RS-422 adapter problem [solved]

[Mikael Gustavsson]

You could try to add a delay after enabling tx.

Replace the code:

Code:

Send:    ; Enable tx
        .ifdef USE_TXENABLE
            bset    LATR_TXE, #LATB_TXE
            nop
        .endif

With, try with different values.

Code:

Send:    ; Enable tx
        .ifdef USE_TXENABLE
            bset    LATR_TXE, #LATB_TXE
            mov 128,WTEMP2
            dloop: dec WTEMP2,WTEMP2
            cp0 W6
            bra NZ,dloop
        .endif
