Compiler/LAUNCHXL2-570LC43: TMAS570LC4357 LAUNCHPAD

LAUNCHXL2-570LC43: TMAS570LC4357 LAUNCHPAD

Part Number: LAUNCHXL2-570LC43
Other Parts Discussed in Thread: TMS570LC4357,

Sir,

I want to make my own board with two tms570lc4357 controller which will drive 4 bldc motor with incremental encoder. I have taken LAUNCHXL2-570LC43 schematic as reference. I want to have two micro usb for programming the two device. But i am wondering should I keep TMC129ENCPDT(present in the LAUNCHPAD) in my customized PCB. I found TMC129ENCPDT is a TIVA C series controller. Also i want to know the purpose of keeping this in  LAUNCHXL2-570LC43 as well as how it will serve me in my own customized PCB.

thank you

    Hello Deepak,

    You don't have to put the TM4C129x on the board. The TM4C is used as built-in XDS110 emulator. You can add a 14-pin or 20-pin JTAG header, and use an external emulator. The JTAG signals is diasy-chained for 2 TMS570 MCUs.

    If you want only 1 built-in XDS110 emulator, please add 1 TM4C129x device on the board and 1 USB header, and use diasy-chain for JTAG signals for 2 TMS570 MCUs,

    If you want to use 2 separate built-in XDS110 emualtor for 2 TMS570 devices, you need 2 TM4C129x and 2 USB ports.

    Thank you sir.

    In my custom board I need a provision of transmitting data through UART(a frame of 10 bytes in interupt mode). Should i use LIN 1 module as SCI compatiblity mode or SCI3 module.I am trying to write code using scisend() in LIN1 module as SCI compatibility mode. But unable to do it. I need 1Mbps of baudrate(precise).I found precise 1 Mbps is possible in LIN1 module. Kindly help.Thank you

    Hi Deepak,

    Either LIN1/SCI1 or SCI3 can be used. The actual baudrate can be 937.5khz. Please try different baudrates: for example 9600hz, 115200hz.
