IWR1443BOOST: Connect IWR1443BOOST to CC1350

Part Number: IWR1443BOOST
Other Parts Discussed in Thread: CC1350, UNIFLASH

Hello,

I am planning to make a sensor network that using CC1350 as the radio. I want to transmit data from IWR1443BOOST EVK. Do I still need to connect R102 in order to be establish connection between two boards. Moreover, beside using R0 resistor, can I make the connection between two pins using solder, would it cause any problem?

Thanks,

Alex

    Hello,

    Depending on your approach, you need to consider the control, data export, flashing for updates, power control, and aux functions. 

    In some cases the control port is Control UART (OOB Demo), or SPI ( TIDEP0091).  The Control UART, RS232Tx, RS232Rx, and MSS Data Logger UART Tx are used for the Out of Box Demo communication.

    The SPI interface is SPI_MISO, SPI_MOSI, SPI_CLK, SPI_CS, Host_Interrupt (Radar output) - these signals are for the Communication of commands, and if programmed data over SPI.   Note: SPI is a slave in the TIDEP0091 code.

    There are specific pins for Uniflash or flashing QSPI, Control UART, nRST, SOP2.  

    For level Sensing new release of code, you will need GPIO-1 as the Calibrate =1, Measure = 0 control.

    PMIC_EN, PGOOD, AR_MCU_nRST are needed if you wish to power off the Radar sensor between measurements

    The booster pack BP/LP connections for these signals are shown on the EVM schematic, along with needed resistors

    Sheet 10 of the schematic shows the BP/LP Connectors.

    The XDS110 - USB for the mmwave sensor normally controls the RS232Tx, RS232Rx, and also receives the MSS Logger Tx UART.

    The XDS110 - USB also has an nRST signal, and the JTAG signals, TMS, TDI, TDO, TCK.

    If the CC1350 is the master processor, and you are not using the XDS110 on the mmwave sensor board..

    AR_RS232Tx, install R169, J6-5, remove R128

    AR_RS232Rx, install R166, J6-7, remove R129

    AR_MSS_LOGGER, install R26, J5-9, remove R136

    AR_NRST_XDS,      ,    , remove R80

    AR_TMS, install res to GND - R69 side,    , remove R69 - TMS = '0'

    The power signals, for power switching, power supervisory, and external nRST control

    PMIC_EN, install R102, J6-16, 3.3v open collector drive '0' for OFF

    PGOOD, R107, J6-14, suggest mod EVM for power supervisory - remove R141, add wire R143 to R138 open collector

    AR_nRST_MCU, R2, J5-10, low for reset

    SOP Controls - SOP0 = 1 for operation, SOP0,2 = 1 for flashing QSPI

    MCU_SOP0, R36, J5-19, always '1'

    MCU_SOP2, R36, J5-15, operational = 0; flashing = 1

    SPI connections

    AR_SPICLK1, R76, J6-13,

    AR_CS1, R1, J5-6, 

    AR_MOSI1, R4, J5-12

    AR_MISO1, R6, J5-14

    AR_HOSTINTR1, R10, J5-16

    GPIO-0, install R164, J6-15, timing strobe from mmwave sensor

    GPIO-1, install R9, J5-8, input for TIDEP0091, '1' calibrate, 0 measure

    Joe,

    Thank you for your guidance. I will let you know if it works!
