Compiler/PGA460PSM-EVM: PGA460PSM-EVM with URAT only!

Part Number: PGA460PSM-EVM
Other Parts Discussed in Thread: ENERGIA, PGA460, MSP-EXP430F5529LP

Tool/software: TI C/C++ Compiler

Hi,

I would like to use the PGA460PSM-EVM module to get the distance to the microcontroller (BeagleBoneBlack). I have some questions:

1. Is it possible to use (out of the box) PGA460PSM_EVM with only a microcontroller if only need URAT connection?

2. If so, What pins from the library I need to change?

3. Can I connect TX/RX pins to any TX/RX pin if my controller has multiple URAT RX/TX pins?

4. if so, where do I have to define which RX/TX pin I am using? I found and try to edit Energia Library for my controller, but I don't know where to specify TX/RX URAT pins.

5. Is there an alternative way to get distance without using the Energia Library? A library for BeagleBoneBlack?

	#define DECPL_A 2
	#define RXD_LP 3
	#define TXD_LP 4
	#define DECPL_D 5
	#define TEST_A 6
	#define TCI_CLK 7
	#define TEST_D 8
	#define MEM_SOMI 9
	#define MEM_SIMO 10
	#define TCI_RX 14
	#define TCI_TX 15
	#define COM_SEL 17
	#define COM_PD 18
	#define SPI_CS 33
	#define SCLK_CLK 34
	#define MEM_HOLD 36
	#define MEM_CS 37
	#define DS1_LED 38
	#define F_DIAG_LED 39
	#define V_DIAG_LED 40

Thank you,

D

    Hi Dharmin,

    Answering your questions:

    Yes, it is possible to use the PGA460PSM-EVM as-is out of the box in UART communication mode. The UART pins are mapped as PGA460-TXD-Pin10 (TXD on the EVM) to "RXD_LP" and PGA460-RXD-Pin11 (RXD on the EVM)  to "TXD_LP" of the Energia library. You can also use SPI as an alternative communication mode (requires connection of the additional SCLK pin on the EVM; there is no chip-select on the PGA460).

    If you have the MSP-EXP430F5529LP, you can jumper wire the UART pins of the PGA460EVM-PSM to use the GUI for a better visualization and optimization of the time of flight results. Other than the Energia library, there is no other library available for the PGA460.
