Hello
does anyone have an idea of the commands that Pyxis sends to the rotator and the denomination.
This would be to create arduino code that works with this driver, of course this is possible.
Thank you very much for your help.

hello Jasem
I have a question, would it not be easier to take the Pyxis driver which is only for a rotator and adapt the arduino code of the nightcrawler to the Pyxis driver or is it not possible?
Unless I find the Pyxis arduino code, but for the moment I haven't found anything.
See you soon

hello
so this is where I need to edit
################ NightCrawler Focusing Rotator ################
SET(nightcrawler_SRC
${CMAKE_CURRENT_SOURCE_DIR}/drivers/rotator/nightcrawler.cpp) !!! here only ? !!!
add_executable(indi_nightcrawler_focus ${nightcrawler_SRC})
target_link_libraries(indi_nightcrawler_focus indidriver)
install(TARGETS indi_nightcrawler_focus RUNTIME DESTINATION bin)
I have just taken QTCreator, it seems to me much more complex to use, I will look at it and try to understand its functioning

ok
so I'm copying and changing the names here for me
/home/christophe/Projects/indi/drivers/rotator
and the new file I can call "mynightcrawler" in h. and cpp.
but i can't find the way to get there
INDI CMakelists.txt
I'm sorry again for my ignorance on the subject

sorry again,
but I didn't quite understand that
**
You can rename the source files, and then look for nightcrawel in CMakeLists.txt and just copy the section for it and rename everything accordingly.
**
what should I do?
I just have to find the files, copy them, modify and rename them ?
or do I have to make a new driver by modifying the original files ?

hello Jasem
so I'll try to modify the driver and remove the parts that I think are useless.
But where can I see the commands in the driver, that it sends to the arduino, because I need to find the "home" command of the rotator, and the command to give an angle from the serial terminal of the IDE, to control the modicication of the code without going through kstars for my tests.
And thank you for the link to the other rotator drivers, but is there also one online for the arduino.
Thanks again.

Hello
One more question Jasem, how do I rename the driver that I modify so that I still have the original.
How do I install the modified driver and with which file do I have to do it?
Thanks again.

Hello Jasem
then this is my problem, I'm really not expert in indi code, but if I look at the nightcrawler.h code there is a lot of parts I could remove, I think, that have nothing to do with the rotator, like ...
// Focus Sync
IUFillNumber(&SyncFocusN[0], "FOCUS_SYNC_OFFSET", "Ticks", "%.f", 0, 100000., 0., 0.);
IUFillNumberVector(&SyncFocusNP, SyncFocusN, 1, getDeviceName(), "FOCUS_SYNC", "Sync", MAIN_CONTROL_TAB, IP_RW, 0,
IPS_IDLE );
// Voltage
IUFillNumber(&VoltageN[0], "VALUE", "Value (v)", "%.2f", 0, 30., 1., 0.);
IUFillNumberVector(&VoltageNP, VoltageN, 1, getDeviceName(), "Voltage", "Voltage", MAIN_CONTROL_TAB, IP_RO, 0, IPS_IDLE );
// Temperature
IUFillNumber(&TemperatureN[0], "TEMPERATURE", "Value (C)", "%.2f", -100, 100., 1., 0.);
IUFillNumberVector(&TemperatureNP, TemperatureN, 1, getDeviceName(), "FOCUS_TEMPERATURE", "Temperature", MAIN_CONTROL_TAB,
IP_RO, 0, IPS_IDLE );
// Temperature offset
IUFillNumber(&TemperatureOffsetN[0], "OFFSET", "Offset", "%.2f", -15, 15., 1., 0.);
IUFillNumberVector(&TemperatureOffsetNP, TemperatureOffsetN, 1, getDeviceName(), "TEMPERATURE_OFFSET", "Temperature",
MAIN_CONTROL_TAB, IP_WO, 0, IPS_IDLE );
// Motor Step Delay
IUFillNumber(&FocusStepDelayN[0], "FOCUS_STEP", "Value", "%.f", 7, 100., 1., 7.);
IUFillNumberVector(&FocusStepDelayNP, FocusStepDelayN, 1, getDeviceName(), "FOCUS_STEP_DELAY", "Step Rate", SETTINGS_TAB,
IP_RW, 0, IPS_IDLE );
On the other hand I can't find the function that kstars sends to the arduino to tell it to do the GoHome
I'm not sure if you have the time to do it, but I'm sure you can figure out how to do it, so I'm not sure if you have the time.
Thanks again

Hello
So, indeed I would like to adapt an arduino code for this driver.
I already have the one for the driver, but it is too complicated because it is also for a focuser, so I would like to try to make a simpler one.
And my second question is to know if there is a way to modify the nightcrawler driver to make a simpler one, just for a rotator.
Like for example:
I would just need in the configurations, the "HOME" with the position that we want (from 0 to 360 °) to choose.
And to be able to do it either by pressing a button, or, automatically at the beginning of its use.
I don't know if it's possible
See you soon
Christophe

Well, I guess I'm not having much luck right now.
I'm waiting for someone to explain to me or to tell me that it's not possible either to modify the display of the driver in kstars or to know the commands and the returns that the driver sends.
see you soon

helloafter opening a topic to make a rotator, because although I can make the driver work with my project, I need information about this driver.First thing, how can I find the commands that the driver sends to the rotator.because I can't make the "GoHome" work and I would like to simulate it live in the arduino terminal to check if I have the right output and if the command is good.The second thing is that it is possible to remove the part that is used for the focus in the tab of kstars and in the arduino code, or it is a problem?
Thank you

Hello
can you tell me where is the file of a driver in kstars,
because I would like to find which command it sends to the arduino and if it's possible to modify the layout (for a better translation in french).
Thanks a lot

Hi,
I've managed to get the code to work with the TB6612, but I don't know if I have all the functions.
I have a question when you select a rotator, can you control the orientation of the yellow square directly on the star map after the first photo?
Because that would be great!
Best Regards
Chris
