I am not keeping up with this, I am not documenting what works and what doesn't, and I just ignore all the readers.
Sorry
I'll be very humble in this post. Lots has changed. I bought a new desktop computer. This thing seems really good. It has two USB ports in the front of it, so I think that will help with things. Certainly the arduino plugs in nicely. I have the tablet, and a new phone. They are both Samsung Android devices. This is good, they both share nicely, so I can probably have some success.
Looking back, and trying to get things where I was, well, I am not having any luck. I reinstalled the Arduino IDE, and looking back at my notes, I guess I missed some setups. The IDE won't let me talk to the board. The driver says successfully installed, but everytime I plug in, I get uh-ah sound from windows. This is Windows7, and I am following the instructions on the
Arduino install page.
It seems the Arduino page isn't up to snuff. I went right to the
FTDI page for the
instructions on how to install the Windows 7 x64 device drivers (I don't think the 64 bit Intel drivers are included with Arduino at this time). Yes, the instructions appear to make you do the same update driver twice, but yes you need to!
Even wanting to go back to where I was, I don't find any of my software, although it is probably on my old computer. How could you have duplicated, or improved my work? I need to do better than that. I am trying to be more open, and I hope you can understand.
This time the board is a Mega128, and the board is on Com3. I was able to test this by trying the "Burn Bootloader" option in the tools menu of the IDE and watching the Rx/Tx LEDs blink.
I may go back in grab all the files off that old computer, and then try again, or I may start from scratch?
There seems to be a new
Arduino to Android project on Hackaday again. It is using bluetooth, so I will give it a go.
I'll try to keep motivated, and put up code this time.
The Bluetooth device is called linvor 00:11:04:15:10:87, and the login is 1234. I believe the bluetooth shield is still on 9600 baud. I keep getting the error:
avrdude: stk500_getsync(): not in sync: resp=0x00
with the shields on. With the shields off, it works fine. Maybe I need to turn off the bluetooth shield while I am uploading code? There is a switch, one side labeled "to board" the other labeled "to ft232". I can upload the code, with the switch on the "to ft232" side, and get no errors. I can also get serial data from the board to my phone using the serial monitor, without changing the switch. I don't receive anything from the phone though.
This is the code that is included from the Arduino to Android project

To do more testing, I probably need to add some LED's or something.
That is all for tonight, it is getting late.
