Other Parts Discussed in Thread: CC2640

Hi

I'm wondering can cc2640 provide in 2 uart port?

If can, does SPI can also exist?

Can give me some example to do this.

Thanks

    Hi,

    The CC2640 has only 1 physical UART in the CC2640 device.

    However, there is the Sensor Controller which can bit-bang the bits to communicate like a UART module.
    If you do use the Sensor Controller, then you must be aware that the Sensor Controller will be dedicated to the UART and nothing else.

    As for the SPI, there are 2 SPI modules, so it should not be a problem. But it will also depend on what IOs are left on your device. The 4X4 has only 10 GPIOs.

    I do not have any examples to provide, but you can look through the BLE stack for examples or the forums for more information.
