24. t of MKI adapters supported by the firmware printed in ASCII format Listdev The listdev command returns the list of devices supported by the firmware printed in ASCII format Echo on The echoon command is used to activate the write command verbose mode Once this command is launched after every write command the firmware automatically performs also a read of the register just written This function is useful to check if the write has succeeded For instance if the echoon command is launched after a w2027 it results R2027 Echo off The echooff command stops the write command verbose mode Accelerometer FIFO Stream mode enable The fifostr command is used to enable the accelerometer FIFO Stream mode For more details see the AN3308 application note Accelerometer FIFO mode enable The fifomde command is used to enable the accelerometer FIFO mode For more details see the AN3308 application note Accelerometer Stream to FIFO mode enable The fifotrg command enables the accelerometer Stream to FIFO mode For more details see the AN3308 application note Accelerometer FIFO Reset enable The fiforst command enables the accelerometer FIFO Reset mode For more details see the AN3308 application note Gyroscope FIFO Stream mode enable The fifostr command is used to enable the gyroscope FIFO Stream mode Gyroscope FIFO mode enable The gfifomde command is used to enable the gyroscope FIFO mode Doc ID 023
25. turns 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 of the demonstration 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 OxC7 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 of the demonstration 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 of the demonstration 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 OxC7 to the register at address 0x20 for example the user i
