Chapter 1. Product Overview

1.1 OVERVIEW

The MCP3919 ADC Evaluation Board for 16-Bit MCUs system provides the opportunity to evaluate the performance of the MCP3919 three-channel Analog Front End (AFE). It also provides a development platform for 16-bit microcontroller-based applications, using the existing 100-pin PIC® microcontroller Plug-in Module (PIM) systems that are compatible with the Explorer 16 Evaluation Board (DM240001) and other high pin count PIC device based demo boards. The system comes with a programmed PIC24FJ256GA110 PIM module that communicates with the Energy Management Utility software for data exchange and ADC setup.

The MCP3919 ADC Evaluation Board for 16-Bit MCUs uses the Energy Management Utility software for evaluation of the MCP3919 via a USB connection to the board. A download link for this software can be found on the evaluation board’s web page. For instructions on the use of this software, refer to the supporting documentation included within the application install package.

1.1.1 Feature Highlights

• Three-channel ADC MCP3919 output display using serial communication to the PC software interface.

• Simultaneous 57 ksps at OSR32 address loop ALL or 95 dB SINAD at OSR512 performance on MCP3919.

• System and ADC performance analysis through graphical PC tools showing noise histogram, frequency domain (FFT), time domain scope plot and statistical numerical analysis.

• Robust hardware design with analog grounding and analog/digital separation, allowing low noise evaluation of the MCP3919 device; includes separate power supplies and power planes on a four-layer board.

• PICtail™ Plus connectors for Explorer 16 daughter board compatibility.

Hardware Description

Ports A, D and G are used for signals such as push buttons, output LEDs, CS and MCLR (for the MCP3919 data mode setting). Output Compare 1 is used for clock generation in the MCP3919. Serial communication is achieved through the MSSP module 1.

The MCP3919 device is an Analog Front End (AFE) with three ADCs featuring a sec-ond order modulator and a third order sinc filter, plus a first order sinc filter used for higher OSR values. The delta-sigma A/D converters have an adjustable oversampling ratio. The CLKIN pin of the MCP3919 is the oversampling clock (MCLK) input. The MCP3919 ADC Evaluation Board for 16-Bit MCUs offers two different options for the MCP3919 master clock (MCLK). The default setting for the ADC internal clock is an external clock driven by the MCU.

2.1.1 Using the Crystal X1

The MCP3919 ADC Evaluation Board for 16-Bit MCUs is populated with a 10 MHz crystal, used as a clock source by placing jumpers in the following position on the MCP3919 Digital I/O header block:

FIGURE 2-2: ADC Clock Selection Jumpers – External Crystal.

2.1.2 Driving the Clock with the PIM Module

The PIC MCU can be used to generate the CLKIN (MCLK) signal for the MCP3919, setting the ADC sample rate through the use of the output compare module OC1. To use this feature, make the following jumper change to the MCP3919 Digital I/O header block:

FIGURE 2-3: ADC Clock Selection Jumpers – Clock from MCU.

The frequency of the OC1 output is based on the PR1 bit settings in the firmware.

2.2 ANALOG INPUT STRUCTURE

Three differential input paths allow external signal sources to be easily connected to the MCP3919 inputs. Screw-terminal connectors J1, J4, J7, J21, J23, J25, J27 and J29 are 3-pin connectors that act as both screw-type and clip-on post connectors.

The connectors J1, J4, J7, J21, J23 and J25 can be used to force either channel from a differential to single-ended configuration. R4 and R11 (on CH0), R19 and R21 (on CH1) R18 and R65 (on CH2), R69 and R71 (on CH3), R75 and R77 (on CH4) and R81 and RR83 (on CH5) act as locations for burden resistor connectors for any current transformer inputs.

