Discussion - EVE / Re: UTF-8 Encoding Error
« on: April 29, 2020, 11:58:02 AM »
Hello

I have asked the development team if the font convertor version number should have incremented for the latest release.

In the meantime, we have given it a go here, please see below for the ESE source and attached screenshot:

Discussion - EVE / Re: Using Eve Screen Designer with Riverdi EVE 3 TFT display
« on: April 28, 2020, 04:46:48 PM »
Hello,

All ESD projects created for FT90X based platform can exported as eclipse based project.
When creating the new project select the target platform as VM816C50A , the default MCU platform is MM900EV1B board. To get the eclipse Based project, you can use File > Export as Eclipse Project.

However, if you want to support ESP32 platform, you will still need adapt the code in hardware abstraction layer for the ESP32.

Discussion - MCU / Re: FT9xx Driver problem Windows 7
« on: April 28, 2020, 04:32:02 PM »
Hello,

Which hardware are you using? Is it our FT9xx Modules or your own custom hardware?

The problem seems to be with the DFU drivers.
USB DFU programming can be a good option for production or field programming but not for development. The UMFTPD2A is recommended for programming and debugging.
The FT9xx modules and ICs in stock may be programmed with an old version of the bootloader so the DFU driver is not loaded automatically. An unknown device is shown in device manager. The FT9xx Programming Utility is also unable to see this device.
The latest DFU driver is now a WinUSB driver and should be installed automatically via Windows update.
Note that this is a USB DFU class device so can't be included in CDM v2.12.28 WHQL Certified as this driver is for our vendor class devices.
The FT9xx Programming Utility can be used to 'Restore Bootloader' to this latest DFU version but this requires the UMFTPD2A.

Please use the UMFTPD2A to ‘Restore Bootloder’ on the FT930 using the FT9xx Programming Utility:



If you have any other problems, please send us an email to your local support team:

Hello,

Just to clarify, after using the latest version of EAB, your special symbols are still not showing on screen when you attempt to use them in your code?

Discussion - MCU / Re: RTC on FT90x revision C
« on: April 21, 2020, 04:37:23 PM »
Hello,

Yes VBAT of the FT90x works in the same way as FT93x.
VBAT is only the RTC power source.

The RTC in FT90x Revision B was a simple counter. It provides information as a basic “system on” timer. The RTC in FT90x Revision C has been redesigned to provide more detailed information. It is powered by an external battery source.

See the following notes:

PCN BRT 005   
BRT AN 019 Migration Guide Moving from FT90x Revision B to FT90x Revision C

Please contact us via email regarding the RTC design and we can contact R&D to see if they have any more additional information that can be shared.

Best Regards,
BRT Community

« on: April 14, 2020, 04:31:12 PM »
Hello,

VBAT is the +1.5V RTC supply voltage. An external battery should be connected to the VBAT pin.

There is no application note or characteristics available.

The MM900EV1B schematics show an example of the connection required:



Also the RTC needs to be calibrated for an accurate time. See the following documents:

BRT_AN_004 FT93X RTC External Power Switch Circuit
BRT_AN_009 RTC Calibration in FT93X

Hello,

As far as I am aware the development team have been able to reproduce this issue and are currently looking into a fix. Hopefully this will be rolled into the upcoming EAB 1.4 release.

Discussion - EVE / Re: max resolution for video playback
« on: April 09, 2020, 03:16:51 PM »
Hello,

It is possible to store any graphics asset data on an external Flash IC and stream it to the BT81x. However you would still need the host MCU to issue commands to EVE for the retrieval and display of this data.

Discussion - EVE / Re: max resolution for video playback
« on: April 09, 2020, 02:07:05 PM »
Hello,

The EVE series is certainly capable of playing video at such resolutions, our main SampleAPP includes an example of playing a 800*456 avi video. But it is important to take into account that EVE is not optimised for video playback, and is intended to be used for HMI solutions such as control panels, etc. As such when streaming video you must ensure that the BT81x is fed with data continuously over the SPI connection from your host MCU. Implementing a Quad SPI interface would be beneficial in such a scenario, as EVE essentially draws each frame as the data is received from the host MCU, and this means if there's a pause in the data stream the video will pause on the EVE screen.

Hello,

The 300ms delay on start-up is considered as a safety timer to guarantee the chip internal boot-up sequence has completed.

Discussion - EVE / Re: Using Widgets of Screen Designer in own code
« on: April 08, 2020, 03:49:31 PM »
Hello,

The dev team replied and ESD provides all the source code of ESD widget.  You can find it at widget folder $(InstallationPath)\Libraries\Ft_Eve_Widgets. 
However, some advanced ESD widgets are based on other base widgets. In this case, Esd Archslider is the advanced widget.
Esd Arcslider widget is constructed on top of other widgets: Esd Partial Ring.  Esd Partial Ring is based on Esd ArcLine widget.

An Esd Arcslider widget uses 3 Esd ArcLine widgets. Therefore, to check how to draw the Esd Arcslider, you need study how to draw the arcline.

I attached the Ft_Esd_Arcline.c for your reference. You also can find it at the  widget folder above.

Here is the display list to draw the Esd Arcline . Users can find this from Inspector window which is near to Error List.
