Thansk Andy for your support, i'm going to explain better the problem.
This is the code: // definition #define Sfr(x, y) sfr x = y Sfr (SBUF , 0x99); #define SetUARTMode1 SCON = 0x50; /* uart in mode 1 (8 bit), REN=1 */ #define Set9600BaudT1 {TH1 = 0xFA; TL1 = 0xFA;} /* 9600 Bds at 22.118MHz */ // enable interrupt.... //// in my interrupt serial routine lastCharOnRx = SBUF; With my emulator (Phyton PICE 51) i break on this last line. If from the pc I send byte from 0x00 to 0x79, on my breakpoint i see the correct byte sended. If i send, from the pc, for example 0x80, on my emulator i see 0x00. If i send C2, i see B4.... I tried to typedef sfr as a unsigned char What made you think that this would help? I don't know if it is the right think... :( What is RC51? It Is compiler distributed in the Raisonance kit. Thanks |

| uhmmmm | 01/01/70 00:00 | |
| unsigned is the default type for char | 01/01/70 00:00 | |
