31Dec2016 New v251 firmware for ULN2003 and L298N drivers. There was an error trying to compile with the Home Position code enabled - now fixed.
Beware - if you are not using the Home Position switch - in other words a switch has not be wired, then check this line in the code to ensure that it is commented out (the // in front at the start of the line must be in place!!! )
// #define HOMEPOSITIONSWITCH 1

04Jan2017 Have added an L298N Full option , schematic and board layout (I was testing the new v253 code for the L298N and needed an LCD to check values so now there is a Full option with push-buttons and LCD (both 1602-I2C and 2004-I2C support).

06Jan2017 Minor correction to L298N - the 12V power connection on some boards from ebay/china is different. Have updated pdf document and associated jpg. For the 12V/GND/5V connection, the labels are either on the top side of the board or underneath. In some cases the 12V/5V location is swapped. Recommend that you check the purchased driver board for the correct orientation.
Have added another simple guide - for the L298N Minimal as this is a very popular choice.
Cheers
Robert
On a side not, I have tried connecting the 12V to the 5V pin and the driver board still worked. I would not recommend that long term though.

09-Jan-2017 New PDF, New ASCOM drivers, New Windows App, New Windows Mini App.
ATTENTION
In beta testing with the 253 firmware, it was found that when using ASCOM Driver or Windows App, then disconnecting from a controller, the controller could sometimes go into an indetermine state after disconnection where the controller was no longer functioning correctly. When connected to a driver/app the controller was fine.
In testing, all previous firmware/driver/apps has this issue, at least going back some time.
This latest release addresses this long standing (but previously unreported) issue. Please update to latest firmware/Windows App/ASCOM drivers.
The Wifi firmware, Wifi ASCOM driver and Wifi App is not affected.
Regards
Robert
To confirm - this issue only occurs when you have been connected to a myFocuserPro2 controller and then disconnect. If at that point you wanted the focuser to continue operating by itself, the potential exists for the controller to enter an indeterminate state and function incorrectly (the focuser no longer moved, no longer updated the LCD, and no longer responded to RE/IR/Push buttons)
Issue is resolved with this release.

16 Feb 2017 I have updated the miniApp for Windows with a number of newer features. One can now set the maxSteps. maxium focuser position. I have added the Go buttons/commands to all the focuser presets as well as fixing the bug in the focuser position not updating during a move. The pdf has been updated with the latest screenshots for the miniApp

7th March 2017. New ASCOM drivers v241. New ASCOM Tester APP v1302. New Windows app v2365. New PDF documentation v274. These changes reflect the addition of a new checkbox on the ASCOM drivers to enable/disable temperature compensation when connecting to a myFocuserPro2 controller. The new Windows app adds the ability to set a warning pop-up message whenever the user clicks the SET position button for maxsteps and focuser position.

10 March 2017. L293D Mini driver board finally arrived today so all the final versions of the schematics and arduino code has been uploaded today. It is good to go.

14 March 2017: Major firmware update to L293DMini, L298N - these boards now support both FULL and HALF stepping. All related PDF's updated. There are two other support files to do the half stepping and these must be in the same folder as the arduino firmware file.
So if any of you have implemented the L298N you can now load the new firmware and use the new half step mode to get double the number of steps and better resolution.
Am still experimenting with the speed settings for half stepping mode but I believe the code is good to go.
Cheers
