Discussion - Software / Re: EVE Screen Designer - Screen orientation from landscape to portrait

« on: June 14, 2018, 11:07:09 AM »

Hello,

Thanks for your question.

Unfortunately you cannot configure the tool to work with portrait mode.
However it is possible to export the code from ESD and edit the code in the FT9xx toolchain to achieve a rotated screen.

For example in the ‘SimpleLayout’ project in the ‘FT_Esd_MainLoop.c’ file I have added the 'Ft_Gpu_Co_Cmd_SetRotate()' command to rotate the screen:

Code: [Select]

ft_void_t Ft_Esd_MainLoop()
{
	Ft_Gpu_Hal_Context_t *phost = Ft_Esd_Host;

	// Initialize application
	Ft_Esd_InitDlState();
	Ft_Esd_ResetGpuState();
	Ft_Esd_ResetCoState();
	Ft_Esd_Frame = 0;
	Ft_Esd_Millis = ft_millis();
	Ft_Esd_Timer_CancelGlobal();
	Ft_Main__Start__ESD();

        //Screen rotation
        Ft_Gpu_Co_Cmd_SetRotate(phost,2);

	int idled = 0;
	while (Ft_Main__Running__ESD())
	{

Please see section 5.53 of the FT81x Programmers Guide:

Discussion - Drivers / Re: Issues with using D2XX driver without root privileges on Ubuntu (udev)

« on: June 13, 2018, 11:34:39 AM »

Hello,

Thanks for your question.

As you have discovered, elevated privileges are required to interact with the USB subsystem via a user space program. Thus requiring any software which makes use of the D2XX library to be run with these elevated privileges, this is usually achieved by running as 'root'.

I have found the following useful when writing udev rules:
http://www.reactivated.net/writing_udev_rules.html

I would suggest that if the rule works on a physical Ubuntu system, that it should work on a Virtual Machine. Although in my practical experience this is rarely the case, and VMs can be tedious to debug.

Unfortunately we have limited experience with VMs here at FTDI, hopefully one of the other forum members could point you in the right direction. Otherwise the VMware or Ubuntu forums are likely to be helpful with such an issue.

Hello,

It sounds like there may be an issue with your custom board.

Can you please send the schematics to support1@ftdichip.com and we can review them?

Discussion - Software / Re: Visual Studio Code Debugging

« on: June 12, 2018, 10:52:41 AM »

Hello,

This is quite interesting. What is the reason for creating this VSCode?

We provide a fully working FT9xx Toolchain which is supported by Bridgetek.

To help you resolve your problem, you could include the API source code in order to step into the API functions.
The source code files can be found here:

C:\Users\Username\Documents\Bridgetek\FT9xx\2.3.2\Source\src

If the source code files are not included into the project, they can not be stepped into during debug.

BRT_TN_002 Modifying FT9xx API Functions section 2.2 Copy Source shows you how to do this.

So if you include delay.c into your project, you will be able to step into this API function.

Also it could be because you have linked against the debug version of the binary (libft9xx.lib). The lib was built by our internal build system and so the debug info contains the pathname to delay.c on the build machine.

You should let gdb know that it can search your local source folder to locate the lib ft900 source code.

Hi,

Have a look at chapter 1 of the D3XX Programmers Guide which should answer some of your questions: http://www.ftdichip.com/Support/Documents/ProgramGuides/AN_379%20D3xx%20Programmers%20Guide.pdf

If you still have further questions please contact us on support1@ftdichip.com

Discussion - Software / Re: FT900 play video demo issue

« on: June 06, 2018, 11:21:15 AM »

Hello,

Yes there is a problem with this example on the website. I am waiting for it to be updated.

For now you can find the modified example at the following link, including the files that need to be placed on the SD card for this example to run:

FT_App_PlayVideo_SD_Fix.zip

FT_App_PlayVideo_SD_Files.zip

The example runs ok and the SD card can be mounted:

Code: [Select]

>(C) Copyright 2014-2015, Future Technology Devices International Ltd.
---------------------------------------------------------------------
Welcome to Video Player Example ...

---------------------------------------------------------------------
 SD Card inserted!
 Mounted successfully.

Now I would like to point to a better example here:

FT81xLiftDemoWithVideo

We do have an additional edit that does full screen but that's not available on the FTP site yet.

This example demonstrates how to use more of the video features of EVE.

Also note that EVE is not primarily optimised as a video player so there may be compromises between video size and frame rate.

Hello Rudolph,

Unfortunately Moderator approval is required for all posts due to our internal security policy.

I believe the updated Programmers Guide will be available when the IC is officially released in the upcoming months.

Thank you for pointing out the incorrect link, I will let the web team know to update this.

Discussion - Hardware / Re: FT900 PRogram interface

« on: June 04, 2018, 09:48:11 AM »

Hello,

To program and debug the FT9xx IC, you really only need the DEBUG signal but you could also connect GND and RESET.
The SPI signals and VPP FSRC are actually for programming the EFUSE, but unfortunately this is not available on the current revision of silicon. See TN_159 FT90x Errata Technical Note. This EFUSE will be replaced by OTP (One Time Programmable) memory in RevC silicon.

You can test and evaluate using our FT9xx Modules.

I would also like to make you aware of USB DFU programming which are good options for production and field programming. See a demonstration video here:

Discussion - Hardware / Re: FT232H CPU-FIFO

« on: May 31, 2018, 11:57:41 AM »

Hi,

I notice that you also sent this question to our email support channel and that you have received a reply.

For completeness below is the reply that was sent:

Sorry that the pin number 32 (ACBUS 8 ) 33 (ACBUS 9) cannot be accessed under CPU-FIFO mode. if you want to access them, you need to switch the operation mode into the CBUS bitbang mode. but I don’t think it’s what you expected.
I suggest that you select async FIFO mode for your application due to it use the same HW bus as the CPU-FIFO mode but it works more efficient.
Due to the FT232H works as the slave device under the async FIFO mode, your CPU control the data access timing and it’s not necessary to inform the FT232H that the data transfer is done.

Please continue any further discussion with the email support channel.

Hello Attila,

Could you tell us more about your planned application, for example what kind of MCU you will use and what kind of screen content you will use in your application? Each of the tools have their own advantages. You can also contact us directly at support1@ftdichip.com if you would prefer to discuss with us over email.
