By standard firmware, I assume you mean using the byte codes ala NQC or
something similar. If you only want semi-precise timing, you can use the
wait opcode to delay for approximately 100 ms between sensor samples. If
you want something more accurate, you can make use of a 1 ms timer to get a
better measurement of the actual delay incurred, or you can combine the
wait opcode with busy waiting on a timer to make the delay exactly 100 ms.
