Hi it's me again with my strange question.
Here is the question.
i have pic 16F877 connected to 2 x 16F628 and 2 x (16x2) LCD and a keyboard
i want to use pic 16F877 as master controller connected with PC (1. connection) and try to use another LCD controlled by 16F628 again connected with 16F877 (2. connection) and the last connection again connected with 16F628 (3. connection)
in the picture u can see the shema of the question.
How can i use HSERIN and HSEROUT commands to control them?Is there any solution to control them.If any body could give me an example i will really be glad.Thanks for reading my strange question.
