Is that possible and If It is, how to turn it on. Jim Jim Wagner Oregon Research Electronics, Consulting Div. and this kind of error will never occur. http://www.avrfreaks.net/forum/invalid-register-error-w-attiny2313-r0-r15 You probably want STS as per section 5 of the Mega168 data sheet.
The usual way to set that is to ldi the value (0x04) into a temporary AVR register (like R24 perhaps?) then use out to write this to SPL.

A register can have several symbolic names attached to it.
Each expression must evaluate to a number between -128 and 255. http://www.atmel.com/webdoc/avrassembler/avrassembler.wb_Known_Issues.html r1) as the argument. –Jester Mar 8 '14 at 23:21 Yeah that sounds like what I'm trying to figure out. An EEPROM segment will normally only consist of DB and DW directives (and labels). avrfreaks does not support Opera.
If the expression evaluates to a negative number, the 8 bits twos complement of the number will be placed in the program memory or EEPROM memory location.If the DB directive is http://objectdevcorp.com/avr-studio/avr-studio-4-error-127.html The DB directive must be placed in a Code Segment or an EEPROM Segment.The expression list is a sequence of expressions, delimited by commas.

The difference between the two forms is that the first searches the current directory first, the second does not.
In order to be able to refer to the reserved locations, the DB directive should be preceded by a label. Vivid examples demonstrate the applications of each peripheral function, which are programmed using both the assembly and C languages.Important Notice: Media content referenced within the product description or the product text Mar 14, 2012 Posts: 27 View posts #7 Posted by naturephoenix: Thu. navigate here Useful in conditional assembly.
A data segment will normally only consist of BYTE directives (and labels). Log in or register to post comments Top jgmdesign Level: Moderator Joined: Mon. I have a problem with AVR Studio 4 not compiling my code.
Mar 15, 2012 - 05:51 PM 12345Total votes: 0 The destination operand stands on the left side and the source operand on the ricght. This prevents DEFINED(symbol) to be used as a user symbol like a label, etc. Note that the preprocessor and assembler have separate implementations of DEFINED(symbol). more stack exchange communities company blog Stack Exchange Inbox Reputation and Badges sign up log in tour help Tour Start here for a quick overview of the site Help Center Detailed
I'm trying to do something like this: ; accepts 1 argument: target register. .macro move_r10_into mov @0, r10 .endmacro ; usage example: move_r10_into 1 ; So this should do mov r1, OUT only works if the address you're transferring to is less then 63, and TWCR has an address of 0xBC. You probably want STS as per section 5 of the Mega168 data sheet. his comment is here A symbol can be redefined later in the program.

Also, as Jim noted it appears you are trying to load a 16bit address in an 8 bit register. Actually I'm trying to clear some of "working registers", -> (R0-R29) This is the code: #include "m16def.inc" clr ZL clr ZH Loop: st ZH,Z inc ZL cpi ZL,30 brne Loop I

Example:.org LARGEBOOTSTART ; the following sets up RAMPZ:Z to point to a FLASH data object, typically ; for use with ELPM. It gives me an "invalid register" error for every line of code in my asm-file.
An Assembler file can consist of several Code Segments, which are concatenated into one Code Segment when assembled. This label can then be used in later expressions. defined incorrectly treated as an assembler keywordThe keyword DEFINED(symbol) is recognized in all contexts, it should only be recognized in conditionals.
