compile error in peripherals.c CMSIS SPI

[rjleiser]

I added FlexConn3 and choose the SPI CMSIS option.

When I route the device and update the code, the code then fails to compile:

undefined reference to `SPI3_SignalEvent' peripherals.c /LPC54606_Project6/board line 419 C/C++

In peripherals.c

static void FLEXCOMM3_init(void) {
/* Initialize CMSIS SPI */
FLEXCOMM3_PERIPHERAL.Initialize(SPI3_SignalEvent);
/* Power control of CMSIS SPI */
FLEXCOMM3_PERIPHERAL.PowerControl(ARM_POWER_FULL);
}

In Peripherals.h:

/* Signal event function for component FLEXCOMM3*/
extern void SPI3_SignalEvent(uint32_t event);

I've tried clean and build. Deleting and then adding FlexConn3 in the peripherals view.

No joy.

The files are read-only anyway...

Any thoughts?

The wise man speaks. Awesomeness.

Thankyou.

Hi, 

It seems that you haven't created the SignalEvent callback. This is expected to be implement in your application code. There is a "Copy to clipboard" button that can provide you a template code that you can just paste to your C module (expecting the peripherals.h is included there).
