Hi Team,

I need your support on the following request:

#####################################

Is it possible to use the CC2340R52E0RKP wireless-MCU to manage the control of two 12V DC motors (using the DRV8231ADSGR chip) and simultaneously manage the wireless stack using a single Cortex M0 (the chip does not have a core dedicated to the RF section)?

In our application, the two boards must continuously exchange status information and the RX board, at the same time, must move two DC motors, controlling their position using a position sensor.

Regards,

Fabio

Hi Fabio,

Thank you for reaching out.

The CC2340R has well suited timers for motor control (cf. §10.4.4 - 10.4.7 of the CC23xx SimpleLink Wireless MCU Technical Reference Manual) leading to limited overhead on the Bluetooth communication.
In addition, even if there is no per say a radio core on this device, there are several hardware accelerator (packet engine, whitening, CRC) limiting the usage of the core.

At this point, I am not concerned by the processing power offered by the CC2340R device vs what is required for your use case. I am rather unsure the number of timers available on the device will be sufficient for driving two motors independently. Please use the reference I have shared to get this check for your use case.

I hope this will help,
