Supported commands
UM0979
Accelerometer register read
The *rAA command allows the contents of the accelerometer registers in the demonstration
kit board to be read. AA, expressed as a hexadecimal value and written in upper case,
represents the address of the register to be read.
Once the read command is issued, the board returns RAAhDDh, where AA is the address
sent by the user and DD is the data present in the register.
For example, to read the register at address 0x20, the user issues the command *r20, which
returns, e.g., R20hC7h.
Accelerometer register write
The *wAADD command allows writing to the contents of the accelerometer registers in the
demonstration kit board. AA and DD, expressed as hexadecimal values and written in upper
case, represent, respectively, the address of the register and the data to be written. For
example, to write 0xC7 to the register at address 0x20, the user issues the command
*w20C7.
Gyroscope register read
The *grAA command allows the contents of the gyroscope registers in the demonstration kit
board to be read. AA, expressed as hexadecimal value and written in upper case,
represents the address of the register to be read.
Once the read command is issued, the board returns GRAAhDDh, where AA is the address
sent by the user and DD is the data present in the register.
For example, to read the register at address 0x20, the user issues the command *gr20,
which returns, e.g., GR20hC7h.
Gyroscope register write
The *gwAADD command allows writing to the contents of the gyroscope registers in the
demonstration kit board. AA and DD, expressed as hexadecimal values and written in upper
case, represent, respectively, the address of the register and the data to be written. To write
0xC7 to the register at address 0x20, for example, the user issues the command *gw20C7.
Magnetometer register read
The *mrAA command allows the contents of the magnetometer registers in the
demonstration kit board to be read. AA, expressed as a hexadecimal value and written in
upper case, represents the address of the register to be read.
Once the read command is issued, the board returns MRAAhDDh, where AA is the address
sent by the user and DD is the data present in the register.
For example, to read the register at address 0x00, the user issues the command *mr00,
which returns, e.g., MR00h10h.
Magnetometer register write
The *mwAADD command allows writing to the contents of the magnetometer registers in
the demonstration kit board. AA and DD, expressed as hexadecimal values and written in
upper case, represent, respectively, the address of the register and the data to be written. To
write 0x20 to the register at address 0x01, for example, the user issues the command
*mw0120.
