TMS570LS0714: LIN as GIO

Other Parts Discussed in Thread: HALCOGEN

Hello, I want to use LIN pins as GIO but I ma not sure about the register I have to use as GI.
I think I shoud use thi function:

RD6= gioGetBit(linPORT, PIN_LIN_TX);
RD5= gioGetBit(linPORT, PIN_LIN_RX);

Is that correct? Am I taking the velue of the TX and RX LIN pins?

    I have to set 8 bit in a byte, but with the function gioGetBit I have the error #41 expected an identifier. In addition linPORT is undefined. 

    uint32 RD7=gioGetBit(gioPORTB,1); //get the current value of BIOB[1]. Pin 133 uC.
    uint32 RD6= gioGetBit(linPORT, 1);
    uint32 RD5= gioGetBit(linPORT, 2);
    uint32 RD4= gioGetBit(mibspiPORT1,1); //get the current value of MIBSPI1NCS[0]. Pin 130 uC.
    uint32 RD3=canREG2->RIOC &1U; //get the current value of the RX pin of that CAN port (2). Pin 129 uC
    uint32 RD2=canREG2->TIOC &1U; //get the current value of the TX pin of that CAN port (2). Pin 128 uC
    uint32 RD1= gioGetBit(hetPORT1,3); //get the current value of N2HET1[30]. Pin 127 uC.
    int8_t DATA = RD1 | (RD2 << 1) | (RD3 << 2) | (RD4 << 3) | (RD5 << 4) | (RD6 << 5) | (RD7 << 6);

    Firstly, in HalCoGen configure Lin tab:
    LIN Port -> change TX Pin Mode and Rx Pin Mode to GPIO. On the same Tab you can change direction you want (input/output).

    Include reg_gio.h in your sourc file. Thre you will find macro for TX and RX pins (eg. PIO2, ...).

    You can use GIO APIs (gioGetBit(linPORT, 1) etc). As Michal mentioned, you have to configure LINTX and LINRX as GIO pins first.
