Part Number: MSP430F2011 We have a headset, the basic situation is as follows: 1. There will be one MCU on the left and the right (both powered by 3.3v). 2. Communication between two MCU will use UART 3. The UART wire passes through the headset wire (as shown in the figure below and the use of the wire around the headset wire). We are worried about the influence of transmission rate or other interference after the UART line passes through the headset (the length of the headset is about 650mm), please help to evaluate: 1. From your experience in using TI MCU, does it make any difference?If not, why not? 2. If there is any influence, do I need to add a driver BUFFER?If yes, could you please recommend a two-way bus buffer suitable for UART communication? 3. Does UART transmission line need to be protected by a separate shielding line?
