Config File Overwritten by MikroC GUI

[ack23]

I am no MPU expert, but it seems strange to me that the MikroC GUI overwrites my .cfg file in a way that stops the MPU from functioning with HID library.

As a work around I set my .cfg file as read only. Strangly, the GUI only complains about this occasionally.

However, I would like to understand what is causing this.

I am using the HID library, so I got the .cfg from there as a starting point, since I have no idea how to configure clocks etc for HID.

I also do some config in the code. E.g.:

//----------------------------------------------------------------------------------------------
// external intr setup
GPIO_Digital_Input(&GPIOC_IDR,_GPIO_PINMASK_4); //was 1
SYSCFGEN_bit = 1; // Enable clock for alt pin functions
SYSCFG_EXTICR2 |= 0b0000000000000010; // Map external interrupt on PC4
EXTI_RTSR |= 0b0000000000010000; // Set intr on Rising edge (PC4)
EXTI_FTSR |= 0b0000000000000000; // Set intr on Falling edge (none)
EXTI_IMR |= 0b0000000000010000; // Set mask
// enable is done later
NVIC_SetIntPriority(IVT_INT_EXTI4, _NVIC_INT_PRIORITY_LVL13);

NVIC_SetIntPriority(IVT_INT_OTG_FS, _NVIC_INT_PRIORITY_LVL15); // lowest
// ----------------------------------------------------------------------------------------------

and misc timers.

But is not clear to me why the GUI wants to overwrite my .cfg file.

Presumably, something I am doing in the code causes the compler to want to change the .cfg. It just stops HID from working.

Any throughts?

Hi,

Can you please tell me which MCU and compiler version are you using ?
Does this happen with every project or a specific one ?
Is there a way to reproduce this (a pattern) ?

Regards,
Filip.

Thanks for your response.

I am using mikroC Pro for ARM v.6.2.0-D, and the Mini-M4 module.

However, I think the was happening for ealier versions.

It happens with all the projects where I start with the HID library example, and start off using the .cfg file that comes with that.
