Introduction

This Application Note provides a guide on how to connect the 7'' EDT display to PHYTEC phyBOARD-Mira Voice Control Kit via the PEB-AV-07 Display Adapter. An example is given to describe all steps necessary to connect the 7'' EDT display and to enable the display configuration in barebox, as well as to operate the software implemented on the phyBOARD.

Requirements

The following system requirements are necessary to successfully complete this Application Note. Deviations from these requirements are possible but may require the use of workarounds.

Hardware

  • phyBOARD-Mira i.MX 6 Voice Control Kit (KPB-01501-010) (PEB-AV-07 A/V Adapter is included)
  • 40 Pins FFC flex flat cable (WF061)
  • 7'' EDT display (AC158)
  • Power supply 12 V – 24 V DC[1]

Software

  • phyBOARD-Mira i.MX 6 – 1.0 or newer (for AC158)

1. 1

The supply voltage required depends on the phyBOARD you are using and any additional expansion boards or displays connected to it. Various configurations might require a higher or lower supply voltage than the specified value. E.g. if only the display adapter is connected to the phyBOARD‑Mira, the current consumption is around 100 mA at 24 V via the PEB-POW-01 (Power Module), and around 400 mA at 5 V connected directly to the 2-pole Phoenix Contact MINI COMBICON on the phyBOARD.


Warning

Be sure to select the appropriate power supply for your phyBOARD-Mira. phyBOARD-Mira delivered with the PEB-POW-01 (Power Module) requires a 12 V – 24 V DC (min. 1 A)1 power supply connected to the 2-pole Phoenix Contact MINI COMBICON base strip on the PEB-POW-01.
For details, please refer to the QuickStart Guide of your phyBOARD-Mira Kit.

Connecting the Display

  1. Connect one end of the FFC flex flat cable to the underside of the 7'' EDT display (AC158). There is a delicate clamp you need to pull up slightly before sliding the cable in.

    Warning

    Be very careful when inserting the cable into the display connector and the PEB-AV-07 adapter. This kind of display connector is easy to break if you use force!

  2. The clamp on the PEB-AV-07 voice recognition adapter pulls straight out to open the clamp. After inserting the cable, the clamp can then be pushed in to lock the cable in place.

  3. Turn the display over. Connect the other end of FFC flex flat cable to PEB-AV-07 display adapter. The cable clamp needs to be pulled up at a 90°angle to open.  After inserting the cable, push down on the clamp to lock it.

    If you are using a phyBOARD-Mira i.MX 6 (PB-01501-xxxx), the display adapter needs to be plugged into the carrier board from the opposite side (from the bottom)!

  6. Connect the RS-232 cable between your host PC and the phyBOARD-Mira debug adapter.

  7. Start your favorite terminal software (e.g. Minicom, or Tera Term) on your host PC and configure it for 115200 baud, 8 data bits, no parity, 1 stop bit (8n1) and no handshake.
  8. Connect the power supply to the power connector.

BSP Setup

The BSP has already been configured to support the display but it must be enabled as an expansion by editing the file config-expansions in the barebox environment. Please refer to the Yocto phyBOARD-Mira BSP Manual (L-814e.A4) for more information.

  1. Open file config-expansions with:

    bootloader$ edit /env/config-expansions 
  2. Change the comments of the following 2 lines from:

    #. /env/expansions/im6-phytec-mira-peb-av-07
    /env/expansions/mira.hdmi

    to:

    /env/expansions/mira-peb-av-07
    #. /env/expansions/mira-hdmi
  3. Save and exit the configuration file using CTRL+D and save the environment:

    bootloader$ saveenv
  4. Restart the board, and watch the boot. The login prompt will be shown at the end of the booting process:
