Hello.

I am testing with CY8CKIT-062-WIFI-BT.

Threre is an emWIN_TFT_FreeRTOS example, but the bitmap image is displayed slowly.

I'm not sure if it's the effect of RTOS, but is there an example that the bitmap image is output quickly?

Hi @YSJE_3566666 ,

The reason you are facing the slow display of  bitmap image could be because ModusToolbox project uses a bit bang method to drive the TFT, which is a much slower method as compared to the PSoC Creator project, which uses a driver implemented in UDBs (our programmable digital blocks).  Currently, we don't support UDBs with ModusToolbox. 

Hope this helps you clarify!

Best Regards,

Hi Aashita_Raj,

Thanks for your reply.

I found code example CE223726(TFT Display) for PSoc Creator which provides fast LCD output.

As you mentioned it uses UDB. But how do I use the CY8C624AAZI-S2D14?

Not only PSoC Creator 4.4 doesn't support it, but Modus Toolbox doesn't support UDB.

Thanks and Regards.

I found out that CY8C624AAZI-S2D14 doesn't have UDB.

I need 2MB flash and fast LCD output. If so, there seems to be no suitable product.

Is there a way to speed up LCD output on MCU product with 2MB flash?

Hi @YSJE_3566666 ,

PSoC Creator 4.4 does support UDB. And you can use CY8C624AAZI-S2D14 device to run your the code example by following-

1. After opening the code example in PSoC Creator, right click on the project.

2. Go to device selector.

3. Select CY8C624AAZI-S2D14 device from the list.

4. Click OK.

Please let me know if this helps or in case of any further query.

Best Regards,

Aashita

Hi Aashita_Raj,

I meant that PSoC Creator doesn't support CY8C624AAZI-S2D14.

I couldn't find CY8C624AAZI-S2D14 in device list.

Thanks and Regards.
