#75505 - RE: Memory mapped I/O hassle Responding to: ???'s previous message |
Hello Rob,
It would appear Mr. Anders Sandström is correct in his statement. I took Raghunathan example program and compiled it with asem.exe It failed with the 10HPMOTOR: DBIT 1 line. I changed the line to MOTOR10Hp: DBIT 1 and it compiled successfully. See below for samples. Regards, Charles Bannister
