+ * 42, 45, and 48). When more than zero bytes are read (I2C_SLVx_LEN > 0) from
+ * an enabled slave (I2C_SLVx_EN = 1), the slave is read at the Sample Rate (as
+ * defined in Register 25) or delayed rate (if specified in Register 52 and
+ * 103). During each Sample cycle, slave reads are performed in order of Slave
+ * number. If all slaves are enabled with more than zero bytes to be read, the
+ * order will be Slave 0, followed by Slave 1, Slave 2, and Slave 3.
+ *
+ * Each enabled slave will have EXT_SENS_DATA registers associated with it by
+ * number of bytes read (I2C_SLVx_LEN) in order of slave number, starting from
+ * EXT_SENS_DATA_00. Note that this means enabling or disabling a slave may
+ * change the higher numbered slaves' associated registers. Furthermore, if
+ * fewer total bytes are being read from the external sensors as a result of
+ * such a change, then the data remaining in the registers which no longer have
+ * an associated slave device (i.e. high numbered registers) will remain in
+ * these previously allocated registers unless reset.
+ *
+ * If the sum of the read lengths of all SLVx transactions exceed the number of
+ * available EXT_SENS_DATA registers, the excess bytes will be dropped. There
+ * are 24 EXT_SENS_DATA registers and hence the total read lengths between all
+ * the slaves cannot be greater than 24 or some bytes will be lost.
+ *
+ * Note: Slave 4's behavior is distinct from that of Slaves 0-3. For further
+ * information regarding the characteristics of Slave 4, please refer to
+ * Registers 49 to 53.
+ *
+ * EXAMPLE:

+// I2Cdev library collection - MPU6050 I2C device class, 6-axis MotionApps 6.12 implementation
+// Based on InvenSense MPU-6050 register map document rev. 2.0, 5/19/2011 (RM-MPU-6000A-00)
+// 5/20/2013 by Jeff Rowberg
+// Updates should (hopefully) always be available at https://github.com/jrowberg/i2cdevlib
+//
+// Changelog:
+// 2019/7/10 - I incorporated DMP Firmware Version 6.12 Latest as of today with many features and bug fixes.
+// - MPU6050 Registers have not changed just the DMP Image so that full backwards compatibility is present
+// - Run-time calibration routine is enabled which calibrates after no motion state is detected
+// - once no motion state is detected Calibration completes within 0.5 seconds
+// - The Drawback is that the firmware image is larger.
+// ... - ongoing debug release

+/* File Name: TFMPlus.cpp
+ * Version: 1.5.0
+ * Described: Arduino Library for the Benewake TFMini-Plus Lidar sensor
+ * The TFMini-Plus is a unique product, and the various
+ * TFMini Libraries are not compatible with the Plus.
+ * Developer: Bud Ryerson
+ * Inception: v0.2.0 - 31 JAN 2019
+ * v1.0.0 - 25FEB19 - Initial release
+ * v1.0.1 - 09MAR19 - 'build()' function always returned TRUE.
+ Corrected to return FALSE if serial data is not available.
+ And other minor corrections to textual descriptions.
+ * v1.1.0 - 13MAR19 - To simplify, all interface functions now
+ return boolean. Status code is still set and can be read.
+ 'testSum()' is deleted and 'makeSum()' is used instead.
+ Example code is updated.
+ * v1.1.1 - 14MAR19 - Two commands: RESTORE_FACTORY_SETTINGS
+ and SAVE_SETTINGS were not defined correctly.
+ * v1.2.1 - 02APR19 - Rewrote 'getData()' function to make it faster
+ and more robust when serial read skips a byte or fails entirely.
+ * v1.3.1 - 08APR19 - Redefined commands to include response length
+ ********************** IMPORTANT ************************
+ **** Changed name of 'buildCommand()' to 'sendCommand()'. ****
+ ****************************************************************
+ * v.1.3.2 - Added a line to getData() to flush the serial buffer
+ of all but last frame of data before reading. This does not
+ effect usage, but will ensure that the latest data is read.
+ * v.1.3.3 - 20MAY19 - Changed 'sendCommand()' to add a second byte,
+ to the HEADER recognition routine, the reply length byte.
+ This makes recognition of the command reply more robust.
+ Zeroed out 'data frame' snd 'command reply' buffer arrays
+ completely before reading from device. Added but did not
+ implement some I2C command codes.
+ * v.1.3.4 - 07JUN19 - Added 'TFMP_' to all error status defines.
+ The ubiquitous 'Arduino.h' also contains a 'SERIAL' define.
+ * v.1.3.5 - 25OCT19 - Added missing underscore to parameter
+ in header file TFMPlus.h:
+ Line 138 #define BAUD_14400 0x003840
+ * v.1.3.6 - 27APR20 - a little cleanup in 'getData()'
+ * v.1.4.0 - 15JUN20 - Changed all data variables from unsigned
+ to signed integers. Defined abnormal data codes
+ as per TFMini-S Producut Manual
+ - - - - - - - - - - - - - - -
+ Dist | Strength | Comment
+ -1 Other value Strength ≤ 100
+ -2 -1 Signal strength saturation
+ -4 Other value Ambient light saturation
+ - - - - - - - - - - - - - - -
+ * v.1.4.1 - 22JUL20 - Fixed bug in sendCommand() checksum calculation
+ - Changed two printf()s to Serial.print()s
+ - Fixed printReply() to show data from 'reply' rather than 'frame'
+ * v.1.4.2 - 19MAY21 - Changed command paramter 'FRAME_5' to correct value.
+ It was set to 0x0003. Now it's set to 0x0005
+ * v.1.5.0 - 06SEP21 - Corrected (reversed) Enable/Disable commands in 'TFMPlus.h'
+ Changed three command names
+ OBTAIN_FIRMWARE_VERSION is now GET_FIRMWARE_VERSION
+ RESTORE_FACTORY_SETTINGS is now HARD_RESET

