Request sample Hex vi

[Kabo]

Hi !

I'm a frequent 7.1 LabView user. Just want to request vi that can write hex message like for example "0xAA" to acertain address "0x00" then read.

The read hex message should also be "0xAA".

It sounds like you just need to use the In Port and Out Port functions on the Advanced Port I/O palette.

Dennis,

Thank you for your information, I am planning to use the sample basic serial vi but I don't know how can I start with it.

It's my first time to make this program but I don't know how can I send that hex message on a particular address?

Do you have actual sample for this ? Can I request ?

Thanks,

Gilbert

Hi,

I'm sorry, but I do not understand what you would like to do. Do you want to transfer data over the serial port? Please explain your problem a bit further!

Hi Mathias,

Sorry for the confusions. Yes, I have to transfer data over the serial port. To make it clear for you, the instruction is like this "Write 0x55 to address 0x1000 then read. If the byte read is 0x55, proceed to the next step. Otherwise, send message to the PC "Flash test fail" then abort Flash test".  Sending message "Flash test fail" to the PC will be very easy for me as long as I read it correctly.

Hi,

we'd need a more complete specification of the protocol you have to implement.

Data on a serial port / serial line is just a stream of bytes. There is no fixed convention of how to "write data to an address". This depends on the device you want to talk to.
