Hi,

Can someone tell me if the ACTBP (Audio capacitive touch booster pack) can be used with the LM4F120 launchpad. ? all references and videos i see refer to the msp430. do i need to 

i set up my arch linux desktop to build the arm toolchain, flash, and debug  it so thats all working nicely wit hth elm4f120. do i need to reprogram  / flash the lm4f120 with a bin file ?. i just want to be able to power it on at this stage :)

    Hi Andy,

    The ACTBP was designed for the MSP430 Launchpad, and includes software specific to the MSP430.

    It seems the LM4F120 Launchpad has the same J1/J2 header dimensions as the MSP430 Launchpad, and voltage supplies, GNDs and signals are in the same pin locations, so the hardware looks compatible with existing BoosterPacks for the MSP430...

    There is no ACTBP software for ARM M4, but you can start by studying the MSP430 host software.

    Below screen shots show that J1/J2 headers are compatible:

    1800 mils = 45.72 mm ≈ 45.76mm

    Hope this helps,
    Mark

    To power on the ACTBP hardware, drive P2.7_PWR_EN to a high level - J2-3 (PE0) on the LM4F120 board.

    When EN of TPS79633 goes to a logic high, the device will be enabled. EN has a pull-down resistor and will default to "OFF".

    Hope this helps,
    Mark
