i m using PC's parallel port to communicate with a 8052 when sending a byte to 8052 eveything is ok the byte data is sent without error but when i try to receive a byte from 8052 i.e when reading data pins of parallel port it makes very much error (i set control port bit5 to read data pins ) (cable is 5 m) (i have 74hc245 driver between PC and 8052)
my question ; has anyone experience with parallel port communication have u come up with similar results ? what can u suggest to me ?
