ADIS16227 - Microcontroller No-OS Driver

Supported Devices

Evaluation Boards

Overview

The ADIS16227 iSensor® is a complete vibration sensing system that combines wide bandwidth, triaxial acceleration sensing with advanced time domain and frequency domain signal processing. Time domain signal processing includes a programmable decimation filter and selectable windowing function. Frequency domain processing includes a 512 point, real-valued FFT for each axis, along with FFT averaging, which reduces the noise floor variation for finer resolution. The 16-record FFT storage system offers users the ability to track changes over time and to capture FFTs with multiple decimation filter settings.

The goal of this project (Microcontroller No-OS) is to be able to provide reference projects for lower end processors, which can't run Linux, or aren't running a specific operating system, to help those customers using microcontrollers with ADI parts. Here you can find a generic driver which can be used as a base for any microcontroller platform and also specific drivers for Renesas platforms.

HW Platform(s):

Driver Description

The driver contains two parts:

  • The driver for the ADIS16227 part, which may be used, without modifications, with any microcontroller.
  • The Communication Driver, where the specific communication functions for the desired type of processor and communication protocol have to be implemented. This driver implements the communication with the device and hides the actual details of the communication protocol to the ADI driver.

The Communication Driver has a standard interface, so the ADIS16227 driver can be used exactly as it is provided. There are three functions which are called by the ADIS16227 driver:

  • SPI_Init() – initializes the communication peripheral.
  • SPI_Write() – writes data to the device.
  • SPI_Read() – reads data from the device.

Driver architecture

The implementation of these three functions depends on the used microcontroller.

The following functions are implemented in this version of ADIS16227 driver:

Function Description
unsigned short ADIS16227_GetRegister16Value(unsigned char registerAddress) Reads the value of a register.
void ADIS16227_SetRegister8Value(unsigned char registerAddress, unsigned char registerValue) Writes 1 byte into a register.
void ADIS16227_SetRegister16Value(unsigned char registerAddress, unsigned short registerValue) Writes 2 bytes into a register.
unsigned char ADIS16227_Init(void) Initializes the SPI and checks if the ADIS16227 part is present.
void ADIS16227_ConfigCapture(unsigned char window, unsigned char sampleRate, unsigned char pwrDwn, unsigned char range, unsigned char mode) Configures the ADIS16227_REC_CTRL register.
unsigned char ADIS16227_DataReady(void) Reads the value of the “Data ready/busy” bit (DIAG_STAT register).
void ADIS16227_Capture(void) Initiates a manual data capture and wait until the process is finished.
void ADIS16227_GetBuffers(unsigned short* x, unsigned short* y, unsigned short* z, unsigned short samplesNumber) Reads “samplesNumber” samples from each axis's buffer.
unsigned short ADIS16227_GetPowerSupplyInfo(void) Reads the power supply voltage and returns the data in mV.
char ADIS16227_GetTemperatureInfo(void) Reads the internal temperature and returns the data in degrees Celsius.

  ADIS16227/PCBZ J1 connector Pin 10 (VCC) → YRDKRL78G13 PMOD1 connector Pin 12

Software Setup

With the Applilet3 for RL78G13 tool the following peripherals have to be configured:

CSI10 (Clocked Serial Interface 10) – For the ADIS16227 part and the ST7579 LCD

Choose to generate the Transmit/receive function for the CSI10 and configure the interface with the following settings:

  • Transfer mode setting: Single transfer mode
  • Data length setting : 8 bits
  • Transfer direction setting: MSB
  • Specification of data timing: Type 1
  • Transfer rate setting – Clock mode: Internal clock (master)
  • Transfer rate setting – Baudrate: 1000000 (bps)
  • Interrupt setting – Transfer interrupt priority (INTCSI10): Low
  • Uncheck the callback functions.

TM00 (Timer 00) – For the DelayMs() function

Configure TM00 as an interval timer:

  • Interval timer setting - Interval value(16 bits): 1 ms
  • Interval timer setting - Uncheck Generates INTM00 when counting is started
  • Interrupt setting - Uncheck End of timer channel 0 count, generate an interrupt (INTM00)

Watchdog Timer

Disable the watchdog timer:

  • Choose for the Watchdog timer operation setting: Unused option.

Reference Project Overview

The reference project runs an offset correction operation, configures the REC_CTRL register and initiates a Manual Time recording. After the process is finished on the LCD are displayed the internal temperature, the power supply voltage and the first value of each axis's buffer.

Software Project Setup

This section presents the steps for developing a software application that will run on the Renesas Demo Kit for RL78G13 for controlling and monitoring the operation of the ADI part.

Two software applications have to be used: Applilet3 for RL78G13 (a tool that automatically generates device drivers for MCU peripheral functions) and IAR Embedded Workbench for Renesas RL78 (the integrated development environment).

Step 1 - Applilet3 for RL78G13

  • Run the Applilet3 for RL78G13 tool and create a new project for R5F100LE processor. Select IAR Compiler build tool, a project name, a location for the new project and press OK.

  • Keep the default Pin assignment setting and click Fix settings.

  • Now the desired peripherals can be configured and the code can be generated. For example, if the clocked serial interface 10 (CSI10) has to be configured, select the Serial peripheral, choose for the Channel 2 of Serial Array Unit 0 (SAU0) the CSI10 interface, Transmit/receive function option and then go to CSI10 tab.

  • To configure the CSI10 interface for serial transmissions of 8 bits, with MSB first, with the data captured on clock's rising edge, with a frequency of the clock of 1 MHz and the idle state high, the settings from the following image have to be made.

  • After all the desired peripherals are configured click on the Generate Code button and a new workspace and a new project for the IAR Embedded Workbench will be generated. After the code was generated close the Applilet3 for RL78G13 tool.

Step 2 - IAR Embedded Workbench for Renesas RL78

  • Run the IAR Embedded Workbench and open the workspace created with the Applilet3 tool.

  • Copy the files extracted from the zip file into the user_src folder, located in the project’s folder.

  • The new source files have to be included into the project. Add in the user_src group the files from the corresponding folder (Right click on the group and select Add – Add Files…). Because a new Main file was included the r_main.c file from the applilet_src group has to be deleted (Right click on the file and select Remove).

  • Now the debugger driver has to be selected from the project’s options. Right click on the project name and select Options. From the Debugger category choose the TK Debugger Driver.

  • Now, the project is ready to be compiled and downloaded on the board. Press the F7 key to compile it. Press CTRL + D to download and debug the project.