+ *
+ * Default settings for the TFMini-Plus are a 115200 serial baud rate
+ * and a 100Hz measurement frame rate. The device will begin returning
+ * measurement data immediately on power up.
+ *
+ * 'begin()' function passes a serial stream to library and
+ * returns TRUE/FALSE whether serial data is available.
+ * Function also sets a public one byte status code.
+ * Status codes are defined within the library.
+ *
+ * 'getData( dist, flux, temp)' passes back measurement data

+ * Error, if any, is saved as a one byte 'status' code.
+ *
+ * 'sendCommand( cmnd, param)' sends a 32bit command code (cmnd)
+ * and a 32bit parameter value (param). Returns TRUE/FALSE and
+ * sets a one byte status code.
+ * Commands are selected from the library's list of defined commands.
+ * Parameter values can be entered directly (115200, 250, etc) but
+ * for safety, they should be chosen from the Library's defined lists.

+/* File Name: TFMPlus.h
+ * Version: 1.5.0
+ * Described: Arduino Library for the Benewake TFMini-Plus Lidar sensor
+ * The TFMini-Plus is a unique product, and the various
+ * TFMini Libraries are not compatible with the Plus.
+ * Developer: Bud Ryerson
+ * Inception: v0.2.0 - 31 JAN 2019
+ * v1.0.0 - 25FEB19 - Initial release
+ * v1.0.1 - 09MAR19 - 'build()' function always returned TRUE.
+ Corrected to return FALSE if serial data is not available.
+ And other minor corrections to textual descriptions.
+ * v1.1.0 - 13MAR19 - To simplify, all interface functions now
+ return boolean. Status code is still set and can be read.
+ 'testSum()' is deleted and 'makeSum()' is used instead.
+ Example code is updated.
+ * v1.1.1 - 14MAR19 - Two commands: RESTORE_FACTORY_SETTINGS
+ and SAVE_SETTINGS were not defined correctly.
+ * v1.2.1 - 02APR19 - Rewrote 'getData()' function to make it faster
+ and more robust when serial read skips a byte or fails entirely.
+ * v1.3.1 - 08APR19 - Redefined commands to include response length
+ ********************** IMPORTANT ************************
+ **** Changed name of 'buildCommand()' to 'sendCommand()'. ****
+ ****************************************************************
+ * v.1.3.2 - Added a line to getData() to flush the serial buffer
+ of all but last frame of data before reading. This does not
+ effect usage, but will ensure that the latest data is read.
+ * v.1.3.3 - 20MAY19 - Changed 'sendCommand()' to add a second byte,
+ to the HEADER recognition routine, the reply length byte.
+ Zeroed out 'data frame' snd 'command reply' buffer arrays
+ completely before reading from device. Added but did not
+ implement some I2C command codes.
+ * v.1.3.4 - 07JUN19 - Added 'TFMP_' to all error status defines.
+ The ubiquitous 'Arduino.h' also contains a 'SERIAL' define.
+ * v.1.3.5 - 25OCT19 - Added missing underscore to paramter:
+ #define BAUD_14400 0x003840
+ * v.1.3.6 - 27APR20 - a little cleanup in 'getData()'
+ * v.1.4.0 - 15JUN20
+ 1. Changed all data variables from unsigned to signed integers.
+ 2. Defined abnormal data codes as per TFMini-S Producut Manual
+ - - - - - - - - - - - - - - - -
+ Distance | Strength | Comment
+ -1 Other value Strength ≤ 100
+ -2 -1 Signal strength saturation
+ -4 Other value Ambient light saturation
+ - - - - - - - - - - - - - - - -
+ * v.1.4.1 - 22JUL20 - Fixed bugs in TFMPlus.cpp
+ * v.1.5.0 - 06SEP21 - Corrected (reversed) Enable/Disable commands
+ Changed three command names
+ OBTAIN_FIRMWARE_VERSION is now GET_FIRMWARE_VERSION
+ RESTORE_FACTORY_SETTINGS is now HARD_RESET
+ SYSTEM_RESET is now SOFT_RESET
