Hi,

 

I am working with BF527 hardware.

 

Is there any read APIs which satisfies the below kind of read format with Master acknowledgement.

 

I checked the linux kernel documentation for smbus protocol. I could not find any. which twi apis will support this kind of format?

 

AS - Slave acknowledgement

 

AM - Master acknowledgement

 

read format 1:

S    Addr   Wr   AS   RegH   AS   RegL   AS   S  Addr Rd    AS    DATA1   AM    DATA2    AM ...........    P

 

read format 2:

 

S    Addr   Wr   AS   DATA1    AM   DATA2    P               

 

Thankyou.

Dear Robin,

 

I have checked the AD5252 code in the kernel. the read format for the AD5252 device is different to what i have asked for the read format above.  so could you provide some more details on this.

 

Thankyou.
