P2 Test Toolbox

ozpropdev · 2014-03-12 04:56

Hi All

This is a program I have been using to test P2 instructions and debug code snippets.
It runs via a serial terminal on both DE0-Nano and DE2-115 FPGA boards.
Program has logging and trace facilities and allows live modification of instruction D,S values.
Hub and Cog memory view functions and assorted functions to manipulate D,S registers.
The Z and C flags can be overridden too.

P2 Test Toolbox v1.4.spin includes a test of the logger already setup, use "M" to test.
Four additional test examples are included as well.
TEST1.spin Tests a DJNZ loop.
TEST2.spin Tests a delayed DJNZD loop.
TEST3.spin Tests a REPS loop.
TEST4.spin Tests the DJNZ loop with 2 additional hardware task running.

Once loaded use the "M" command to run the above tests.

P2 Test Toolbox V1.4

To start Toolbox press "*".

Toolbox displays the following format response.

Brian,

This look very helpful and will be lots of fun to play with!

Please feel free to push it up to the P2 Testing Repository on GitHub. There's a "tools" directory it would feel right at home in!

Thanks!

Cluso99 · 2014-03-12 15:52

Brian,
A very useful tool!
BTW Don't worry about decoding the instructions back to pasm source. I have done that with my P2 Debugger and just need to update it to the new instruction set. When I have it done, you can copy that section into your code - save your time for some more useful features

Sounds good Ray!

I was just looking at the new instruction encoding.

Hi All
Here is an update to P2 Test Toolbox.
I fixed a couple of things and updated the docs (typos).
I added text dump of hub memory.
I also enhanced the TRACE report a bit to make it a bit easier to absorb.

re: P2 Test Toolbox[/h]
Great!! idea. I'll check it out. Thanks!!

mindrobots · 2014-03-14 12:17

Great stuff, Brian!

Thanks for putting it in the GitHub repository!

CHEAP PLUG: Don't forget, if you want to play along in the P2 FPGA testing, sign up for the GitHub Repository!

ozpropdev · 2014-03-15 05:44

OOPS!

In the "execute" section the following code needs to be modified.

:loop			popzc	zc_flags
with
:loop			popzc	zc_flags [b]wz,wc[/b]

Sorry Guys!

I've added some more features, I'll post an update soon.
Cheers
Brian

ozpropdev · 2014-03-22 05:08

Hi All,
Here is the latest upgrade Version 1.8 for the new FPGA release (20th March 2014).
Some new commands have been added. See Docs in zip file for more details.
Cheers
Brian

Post Edit: To start Toolbox use Backspace now not * like the previous versions.
I'm putting together some more demo's of all the features. I'll post them soon.

Cluso99 · 2014-03-22 06:08

Nicejob Brian. Cannot look/check till Monday.

ozpropdev · 2014-03-30 04:28

Hi All
Here's the latest update of P2 Test Toolbox.
See docs for changes.
