Hello...I used this kind of connection to emulate a long cable with some disturbs, because the final machine should have the display fixed on cover of openable electric box and the electronic device fixed inside the box, with a 20-30cm cable.

Hello,

Please see our GPIO software examples provided with the library download:

.\LibFT4222-v1.4.2\samples

Unfortunately we don't have any LabVIEW examples for FT4222H.

I would recommend testing out our C programming GPIO example before continuing with LabVIEW.

Please ensure that you are using the latest LibFT4222 version (currently v1.4.2 for Windows).

If you have any further questions, you can contact us on support1@ftdichip.com.

Best Regards,
FTDI Community

Hello,

If you are using a custom hardware design, can I get you to email this into the support channel at support1@ftdichip.com ?
Please also summate the issues being experienced, any applicable code/images and any debugging you may have already carried out.

Best Regards,
FTDI Community.

The TFT which displays nothing without series resistors although set the above parameters is 4.3".
I'm using a custom design.

For 4.3" : https://drive.google.com/open?id=1bXh_Una4K4U98xN-_ZY4dj9pAg5Jo7JJ
For 7" : https://drive.google.com/open?id=1wB1WP6SLpVglopnsS2-mWtQzSnnK-w_h

I wish I had a BT815 module yet. :-)

>Finally, in the startup, BT815 is slower than FT813, the difference is around 1-1,5 second.

Seconds? That would be awfull compared to the less than 200ms of a BT813.

Hello,

Can you just clarify which of the two displays you are using is exhibiting this issue? and can you link the datasheet? Also are you using a custom hardware design or our modules?

Best Regards,

Hi,

I want to use the GPIO2 and GPIO3 simultaneously with the I2C interface in CNFMODE0.

for the configuration of the ports I have used the following procedure:

- initialization of interface A as I2C master
- suspend out deactivated
- wakeup interrupt deactivated
- initialization of interface B for usage of the GPIO

I did not get the GPIO's to work. I2C works fine.

Hi,
The result is the same, it has white pixels.
I think the display settings are correct because when a series resistor is connected to VSYNC and HSYNC pins, it displays the screens.
The settings parameters;
Code: [Select]
#define settingQVGALCDPARAMETER \
{ \
480U, /* Active width of LCD display */ \
272U, /* Active height of LCD display */      \
548U, /* Total number of clocks per line */   \
43U, /* Start of active line */    \
0U, /* Start of horizontal sync pulse */    \
41U, /* End of horizontal sync pulse */    \
292U, /* Total number of lines per screen */  \
12U, /* Start of active screen  */    \
0U, /* Start of vertical sync pulse */    \
10U, /* End of vertical sync pulse */    \
5, /* Pixel Clock */      \
0, /* Define RGB output pins */    \
1, /* Define active edge of PCLK */    \
} \

Also, I enclosed the display parameters which in the datasheet of TFT.
