Hi all, i just wanted to read the temperature of an LM75(I2C).
My firmware is a build with the version "30" sdk. So i use the newest SDK. I used the code from here (little bit modified for the LM75), http://foxlx.acmesystems.it/?id=10 and the header files from this article. http://foxlx.acmesystems.it/foxlx_acmesystems_it/00010/etraxi2c.h http://foxlx.acmesystems.it/foxlx_acmesystems_it/00010/i2c_errno.h anytime i start it, i get the message: Open error on /dev/i2c Do i need to do some config on the I2C to use it? And the next question, Geert Vancompernolle wrote in his PDF that i can use (void i2c_read( unsigned char slave, unsigned char* rbuf, unsigned char rlen );) and so on.. But where i can find this prototypes? Is the article about I2C on ACME to old? Hope anyone can help me Many thanks! rouven
