Re: I2C not reliable

Hi! Thanks for the hint to the SMBUS protocoll, I got rid of Wiringpi and I got it working! Now I can read the double ( which is actually 8 byte :) ) over I2C Here is a part of my program: #include <linux/i2c-dev.h> //include this file for native I2C void mainBoard::readMCU() { int opResult = 0; // ...

Re: Can't get I2C to work correctly

Do you have an Oscilloscope? Try to hook it up to (at least) the SCK Line. I had this problem before. After doing several i2cget and i2cset the lines were always low and I had to powercycle (not only reboot) the Pi.

Re: I2C not reliable

I got it working! It looks like the default speed of the I2C Port is to slow (?). I set it to 1Mhz, now it is working flawlessly :) EDIT: Maybe I can use this thread for another question. How do I read a 32bit Value using WiringPi? My Arduino is sending it in 4 bytes. I tried to read it like this: i...

Re: Connect to HTTP server from internet

If you can reach it from within the network, there is an error in your router setting I think. Did you really forward Port 80 from outside to Port 80 of the raspberry pi? Maybe try to forward the external port 1234 to the raspberry port 80. Then you just have to try "yourexternalIP:1234" to reach it...

Re: Rotate 7" Touch Display 90°

Ah, Okay. I thought it was also meant to turn the display in a 90° angle. Is it possible to implement it? where is this handled? The rotation of the touch mask in 180° step works, so it would just be needed to set it to 90 instead of 180 degree steps :)

Re: Rotate 7" Touch Display 90°

Well, LCD_rotate just flips the display 180°, so it doesnt do what it is supposed to do,in windows and Linux (display_rotate works)... display_rotate rotates the display, as it should. lcd_rotate just flips the display and the touchmask in 180° steps. I think there is something wrong in the handover...
