO line.
I'm looking for any kind of advice on this topic since I can't find enough info in the datasheet or elsewhere.
Regards,
Lars
