Discussion - EVE / Re: EVE Asset Builder Installation Problem
« on: March 24, 2020, 01:00:46 PM »
Hello,

I tried at my side on a clean PC but could not replicate the same problem.
We can use EAB to convert the font successfully.

EAB 1.2 is using python 3.6.5 to generate the executable. Can you try installing Python 3.6.5?
Also can provide the screenshot of the error message when you run the font converter on EAB.

Hello,

Thanks for giving this a try, I have passed your query on to the development team.
Hopefully they should be able to provide a resolution.

Hello,

Can you try uninstalling and reinstalling EAB with admin privileges?

I believe that EAB should install Python during its own installation process, but if the error persists you can download Python from the following:

Discussion - MCU / Re: FT90x Camera Overwrite read data test pattern
« on: March 18, 2020, 04:31:38 PM »
Hello,

If the changes are in the cam_isr function then the dummy code will have to stream the required data at the same rate as that coming from the camera interface. This will mean that the dummy image will have to match the size and format of the camera output. The advantage of doing this is that the timing strobe from the camera interface will be present and ensure that data is sent at the exact correct rate as expected by the host. The disadvantage is that the data size and format must match the output of the camera exactly.

An alternative would be to make another function inject data into a buffer that the USB portion will read. This will have to be done by a timer to make sure that it is synchronised with the data rate and frame rate that the host expects. Not easy to do.

So, to summarise, the data rate (and hence the frame rate) and the data format need to match what the host expects. A USB analyser would be the absolute minimum required hardware to make this work. Even with that it might be difficult to make it match with software alone.

Hello Simon,

We discovered an issue with EAB regarding 4-byte UTF-8 characters.
EAB v1.4 is scheduled at Mar 25 and will include a fix for this.

Hello,

I had passed this on to the development team to have look at but I haven't had a reply yet.
I will chase them up for you.

Hello Simon,

I will pass this on to the R&D team for clarification on UTF-8 encoding support.

Hello,

We have two screen prototyping development tools available, the first is called EVE Screen Designer (ESD). ESD can be used to develop an HMI using visual programming techniques, and can export code to our FT9XX series of MCUs:
https://brtchip.com/esd-4-8/

The second is called EVE Screen Editor (ESE), ESE can be used to design screens and their layouts, but it does not produce logical code for the given screen. This gives you access to the raw display list for a given screen which can be easily transferred into which ever library you are using:
https://brtchip.com/eve-screen-editor/

Hello,

A good place to start would be our main 'Sample App' this covers a wide variety of examples including text entry for your HMI:

« on: February 28, 2020, 10:02:04 AM »
Hello,

You can clear the screen background to white by setting the CLEAR_COLOR_RGB to 255,255,255 as shown below.

CLEAR_COLOR_RGB(255, 255, 255)
CLEAR(1, 1, 1)

Hello,

If it is an MJPEG compressed output from the camera then you would need to form a JPEG image.
You could make a JPEG test card image, store it in Flash or RAM, and send that into the stream.

If it is uncompressed output from the camera, then the format is a variant of uncompressed data stream called YUY2.
You just need to calculate the chrominance of each colour required at points on the display and send them as required.

Hello,

The complete source code is provided allowing you to customise however you require. It can be found at the following location after installing the FT9xx Toolchain:

Test and Review Area / Re: BRT_AN_025 Beta - Portable MCU library for EVE
« on: February 25, 2020, 11:12:44 AM »
Hi Rudolph,

Thanks,
It is good to get your thoughts on the code and we'll certainly go through and review your concerns and recommendations.

Just to provide a few initial replies,

This library does use SPI burst writes and so the address is only sent once and the commands are then streamed over SPI and so it works in a similar way to your library.

The STM32 one was built using the Keil uVision IDE.

We thought our functions here...
EVE_LIB_BeginCoProList(); // CS low and send address
commands
EVE_LIB_EndCoProList(); // CS high and update REG_CMD_WRITE
EVE_LIB_AwaitCoProEmpty();     // Wait pointers becoming equal

... were quite similar to your functions here...
EVE_start_cmd_burst(); EVE_end_cmd_burst(); EVE_cmd_start(); 

We may have some duplication however. There could be cases where this is needed (e.g. if you execute a command and then want to perform other register or memory actions when complete rather than send a new co-pro list) and so we do check for the completion of the commands at the end of the list as well as at the start. We may be able to optimise this however to make it run faster.

We are keen to make the code as good and as easy to use as possible and so we appreciate your honest feedback,

Best Regards, BRT Community

Hello,

The logic analyser captures would be useful if you could provide these.
Do they include the CS# line?

Hello,

Can you let me know what your initialization sequence is and at which point you are setting the REG_SPI_WIDTH register?

Our main 'Sample App' at the following link can be configured to use Quad SPI via the 'platform.h' file, it supports our USB to SPI solutions (FT42222 or MPSSE) and our FT9xx series of MCUs:
