SXB compiler problem

RS_Jim

Good Morning All.

I have a problem with SXB. The following lines of code will compile OK:

··SHIFTIN·ADC_DIO,ADC_CLK,MSBPOST,tmpB1\9,4
··SHIFTOUT MEM_DO, mem_clk, MSBPRE, WRITE_M\5

This line of code returns···"error 4 pass 1 MSBPOST constant expected". I can change post back to pre and it will compile but as soon as I change the letters to post it will not compile. I am running V 1.51.03 of SXB.· After testing my code I reread the data sheet and decided that it probably was not working because of the pre/post issue so went to change my shiftout/shiftin commands to MSBPOST. The chip is a 93AA66 512 byte eeprom.

·SHIFTOUT MEM_DO, mem_clk, MSBPOST, WRITE_M\5
Any ideas?

Jim,
MSBPOST is not an option for SHIFTOUT.

The options for SHIFTOUT are LSBFIRST and MSBFIRST
The options of SHIFTIN are LSBPRE, LSBPOST, MSBPRE and MSBPOST

See the help file.

Bean.

Radio Shack Jim,

That's okay. Many of my days with programming and electronics are spent in similar situations. Combine programming, electronics, and anything else and you've got plenty of room for things to disagree.
