#161143 - 8051/2 serial port as shift register |
Hi all I am reasonably new to the 8051/2 I want to know if anyone has come across a piece of code where the person has used the serial port as an 8 bit shift register and used this command
MOV SBUF,SBUF it does not make sense to me at all I have done a lot of searching but maybe looking in the wrong places? I don't understand what this would do I know you could hold the data in the buffer ect but can anyone else please tell me why you would do that and for what application, does anyone know of any good code that I can look at that uses the serial port as a shift register I can find plently of code on UART etc but nothing on using the serial port as a shift register ?? if you use that command how can you get any data into the RAM ?? Many thanks Mikee |

| Read the datasheet and look for Mode 0 | 01/01/70 00:00 | |
| The datasheet for YOUR MCU - or not? | 01/01/70 00:00 | |
| it doesn't always work in the same way | 01/01/70 00:00 | |
| True; hence... | 01/01/70 00:00 | |
