Step 1: Connect Hardware

Step 1.1: Attach PAC1934 Click board™

  • Attach the PAC1934 Click board™. The PAC1934 Integrated Circuit (IC) has specialized hardware to make meter measurements and accept commands from the microcontroller (MCU)

Step 1.2: Attach OLED W Click


Attach the OLED W Click board to mikroBUS™ 2 for displaying meter measurements

Step 1.3 Connect USB and Ethernet from ATSAMA5D27-SOM1-EK1 to PC Host

  • Connect a USB Type-A to Micro B cable from the PC Host to J-Link-OB micro-USB port (J10). This port is configured for serial communication to the host processor’s console
  • Connect Ethernet cable RJ45 (J15) from the board to PC Host. Having Ethernet connection from the computer makes it easier to transfer files to and from this board

Step 1.4 Verify Jumper Settings

  • J22 – Shorted (Enable 3v3 on MBUS1)
  • J28 – Shorted (Enable 3V3 on MBUS2)
  • J13 – Open (Disables System on Module (SOM) boot memories, closed = disable)
  • J7 – Open (Enable J-Link-OB for serial communication, closed = disable)
  • J9 – Open (Enable J-Link CDC, closed = disable)

Step 1.5 Prepare SD Card for the Embedded Linux® image

  • SD card requirements: 2 Gigabytes or more SD (Secure Digital) card. This non-volatile memory card is used to store the Linux® Image

Step 1.6 Connect a 5V Power Supply to the PAC1934 Click

  • Connect the 5V power supply to PAC1934 Click S1+, S2+, S3+ and S4+ pins as shown
  • Connect Ground to PAC1934 Click GND pin as shown

Step 1.7 Attach Four 47 Ω Resistors from PAC1934 Click Board to Ground

  • Connect each 47 Ω resistor to PAC1934 Click S1, S2, S3 and S4 pins as shown
  • Connect resistors to a common ground
