On the Panasonic EDMGRB8KJF there is a touchscreen. I connected it to = the AD0-3 on the gumstix but how do i enable it on the Kernel? I went to the Device Drivers->Touchscreens and there are 5 types. Which = one do i choose?UCB1400,Gunze,ELO Serial Touchscreen,Microtouch,ICS=20 Which one? Demetris Z . |

OK, i went untill the stage where i should patch the Kernel for TSLIB. i downloaded it, extracted to "package" added it to the config.in file enabled it in menuconfig MAKE now when it asked what file to patch i wrote=20 gumstix-buildroot/build_arm_nofpu/tslib/configure.ac then i had this error: checking for arm-linux-g++... = /gumstix/gumstix-buildroot/build_arm_nofpu/staging_dir/bin/arm-linux-ucli= bc-g++ checking for C++ compiler default output file name... configure: error: = C++ compiler cannot create executables (it seems i don't have arm-linux-g++) How do i fix this?

Demetris, Do a make menuconfig in the buildroot directory. You should find an option to "build/install C++ support". Enable it and rebuild your buildroot. Couldn't be easier. -chris |

Nope, still the same error. I checked the staging_dir/bin i don't have "arm-linux-g++" in there how do i fix this?

Hello all, I am planning to use this ELM327 PIC chip to interface with the onboard diagnostics of my car: http://www.elmelectronics.com/DSheets/ELM327QS.pdf It outputs serial data; so I suppose I can connect it to one of the serial ports of Gumstix. The question is what voltage level does gumstix expect? Is it 3.3V? Looks like ELM327 may be talking 5V. This is all I got out of their datasheet - "pin17 - This is the RS232 data transmit output. The signal level is compatible with most interface ICs (output is normally high), and there is sufficient current drive to allow interfacing using only a PNP transistor, if desired." - Sumit |

Please don't reply to unrelated posts when starting new threads. It breaks threading.

So threading is not based on the subject line, eh? Sorry about that. Didn't know. Craig Hughes wrote: >Please don't reply to unrelated posts when starting new threads.

Threading is generally based on the "In-Reply-To" and "References" headers, since the subject line often changes with "Re", "Fwd" and whatnot inserted in there.

It seems to do that as a ""smart"" feature tough and as a last resort, since the headers have preference. Personally I don't like this feature but I don't know how to turn it off, supposing if it's possible. These things (and people creating unrelated sub-threads by replying and changing subject) leads to somewhat confusing threading... - Alexandre |

Hi Sumit, > It outputs serial data; so I suppose I can connect it to one of the > serial ports of Gumstix. The question is what voltage level does > gumstix expect? Is it 3.3V? Looks like ELM327 may be talking 5V. This > is all I got out of their datasheet - Looking a bit further, we see that the input threashold is between 1.0 and 1.3 volts. The TxD from the gumstix will be at 3.3v, so you should be able to connect the TxD directly to the RxD on the ELM327. The TxD from the ELM327 will be typically around 4.6v (also from the ELM327 datasheet). The gumstix doesn't like voltage above 3.3v so the simplest thing to do is to use a resistor divider. I'd pick something from one of the following pairings: 3.3k/6.8k 4.7k/10k 10k/20k (it's the ratio of the values that's important, they need to be approx 1:2). Connect the two resistors together, and connect the joining point to the gumstix RxD. Connect the other end of the lower valued resistor to the TxD on the ELM327 and the other end of the larger resistor to ground. -- Dave Hylands Vancouver, BC, Canada http://www.DaveHylands.com/ |

Ah, the voltage divider circuit (it's all coming back to me now)... Vout = Vin * (R2 / (R1+R2)) Thanks for your help, Dave. - Sumit Dave Hylands wrote: > Hi Sumit, > > >> It outputs serial data; so I suppose I can connect it to one of the >> serial ports of Gumstix.

Did anyone manage to get the touchscreen to work on gumstix with = Microwindows?(Nano-x) I got microwindows to work but i understand that it's not the same setup = as on tinyX . Demetris Z . |

The Panasonic touch screen i am using is four wire resistive touch = screen. Would this connect to Audiostix2 touchscreen pins? or is there = another setup for that? Demetris Z . |
