i am going to do a 8052 based project in which we must be interface two s-series 8052 with each other but we have no idea about it. can anybody help me to suggest me how to interface two 8052 together.
you still have not answered
distance between the two amount of data - how much, how often environment (industrial, home, office ....) required speed SPECIFIC chip type (ALL the letters and numbers) production volume (weighing between cost and ease of development) are you locked in your chip selection or can you use better alternatives
yes, UARTs can be used, but are not necessarily the optimum solution, what is depends on the answers to the above.
