looking at ..._discovery_sdram.c looks like all the codes related to the SD RAM intialiazation, access etc.. So I don't have to write this right ? since I am trying to use the embedded ram. I will look into the stm32ltdc.. am I correct ?
-
Hi, i remember I got started with ugfx by using some template project file, But now I am trying to build my own PCB to keep the cost at ultimate low I want to eliminate many external component on STM32f7-Discovery board..
Main concern is I don't know how to make ugfx to only use the internal ram on the MCU it self.
Anyone has any idea how to go about this ?
-
any example to do that ?
-
Is there any other virtualkeyboard than the rectangular one.. I was finding for like a dial numeric keypad.
Similar to image attached
-
Is there a way to keep the image open,
gdispImageOpenFile(&myImage, "spices.BMP"); gdispImageDraw(&myImage, 0, 0, 480, 272, 0, 0);
the image will be closed after the function is completed
-
that is in your GFILE demo module... maybe U can make the changes in you repo if its wrong....

Hi @Joel Bodenmann and @inmarket
is this is a spelling error below at the if condition you spell it as logfile in small cap but then the GFILE object is logFile ?
void LogInfo(const char* msg) { GFILE* logFile; logFile = gfileOpen("info.txt", "a"); // Open the file for append if (logfile) { gfileWrite(logFile, msg, strlen(msg)); gfileClose(logFile); // Close the file again } }

hi thanks for reply but do you mind to give some hint, debug for ?....
What should I do when I am doing debugging in stuck into gfxHalt, what should I do after I encounter halt ?
-
Hii all, I got my fatfs working but when I try sample code it always goes and stuck gfxHalt(),
i tried two type gfx.conf but not working
First Time :
#define GFILE_FATFS_EXTERNAL_LIB TRUE #define GFILE_NEED_NOAUTOMOUNT TRUE #define GFILE_NEED_PRINTG TRUE
Second Time :
#define GFILE_NEED_FATFS TRUE #define GFILE_NEED_NOAUTOMOUNT TRUE #define GFILE_NEED_PRINTG TRUEBoth ways It ugfx FATFS DEMO don't work for me, I am doing wrong anywhere ?
-
Alright thanks for that.
..
I was confused with linker file script.
-
the value of GFX_OS_HEAP_SIZE is in HEX bytes right,
Eg if GFX_OS_HEAP_SIZE == 1000 in gfx.conf then it's around 4KB, Am I correct ?
-
Hi, thanks for your reply. I will try to fill the heap with known patter and see. and when I set the gfx_os_heap_size does it mean it's dynamically allocated only for ugfx usage and could not conflict with other code section that uses malloc ?.
-
I see, thanks to pointing it out. Is there anyway to monitor my stack and heap real time ?..... I am using the stm32f7 dis board package, so the uGFX only uses the internal ram during code execution and the external ram only for frame buffer ? am I right ?
-
hi also found out why my own implementation of keyboard don't work but gwin example worked as mentioned last time is because few defination in ugfx config
//#define GEVENT_ASSERT_NO_RESOURCE FALSE
//#define GEVENT_MAXIMUM_SIZE 32 //dEFAULT VALUE: 32
//#define GEVENT_MAX_SOURCE_LISTENERS 3 //dEFAULT VALUE: 32commenting out the three stuff got my gevent listening to my keyboard, do you mind to tell why it happens
-
Thanks Joel.. Yes cubemx provide one. doing my hello world interface with sd card
-
Can anyone tell where should I start to use GFILE and interface with FATFS on stm32 sd card ?, more on how to set up the diskio stuff
-
Oh, I am running on a raw32 bare metal platform, BTW I will try the malloc suppose the std c lib should provide it
-
Hi, got it working using the demo file but I noticed the keyboard is only displayed on screen if I define below statement, heap size
#define GFX_OS_HEAP_SIZE 2000
, mind to tell why ?. BTW how to estimate hw much stack and heap size is required for my uGFX GUI implementation ?
.

Sorry, I hope someone will help.
I do look at demo/modules/gwin/keyboard.
Below is my code I tried but no luck, moreover I try setting breakpoint at few lines related to keyboard it's did not stop anywhere. Which means my key presses are not listened at all. How do I go about is it uGFX config or bugs or etc. Anyone who have done reading char from keyboard event mind to help ? and is my english bad that most of you guys don't understand what I am talking about ?
Cheers !
if (((GEventKeyboard*)pe)->bytecount >0)
{
pk = (GEventKeyboard *)pe;
for (int x =0; x < 4; x++)
{
dynamic_array[x] = (uint8_t)pk->c[x];
dynamic_array[1]++;
//gwinPrintf(ghTextedit1, "ERROR");

The documentations is quite poor, but I know you are very busy with uGFX dev.. which most likely need to dig down the code to understand what's happening. I am very confused between gwin_keyboard and keyboard.. How do we read a char from gwin_keyboard ? I am only receiving the trigger for GEVENT_GWIN_KEYBOARD in switch statement only when I press return button no reaction when I press characters like a b c d and so on. What I have tried to change the parameter of source attachers geventAttachSource(&glistener, gwinKeyboardGetEventSource(ghKeyboard1),GLISTEN_KEYTRANSITIONS|GLISTEN_KEYUP); GKEYBOARD_ALL_INSTANCES) none of this seems to help me.. I really hope there is a documentations says how to attach the source from gwin_keyboard(virtual) to listener and how to retrieve each character from the virtual keyboard. Can you help me clear this doubt out. I promise I will write a brief explanation a-z for new uGFX comers to use the library with ease.
-
Hi @Joel Bodenmann, I am having the button and the virtual keyboard in a same page but I want to disable my virtual keyboard event to my button. I want the button to work individually
-
Even copying your sample code doesnt work, it seems it's not listening to my virtual keyboard at all.. I tried putting break point and test where else for button it was working very well
-
Does the code below made sense ? I cast the pe (which is geventWait return ) to a GEventKeyboard but seems I cannot access the byte.. Am I doing anything wrong ?
pe = geventEventWait(&glistener,TIME_INFINITE );
switch (pe->type) {
{
case GEVENT_GWIN_BUTTON:
if (((GEventGWinButton*)pe)->gwin == touch_button_df_pg) {gwinDestroy(ghContainerPage0);
guiCreate();
//gwinPrintf(ghTextedit1, "fgdfg");
// createPagePage1();
// guiShowPage(1);
//(((GEventGWinButton*)pe)->gwin == ghButton1)
break;
}
else if (((GEventGWinButton*)pe)->gwin == ghButton1) // main page
{
gwinHide(ghContainerPage1);
gwinDestroy(ghContainerPage1);
createPagePage0();
guiShowPage(0);
break;
}
}
break;
case GEVENT_GWIN_KEYBOARD || GEVENT_KEYBOARD:
{
if (((GEventKeyboard*)pe)->bytecount >0)
{
pk = (GEventKeyboard *)pe;
for (int x =0; x < 4; x++)
{
dynamic_array[x] = (uint8_t)pk->c[x];
dynamic_array[1]++;
//gwinPrintf(ghTextedit1, "ERROR");

Hi @Joel Bodenmann, but the button should be always in focus to read the input right, if that's the case how do I stop the distribution virtual keyboard events to widgets ?

Hi, I am planning to to show a random images as screen saver but upon any touch on screen I want to render a page, How can I do the detecting the touch part ?
