+##  ADC Sampling at 1.1MSPS 
+
+This file contains the following sections:
+- Code Example Description
+- Suggested Development Resources
+- Reconfiguring the project for a different dsPIC33E device
+- Revision History
+
+
+## Code Example Description:
+
+In this example, ADC is set up to convert AIN0 using CH0 and CH1 sample/hold in 10-bit sequential mode 
+at 1.1MHz throughput rate. ADC clock is configured at 13.3Mhz or Tad=75ns
+ADC Conversion Time for 10-bit conversion is Tc=12 * Tab =  900ns (1.1MHz).
+
+void initAdc1(void);
+ADC CH0 and CH1 S/H is set-up to covert AIN0 in 10-bit mode. ADC is configured to next sample data immediately after the conversion.
+So, ADC keeps conversion data through CH0/CH1 S/H alternatively. Effective conversion rate is 1.1Mhz
+
+void initDma0(void);
+DMA channel 0 is configured in ping-pong mode to move the converted data from ADC to DMA RAM on every sample/convert sequence. 
+It generates interrupt after every 16 sample transfer. 
+
+void __attribute__((__interrupt__)) _DMA0Interrupt(void);
+DMA interrupt service routine, moves the data from DMA buffer to ADC signal buffer and collects 256 samples.
+
+The Toggle frequency of one pulse should be around 240us(micro second), if the operating clock frequency at 40Mhz.
+Short AN0/AN1 with +3.3v to get analog signal for sampling. These values should be approximately around 0x7FXXX when checked in the bufferA/bufferB in the code.
+
+
+## Hardware Used
+
+- Explorer 16/32 Development Board (https://www.microchip.com/DM240001-2)
+- dspic33ep512gm710(https://www.microchip.com/ma330035) /dspic33ep512mu810 (https://www.microchip.com/MA330025-1)/ dspic33ep256gp506 (https://www.microchip.com/MA330030) PIM
+	
+	
+## Software Used 
+
+- MPLAB® X IDE v5.50 or newer (https://www.microchip.com/mplabx)
+- MPLAB® XC16 v1.70 or newer (https://www.microchip.com/xc)
+
+## Reconfiguring the project for a different dsPIC33E device:
+
+The Project/Workspace can be easily reconfigured for dspic33ep512gm710/dspic33ep512mu810/dspic33ep256gp506 device.
+Please use the following general guidelines:
+
+a. Change device selection within MPLAB® IDE to dspic33ep512gm710/dspic33ep512mu810/dspic33ep256gp506 device of
+   your choice by using the following menu option:
+   MPLAB X>>Configuration drop-down option>><Listed Device Configuration>
+
+b. Re-build the MPLAB® project using the menu option:
+   MPLAB X>>Build Main Project
+
+c. Download the hex file into the device and run.
+
