Wel, well ... I'm confused :oops:
It'OK.
Thank you.

In gfxconf.h, I enable the following settings:
#define GDISP_NEED_TEXT TRUE#define GDISP_NEED_UTF8 TRUE
#define GDISP_INCLUDE_FONT_DEJAVUSANS16 TRUE
when linking, I got this error

I do not understand what I need to do more that inmarket has suggested.
I directly put LCD_Init() code into post_init_board().

Strange Not ?
-
when you manually issue the LCD_Init() routine after gfxInit(), you still use your board file to write the data, right?
Yes.
Do you still have the LCD_Init() routine within the init_board() routine?
Yes. LCD_Init() get executed when init_board() is being called.
static inline void init_board(GDisplay *g) {
// As we are not using multiple displays we set g->board to NULL as we don't use it.
g->board = 0;
switch(g->controllerdisplay)
{
case 0: // Set up for Display 0
LCD_Init();
break;
}

Hi all,
I am using the STM32F103 board with 240x320 TFT (ILI9325). I use uGFX in GOS port mode.
In file board_ILI9325.h, I use the STM stdperiph library functions to control ILI9325 peripheral.
But I have a small problem.
With this code there is no display.
int main(void)
{
coord_t width, height;
/* Setup STM32 system (clock, PLL and Flash configuration) */
SystemInit();
gfxInit();
// Get the screen size
width = gdispGetWidth();
height = gdispGetHeight();
gdispClear(Green);
while(TRUE)
{
gfxSleepMilliseconds(1000); // Wait 1 Sec;
}
}board_ILI9325.h
static inline void init_board(GDisplay *g) {
// As we are not using multiple displays we set g->board to NULL as we don't use it.
g->board = 0;
switch(g->controllerdisplay)
{
case 0: // Set up for Display 0
LCD_Init();
break;
}
}
static inline void write_index(GDisplay *g, uint16_t index) {
(void) g;
LCD_CS = 0;
LCD_RS = 0;
GPIOC->ODR = (GPIOC->ODR & 0xff00) | (index & 0x00ff);
GPIOB->ODR = (GPIOB->ODR & 0x00ff) | (index & 0xff00);
LCD_WR = 0;
LCD_WR = 1;
LCD_CS = 1;
}
static inline void write_data(GDisplay *g, uint16_t data) {
(void) g;
LCD_CS = 0;
LCD_RS = 1;
GPIOC->ODR = (GPIOC->ODR & 0xff00) | (data & 0x00ff);
GPIOB->ODR = (GPIOB->ODR & 0x00ff) | (data & 0xff00);
LCD_WR = 0;
LCD_WR = 1;
LCD_CS = 1;
}But with this code, background display is green !
int main(void)
{
coord_t width, height;
/* Setup STM32 system (clock, PLL and Flash configuration) */
SystemInit();
gfxInit();
LCD_Init();
// Get the screen size
width = gdispGetWidth();
height = gdispGetHeight();
gdispClear(Green);
while(TRUE)
{
gfxSleepMilliseconds(1000); // Wait 1 Sec;
}
} -
Yep with the gfxinit () call, It's OK 8-)

}It's OK with me test function TestgfxSleepMilliseconds() but KO with gfxSleepMilliseconds()
gfxSleepMilliseconds(...) can't return.
This seems to be in gfxYield() function in this line
void gfxYield(void) {
if (!_setjmp(current->cxt)) { .....Rem : I use the bare metal port without any underlying OS.

inmarket, it seems that you are right when you say I suspect the tick timer has not been initialised correctly.
I took the code of gfxSleepMilliseconds() in the following way
void TestgfxSleepMilliseconds(delaytime_t ms)
{
systemticks_t currenttm, starttm, delay;
// Convert delay to ticks
delay = gfxMillisecondsToTicks(ms);
starttm = gfxSystemTicks();
do { currenttm = gfxSystemTicks(); }
while (currenttm - starttm < delay);
}I do not know why the value in currenttm is always less than the value in starttm !
With this test that handle SysTick it's OK

