TM4C129XNCZAD: TM4C129XNCZAD

Part Number: TM4C129XNCZAD
Other Parts Discussed in Thread: CC3120MOD

I am trying to design an equipment with the TM4C129XNCZAD uC with the following options. I am new to TI TM4C129 series, though I have used TM4C123 kit in CCS.

  1. Ethernet, 4xSPI, 6 x UARTs (2 with CTS/RTS and rest with simple Rx/Tx & 1 with RS485), 4xI2Cs, USB (OTG/HOST - Host Preferred), 42 IOs with Interrupt facility
  2. LCD Port for 3"+/5"/7" (For various applications)
  3. SPI Ports to drive CC3120MOD, 16MBit memory, SD card Interface and One for future use
  4. In case I use SPI for driving an LCD, will the Graphic library work for this display too? or The Graphic Display Library is not useful for SPI TFT Display?

When I used PinMux uitility, it generated 24 Pins for Ethernet, but I saw only 4 wires for Signal and 3 Pins for LED. So is the case with USB. Also I want to use UART0 and UART1 as simple UART with only RTS/CTS, but it allocated all 8-bits to it.

How to tell the Pin Mux That extra signals need not be generated? Or do the extra signals give any benefit in my design?

Or Am I using a wrong type of TM4C129? If so, please suggest a proper one with the above stated requirements. I have got TM4C129EVK with me for trials. I have selected the device TM4C129XNCZADI3 as I felt this is the TOP of the heap and hence will have all the facilities. Later the Firmware/Software team will write their firmware.

    Hi,

     First of all, did you get any warnings or errors when you use the PinMux utility. It can generate errors if it detects any pin conflicts. I don't understand why you mean that there are 4 wires. Which 4 wires?

      The graphic library is used for the LCD interface. I don't think you can use the graphic library as is for a SPI based display.

    If you don't want to use the CTS/RTS for UART0/UART0 then you just unselect the unneeded pins like below.
