Some doubts about which version to choose

[Juan Gonzalez]

Hello. First, thanks a lot for such an impressive work in a fascinating project. I am trying to decide on which version to choose, and there are a couple of things I don't quite understand:
1. I aim to DRV8825HW203 and I rather prefer OLED display, but think that probably the best way to move the focuser will be the IR controller,provided that doing it with buttons might be too slow. It seems both options are not available at the same time, as the "pcb options table" says M-MT-F-BT has OLED but not IR and FIRBT has IR but not OLED, only LCD. Am I right? I don't quite see this as both LCD and OLE goes as I2C...
2. Now I have a C8 f/10 tube, but I could be moving to a Esprit 120 refractor (f7) in the near future. I would like to build a focuser that will fit the new tube, but as I dont have it yet I can't measure the "distance per one revolution"... Is there anything I can do?

Best regards
Juan

Hi Juan
for the DRV8825HW203_FIRBT board
The firmware file is
myFP2_DRV8825HW203_304,ino

Yoy can enable the OLED display in focuserconfig.h by
// To enable the OLED DISPLAY uncomment the next line
#define OLEDDISPLAY 1

and enable the IR Remote by

// To enable an Infra-red Remote, uncomment the next line (only available on some boards)
#define INFRARED 1

and then program the controller.

I dont have any values for an Esprit 120 refractor. However, I would of course recommend the DRV8825 board - which will work with a different NEMA motor.

Its probable you would consider using a NEMA 14 0.9degree stepper motor for the C8, then you can use the same controller on the esprit later by using a NEMA-PG15 or PG27 motor.

Hi. Thanks for the quick reply, I therefore understand that IR and Oled are posible at the same time with FIRBT Pcb, even though the PDF does not says so in the table of the diferent versiones of Pcb offer. (page 33)
What about BT and IR? The pdf says they are not compatible. I suppose that means that I can mount both options and use one option or the other but not mixing the two at the same time. Am I right? Otherwise why putting both on thje same PCB...
I just want to make my mind on the way I am going to work with it.
Cheers

The firmware for the board supports oled or lcd

What about BT and IR? The pdf says they are not compatible. I suppose that means that I can mount both options and use one option or the other but not mixing the two at the same time. Am I right?
No, not really/
The BT and IR need to use specific pins, - in this case the same pins, so its one or the other. Same pins, different hardware. Cannot be shared

If you wanted the Wifi and IR etc all together then you are better off looking at the myFP2ESP controller.
