Hi team:

I want to read 8-bit data from a peripheral device through data bus D0...D7,

can I configure CYW20719 pins to be a 8-bit data bus?

Thanks

Please note,

We do not support parallel bus data traffic in our chips.

Unless there is an addition HW support, we cannot perform parallel read just based on the firmware.

Hi Jian,

You want to receive data serially or over Bluetooth? You can use SPP demo app available in WICED Studio to receive data over Bluetooth. CYW20719 also supports I2C, SPI interface.

Please provide more details about your application.

Hi,

I have peripheral device that has a 8-bit parallel data bus( D0...D7 ), and send these data by Bluetooth.

Can I configure CYW20719 pins to be a 8-bit data bus?

Does CYW20719 supports paralles bus by GPIO?

Thanks

Hi JiZh_4619191

Sure you can use GPIOs. There is no parallel/port read option. You may have to do coding in your application to read it 8bit data from 8 different pins. Please see the available GPIO APIs below.
