HEQ5 Microcontroller needed...

[FunkyKoval35]

Hi all

I have not working HEQ5 PRO mount. After checking everything, I found that one of the PIC16F886-I/SO(1148VVK - see picture) chip is burned - confirmed at electronic shop. Do anyone know where I can get a new one? I checked ebay and amazon, and other websites with no luck. By the way... Where can I found information what exactly chip do I need(clock speed, memory, etc...)?

And... if chip will be replaced, will I have to do something? Program it?

Adam.

as you say it may not be that simple
I used to buy standard chips and use an EPROM programmer to set the same chips to do different things depending on the device it was going into or what I wanted it to do

I'm not an expert, but I'm fairly sure a replacement will need programming ...

Look for a new board would be the way to go.....

Hi Adam,

Replacement chips can be obtained from:

http://uk.farnell.com/microchip/pic16f886-i-so/mcu-8bit-pic16-20mhz-soic-28/dp/1439538

The problem you will have is programming it... Skywatcher won't give you the software, and I very much doubt that the standard motor board updates will work, since the chip has to have an exsisting version installed.

Hope this helps.

Best regards.

Sandy.

Thanks for reply all

Yes, I think it will be too difficult to fix it by replacing chip - at least for me So, it looks I need to spend money for new motherboard - well, Rowan Belt Modification Kit needs to wait...

Hi

Do you know what caused the damage? You don't want to replace the board and have it happen again!

[FunkyKoval35]

Yes, I know... I accidentally plug in wrong cable(from guiding camera) to wrong socked(multi -purpuse) on hand-controller :/ Mount stopped working during calibration process on PHD2. Costly lesson...

Wow that's a serious design flaw, there should either be protection built into the circuit or the plugs should be different sizes.

I know my guide cable won't actually fit the handset port as it is RJ9 vs RJ11.

Well.. First of all I should be more careful with cables.

True, kinda easy mistake to make while fumbling around in the dark though :S
