Discussion - Software / Re: USB Keyboard Host on VNCII
« on: April 01, 2020, 04:47:50 PM »
Hello,

There are plenty of examples available with the IDE.

Take a look at V2DAP:

C:\Users\Username\Documents\FTDI\Firmware\Samples\V2.0.2-SP2\VNC1L\V2DAP

This would allow a BOMs class device on Port 2 and HID class device on Port1.
You could customise the firmware to meet your needs or create your own custom firmware.

Also refer to the following documents:

Vinculum Firmware User Manual
AN_176 - Vinculum Comparison of VDAP and V2DAP

There may be other users on the forum who could help you further.

Discussion - Software / Re: FT905 I2C Slave Example
« on: April 01, 2020, 04:47:12 PM »
Hello,

Hopefully someone on the community forum has experience with the Aardvark Adapter.

You can refer to our documentation for further information:

AN_365 FT9xx API Programmers Manual
BRT_AN_020 FT90X Revision C User Manual

You must call spi_enable_interrupt in order to use interrupts with SPI.

Discussion - Software / Re: FT813 - Fonts bigger than 39 not working
« on: March 31, 2020, 12:51:29 PM »
Hello,

Unfortunately I did not have a chance to before the UK (where I am based) went into lockdown due to the COVID-19 pandemic.
As such I cannot get into the office to acquire the correct EVE board to try this on.

Can you try taking logic captures of the SPI lines? you can decode these and see if the correct data is getting sent to the EVE IC for the second larger font example.

BRT Community

Hi,

could you reproduce the error? Any news regarding this issue?

Thanks,
Santiago

Hello,

The SPI slave example in AN_360 is designed to work with the SPI master examples also in AN_360.

Check the 'Aardvark I2C/SPI Host Adapter' SPI master settings and either modify the example code or create your own custom code to communicate with this device.

Hello,

Please see the following application note which covers UVC master bus data transfer to an FT602:

Hello,

The FT602 is designed to transfer uncompressed YUV422 video data. All of our FT602 resources including software examples can be found on the product page:

Hello,

Please see AN_428 D2XX EEPROM Programming Examples for some useful information.

Also refer to the D2XX Programmer's Guide.

FT_EEPROM_Read and FT_EEPROM_Program must be used with the FT_X Series.

If you send us an email I can send a simple code example. This forum is limited to 20000 characters so couldn't post it here.

Hello Mike,

I don’t think this is something that’s ever been tried before.

Have you tried removing duplicate definitions if they are the same function?

Otherwise you may have to control these separately with two different programs.

Maybe some other users in the community can help you.

Discussion - Software / Re: C232HM under virtualbox
« on: March 17, 2020, 04:35:13 PM »
Hello,

We cannot support any virtual type system. There can be all sorts of problems that are out of our control.

You can find our supported drivers here:

http://www.ftdichip.com/FTDrivers.htm

If your target OS is Windows or Linux, please use it directly on that OS without any virtual machine.

Error 4 is FT_IO_ERROR.
Error 18 is FT_OTHER_ERROR.

Hello,

Thanks for providing these, I will have a look at recreating your issue with the font files your previously provided. This should help me pinpoint where the problem is.

Discussion - Drivers / Re: FT_GetQueueStatus() does not return a DWORD
« on: March 13, 2020, 02:47:20 PM »
Hello,

It is also best to have your application regularly checking the queue status and reading the data from the driver buffer into your own application buffer for processing.

If the driver buffers keep filling up, you will eventually reach a point where either data is lost (if you don't use handshaking lines)     or where the chip is unable to take more data from the attached serial device and de-asserts the flow control (if you use handshaking which we strongly recommend). This would be CTS or DSR for UART and would be TxE for FIFO. In this latter case your serial/FIFO device would need to pause sending and buffer up any data.

We therefore recommend to have your application check the queue status, read however many bytes are reported available if > 0 and then repeat this etc.

Best Regards, FTDI Community

Hello,

By any chance are you loading both fonts into RAM_G concurrently?
I cant see any glaring issues with your code, looks like you've set everything correctly for the 'not working' font data.

Hello,

Section 6 of the following has an example of using customer fonts:
FT81X Simple PIC Library Examples

Can you show me the section of code where you assign the bitmap properties to your custom font?
