Pixxi Display Modules

What is the maximum baud rate I can achieve with a Pixxi display module?

Pixxi display modules support up to 2M Baud.

Is 1-Wire supported by Pixxi modules?

No, it does not support Dallas One-Wire.

Does Pixxi processor support 8-bit images?

No, it does not. The Pixxi processor only supports 16-bit images.

Can I save my variables in to the internal flash of a Pixxi processor?

No, you can't. If you want to save information permanently, you should save it to a microSD card or Flash chip.

I'm out of program space in my Pixxi display, what can I do?

You can try utilizing 4FN and 4XE files. These will allow you to compile 4DGL code and save them to the microSD. These files can be called/run when needed by your main program.

Can I access folders in the FAT formatted microSD card using Pixxi?

No, you cannot use folders in the microSD card with the Pixxi based display modules. Files are only accessible from the root folder.

Is it recommended to download/run the 4DGL program from the RAM during Pixxi development stages?

Yes, it is desirable to download/run the program from RAM to eliminate unnecessary FLASH write cycles.

Does Pixxi display modules support SPI?

No. Pixxi graphics processor doesn't support SPI besides the dedicated SPI bus for microSD / Flash.

Does Pixxi display modules support I2C?

Yes. Pixxi display modules support I2C. However, it only supports I2C Master mode. The display can't behave as an I2C slave.

Does Pixxi display modules support RS232?

No. Pixxi display modules do not directly support RS232. However, you can use MOTG-RS232 or similar modules to connect a Pixxi display via RS232.

To connect a MOTG-RS232 to a Pixxi display, you can use a MOTG-Breadtooth and a gen4-Breakout.

Using a MOTG-RS232 will require the only COM port of the Pixxi module which is also used in programming the display and a GPIO pin. Therefore, the MOTG-RS232 needs to be disconnected before uploading a project to the display module.

Does Pixxi display modules support RS485?

No. Pixxi display modules do not directly support RS485. However, you can use MOTG-RS485 or similar modules to connect a Pixxi display via RS485.

To connect a MOTG-RS485 to a Pixxi display, you can use a MOTG-Breadtooth and a gen4-Breakout.

Using a MOTG-RS485 will require the only COM port of the Pixxi module which is also used in programming the display and a GPIO pin. Therefore, the MOTG-RS485 needs to be disconnected before uploading a project to the display module.

Does Pixxi display modules support CANBUS?

No. Pixxi display modules do not directly support CANBUS.

Can I use a higher capacity microSD card with Pixxi displays?

Yes. You should be able to use a microSD card higher than 4GB.

However, keep in mind that Pixxi display only supports FAT16 which have a maximum of 4GB space. The rest of the unused space on the SD card can be accessed as RAW.

You will need to format the SD card appropriately using RMPET.

To use this tool:

  • Open or create a new Workshop4 project
  • Go to Tools menu and open RMPET
  • Follow the instructions provided by the tool
Widgets don't show in flash-mode Pixxi display. How can this be fixed?

GCI and Inherent widgets are stored to the onboard flash when using Pixxi in flash mode.

If these widgets don't show, it is possible that the file transfer doesn't work properly. This is often due to a driver issue.

You might want to check and update the driver. When installing, be sure to:

  • Uninstall the old driver first via Device Manager
  • Disconnect the programmer from the PC
  • Install the new driver
  • Reconnect the Programmer

Here's what we recommend:

If this doesn't work, you can try one of the following:
