Im getting this error DescriptionResourcePathLocationType
'LPC_IOCON_T' has no member named 'PIO1_6'ccan_rom_w.c/nxp_lpcxpresso_11c24_periph_ccan_rom/example/srcline 319C/C++ Problem

I am using the LPCOpen c_can project via LPCXresso 7.8 on the LPCXresso 11C24 board and adding uart functionality via and example from the Joseph Yiu book. Despite including the LPC11xx.h via the per file property it fails to see the LPC_ICON struct which is clearly defined in the LPC11xx.h file. If I include the header manually I get all kinds of duplicate definition errors. I have read the http://support.code-red-tech.com/CodeRedWiki/PerFileProperties and googled my brains out over this.

Original Attachment has been moved to: LPC11xx_0.h.zip

Original Attachment has been moved to: simple_uart.h.zip

You shouldn't copy board or chip files in your project. Or older CMSIS files. That's confusing the compiler and that's confusing you :((

You are/were so right about this. Thank you for spotting that in my project, turns out it was the linch-pin to many of the issues Ive been having. Ive forgone attempting to manually link headers and deferred solely through the project properties fx of the compiler and now all the files are playing together nice :). Just need to sort out the label decorators.
THANKS

Agreed :). That was my attempt to cobble things together initially. Still learning how to link w this compiler.

If there are registers missing it's useful to add them, as described here:

Thanks, will check it out

So its pretty mangled.

:)

That's a cruel mixture...

If it's necessary to access registers it's useful to look into Chip or Board library. There are a lot of functions available and you can also see there correct register names ;-)

Thnaks, now i can upload projects

So its pretty mangled. I deleted the simple_uart.c and most of .h out of frustration and to get you method to work

...is there a faq for uploading the project?

Just export and upload it?

Without project I'm not sure what you are doing in detail :((

I attempted to, but was only able to attach the source files,is there a faq for uploading the project?

So obviously LPCOpen is now using an array (REG[]) to access IOCON registers. CMSIS was using single IOCON register names like PIO1_6.

Mixing both methods isn't recommended and usually not necessary...

I agree and think you nailed it. I am at a loss on how to rectify. Im not understanding how the compiler is linking projects/headers within the workspace.

This works, thank you. But why doesnt what I proposed above?

After receiving:

Quote:
LPC_IOCON_T' has no member named...

it's time to check IOCON. With 'Open declaration F3' you'll find in chip.h:

#define LPC_IOCON                 ((LPC_IOCON_T            *) LPC_IOCON_BASE)

and

LPC_IOCON_T in iocon_11xx.h:

typedef struct {/*!< LPC11XX/LPC11XXLV/LPC11UXX IOCON Structure */
__IO uint32_t  REG[48];
} LPC_IOCON_T;

So obviously LPCOpen is now using an array (REG[]) to access IOCON registers. CMSIS was using single IOCON register names like PIO1_6.

This works, thank you. But why doesnt what I proposed above? Im really struggling w paths and inclusive errors w this compiler.

What about using LPCOpen :~

Chip_IOCON_PinMuxSet(LPC_IOCON, IOCON_PIO1_6, (IOCON_FUNC1 | IOCON_MODE_INACT)); /* RXD */

As shown in UART setup of board.c

/* Initialize debug output via UART for board */
void Board_Debug_Init(void)
{
#if defined(DEBUG_UART)
Chip_IOCON_PinMuxSet(LPC_IOCON, IOCON_PIO1_6, (IOCON_FUNC1 | IOCON_MODE_INACT)); /* RXD */
Chip_IOCON_PinMuxSet(LPC_IOCON, IOCON_PIO1_7, (IOCON_FUNC1 | IOCON_MODE_INACT)); /* TXD */

/* Setup UART for 115.2K8N1 */
Chip_UART_Init(LPC_USART);
Chip_UART_SetBaud(LPC_USART, 115200);
Chip_UART_ConfigData(LPC_USART, (UART_LCR_WLEN8 | UART_LCR_SBS_1BIT));
Chip_UART_SetupFIFOS(LPC_USART, (UART_FCR_FIFO_EN | UART_FCR_TRG_LEV2));
Chip_UART_TXEnable(LPC_USART);
#endif
}
