SX/B commands in SX assembly

Wissam Ch.

Hi,
Is there a way to find the equivalent of any SX/B command in SX Assembly Language.
Iam looking particulary for SEROUT .
Iam working on a project and was using a set of 6 7-Segment LED display , iam shifting to LCD instead, and got stuck on how to send data to the LCD display using SX28 Assembly coding.

Regards

Wissam,

View the list file. Either use the hotkey "CTRL-L" or go to the menu "Run->View List".

Thanks,

Thanks Peter,
I am able to see the assembly equiv of the SX/B.
It is little bit scary , i think i should move to SX/B very soon and abandon SX Assembly.

I hoped to find an easy equiv for the SEROUT SX/B ....!!!!

No need to abandon assembly altogether, mix it into SX/B where appropriate. The program I've attached does buffered transmit and receive. I didn't write the assembly code for the UARTs, I just modified and folded it into my program -- it's easy to do with SX/B.

I found that interpreting SX/B listings in assembly were a bit daunting. You might look at examples of particular tasks from Guenther's text to get a better understanding.

For me, the problem is that SX/B abstracts the assembly code in a system that is without any comments. All the registers have generic names and it seems that I'd have to learn more than I want to know about how SX/B converts code to assembly.

JonnyMac is right - it is probably easiest just to mix the two as you find most convenient. Reading the CNTL-L listing is pretty demanding.

I managed to make my own implementation for the SEROUT SX/B command in Assembly .
the Listing helped me to capture the concept , and then i used my own coding in Assembly .
It worked and i can send data to the serial LCD from Parallax.

I think i will use both in parallel as you suggested , with focus on Assembly coding , i found it easier in debuging your own written code , than debuging in a complied SX/B code.

Thanks to all
