#24271 - voice-uni_dir |
how can we use "port-2" in 89C51 r 52 as an very fast half duplex mode voice transmission which is at rate of 8KHz.
voice is packetized as SOURCE_ADDRS+DESTINATION_ADDRS+8-BIT VOICE DATA AT 8KHZ+FF(as stop byte). the bus is not able to switch between two microcontrollers . TP3054 is used on the input side. help me out. |