So a timer at 72MHz gets 72 000 000 ticks per second.
/**
* @brief Converts a number of milliseconds to a number of ticks.
* @param None
* @retval a "tick" time
*/
systemticks_t gfxMillisecondsToTicks(delaytime_t ms)
{
uint32_t TicksPerSecond = 72000000;
systemticks_t TicksPerMillisecond = TicksPerSecond / 1000;
return ms * TicksPerMillisecond;
}is this true?
-
Well I find some systick API from the standard peripheral library to implement gfxSystemTicks(void) like this
/**
* @brief Gets a "tick" time from the hardware.
* @param None
* @retval a "tick" time
*/
systemticks_t gfxSystemTicks(void)
{
return SysTick->VAL;
}And in main.c, I call SysTick_Config() function to initialize SysTick
/**
* @brief Main program.
* @param None
* @retval None
*/
int main(void)
{
coord_t width, height;
/* Set the HCLK Clock as SysTick clock source (72MHz) */
/* Setup SysTick Timer for 1 msec interrupts */
SysTick_Config(72000000 / 1000);
.....If I understood for the gfxMillisecondsToTicks() function, you have to convert convert a number of milliseconds to a number of ticks.

I move gfx.h to ../ugfx_lib directory. It's OK.
I place the file board_ILI9325.h in the same directory as gfxconf.h file (in root project directory). It's OK.
I add the ILI9325 gdisp driver files to the compile from the master ugfx source (../ugfx_lib/drivers/gdisp/ILI9325) . It's OK.
I've updated the last image with this information.
It remains to see how to update the board file when using the bare metal port without any underlying OS (RAW32).

OK No worries it is with pleasure 8-)
Christian.

Tectu, Yes, it is exactly that. This wil be a tutorial-like guide to use ugfx with coocox coIDE.
I will now proceed Step 2.
-
Hello,
I'm really new in Coocox CoIDE & uGFX library.
In this topic, I propose to build coIDE project with uGFX library V2.1 for STM32F103RB board.
Excuse me for my poor english, I'm french.
Architecture
- OS Abstractions: BareBone
- Chip: STM32F103RB (Cortex-M3 core)
- LCD controller: ILI9325
- Touchscreen controller: ADS7843
- Audio controller: ADC
Step 1: Default coIDE project
coIDE project basic components :
Common
- C Library: Implement the minimal functionality required to allow newlib to link
- Retarget printf: Implementation of printf(), sprintf() to reduce memory footprint
- CMSIS core: CMSIS core for Cortex M3 V3.01
Boot
- CMSIS Boot: CMSIS boot for STM32
Peripheral
- RCC: Reset and clock control driver.
- GPIO: General purpose I/O ports driver.
- EXTI: External interrupt and event controller driver.
- ADC: Analog to digital converter driver.
- USART: Universal synchronous asynchronous receiver transmitter driver
- MISC: Miscellaneous driver.
I use ARM GCC as the compiler. See CoIDE Compiler Setting.
Step 2: Integrate µGFX with coIDE
Directories
CoIDE compile settings
Set directory of uGFX library in Includepaths. For this example it is ../ugfx_lib
Copy gfx.h & gfxconf.example.h from ugfx_lib (directory of uGFX library) to Test_uGFX (directory of coIDE Project).
In Test_uGFX, rename gfxconf.example.h to gfxconf.h
I use bare metal without any underlying OS, I set GFX_USE_OS_RAW32 option to TRUE in gfxconf.h
You must get this
Step 3: Using GDISP
Enable the entire GDISP module in gfxconf.h (set GFX_USE_GDISP to TRUE).
Copy display config file uGfx library\boards\addons\gdisp\board_ILI9325_hy_stm32_100p.h to board_ILI9325.h in root project directory.
Todo .......

I did what you said.
