MSP-GANG: Questions for command usage

Hello,

I'll need a few days to dig into this and get back to you.

Hello,

Thanks for your patience.

Q1) What does byte 7(Ack or Nack) mean in data received by “Get Progress Status” command?
I thought byte 6 shows Status of previous command. Is this same as byte 7 ?

I've learned that there are two different communication protocols that the MSP-GANG can use:

• UART communication – Refer to page 69 in MSP-GANG user's guide
• DLL (USB) communication – Refer to page 117 in MSP-GANG user's guide

For the MSPGANG_GetProgressStatus() function, the data bytes are offset by 2 bytes between the UART and DLL functions. The definitions/descriptions in the user's guide for most bytes can be cross-correlated between the functions on page 69 and 117. However, the descriptions for UART bytes 6 and 7 and the DLL bytes 4 and 5 don't really match, but the bytes are used in the same way. I've added some more details for these bytes in the Description column.

Q2) Suppose there are a few image files and “Select Image” command is used to select one of them.
Is there a command to confirm which number is currently selected?
Whenever ACK is received by “Select Image” command, no need to warry about it?

I couldn't find a command that does this. Rather than sending a command to check on the selected image, I would just (re)send the command to select the desired image.

Hope this helps.

Hi James,

For Q1, it is still not clear for me what does the byte 7 exactly mean.
"Global status from start to current time"
- What is "Global status"?
- What does "start" mean? start from what?

Thanks and regards,
