Hi,
I have a control unit that consists of a Cortex M4F, few LEDs, buttons, flash storage and LiPo battery. I also have a PCB with an accelerometer. For now, they are connected with wires and communicating through SPI. When I recharge the device (now it has micro USB for that), the sensor board may not be connected as I don't read it then. Also, during the recharging time, the data from flash (stored while running) is transferred to PC. My question is, how can I add USB Type-C to my control unit and sensor board in order to be able to communicate with the accelerometer using USB Type-C and using the same port to recharge the battery and transfer data that has been stored in the flash? I have to mention that the voltage from sensor board is 1.8V.
Regards,
Gabriel

Hi Gabriel,
Could you show us a block diagram as an eaxmple that what you want to do?
If so, we can figure out good way to you.
Since Type-C connector/receptacle does not have SPI line, you need to use USB Serial such as CY7C65211.
like this: SPI <-> [USB Serial converting from SPI to USB] <-> Type-C
Also, VBUS on Type-C has to provide at least 5V. Would it be a problem on your control unit?
For your information, videos might be helpful to you imagine the big picture (See [Videos] tab)

This is an image with the two states of the system. I just realized that the USB may be microUSB as well, I don't need USB-C.
