#104243 - bitbang Rx of first byte Responding to: ???'s previous message |

am using phillips 89c51rd+ controller, Why? Isn't it obsolete by now? Additional questions: Is you hardware design already determined, or can you move/short some pins around? (it is easier to make a bit-banged-UART-receiver if the startbit edge can trigger an interrupt). Venkatesh Pandit said:
first and last byte is a check for the correct data... Does this mean that the first byte is a predetermined value? If so, you can/should/must bit-bang receive the first byte, then set the baudrate for UART accordingly. Look at the Atmel site, there is a nice appnote of a timer-interrupt-driven multiple-sample-per-bit bit-banged UART (probably of Matra/MHS-Temic heritage), get inspired. Jan Waclawek |
