Hello,

i am trying to interface the TFT with my development board using SPI drivers. Please provide me some SPI examples or TFT interfaced code examples.

Thank You AnjanaM_61​@

Hi

You can refer to these examples. They are based on the CYW20819 device but should work for CYW89820 as well.

Please try it and let us know if you need any help.

thanks for the reply, i will look into those examples and will share the results. although i have some doubts ,

1.can i interface external flash memory using SPI and perform read and write operations from flash?

2.can i run DUAL SPI and BLUETOOTH operations  at the same time?

3. does cyw989820evb-01 has dual cores? one core for bluetooth and one core for spi ?AnjanaM_61​

Hi daba_4649501 ,

1. Yes, you  should be able to  write to flash and read from flash.

2. Yes You can have Dual SPI and Bluetooth operations at the same time.

3. All our current chips are single core. Cortex M4. It is time-shared between peripherals and Bluetooth. The user do not have to worry about it. It is handled by the ThreadX RTOS.

Anjana
