}
and for a 2 days im completely stuck with reading data from LIS3DH, i guess my functions for writing and reading are fine. my read buff is just uint8_t read_buff[1] im setting ctrlreg1 to enable normal mode with 400hz frequency(if i remember correctly) and trying to read some data. But ive discovered sth: 
why is it doing write operation then reading from 0x19 with 0x77 data, shouldnt it just write to 0x20 0x77 data?? and im only getting data that is 64 192 and 128. Nothing more.
