Hi,

 

Output data rate 3200HZ.. means that we could see the 3200 samples per second on serial terminal?

For my university project I'm working on ADXL345 with nucleo-L053 (ST controller). I always see same data rate about 350HZ on serial terminal at 115200 baud rate.

For 50HZ input (BW_Rate register = 0x09) the output at serial terminal is 50 variations but with 350 samples per second. Means one samples displayed for about 7 times.

For 100HZ input (BW_rate register = 0x0A),the output at serial terminal is with 100 variatons but with 350 samples per second. each sample almost dislyed 4 times. Is this normal? or?

I need high data rates for my project like 3200HZ and 1600HZ.. Can i able to see 3200 samples per second on serial terminal.

My serial terminal is showing maximum 650 samples per second at high baud rate like 921600.

Thank you.
