DIY AstroEQ / Re: Dec Slow goto rate
« on: January 23, 2020, 08:37:03 »
Which version of the configuration utility are you using? I've just released a new version (3.9.2) which should fix some issues with uploading of DEC speed and gear changing parameters.

General Discussion / Configuration Utility Corrections
« on: January 21, 2020, 09:48:26 »
Hi all,

A flaw has been found in the configuration utility which was resulting in some of the configuration settings (e.g. DEC goto speed) not being uploaded to the AstroEQ.
This has been around since about v3.8.0 of the utility.

I've released a new version (available from the downloads page). I would recommend upgrading to the new version and uploading the configuration to your device again.

Apologies for the mistake.

Kind Regards,

1. Correct, the schematic shows R21's location between D21 (SCL) and D23
2/3. ST-4 pins connect to ground to trigger motion in the corresponding direction.
4. Yes.
5. The motors wiring is as per the schematic.
6. See https://www.astroeq.co.uk/tutorials.php?link=faqs#making_connections for cable connectivity.

Hi Pierre,

Correct, you don't need the Arduino IDE. The command will basically do the same thing that the IDE does under the hood.

The fuses are embedded within the command (the -Uefuse, -Uhfuse, -Ulfuse parts).

Dear Pierre,

Please read the instructions carefully. I haven't mentioned anything called "optiboot.exe".

Download the config utility (assuming you haven't already)

Lets say you extracted the config utility to
Code: [Select]
Save the following file (https://github.com/TCWORLD/AstroEQ/raw/master/AstroEQ-Bootloader/optiboot_atmega162.hex) to:
Code: [Select]
Open windows command prompt (cmd.exe) and change directory:
Code: [Select]
cd C:\Temp\AstroEQ
As you are using ArduinoISP, enter the following command exactly as shown, changing COM10 to whatever COM port your Arduino Uno is presenting as:
Code: [Select]
bin\avrdude -Cetc/avrdude.conf -v -v -v -patmega162 -cstk500v1 -P\\.\COM10 -b19200 -Uefuse:w:0xFB:m -Uhfuse:w:0xDC:m -Ulfuse:w:0xFF:m -Uflash:w:hex/optiboot_atmega162.hex:i -Ulock:w:0x0F:m
This should burn the bootloader - if successful you will see lines like "xxx bytes verified successfully".

The easiest way is to use the AVRdude files that come with the config utility.

  • Save the optiboot_atmega162.hex file into the hex/ folder of the config utility
  • Open command prompt and change directory to the config utility folder (where AstroEQ.exe is located)
  • Run one of the following two commands depending on which avr programmer you are using:
ArduinoISP (chance -P\\.\COM10 to whichever COM port number your Arduino shows up as):
Code: [Select]
bin\avrdude -Cetc/avrdude.conf -v -v -v -patmega162 -cstk500v1 -P\\.\COM10 -b19200 -Uefuse:w:0xFB:m -Uhfuse:w:0xDC:m -Ulfuse:w:0xFF:m -Uflash:w:hex/optiboot_atmega162.hex:i -Ulock:w:0x0F:m
AVRISP MKII (or equiv):
Code: [Select]
bin\avrdude -Cetc/avrdude.conf -v -v -v -patmega162 -cavrispmkii -Pusb -Uefuse:w:0xFB:m -Uhfuse:w:0xDC:m -Ulfuse:w:0xFF:m -Uflash:w:hex/optiboot_atmega162.hex:i -Ulock:w:0x0F:m

Have you clicked the Upload Firmware button in the config utility - you will need to do this first before trying to configure.

Hi Pierre,

The firmware is precompiled, so all you need to do is download the config utility (https://www.astroeq.co.uk/downloads.php), run the AstroEQ.exe file, and select the Arduino Mega option from the drop down. Full instructions for the config utility are here (https://www.astroeq.co.uk/tutorials.php?link=config).

Kind Regards,

AstroEQ Support / Re: Having trouble opening EQMOD
« on: January 07, 2020, 20:32:07 »
The config utility failing to open EQMOD is not suggesting of an issue with the hardware, but something to do with ASCOM - possibly installed in an unexpected location, or some component missing.

Would you be able to try loading EQMOD using either a star chart software such as Cartes du Ceil, or using the "eqascom_run.exe" file in the EQMOD installation directory to see if that loads it up?

Kind Regards,

Hmm, not sure.

If you connect pins 10 and 12 of the PIC together and connect via a serial termial (e.g. PuTTY or similar), do you get data echoing back? That would rule out the PIC/USB as an issue, leaving just the ATMega.

Apologies for the delay.

That soldering looks pretty good.
I would check the ground of C15 which looks like it hasn't taken. The same goes for one side of R15 which may be an issue.

Might also be worth checking pin 15 of the RA motor driver - the ground looks like a bad joint, though that wouldn't affect programming.

If that doesn't help, the next check is to make sure all pins of the ATMega and PIC are correctly in the socket (sometimes they can fold over or miss). You could also try removing and reinserting just to be sure.

Let me know how it goes.

Kind Regards,

Excellent. Glad it's sorted.

Could you check C13 and C14 first, there appears to be a solder short between them which would stop the crystal oscillating.

« on: December 11, 2019, 21:08:14 »
Can't see anythign visibly wrong with the board, other than one end of R14 isn't soldered, but that wouldn't cause an issue as it is just the power LED.

I'll post out another ATMega to you tomorrow. It will be interesting to know if it is a faulty chip.

Kind Regards,
