Same enum names but different values in fsl_clock.h

[moab]

Hi, 

We are using SDK_2.6.0_LPCXpresso54618and SDK_2.6.0_LPC54605J256 in our project. 

I have faced an issue when I was making a customized uart driver. 

I need to Get clock frequency, so I need to use 

/*! @brief Clock name used to get clock frequency. */
typedef enum _clock_name

and I  aslo need to enable and disable clock, so I need to use

/*! @brief Clock gate name used for CLOCK_EnableClock/CLOCK_DisableClock. */
typedef enum _clock_ip_name 

I need to use both these enums in one file. But this is not possible because they have the same name!!  but different values!! 

example: kCLOCK_Flexcomm0 in the following enums

/*! @brief Clock gate name used for CLOCK_EnableClock/CLOCK_DisableClock. */
typedef enum _clock_ip_name
{
kCLOCK_IpInvalid = 0U,
kCLOCK_Rom = CLK_GATE_DEFINE(AHB_CLK_CTRL0, 1),

Any suggestions on this issue?

Hi Mo,

Both enums are actually in the same header file. So you can use both of them in your program.

The example you comment, kCLOCK_Flexcomm0 has the value of 25 in clock_name_t, and kCLOCK_FlexComm0 has the value of 267 in clock_ip_name_t. The difference is in the lowercase c and the uppercase C. Depending on what you need, you must choose the correct one, according to the argument type in each function.

Best Regards,

Sabina

I didn't notice the difference between 'c' and 'C'. thanks for your reply. My driver works fine now.

Not a problem. Have a great day!
