Hi F.Y.
To make any product USB host, you will need Micro-controller with Host capabilities. You can use LPC1700/LPC1800/LPC4300.

Could you please explain in detail?

Hi,

I want to ask more.
I read about nxpUSBlib and how to use it.
But Can we make possible "Mouse Host" use LPC11U24/14 or not?

Regards,

No, you need an MCU with a USB host controller. LPC11U24 only has a USB device controller.

You need an LPC17xx, LPC18xx, LPC40xx or LPC43xx if you want your MCU to act as a USB host.

Hi everyone,

I try to continue make USBMouseHost .
I export mbed UsbMouseHost example and import in to lpcxpresso.
USBHostMouse_HellowWorld_lpcxpresso_lpc1768.zip slight change about cmsis_os.h
add to #define TOOLCHAIN_GCC_ARM. And the it build.
But follow error appear.
./USBHost/USBHost/USBHALHost.cpp:42:24: error: ISO C++ forbids declaration of '__align' with no type [-fpermissive]
../USBHost/USBHost/USBHALHost.cpp:42:30: error: expected ',' or ';' before 'uint8_t'
My environment　LPCXpresso v772_379 and target lpc1769.

Hi everyone,

I know same file was not copy from embed to export project.
That files were some assembly files in LPC1768 folder.
I add that files to LPCXpresso to " USBHostMouse_HelloWorld\USBHost\mbed-rtos\rts".
LPC1768 folder was include ARM and GCC_ARM folders and each folder was same assembly files.
Then I recompile the project. But error is same as this follow line.
static volatile __align(256) uint8_t usb_buf[TOTAL_SIZE] __attribute((section("AHBSRAM1"),aligned)); //256 bytes aligned!
Please same advice for me.
Best Regards,
F.Y

__align(256) is an armcc C extension. You need to move the alignment request into the __attribute__ clause.

Something like the following (untested) definition:

static volatile uint8_t usb_buf[TOTAL_SIZE] __attribute__((section("AHBSRAM1"),aligned(256)));

For more details see:

Hi lpcxpresso-support,

Thank you so much.
It was going to pass. But next error undefined "ret_get_PSP". So I add "GCC_ARM" folder to USBHost\rtx folder.
And also add include path "${workspace_loc:/${ProjName}/USBHost/mbed-rtos/rtx/GCC_ARM}".
I wander why mbed export to lpcxpresso remove these source files. Anyway I success to build and run.
But unfortunately running stop this error.

No source available for "HardFault_Handler() at 0xf8"

I try to debug Step into and I find out the error of this line.

void rt_put_rdy_first (P_TCB p_task) {
/* Put task identified with "p_task" at the head of the ready list. The */
/* task must have at least a priority equal to highest priority in list. */
p_task->p_lnk = os_rdy.p_lnk;
p_task->p_rlnk = NULL;　　　　　　<-------- this line happen'd error
os_rdy.p_lnk = p_task;
}

I can't fix it how to the way.
Could you advice for me something?

Best Regards,
F.Y
