Must-haves for EASY DIY controller?

well hit a road block
*avrdude:stk500_sync():not in sync:resp=0x00
*avrdude:stk500_disable(): protocol error, expect=0x14, resp=0x51
checked comm port its right, checked board setting its right
I've tried figuring out why it wont sync?? tried pulling plug on usb and resetting nothing as of yet.
 
Are you using the usb-bub? This error usually means that your chip is not resetting at the right time for programming.
 
Just out of curiosity, have you tried turning it 180 degrees and plugging it in? Are the LED's blinking/flashing at all?
 
No I haven't tried to turn it 180, I checked to ensure that the silk screen on the board pins matched the ones on the hydra and they do, does it matter which it is connected to the master or the slave? I have tried both with the same results, I will try a different computer when I get home tonight.
Yes the leds on the breakout board flash when both plugged in and when I attempt to upload. Do you think I need also the external power supply and not just the usb as power?
 
It matters if it is the master or slave in terms of which one you're programming, doesn't matter for your error.

The USB power should be enough unless you have some short on the board and the computer is shutting down the USB. In this case you don't need external power, but to fix the short.

Check your windows logs to see what happens when the USB is plugged in. I don't have windows so can't really tell you where they go (any windows gurus here? ).

I would go to http://www.ftdichip.com/Drivers/VCP.htm and install the latest driver and try again.

Terhz - have you gotten around the bug in arduino-0022 that prevents your code from compiling? I had to use an older version, arduino-0021, in order to get your code to compile.

I should be fixed now, if the workaround they provide in the bug report works. Give it a try and let me know. Note the new Hydra.h file.
 
Wiki

Wiki

Since it is hard to keep track of all the available information on building/firmware etc. in this thread, we've put together a little wiki for the project that we'll be updating as we go. It contains a little build guide and most of the information spread out here.

http://hydra-reef.com/wiki/Home

This still remains the main place for discussion and questions. We are not in any way moving away from Reef Central.

Also, the project is still very much in progress. The firmware is still missing functionality so if you plan to build a controller at this point, consider yourself a beta tester (if not alpha) :).
 
well I've checked the event log and It does not show any issues FYI for people to check on windows go to start---run----type eventvwr will open the log for you.
I am currently sitting with mag glass looking for shorts.
 
You can try shorting TX and RX on the FTDI board, connect to it with hyperterminal and type something. If the driver and board are working, you should see whatever you type come back.
 
Help --- I've said this before, but need a solution. I made a CA42 cable hack to use with Hydra. It works fine as a serial connection, in other words, I can see all the Serial.print() commands just fine.

BUT -- It won't let me download code.

So ... Which BUB is being used to successfully download code to the Hydra. Specific vendor, model, etc.

Looks like I need to spend a few dollars more.

I am using the one from Modern Device http://shop.moderndevice.com/products/usb-bub
 
Well since mine was from a different source and I am having problems, I went ahead and ordered this usb-bub this way thats one more thing I can rule out.
 
kctango and bd98072, did you guys try what I suggested? Bridge TX and RX, connect to the port with a terminal emulator and type any text. That will at least tell you if you've done the driver/serial board part right.

bd98072, sounds like your RX is working (if you can read serial printouts from the arduino board) but your TX isn't (you can't upload). Some of the CA42 cables might have different colors/pins so you might have the wrong TX pin.
 
Terahz,
windows 7 has done away with hyperterminal so I have not done that test as of yet, I am looking for another program that works with windows 7 that will do it. Otherwise I am awaiting my son to come home over the weekend with his laptop which still has XP on it with hyperterminal. But I figured for 14.00 I might as well order the other bub just in case this way its on its way. If it turns out that my bub I currently have is ok then I can always pass it on to someone that can use it in their build.
 
Board found and shipping tomorrow. Thanks kctango.

I now need the ELN board for the Meanwells please PM me if you have this or how can I make one?
