AFE4490SPO2EVM communication protocol

Other Parts Discussed in Thread: AFE4490SPO2EVM

Hi,

I am using Matlab to read data from the AFE4490SPO2 EVM. Using the communication protocol version 3. I am writing 0x01 0x2A 0x30 0x30 0x38 0x00 0x0D to the board to capture 2048 packets. However I am capturing more than 1024 packets of data when I do this. Using a serial port monitor program to monitor the write and reads during the use of the AFE4490SPO2EVM GUI, I noticed that the start read register command is different to that described in the communication protocol and is 0x01 0x2A 0x30 0x30 0x30 0x30 0x30 0x38 0x30 0x30 0x0D. However using this command in my code I am still reading more than 2048 packets. Am I misunderstanding something and which is the correct command?

Cheers,

Cat
