Hi! I want to design a data transmission circuit (transmit 7 bits data with 1 start, stop, and parity bit) by using gates. The part I have done is CRC and parity.Now I want to design the transmission part, I want to use a counter to count the time of data division until 8 then transmit the remainder from CRC to do the parity.So where can I connect the counter to my circuit? I am using 74175(IC) to register the CRC code, 74165 to load the 7 bits of my data into the system, two 7483 for adding (process of 2 complement), one 74194(data load from 7475 if the adder output is positive value,if not the 74165 will shift data into it), and one 7475(store data of the remainder). When the 7 bits all have transmitted to the adder and the 7475 output data stopped changing, I want to transmit it to parity part.So I need one counter to count until 8( make sure the data of the remainder is in final state )Where should my counter connect? For transmission, initially I need to transmit 11 empty bits first to the receiver, how can I do it?because when my circuit clock is on, my data will load into the circuit. Thanks!
