The BIGdsPIC6 development system provides a DIMM-168P connector to place an MCU card into. This development system comes
with an MCU card with a microcontroller in 80-pin TQFP package soldered on it, Figure 2-3. Besides, the MCU card alone provides an
oscillator as well as 80 soldering pads connected to the microcontroller pins. Each pad is marked the same as the pin it is connected
to. Soldering pads also make connection between the MCU card and target device’s modules easy.

The ICD connector enables communication between the microcontroller and an external ICD debugger/programmer (ICD2 or ICD3)
from Microchip. Jumpers J14 and J15 are used for selecting the pin to be fed with programming signal. For the programming signal to
be sent to the microcontroller, it is necessary to place both jumpers in the same position, as shown in Figure 4-3. Either RB0 and RB1
or RB6 and RB7 microcontroller pins can be fed with this signal. The position of jumpers J14 and J15 depends on the microcontroller
provided on the MCU card. When the dsPIC30F6014 microcontroller is programmed by means of the external ICD programmer,
jumpers J14 and J15 should be placed in the RB0 and RB1 position, respectively. In case some other microcontroller is used, it is
necessary to check which microcontroller pins can be fed with the programming signal.

6.0. A/D Converter Test Inputs
An A/D converter is used for converting an analog voltage into the appropriate digital value. The A/D converter is linear, which means
that converted number is linearly dependent on the input voltage value. The A/D converter built into the microcontroller converts an
analog voltage value into a 10-bit number. Potentiometers P3 and P4 enable voltage to vary between 0 and 5V. The microcontroller
with a built-in A/D converter is supplied with this voltage via test inputs. Jumpers J16 and J17 are used for selecting one of the
following pins RB8 - RB15 to be supplied with A/D conversion voltage. Resistors R28 and R29 have a protective function and are used

The MMC/SD connector enables the memory card to be interfaced to the microcontroller in order to expand microcontroller memory.
To enable serial communication between the microcontroller and the memory card it is necessary to adjust their voltage levels.
Memory card is powered with the 3.3V power supply voltage (VCC-MMC) generated by the REG1 voltage regulator, whereas the
value of the microcontroller power suplly voltage is 5V (VCC). A bus transceiver 74LVCC3245 is used here to adjust these voltage
levels. In addition, in order to establish communication between memory card and microcontroller, it is necessary to set switches 6, 7

USART (8QLYHUVDO6\QFKURQRXV$V\QFKURQRXV5HFHLYHU7UDQVPLWWHU) is one of the most common ways of exchanging data between
the PC and peripheral units. RS-232 serial communication is performed through a 9-pin SUB-D connector and the microcontroller
USART module. The BIGdsPIC6 provides two RS-232 ports, RS-232A and RS-232B. Use switches RX232-A and TX232-A on the DIP
switch SW14 to enable port RS-232A. Likewise, use switches RX232-B and TX232-B on the DIP switch SW14 to enable port RS-232B.
The microcontroller pins used in such communication are marked as follows: RX - UHFHLYHGDWDOLQH and TX -WUDQVPLWGDWDOLQH. Data
rate goes up to 115 kbps.
In order to enable the USART module of the microcontroller to receive input signals with different voltage levels, it is necessary to
adjust these levels using an IC circuit such as MAX202 (MAX232).

CAN (Controller Area Network) is a communication standard primarily intended for use in automotive industry. It enables the
microcontroller to communicate to a car device without using a host PC. In addition, such communication is widely used in industrial
automation. The BIGdsPIC6 uses the MCP2551 circuit for CAN communication. This circuit provides an interface between the
microcontroller and some peripheral device. To enable connection between the microcontroller and MCP2551, it is necessary to set
switches 5 and 7 on the DIP switch SW14 to the ON position. Switches 6 and 8 on the DIP switch SW14 may also be used for this
purpose. Which of these switches is to be used depends solely on the arrangement of the microcontroller pins connected to CAN
communication lines. The RX line is connected to the microcontroller via RG0 and RF0 microcontroller pins, whereas the TX line is
connected to the microcontroller via RG1 and RF1 microcontroller pins.

The USB UART module is used to connect the microcontroller provided on the development system to external USB devices. The
USB UART module features the FT232RL circuit providing an interface between the USB device and serial UART module integrated
into the microcontroller. In order to establish connection between the microcontroller and USB UART module, it is necessary to set
switches 1 (RF2) and 2 (RF3) on the DIP switch SW12 to the ON position.
When connecting a UART device and the microcontroller, it is necessary to cross connect data send and data receive lines. In other
words, the UART’s RX pin should be connected to the microcontroller’s TX pin, while the TX pin should be connected to the RX pin.
It is not possible to directly connect UART’s and microcontroller’s TX lines since the microcontroller wouldn’t be able to receive nor
send data.
