TSV2HEX

Tiny Free Pascal Program for dumping a TSV ASCII Truth Table to Intel .HEX file

(C) 2021 David Collins Released under the MIT Licence

This is Beta 1.0 of my simple program for converting a TSV (Tab Separated Values) ASCII file to a Intel .HEX file. This is usefull if you need to make a simple combined logic replacement with an eeprom.

You can easily build a truth table by building a design in logisim and then copy and pasting the truth table from logisim to a text file.

so far it works if you leave the lables on the top, inputs on the left, outputs on the right. the inputs 1's place is the right most bit defined by the inputs variable (in the case of the example it is d). The outputs 1's place is the right most bit as defined by the outputs variable (in the case of the example it is z).

here is an example file: <PRE> a b c d w x y z 0 0 0 0 0 0 0 0 0 0 0 1 0 0 0 1 0 0 1 0 0 0 1 0 0 0 1 1 0 0 1 1 0 1 0 0 0 1 0 0 0 1 0 1 0 1 0 1 0 1 1 0 0 1 1 0 0 1 1 1 0 1 1 1 1 0 0 0 1 0 0 0 1 0 0 1 1 0 0 1 1 0 1 0 1 0 1 0 1 0 1 1 1 0 1 1 1 1 0 0 1 1 0 0 1 1 0 1 1 1 0 1 1 1 1 0 1 1 1 0 1 1 1 1 1 1 1 1 </PRE> make shure there are no trailing spaces at the end of the file, these can cause issues. you can run the program from a shell (win32 binary is included, working on building on linux but this was built in lazerus so it 'should' just build if you want to try it your self on linux or OSX.)

you can run by typing: <pre> TSV2HEX [arguments] </pre>

The arguments and paramiters need to be seprated by spaces, it will produce an error if you try to enter more than 8 arguments. the current supported commands are: <PRE> INP [Argument] : Example INP 4 sets the number of inputs to 4 OTP [Argument] : Example OUP 4 sets the number of outputs to 4 OFN [Argument] : Example OFN <filename> sets output filename IFN [Argument] : Example IFN <filename> sets input filename

try : TSV2HEX INP 4 OTP 4 OFN out.hex INF test.txt

with the test.txt file it should produce a OUT.HEX with the following first line: :10000000000102030405060708090A0B0C0D0E0F78 :1000100000000000000000000000000000000000E0 ... {more or less the same until} :107FD00000000000000000000000000000000000A1 :107FE0000000000000000000000000000000000091 :107FF0000000000000000000000000000000000081 :00000001FF </PRE>

if you are missing an argument or two or enter none, it will drop you to a ":" prompt. from here you can type HELP or QUIT to continue.
