BOOSTXL-CC3135: Connections

Part Number: BOOSTXL-CC3135
Other Parts Discussed in Thread: ADS1220, CC3135, CC3120, BOOSTXL-ADS1219,

Hello,

I am thinking to develop BoosterPack which works with all Launchpad. It consist from an SPI display and ADS1220. I would like to use it with MSP430G2ET, MSP430F5529LP  -that is not a problem- but would make sense to work with wireless Packs like MSP432P401R-CC3135. The problem is that the documentations of the booster connection of CC3135 is not understable: which line is free for use and which is used for communicating with processor, which is used only for programming and can be applied in normal use.

Could you help me with some reference about CC3135 and CC3120 connections??

Regards,

LAszlo

  • Hello,

    I have found BOOSTXL-ADS1219. At first glance it works with combinations of the LP-s. Is that right? Sample CCS project would be appriciated!

  • Hi Laszlo,

    Please see the section titled External Interfaces in the datasheet to better understand which signals are used with the Host MCU. Do you have any specific questions about the signals routed to the BoosterPack headers?

  • Sorry taking your time, but finally I decided to build my own testboard and with jumper-cables I can reorder pins any time they are needed.

    Anyway, I was not clear in my question: BOOSTXL-CC3135. My issue is that in the quick start guide I can find boosterpack pins functions but it is not clear all of the mentioned are used in case connected to MSP432P401R Launchpad? If there are some used only with EMUBOOST to program the CC3135 boosterpack what happens if I use them in my application with MSP432? Are they inputed or tristated etc..

  • Hi Laszlo,

    The EMUBOOST is used with the BOOSTXL-CC3135 to program the service pack and when Radio Tool is used. 

    • UART is used when programming the service pack: UART1_TX, UART1_RX, UART1_CTS, UART1_RTS, and nHIB.
    • UART or SPI is used when connecting to Radio Tool.
      • UART: same as above
      • SPI: SPI_CLK, CC_SPI_DIN, CC_SPI_DOUT, CC_SPI_CS, cc_IRQ, and CC_nHIB

    Although both SPI and UART can be used when interfacing with a host MCU, our plugin uses SPI. As a result, to leverage the plugin, I recommend to use SPI: SPI_CLK, CC_SPI_DIN, CC_SPI_DOUT, CC_SPI_CS, CC_IRQ, and CC_nHIB

    So now the question is, when these SPI signals are used when working with a host MCU, what is the state of these other signals such as:

    • UART pins
    • CC_NWP_UART_TX, CC_WL_UART_TX, CC_WLRS232_TX, CC_WLRS232_RX (debug pins)
    • DIO_0x (hostless mode GPIOs)

    These pins should be in a Hi-Z state, unless of course the signals like UART are configured not to be in the driver library file.

    BR,
