Hello Tim, Thank you for posting on the forum. By any chance you opened the Debug View (to the right of the 'X') in the Support Tool? You will only see the replies using the Debug View window. As for 'A' and 'B', there was a mention regarding this on the older manual , but since we have added altern...

Hello Aviral, Thank you for posting on the forum. I have replied to your enquiry directly, but I will also post it here. The quickest way to check the EVE3-50A-TPN hardware is to connect to the PC via the USB2SPI bridge. Try this demo out: https://github.com/MatrixOrbital/Basic-EVE-Demo As for your ...

Hello Eddi,

Thank you for posting on the forum.

Are you able to test out the power coming from the USB2SPI bridge?
Can you please check it using a scope?
Can you also try supplying external power via the barrel jack? Center positive, 5V-12V 1A if you have it.

Thank you,
Raquel

Hello, Thank you for posting on the forum. SCL/SDA lines on the GLK12232A-25-SM-GW-VS, although configurable for use as I2C pins, has this mention on the datasheet: "this is not an I2C-bus compliant open-drain pin". Is it possible that you may have connected the SCL lines to either GND or ...

Hi Alex,

Thank you for posting on the forum.

Matrix Orbital EVE3 series use the W25Q128JVSIM flash.
Together with our USB bridge EVE2-USB2SPI-KIT-A, and EVE's Asset Builder you can easily detect, erase and program the flash.

Best Regards,

Hello Tuomas,

Thank you for posting on the forum.

We have not had experience with Mbed OS, unfortuantely.
But please do check our EVE sample for the STM32-Nucleo-F104RE, hopefully it can give you some guidance:

Hello ldcaseIII, Thank you for posting on the forum. Your are right, we do not have a complete listing of GTT25 command responses. We only chose to document the most important ones. You may please check our client library from here: https://github.com/MatrixOrbital/MatrixOrbitalGTTClientLibrary You ...

Hello, You mentioned that "One of the units is also being powered via the barrel jack in addition to the USB connection" I imagine the one that is not powered is the one that is flickering. "Is this typical/expected behaviour?" - no, there's definitely something corrupting the da...

Hello, Thank you for posting on the forum. It sounds like your connection to the EVE is degraded. Power may also be a factor. Can you please re-try with 5V supplied on the barrel jack (of the USB bridge). Also, if you have another FFC cable you can use, please try. The FFC cable contacts can easily ...

Hello Cecil, Do you only need to put "Text" at the upper right corner of the display as your start up screen? Try this: 254 64 32 32 32 32 32 32 32 32 32 32 32 32 32 32 32 32 T e x t 32 32 32 32 32 32 32 32 32 32 32 32 32 32 32 32 32 32 32 32 // 20x spaces 32 32 32 32 32 32 32 32 32 32 32 ...

Hello Jean,

Thank you for the scope captures.
As I write this reply, I see that you have figured out the issue and the display is now working.

Hello Jean, Thank you for posting on the forum. I also received your email via support@matrixorbital.ca, I hope you have read my response. With the big 7.0" display, you will need to make sure to supply external power (5V-15) via the barrel jack on the USB bridge. Let me know how it turns out. ...

Hello Cecil,

Thank you for posting on the forum.

You should be able to power the display via the Communication/Power header (header 1 on Table 1 of the manual); and communicate via the DB9. As per custom characters, there is a good example on section 3.1 in the manual.

Hope this helps.
