Hardware Development / Re: AstroEQ Basic Hand Controllers
« on: August 09, 2020, 09:13:07 »
Is it possible to use the hand controller simultaneously with EQMod computer connection?
I have read somewhere in the posts that you have to use just one of the two types.

Can you share the covers for the nema17 motors?

This is my version of the hand controller with the 3 position switch. It works.

Hello Tom,
I am going to make the basic hand controller.
I have at home many parts but lack a 3.9KOhm resistor. But I can make it 3.93KOhm. How crucial :-) will it be for the system to use a slightly stronger resistor, or I have to buy 3.9KOhm one.

DIY AstroEQ / Plastic covers for the motors?
« on: September 13, 2019, 22:47:00 »
Hello everybody,
How have you solved the problem with not covered motors.
After upgrading with custom pulleys the RA and Dec motors and belts become open to air, humidity and dust.
Do you have any solution for this?

DIY AstroEQ / Re: Bootloader issue when burning it via Arduino Mega2560
« on: May 01, 2018, 17:50:42 »
Hello again,
Unfortunately the Bitbucket project for programming the AstroEQ PIC controller hasn't worked for me.
That project is originally made to support pics of the series: PIC18F2420 and then extended to:
18F2420
18F2455
18F2520
18F2550
18F4420
18F4455
18F4520
18F4550
but only the 18F2550 and 18F4550 have been tested, it is written in the readme, and AstroEQ's pic is PIC18F14K50.
Has anybody tried it anyway?

Hello Tom,
Thank you for the answer.
I will try it ASAP.

DIY AstroEQ / Re: Bootloader issue when burning it via Arduino Mega2560
« on: April 30, 2018, 22:43:04 »
Hello again,
Before uploading the firmware, do I have to program the PIC microcontroller with this hex file: AstroEQ USB-Serial.hex which is found under folder tree: AstroEQ-Firmware\Driver (Atmega162 Version) ?
I have found a way of flushing the PIC microcontroller with an arduino simulating the PICkit - it is the project by Kirill Kulakov in bitbucket called Arduino as a Pic18F programmer.
https://bitbucket.org/JoseFuzzNo/arduino-as-pic18f-programmer-for-linux.git
I guess after that I will be able to attach the AstroEQ controller via usb to PC and it will be recognised and I will be able to configure it with the config utility.
Is the above correct?
Regards
Grozdan

Hello Tom,
The small one I haven't programmed it the PIC micro controller.
I was thinking that after putting the boot loader in the chip then the device should appear and be recognised when plugged in with USB?
Did I miss anything else related with the boot loader?
May be I missed the steps and description for it in GitHub etc. and where should I read about it?

DIY AstroEQ / Re: hex upload error to NEW atmega162 IC
« on: April 30, 2018, 16:07:58 »
Hello can you describe how you burned the boot loader on the chip?
Have you used Arduino and what programmer.
I have issues with the boot loader putting it on the chip.
The Arduino IDE completes with success , but when connecting the AstroEQ via USB to the computer it is not detected and nothing happens.

DIY AstroEQ / Bootloader issue when burning it via Arduino Mega2560
« on: April 29, 2018, 23:04:32 »
Hello Tom,
This is a great project! And as an amateur astronomer I am trying to make it work for me.
I am trying to build my own AstroEQ from the shared project on gitlab.
I have the PCB and all the components soldered on it.
Now I have an issue when burning the bootloader from gitlib project.
1. I am using Arduino IDE v1.8.5
2. as a programmer I am using Arduino Mega2560.
On the mega the ICSP pins are 50,51,52,53 (instead of 10,11,12,13 on the UNO), Vcc, Gnd
In order to program the AstroEq with the bootloader I programmed the Arduino Mega with the example project ArduinoISP that is to make the arduino a programmer. The example is given for Arduino UNO, so I replaced the digital pin definitions in the code to correspond to 50-53.
From an old arduino forum thread I have read your discussion from year 2012, so I made the adjustments on the Arduino
This is the thread:
https://forum.arduino.cc/index.php?topic=104693.0
Here in the boards.txt I have added your properties + one more: atmega162.bootloader.tool=avrdude
and corrected the high fuses to be: 0xDC nstead of 0xD8
So the extra part in boards.txt looks like:
##############################################################
atmega162.name= ATmega162
atmega162.upload.protocol=arduino
atmega162.upload.maximum_size=14336
atmega162.upload.speed=57600
atmega162.bootloader.tool=avrdude
atmega162.bootloader.low_fuses=0xFF
atmega162.bootloader.high_fuses=0xDC
# atmega162.bootloader.high_fuses=0xD8
atmega162.bootloader.extended_fuses=0xFB
atmega162.bootloader.path=optiboot
atmega162.bootloader.file=optiboot_atmega162.hex
atmega162.bootloader.unlock_bits=0x3F
atmega162.bootloader.lock_bits=0x0F
atmega162.build.mcu=atmega162
atmega162.build.f_cpu=16000000L
atmega162.build.core=arduino
atmega162.build.variant=atmega162
##############################################################
I have added the pins_arduino.h to the folder you described and also replaced the iom162.h file.
As a result I have in Arduino IDE ATmega162 as an option,
I try to burn the bootloader , arduino IDE actually burns it successfully , it takes a few seconds to do it, the arduino leds blink and the AstroEQ status led blinks several times while burning process. Status in IDE is success.
When I try to connect the AstroEQ to the computer via USB - there is nobody there. Windows does not detect the controller and no led blinks at all. Nothing in device manager.
Any help will be appreciated.
Thank you.
