-The [[adi>AD7980]] is a 16-bit, successive approximation, analog-to-digital converter (ADC) that operates from a single power supply, VDD. It contains a low power, high speed, 16-bit sampling ADC and a versatile serial interface port. On the CNV rising edge, it samples an analog input IN+ between 0 V to REF with respect to a ground sense IN−. The reference voltage, REF, is applied externally and can be set independent of the supply voltage, VDD. Its power scales linearly with throughput.+====== Renesas RL78G13 Quick Start Guide ====== 
 +This section contains a description of the steps required to run the AD7980 demonstration project on a Renesas RL78G13 platform.

-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.+==== Required Software ====

-===== Driver Description ===== +{{ :resources:tools-software:uc-drivers:renesas:pmod_ad4_rl78g13.jpg? |}}
-The driver contains two parts: +
-  * The driver for the AD7980 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 AD7980 driver can be used exactly as it is provided.+<WRAP round important round 80%> 
 +\\ 
 +  * If you want to use AVDD > DVDD (= 3.3V) then JP3 on PmodAD4 must be removed. The range for AVDD is 3.0V ≤ AVDD ≤ 5.5V. 
 +\\

-There are three functions which are called by the AD7980 driver: +==== Reference Project Overview ====
-  * SPI_Init() – initializes the communication peripheral. +
-  * SPI_Write() – writes data to the device. +
-  * SPI_Read() – reads data from the device.+

 + 
 +<WRAP round important 80%> 
 +  * The reference voltage for the AD7980 is 2.5V. 
 +  * If you want to use another reference voltage, you will need to modify the vRef parameter in ‘AD7980_ConvertToVolts()’ function from ‘PmodAD4.c’. The range for VREF is 2.4V ≤ VREF ≤ 5.1V.
