And then the price should be equal, not less... but it's your money. Do please let us know how that wise penny works out.

Hello I am again,
While working at 5 phase microstepping, finally my 2 phase bipolar driver has been finished.

There is some feature about my driver :
- half and full step mode
- up to 3 A / phase-- I use parallel of L298
- current limiter : on steady, the current has limited to 1 A, so L298 is safe.
- Unipolar can use this driver, with some modification wiring.


This board is same as board that i used in 5 phase driver. but I change the position PIN of INHIBIT of L298.

So enjoy this driver in here :

Great! Any clue on what language that is so we can try to translate it? What does it cost?

[nastelroy]

there is Indonesian language (Bahasa).
It is cheaply if you made by yourself, about 50 USD with aluminium case.
i think the most costly part is the PCB.
Hard to find cheaply PCB manufacturer in here.

Did you follow his instructions? It is not a zip file.

"Also take a look on my experiment. Rename my_experiment.txt to .c and Bipolar_sim_2.zip to Bipolar_sim_2.DSN. The DSN is the Proteus simulation file. Compile my_experiment.c using CCS and add the HEX for the sim to work."
