Re: Using EVE2 display with Mbed OS

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:

Re: EVE intermittent display corruption

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...

Re: EVE intermittent display corruption

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 ...

Re: C++ using customer characters? OK204-25-USB

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 ...

Re: EVE2 USB2SPI kit problem with EVE3-70G-BLM-TPC-F32 display

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. ...

Re: LK204-25 Startup Screen

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.

Re: Using EVE2-70A-TPN with STM32 NUCLEO-F446ZE

Hello Tuomas, Sorry to hear about the connection mishap. When you connected the display using the wrong FFC cable (contacts on same side), I imagine R1 and R2 on the EVE2 are populated? If that is the case, then yes 3.3V rail is shorted on the source and on the EVE display - and sounded like your bo...

Re: Using EVE2-70A-TPN with STM32 NUCLEO-F446ZE

Hello Tuomas,

Thank you for posting on the forum.

I apologize for the error on EVE library. It is now fixed.
CMD_NUMBER used by Cmd_Number() was incorrectly defined:
#define CMD_NUMBER 0xFFFFFF38 was changed to:
#define CMD_NUMBER 0xFFFFFF2E

Thank you,

Re: image conversion of PNG file

Hello Steve,

Thank you for posting on the forum.
The array of data in the png and jpg demos are bin to hex conversions only of the images.
There are no format conversions. Please try again and get back to us if there is an issue.
