Prop 2 Instructions
Have the new instructions for the Prop 2 been finalized? I looked at the Wiki, and read the discussion about new instructions that could be added, but it’s not clear whether they have all been accepted. From what I can tell the new instructions would be:
Code:

Like others I hate the new layout of the instructions manual so I use the old one. Today I had a look at the new version (7/10) and that one has added XCH and other functions (take a look at the change list) but I can't find any AVR's with the instructions! Does anyone have some info?The instructions for making v1.1 of the stepper driver board contain what I believe is a minor error. The instructions are at [reprap.org] I attempted to edit the page, but I was asked me for a password and I don't believe I have a wiki password. The error is in the instruction to place C7, the 3.3nF cap: "Solder it into place next to the trimpot." The cap next to the trimpot is actually C6 (100nF). This isn't horribly misleading in that C6 is placed before C7, but it gave me a moment's pause as I had to reconcile the ...On the Mega8 (and others) is there any advantage to using the specific instructions to set/clr individual SREG bits? Since BSET and BCLR can be used to accomplish the same thing as instructions like SEN and CLN, it seems redundant or wasteful to have specific instructions to handle individual bits when there is already general instructions to do so. I say wasteful because several people have complained that there is no ADDI instruction, and the argument was that there was no room left in the instruction map. The instructions used to set and clear SREG bits would have freed up ...Hi, Im trying to optimise some of my code because its not running fast enough. Im trying to control PWM seperately on 24 pins. I did some tests to see what was taking so long and it seems to be the if statements. Code: IF 1=vPWMPos THEN ENDIF 'Where vPWMPos is 1 the above code takes 7 instructions 'Where vPWMPos is not 1 the above code takes 8 instructions 'I also found out that the compiler does some clever optimisation IF 1=1 THEN ENDIF 'The above code uses no instructions at all because the compiler realises 1 will always equal 1 So, 7-8 instructions just for an if statement seems ...For eeprom writing following instructions are required. But these instructions do not work in AVR Studio4 EECR |= (1ltltEEMWE); EECR |= (1ltltEEWE); on the other hand if the instructions are written in assembly amp put in C code the code works fine what could be the possible reason?Hi all, I have the MK158 Kit and in the instructions is a diagram that shows the location of the serial interface next to the 9V connection on Step 15 (Final assembly). It appears to have space for 2 wires. It says to look on velleman.be for a how-to, but I can't find it, only the same instructions that I have. So could someone here explain to me which pins on a RS-232 connector I need to connect to what on the board? Or point me to some instructions. Thanks a lot, AlanHey guys, Am taking the self source route and have my boards etc from ladyada, but i didn't get any instructions. I have the scematic but they only refer to r3, r15 etc with no reference to the components and values....Where do i get full build instructions??? Please help me....I may be retarded.. Cheers!Hi friends As I know, we should use STS and LDS instructions to access SRAM ( Direct read and direct write ). but these instructions are 2 word instructions and i think two word instructions is not so nice to access Ram, is there any better way to read and write to SRAM registers? ( with 1 word upcode ) RegardsIn my assembler code, MPLAB dosn't recognize some instructions such as rrf, rlf, clrc, skpnc and a few others. It color codes them like labels and also gives build errors. I am using a 16F690. When I import the same code file into MPLAB-X it recognizes the instructions. Also, I previously ran part of this code with the same instructions in MPLAB 8.84 and it ran OK. I tried the MPLAB Help but couldn't find any answers. JackHi, All is there any guide(link,book). which tells about complexity of instructions we use in microcontroller's programming in c language e.g switch() is better or if statement. I know it mostly depends upon compiler we are using. but any general help. to make program most efficient fast for execution, with best choice of instructions like if(SW) is better than if(SW==1) Thanks in advance .YatoofHello everyone, I have project to make a c/c program acts like MIPS assembler, in other words I have to implement ISA using software. To make it clear, the user write a .txt file including some MIPS instructions (e.g "ADD $t9,$a0,$t5"), and I should read instructions and perform execute it on registers (variables in my program), My main problem in branch and jump instructions. Also I did the scanner, where I put all the user file in an array, but I am thinking to change this to take one instruction at a time (one line). One last thing, the memory ...FYI! This is for a school project. I just need some guidance as my instructor seems uninterested. I have to write some code for the Z80 that will execute two instructions then copy those instructions to 2000H then goto 2000H and execute those instructions there then return to the original program and delete the instructions that were copied to 2000H Here is what we start with: Code: ORG 1800H ADD A,B ADD A,C NOP NOP NOP NOP NOP NOP NOP NOP NOP NOP NOP NOP HALT Select All I have to replace the NOP's with the new instructions. Here is where I am: Code: ORG 1800H ADD A,B ADD A,C LD A,(1800H) LD (2000H),A ...Hello.Would you please tell me what are the meanings of the following instructions; x1=ADC-read(0)-23; x2=ADC-read(0)-2; I mean why subtract; 2 or 23 from adc instructions at above;what does it mean? Thanks,succesfully built 1 gps sheild from instructions given on internet, my second kit is different it has a with a chip hat gets soldered to the board my first kit did not have a chip.... does any one know where instructions and downloads are for this new or old kit????? the kit says GPS log shield kit v1.1Prop Tool says there's no chip can be found- is that because I don't have an external 5V power supply to it? (I bought the Quickstart board and it didn't need one.) I don't have any that fit, do I have to buy one, or is it broken? I downloaded the schematic pdf but there are no instructions to get it to work. BTW, in order to intergrate these 3.3v boards with TTL logic, I'm going to have to create some kind of buffer, right? Drive a transistor into saturation to bring it up to 5v. Is that what other people do? ...I would like to find out, *without* opening the assembly listing, the number of instructions for a line ( or a number of lines ) in CCS C. Is this possible ( even in conjuction with tools like MPLAB using the plugin )? For example, 1. I want to find out how many instructions Code: delay_us(200); generates 2. I want to find out how many instructions Code: set_timer1(0); delay_us(200); generates 3. Then, I would like to count the number of clock cycles it took to execute each function, *without* opening the assembly listing---------------------------------------------------------------------- I want to calculate MIPS or instruction number with my code based on C language. If I know number of instructions, then I can calculate MIPS with instruction set cycles. So I've tryed with silicon lab IDE tool(debug window). I can check the diassembled code, but how can I get to know the number of instructions,,? Is there any idea to calculate MIPS?? IP: Logged vanmierlo Member posted February 09, 2010 06:13 AM ---------------------------------------------------------------------- MIPS (mega instructions per second) depends on your SYSCLK, chosen MCU, external memory interface setting ...Is there any list available for each AVR feature and instructions when overclocking? By watching this video the AVR (ATmega8) pins can be overclocked to 51MHz. http://www.youtube.com/watch?v=gje4SvGOFuQ E.g. If a program/system need to do lots of calculations this overclocking (on certain parts in the program) would save a lot of time. Anyone tested instructions on high speeds?I desperately want to update my x0x with the Sokkos firmware, but try as I might, I cannot figure out how to do this. I have followed the bootloading instructions both for the Mac and the PC, and I can't seem to get it to work. On the Mac, the RXTX package won't install (the installer requires all sorts of Terminal commands that turn out to be invalid...I think), and on PC the the instructions for CommAPI just don't add up. What have others done? I can't imagine that everyone who has updated their firmware is a Java expert, so ...Hi, I'm trying to read from a digipicco I2C humidity sensor, so I'm using the Wire library, but when my code arrives to several instructions it blocks the program. This instructions are "endTransmission" and "requestFrom". So, my question is: Do I have to do any special thing?? (like switching off the uarts while I read the data). Thanks.
