ADT7420 - No-OS Driver for Renesas Microcontroller Platforms
Supported Devices
Evaluation Boards
Overview
The ADT7420 is a high accuracy digital temperature sensor offering breakthrough performance over a wide industrial range, housed in an LFCSP package. It contains a band gap temperature reference and a 13-bit ADC to monitor and digitize the temperature to a 0.0625°C resolution. The ADC resolution, by default, is set to 13 bits (0.0625°C). This can be changed to 16 bits (0.0078°C) by setting Bit 7 in the configuration register to 1 (Register Address 0x03). The ADT7420 is guaranteed to operate over supply voltages from 2.7 V to 5.5 V. Operating at 3.3 V, the average supply current is typically 210 μA. The ADT7420 has a shutdown mode that powers down the device and offers a shutdown current of typically 2 μA. The ADT7420 is rated for operation over the ?40°C to +150°C temperature range.
Pin A0 and Pin A1 are available for address selection, giving the ADT7420 four possible I2C addresses. The CT pin is an open-drain output that becomes active when the temperature exceeds a programmable critical temperature limit. The default critical temperature limit is 147°C. The INT pin is also an open-drain output that becomes active when the temperature exceeds a programmable limit. The INT and CT pins can operate in either comparator or interrupt mode.
Applications
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 different microcontroller platforms.
Driver Description
The driver contains two parts:
- The driver for the ADT7420 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 ADT7420 driver can be used exactly as it is provided.
There are three functions which are called by the ADT7420 driver:
- I2C_Init() – initializes the communication peripheral.
- I2C_Write() – writes data to the device.
- I2C_Read() – reads data from the device.
I2C driver architecture
The implementation of these three functions depends on the used microcontroller.
The following functions are implemented in this version of ADT7420 driver:
| Function | Description |
|---|---|
| unsigned char ADT7420_GetRegisterValue(unsigned char registerAddress) | Reads the value of a register. |
| void ADT7420_SetRegisterValue(unsigned char registerAddress, unsigned char registerValue) | Sets the value of a register. |
| char ADT7420_Init(void) | Initializes the comm. peripheral and checks if the device is present. |
| void ADT7420_Reset(void) | Resets the ADT7420. |
| void ADT7420_SetOperationMode(unsigned char mode) | Sets the operational mode for ADT7420. |
| void ADT7420_SetResolution(unsigned char resolution) | Sets the resolution for ADT7420. |
| float ADT7420_GetTemperature(void) | Reads the temperature data and converts it to Celsius degrees. |

Reference Project Overview
Software Project Setup
This section presents the steps for developing a software application that will run on the Renesas Demo Kit for RX63N for controlling and monitoring the operation of the ADI part.
- Run the High-performance Embedded Workshop integrated development environment.
- A window will appear asking to create or open project workspace. Choose “Create a new project workspace” option and press OK.
- From “Project Types” option select “Application”, name the Workspace and the Project “ADIEvalBoard”, select the “RX” CPU family and “Renesas RX Standard” tool chain. Press OK.
- A few windows will appear asking to configure the project:
- In the “Select Target CPU” window, select “RX600” CPU series, “RX63N” CPU Type and press Next.
- In the first “Option Setting” window change only the Precision of double from single to “Double precision” and press Next.
- In the second “Option Setting” window keep default settings and press Next.
- In the “Setting the Content of Files to be generated” window select ”None” for the ”Generate main() Function” option and press Next.
- In the “Setting the Standard Library” window press “Enable all” and then Next.
- In the “Setting the Stack Area” window check the “Use User Stack” option and press Next.
- In the “Setting the Vector” window keep default settings and press Next.
- In the “Setting the Target System for Debugging” window choose “RX600 Segger J-Link” target and press Next.
- In the “Setting the Debugger Options” and “Changing the Files Name to be created” windows keep default settings, press Next and Finish.
- The workspace is created.
- The RPDL (Renesas Peripheral Driver Library) has to integrated in the project. Unzip the RPDL files (double-click on the file “RPDL_RX63N.exe”). Navigate to where the RPDL files were unpacked and double-click on the “Copy_RPDL_RX63N.bat” to start the copy process. Choose the 100 pins package and little endian option, type the full path where the project was created and after the files were copied, press any key to close the window.
- The new source files have to be included in the project. Use the key sequence Alt, P, A to open the “Add files to project ‘ADIEvalBoard’” window. Double click on the RPDL folder. From the “Files of type” drop-down list, select “C source file (*.C)”. Select all of the files and press Add.
- To avoid conflicts with standard project files remove the files “intprg.c” and “vecttbl.c” which are included in the project. Use the key sequence Alt, P, R to open the “Remove Project Files” window. Select the files, click on Remove and press OK.
- Next the new directory has to be included in the project. Use the key sequence Alt, B, R to open the “RX Standard Toolchain” window. Select the C/C++ tab, select “Show entries for: Include file directories” and press Add. Select “Relative to: Project directory”, type “RPDL” as sub-directory and press OK.
- The library file path has to be added in the project. Select the Link/Library tab, select “Show entries for: Library files” and press Add. Select “Relative to: Project directory”, type “RPDL/RX63N_library” as file path and press OK.
- Because the “intprg.c” file was removed the “PIntPrg” specified in option “start” has to be removed. Change “Category” to “Section”. Press “Edit”, select “PIntPRG” and press “Remove”. From this window the address of each section can be also modified. Set the second address to 0xFFF00000 and the third one to 0xFFF00100. After all the changes are made press OK two times.
- At this point the files extracted from the zip file located in the “Software Tools” section have to be added into the project. Copy all the files from the archive into the project folder.
- Now, the files have to be included in the project. Use the key sequence Alt, P, A to open the “Add files to project ‘ADIEvalBoard’” window. Navigate into ADI folder. From the “Files of type” drop-down list, select “Project Files”. Select all the copied files and press Add.
- Now, the project is ready to be built. Press F7. The message after the Build Process is finished has to be “0 Errors, 0 Warnings”. To run the program on the board, you have to download the firmware into the microprocessor’s memory.
