hi everyone, i trying to read data from the accelerometer of this sensor conneted to an an xbee XB24CZ7PISB003 programmable . i found this function http://exsilium.github.io/xbee-sdk-doc/ ... __i2c.html but i don't am sure about if i can use one sensor with i2c protocol on my xbee.. this, because in the datasheet i have no found anything about i2c protocol but only about uart and spi.. i try to write on codewarrior the sample api i found, in this way : i2c_config(0); i2c_set_addr(0x68); rtc_set_timeout(HZ *2); for (; { now = rtc_get_uptime(); if (rtc_timeout_expired() ) { n=i2c_read(txbuf, 16); printf("bytes read %d -",n); printf("reading : %s\n\n", txbuf); rtc_set_timeout(HZ *5); } i have connect the sda to pin 8 , the scl to pin 32, like codewarrior says. and grn and vcc to 3.3V where i am wrong? is it 0x68 correct? and some resistors? thanks a lot!
