Hello all! I am newbie here, i got my tiny4412 last week and have installed linux in it. I'm making some project ADC with the i2c protocol which will gather the data and show it. I wonder if the data can be showed in some apps in my qtopia, i have read a little about qt, but still i am confusing. Do you have any idea or good reading for my little steps to build the project? thank you.
Have a look through these sites: http://paolosereno.info/ He had more info on an older site. Also, search <domdom> on this site, which hopefully will take you to collection of his tutorials. Then read through this stuff: http://mini2440vietnam.blogspot.co.nz/
hey davef nice to meet u. thank you i will read it first, then i'll come back after it.
Hi all, thanks Dave to redirect to my new blog. I'm changing the web provider and I had some trouble to move the domain, so I decided to redirect all the requests to the address you wrote in your post. At the moment I put online the most requested tutorials, but there is much more material I have to move to the new site. Please stay tuned. Regards, Paolo
hi paolo soreno Thank you, i am waiting for your new site. but i have tried some of the qt stuff in your site really helpful. regards azihsan
@azihsan Thanks for your feedback. It's important for me to know that the Qt stuff in my site is helpful to someone. Regards Paolo
hi all is anyone has an example of i2c code, i'm confusing to start writing the code?
Hey all i have finished to build a cross compiled program for i2c, but when i am tryin to run in my tiny4412 it came PERMISSION DENIED, so what shuold i do?
Hey I just solved the problem with chmod +x myExeName but i got a problem again with my i2c bus channel, when i tried i2c-0 and i2c-1, the result came up with -1 what should i do?
On your host computer command line type: readelf -a <your_cross_compiled_program> and copy the last 10 lines or so from the output
is it like this davef? File Attributes Tag_CPU_name: "ARM1176JZF-S" Tag_CPU_arch: v6K Tag_ARM_ISA_use: Yes Tag_THUMB_ISA_use: Thumb-1 Tag_FP_arch: VFPv2 Tag_ABI_PCS_wchar_t: 4 Tag_ABI_FP_denormal: Needed Tag_ABI_FP_exceptions: Needed Tag_ABI_FP_number_model: IEEE 754 Tag_ABI_align_needed: 8-byte Tag_ABI_align_preserved: 8-byte, except leaf SP Tag_ABI_enum_size: int Tag_ABI_HardFP_use: SP and DP
hey davef it seems i succeed to open the i2c file.
but i cant read my ADC ic, i use this code, is there something wrong?
because i completely succeed to run the program in my Pi.
int numberBytes = ADS1110_Buffer;
int bytesRead = read(file, this->dataBuffer, numberBytes);
if (bytesRead == -1){
cout << "Failure to read Byte Stream in readFull()" << endl;
}
Tag_CPU_name: "ARM1176JZF-S" Tag_CPU_arch: v6K These indicate that at least your have cross-compiled it for ARM. I am not familiar with the exact name and arch, so you have to look those up.
Sorry, unless I actually tried it myself I can not be of anymore help. I think for anyone to help they would need to see the whole program.
Yes davef thanks a lot anyway. i will continue it again.
