A basic python script to export Atmel Studio stimul files (*.stim) to column data files (to plot) (Not fully tested)
I am a very beginner in python but this script does its job... It may be used to generate plots from stimuli files. For exemple, here is an example of stimuli datas:
#163492
DDRB = 0x02
#9199
DDRD = 0x10
#588
DDRD = 0x00
(...)
Running the script with the following options:
python Stimuli_export.py mystimulifile.stim -f DDRD -f DDRB -f PORTD -f PORTB -m 0xFF -i 0 -b -e -s 0
with:
- "-f": specify the registers to export
- "-m": a bit mask to select which bit to export. (may be different for each register)
- "-i": the initial value of register (may be different for each register)
- "-b": value are exported in a binary format "0b00011010". Specify "-x" instead to use a hexadecimal format.
- "-e": with "-b" options, it "explodes" the byte in 8 columns, so that a column is generated for each bit
- "-s": start export at time (clock) 0
A file is generated for each register. In this example, 4 files are created:
- "mystimulifile_DDRD.stim"
- "mystimulifile_DDRB.stim"
- "mystimulifile_PORTD.stim"
- "mystimulifile_PORTB.stim"
The output file <mystimulifile_DDRD.stim> would be for example:
# cpu time b7 b6 b5 b4 b3 b2 b1 b0
000000 0 0 0 0 0 0 0 0
009198 0 0 0 0 0 0 0 0
009199 0 0 0 1 0 0 0 0
009786 0 0 0 1 0 0 0 0
009787 0 0 0 0 0 0 0 0
010237 0 0 0 0 0 0 0 0
010238 0 0 0 1 0 0 0 0
010241 0 0 0 1 0 0 0 0
(...)
With Octave, matlab, gnuplot, etc it is straightfoward to get something like this:
