NOTE: Notepad users will have to select ALL file types and then make the filename "Class7. Now that we have a good ASM file (if you followed instructions that is), now you want to save that text file as Class7.asm Which is not concurrent with the last address that was used (2B2Bh), so we will need to put a blank line and another org for it so put in a blank line andĪnd you should know what to do with the rest of the line by now delete the address and the hex value right behind the address since they are NOT needed which leaves us with this:ĢB29: D508 clr 08h <-now do the same for this lineĢB2B: 8C3C18 br 3C18h <-and do the same for this line also The address is concurrent with the one before it and no address is skipped (left blank) so we can delete that and the HEX values that are right after it which leaves us with this:Īgain. Which IS what HUASM needs to assemble that line properly so put that on Those in for us which leaves us with this: The hex values at the beginning are not needed because HUASM will fill We already did the org for address 2B20h so the address is NOT needed

Now the next line, we need to strip out everything that is NOT needed in the ASM file (because it makes it easier to read then and makes it neater) then put: The starting address is 2B20h so put a blank line under the db 025h,0DAh Now these addresses are all concurrent which means that no addressesĪre skipped in this section which means that you will only need 1 org for this section Lets move onto the next section of the ASM Remember to only use the ORG when addresses are NOT concurrent (meaning that no addresses are skipped) It also includes a declaration of the length of the array. You can dump that into a file to be included, and then just access foo like any other character array (or link it in). So now you first two lines should look like this: A complete static array definition is written (named after the input file), unless xxd reads from stdin. The bytes that we are going to be writing to address 2014 do notĭisassemble because they belong to the FUSE BYTES so they are calledĭATA Bytes which are done in ASM like this: Org = Starting address that the bytes to follow will be written toĢ014h = The address to start writing those bytes to To state starting addresses in ASM format you will use org so for the first line in a new notepad (or whatever text editor that you use) it will look like this: I am providing a manual method for finding assembly code from hex code, may it help you out.Īnd here is what it look like disassembled from the hex file: : Any tool available or any trcick to implement that.

: Is it poosible to convert hex 8051 compiled code back to C code.
