  • TMS320F28022: SCI TX output timing

    TI Thinks Resolved
    Part Number: TMS320F28022 Hello, It is described in 【1.1.7.2 Transmitter Signals in Communication Modes】 on page 18 of sprugh1c as follows. Notes: 1. Bit TXENA (SCICTL1, bit 1) goes high, enabling the transmitter to send data. 2. SCITXBUF is written…

  • TMS320F28022: About SCI SWRESET

    TI Thinks Resolved
    Part Number: TMS320F28022 Hello, Please tell me about the timing of the sending and receiving data with a SCI SWRESET. SciaRegs.SCICTL1.bit.SWRESET = 0; SciaRegs.SCICTL1.bit.SWRESET = 1; . . Set SWRESET to "1" when sending and receiving is possible…

  • TMS320F28022: Transmit only for use with C2000/AFE031 App Note, replaces TMS320F28379

    TI Thinks Resolved
    Part Number: TMS320F28022 Hello, We are porting the transmit-only software example for this app note ( http://www.ti.com/lit/an/sprac94b/sprac94b.pdf This uses 2 HRPWM outputs on GPIO0 and GPIO2. We've gotten pretty close but the HRPWM output is…

  • TMS320F28022: SCI start bit detection timing

    Answer Suggested
    Part Number: TMS320F28022 Hello, Please tell me about SCI SWRESET. When initializing with SWRESET (active low), when SWRESET = 0 is set to 1 and enabled again, at what timing is the start bit detection of the received data started? Below, is understanding…

  • RE: CCS/TMS320F28022: Guaranteeing order of FLASH load sections

    Resolved
    I solved the problem a different way. Rather then create 5 separate segments and let the linker do with them what it likes, I concat the 5 segments into a single segment, and keep track of the starting positions of the 5 parts. The linker now behaves…
