UDP SiM3U1xx 3.3. CP210x USB to UART VCP Driver Installation The MCU card includes a Silicon Labs CP210x USB-to-Dual-UART Bridge Controller. Device drivers for the CP210x need to be installed before the PC software can communicate with the MCU through the UART interface. If the "Install CP210x Drivers" option is selected during installation, a driver “unpacker” utility will launch. 1. Follow the steps to copy the driver files to the desired location. The default directory is C:\SiLabs\MCU\CP210x. 2.
UDP SiM3U1xx 4. UDP SiM3U1xx MCU Card Overview The SiM3U1xx MCU card enables application development on the SiM3U1xx MCU. The card connects to the MCU Card expansion slot on the UDP motherboard and provides complete access to the MCU resources. Each expansion board has a unique ID that can be read out of an EEPROM or MCU on the board, which enables software tools to recognize the connected hardware and automatically select the appropriate firmware image.

UDP SiM3U1xx 4.2. Analog Terminals (H1) Several of the SiM3U1xx port pins used for analog functions are connected to the H1 terminal block. Refer to Table 1 for the H1 terminal block connections. Table 1. Terminal Block Pin Descriptions (H1) Pin I/O 1 2 3 4 5 6 PB0.12 / VREF PB0.11 / VREFGND PB1.5 / ADCn.14 PB1.6 / ADCn.15 PB0.13 / IDAC0 GND 4.3. User Control Switch (SW4) The User Control Switch enables and disables the User Control portion of the board.
UDP SiM3U1xx 4.6. Power LEDs (DS1, DS2) The two power LEDs provide visual feedback when the board is powered. When the System Power Select Switch is in the USB position, the PWR USB LED (DS1) will turn on when the device is powered over USB or by connecting a power supply to any power header on the board. When the System Power Select Switch is in the MB position, the PWR MB LED (DS2) will turn on when the device is powered by a UDP Motherboard. 4.7.
UDP SiM3U1xx 4.12. Capacitive Sensing Button and Slider (S1) Two capacitive sensing buttons and one slider are included on the MCU card. Six GPIO pins are connected to the slider and can be used to implement up to two buttons or a slider. Table 5 shows the J13 pin definitions. The GPIO pins are connected to the slider in ascending order from the location labeled “A” to the location labeled “B” on the MCU card. Table 5. Capacitive Sensing GPIO Connections Location Pin A — — — — B PB1.7 PB1.8 PB0.4 PB0.
UDP SiM3U1xx 4.15. MCU Card Default and Optional Connections The MCU card has many default and optional connections for use with different I/O cards and the UDP motherboard. The default connections are via shorting jumpers. The shorting jumpers are a 603 resistor footprint with a cut trace between pads. To disconnect, cut the trace with a sharp utility knife. To reconnect, install a 0 603 resistor or connect the two pads with solder. The optional connections are non-populated (no-pop) resistor footprints.

Current Measurement The power measurement circuitry on the UDP motherboard consists of a Silicon Labs C8051F351 8051 MCU that measures both input voltage and current consumption of the MCU card, I/O expander, and radio test card. Install a shorting block on the UDP Motherboard J13 and J15 connecting the two left pins together when using the motherboard with the SiM3U1xx MCU card.
UDP SiM3U1xx 5.3. Shorting Blocks: Factory Defaults The UDP SiM3U1xx MCU card comes from the factory with pre-installed shorting blocks on several headers. Figure 8 shows the positions of the factory default shorting blocks. Figure 8. Shorting Blocks: Factory Defaults Shorting blocks are installed across the USB (J14), VDD (J15), VIO (J17) Imeasure jumpers. A shorting block is installed on J16 to connect the potentiometer to the User Control portion of the board.
