[how to run demo on pc with code::block]

I want to run a demo on pc with code::block. I create a new empty project. And I add the file to the project. But the project do not run, I do not know how to set the project.

[how to implement a key driver ?]

Now, I have completed a key driver,

#define GINPUT_TOGGLE_NUM_PORTS			3			// The total number of toggle inputs
#define GINPUT_TOGGLE_CONFIG_ENTRIES	1

#define GINPUT_TOGGLE_DECLARE_STRUCTURE()											\
const GToggleConfig GInputToggleConfigTable[GINPUT_TOGGLE_CONFIG_ENTRIES] = {	\
		{GPIOC,								\
			GPIO_Pin_7 | GPIO_Pin_8 | GPIO_Pin_9,											\
			GPIO_Pin_7 | GPIO_Pin_8 | GPIO_Pin_9,											\
			GPIO_Mode_IN}													\
	}

	
GINPUT_TOGGLE_DECLARE_STRUCTURE();

void ginput_lld_toggle_init(const GToggleConfig *ptc) 
{
	key_init();
}

unsigned ginput_lld_toggle_getbits(const GToggleConfig *ptc) {
	return GPIO_ReadInputData(GPIOC);
}

if the key GPIOC.7 is pressed, how do I check the key event in a win ?

[how to implement a key driver ?]

I want to implement a key driver. And I see the example in the gdrivers.

GINPUT_TOGGLE_DECLARE_STRUCTURE();

void ginput_lld_toggle_init(const GToggleConfig *ptc) {
	palSetGroupMode(((IOBus *)ptc->id)->portid, ptc->mask, 0, ptc->mode);
}

unsigned ginput_lld_toggle_getbits(const GToggleConfig *ptc) {
	return palReadBus((IOBus *)ptc->id);
}

// Describes how the toggle bits are obtained
typedef struct GToggleConfig_t {
	void		*id;
	unsigned	mask;
	unsigned	invert;
	unsigned	mode;
} GToggleConfig;

But I have no idea how to write the code, is there a example ? what's the mean of invert ?

I use in bare metal mode.  no palSetGroupMode() function, no IOBus * type

[gfxSleepMilliseconds() stuck?]

thanks for you !

my mcu is stm32F407, I use the STM32F4xx_DSP_StdPeriph_Lib_V1.7.1. I am using  bare metal mode, keil 5.

SysTick_Handler()  get called. Because delay(250) is OK. I am using the UGFX 2.7.

[gfxSleepMilliseconds() stuck?]

I  run the demo arcsectors. But the gfxSleepMilliseconds()  stuck.

here is my code

int main(void)
{        
    coord_t        width, height, r1, r2, cx, cy;
    uint8_t        sectors;
    
    SysTick_Config(SystemCoreClock / 1000);    
    NVIC_PriorityGroupConfig(NVIC_PriorityGroup_2);    
    lcd_init();    
    win_flash();    
    delay(1000);
    lcd_clear();
    
    gfxInit();
    
    // Get the screen size
    width = gdispGetWidth();
    height = gdispGetHeight();

    // Initialize some variables
    r1 = width > height ? height/3 : width/3;
    r2 = r1*3/4;
    cx = width/2;
    cy = height/2;
    sectors = 1;
    
    while(1) {
        // Draw the arc sectors
        gdispClear(White);
        gdispDrawArcSectors(cx, cy, r1, sectors, Black);
        gdispFillArcSectors(cx, cy, r2, sectors, Black);

        // Increase the sectors counter
        sectors++;

        // Waste some time
        gfxSleepMilliseconds(250);
    }
}




static volatile uint32_t gfx_tick = 0;
static volatile uint32_t cnt = 0;

systemticks_t gfxSystemTicks(void)
{
    return gfx_tick;
}
 
systemticks_t gfxMillisecondsToTicks(delaytime_t ms)
{
    return ms;
}


void SysTick_Handler(void)
{    

    gfx_tick ++;
    
    if (0 != cnt)
        cnt--;
}

extern void delay(uint16_t val)
{
    cnt = val;
    while(cnt);
}

if I replace the gfxSleepMilliseconds(250) with delay(250), it is OK. what is wrong with it ?
