Forum Post: Grace 3 does not initialize PxOUT

In the comment and code extracted below, it is clear that this routine SHOULD set the PxOUT registers, but it does not in Grace 3.0.  The previous Grace 2 routine GPIO_graceinit did set these registers.  As a workaround I have set them in the user code preamble, but shouldn't Grace do this for you? I believe this is a bug in Grace 3.0.


/*======== PinMux_graceInit ======== * Initialize  * * The PinMux registers should be set in a specific order: * PxOUT * PxSEL or PxSELx * PxDIR * PxREN * PxIES * PxIFG * PxIE * * This will ensure that: * - IFG doesn't get set by manipulating the pin function, edge * select, and pull-up/down resistor functionalities (see * Section 8.2.6 of the MSP430 User's manual) * - Glitch-free setup (configuring the OUT register _before_ * setting the pin direction) * - Pull-up/pull-down resistor enable with the correct direction * (.up. vs. .down.) */ void PinMux_graceInit(void)