2.3 UNIVERSAL SERIAL BUS (USB)

The MCP3919 ADC Evaluation Board for 16-Bit MCUs also contains a USB connection for connecting the evaluation board to a PC. There is an MCP2200 USB to UART con-verter on the board which creates a virtual COMM port on the PC. The MCP3919 ADC Evaluation Board for 16-Bit MCUs also features an RS-232 connector, just in case it is required. The RS-232 line driver is connected to the same UART pins of the MCU. For this reason, a 3-pin jumper (J16) is present on the evaluation board to select which serial communication will be used: USB or RS-232. The following figure summarizes the con-nections between the ADC, MCU, USB to serial converter and the RS-232 line driver.

FIGURE 2-4: USB Block Diagram.

The MCP2200 is powered from the USB with 5V. The Q1 transistor (see Appendix A. “Schematics and Layouts”) is used to disconnect the board from the PC when it is powered-down to avoid power consumption. By changing the jumper J9 setting, the user can select the source of the power supply for the board to be either +5V derived from the USB or an external +9V power supply.

Since the PIC24F runs at 3.3V, a level shifter was used to modify the signal level to 5V as required by the MCP2200; this is done with U11 (see Appendix A. “Schematics and Layouts”).

The 7.3728 MHz value of the crystal is required to achieve the correct baud rate values for higher speed. This design uses a baud rate of 921.6 kbaud and for this baud rate, the register (U1BRG) value is 3 (decimal).

Chapter 3. Firmware

3.1 PIC24FJ256GA110 FIRMWARE DESCRIPTION

3.1.1 MCU Initialization

The microcontroller used for the code example is the 16-bit XLP with 16 MIPS PIC24FJ256GA110. The MCU has remappable pins and output compare with a dedicated time base.

The MCU uses a 7.3278 MHz crystal for the clock and the internal PLL to increase the frequency by four times. The uncommon crystal value was chosen to obtain the correct baud rate, even for high baud rates. The remappable pins are configured to make the PIM compatible with the Explorer 16 development board. The MCP3919 is linked with the MCU through the SPI1 port. The ADC clock is given by OC1. The DR pin of the MCP3919 is tied to external Interrupt 2.

Serial data transmission is carried out through the UART2 module. For transmission, OC2 interrupt is used; for receiving, the _U1RX Interrupt is used. The UART communi-cation speed is 921.6 kbaud. OC2 is used for the serial transmission to create short bursts of data that can be processed by the MCP2200. Sending too many characters, with no time between them at the current baud rate, will cause the MCP2200 to lose data.

3.2 DATA ACQUISITION

External Interrupt 2 is used for detecting the end of conversion on the MCP3919. In the INT2 Interrupt, the data samples are read from the ADC using SPI.

When a new buffer begins to be read, Timer 4 is started. This is set as a 32-bit timer together with Timer 5. It will be stopped when the buffer is full and is used to measure the sampling speed.

Before reading the date samples, the MCU investigates the address loop setting (READ <1:0> bits) in the STATUSCOM register and adjusts the read sequence accord-ingly (when the address is not incremented automatically in hardware, the MCU has to do that in firmware, leading to a longer read sequence). The acquired samples are written in three long vectors created in the RAM of the MCU. The three vectors hold the first, second and third byte from both channels.

The vectors have a length of 2048. The value of Timer 4 and the values of the other registers inside the ADC are stored in a vector called “internal_registers[26]”.

Note: The PIC24FJ256GA110 must be Rev. A5 or newer in order for this code example to work.



3.3 UART COMMUNICATION PROTOCOL

The serial connection is used to send the acquired data to the PC at a speed of 921.6 kbaud, and the MCP2200 is used for the UART-to-USB conversion.

The communication uses handshaking, meaning that the board will not send data to the PC unless the board receives a command from the PC.

The UART transmission is triggered by the output compare module OC2.This allows the data to be transmitted to the PC in short bursts that are separated by a dead time. This method of sending data allows the MCP2200 to handle the high throughput. If the entire amount of data is sent continuously to the PC at the current baud rate, the MCP2200 will not be able to process the data for correct USB transfer.

After a complete transmission, the UART RX interrupt is enabled by increasing its priority relative to all other interrupts. In this interrupt, the MCU needs to receive the values of the internal registers as the user is setting them in the PC GUI.
