Hi guys,
I open a thread because I've been trying since two days , searching the net , and I think I've exhausted all possibilities , there must be something that is going ignored me , but I can not see it.
I bought 2 Arduino pro mini and adapter , these are:
http://www.ebay.es/itm/121192432250?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649
http://www.ebay.es/itm/300935559844?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649
But I can not program it. The mini pro is not responding.
What I 've tried :
- I connected the adapter and win7 I recognized me , I connected as it should GND -> GND supposedly 5V- > VCC TX- > RX and RX- > TX but nothing.
- Same but investing TX and RX , nothing.
- Giving the reset for a second, nothing .
- Giving to reset until you get the message bytes , nothing.
- Giving to reset the adapter until a second I see the TX LED , illuminates nothing .
- Giving to reset until just before the TX LED lights , nothing.
- I saw that there were problems with win7 with drivers , so I installed an old version , nothing.
- Leo this thread , New Pro Mini atmega328 5V 16M (clone) - not in sync - solved - Other Hardware Development - Arduino Forum , same components I , 115200 baups change nothing .
- I try to pins of the side , instead of the end , as it could have bad soldier or something , nothing.
- I installed a virtual machine with windows XP , nothing.
- I try different cards in the program , 5v, 3v , all possibilities , nothing.
- I tried to use the adapter to program an arduino nano, and it worked perfectly . ( this means that the adapter / setup is correct ? )
Always the same error: avrdude stk500_getsync () not in sync resp = 0x00
Now comes the horny , I say , well , let's try using the arduino nano as an adapter to program the mini and the following occurs :
- I connect everything, 5v -> VCC GND -> GND TX- > RX RX- > TX right ... I hit the reset and nothing, same error.
- I connect the nano to RST PIn DTR mini and go , now it seems that if it works , do not give me any error, the LEDs blink , the nano is set to blink , the mini as you hear rain. Le LEd to connect a normal 13 pin mini , to see it better , but hey, it flashes every 16 seconds (same as having integrated) nothing to do with what I have allegedly sent .
- Change the flicker delays in the nano works, the mini remains the same, at your pace.
- Change the TX and RX and invest , and ... DO NOT GIVE ME ANY ERROR ! ? WTF? the mini course at their own pace , the nano program.
- Change the program to Nano card , same result.
- Change in a mini card program , same result.
So at this point I am, I think the adapter works well , since its LED TX if ignited , tries to send , and the nano has worked flawlessly I even doing manual reset as the first .
All indications are that the arduino mini pro is faulty but I do not. First because it turns perfectly and status LED flashes occasionally , and second because I bought two , and they both do exactly the same .
So I would like any suggestions or something you are overlooking. Now the last thing I would try is a tutorial to make an auto -reset the adapter, but this risk http://www.instructables.com/id/Arduino-USB/?ALLSTEPS blow the adapter because welding is very small, I would like to see if I'm doing something wrong before.
Thank you and sorry for my english.
Updated!
I made the auto-reset of http://www.instructables.com/id/Arduino-USB/?ALLSTEPS and it works perfectly, the led of arduino pro mini flash 3 times few milliseconds before attempting to send the code, but nothing changes.
Moreover I tried to install into ubuntu and nothing, everything exactly the same, so you can rule out a driver issue, or USB.
I've also changed the baud rate to 115200 in preferences.txt but nothing.
Now I am in a dead end, any ideas?
