Note:

Filter 0 implies no digital IIR filter, but there is a 125 Hz ± 35 Hz single pole response

from the MEMS sensor

4. Application Information

Command	Function Description/Response
R	Reset. Resets the LE-60-F firmware to default settings. An ASCII ‘H’ (72) is sent in response.
G	Get Angle Data Packet. The LE-60-F returns its current angular position. The data is in a 6 byte packet defined in Table 2
N<0-9>	Set Resolution Level. A 2 byte command sequence that configures the LE-60-F internal digital filter. The second byte, an integer of value 0-9, sets the level of filtering.
C	Continuous Mode: Transfers packet continuously at maximum rate.
S	Stop Continuous Mode

Byte	Description	Note: Angles are represented as two’s complement 16 bit numbers. +90° corresponds to 32,767. -90°corresponds to -32,768. The 16-bit signed angle can be obtained by this simple ‘C’ expression: (int) Roll LSB + (int) 256 * Roll MSB
0	Header (always 255)
1	Pitch MSB (0-255)
2	Pitch LSB (0-255)
3	Roll MSB (0-255)
4	Roll LSB (0-255)
5	Checksum (8-bit sum　of bytes 1-4)
