Discussion - EVE / create an array of widgets
« on: April 06, 2021, 11:11:21 AM »
Hi,
On ESD it's impossible to create an array of widgets, all widget of the same type must have a different name on design time.
Should I use custom source code to use them in array mode or in dynamic array mode (malloc)?

Discussion - EVE / Autoresize label width
« on: April 02, 2021, 04:34:58 PM »
I'd like to resize the width of my labels function of its content in a linear layout to avoid spare distance between labels.
But I saw that autoresize height works great but width is not working. How can I do that?

Discussion - EVE / Render the screen only when there is a change in ESD
« on: March 19, 2021, 09:56:13 AM »
Hi,
In my screen I have multiple variables which are connected to text property of ESD labels. When render is called, text is refreshed each time, even if variable value doesn't change with spi transferts useless.
How to avoid this?

Discussion - EVE / Display a loading page with ESD
« on: February 24, 2021, 09:41:53 AM »
Hi,
I'd like to display a loading page with progressbar during inflating or loading of image and fonts...
How to make this?
If I load an image in SPI flash of EVE from MCU flash, and I restart esd application, how can I detect that image is already in eve flash to not reload it?

Discussion - EVE / ESD with rtos threadx
« on: February 24, 2021, 09:27:02 AM »
Hi,
We're migrating our monothread project on simple LCD display to EVE display.
I use 2 threads: one for display with EVE ESD project UI and an other for our own library. This library must send events info, data structures, event for displaying and synchronysing with UI thread.
For example our library must send an event to change of EVE page or to display or not some widgets.
There is no examples of this implementation/architecture.
How can I handle this easilly?
Regards

Discussion - EVE / ESD 4.10 display instabilities
« on: February 08, 2021, 01:28:03 PM »
Hi,
I 've made a screen with ontly 3 labels rendered in the normal loop of ESD4.10 exported eclipse project on a renesas synergy MCU.
I've enabled _DEBUG preprocessor.
It can display 10 minutes without errors and suddenly
I encounter many display glitches and hanging randomly:
- "illegal option in cmd_text"
- bad characters
- screen becomes black but program runs normally in background and i'm unable to unlock it since there is no error detected. I must unplug power to unlock it.
It's like BT815 was in a normal state but not the screen...
Modify SPI bitrate changes nothing.
Do you know what the cause?

Discussion - EVE / error on custom ESD_METHOD in source file
« on: December 10, 2020, 01:24:50 PM »
I want to control backlight level of my screen with this function :
In C file:
In H file:
But I get an error that I can't resolve:
"C:/Program Files (x86)/EVE Screen Designer/NewProject3/Usr_AnimateLogo.h:16: error: ',' expected (got "*")"
I don't understand what that means?
In C file:
Code: [Select]
void APP_Screen_AdjustBrightness(Usr_Settings *context, int percentlevel)
{
Ft_Gpu_Hal_Context_t *phost = Ft_Esd_GetHost();
uint8_t Value = 0x80;//0 to 128
if(PercentLevel<=100)
{
Value = (uint8_t)((PercentLevel*128)/100);
}
EVE_Hal_wr8(phost, REG_PWM_DUTY, Value); // Backlight PWM duty
}
In H file:
Code: [Select]
#include "Ft_Esd.h"
ESD_METHOD(APP_Screen_AdjustBrightness, Context = Usr_Settings, Type = void)
ESD_PARAMETER(percentlevel, Type = int, Default = 100, Min = 0, Max = 100)
void APP_Screen_AdjustBrightness(Usr_Settings *context, int percentlevel); //error here
But I get an error that I can't resolve:
"C:/Program Files (x86)/EVE Screen Designer/NewProject3/Usr_AnimateLogo.h:16: error: ',' expected (got "*")"

Discussion - EVE / Bug when using special character set with user font and ESDlabel
« on: December 03, 2020, 11:50:33 AM »
I'v added special characters like é, è, à to a font because I must use french language. Rom fonts doesn't have these characters! It's too bad.
When I use an ESDlabel and I write "é" followed by a character from "0" to "f" (hexadecimal), this character becomes a space. Other characters are displayed correctly.
Can you reproduce it and correct it?

Discussion - EVE / Possibility to capture frame buffer to bring remote control functionality

Is it possible to read the actual frame buffer of the screen to get an image to send it to a remote control client?

Discussion - EVE / Porting ESD4.8 project to renesas synergy platform
« on: October 09, 2020, 11:10:28 AM »
Hi community,
I've exported ESD4 project to eclipse format and i've succefully ported the library to renesas synergy platform!
I use it because I can previsualize screen before code them and there is more widgets than with ESE.
But I have many questions and recommandations for Bridgetek developppers and community:
1) There are lot of warnings in the project (about 3300). It's mainly conversion variable formats and definition function problems. Can you correct this?
2) When you use NULL constants include of stddef.h is missing.
3) In ft_esd_cocmd_widgets.c include of stdarg.h is missing for va_arg() function use.
4) I have a matrix orbital screen without touch screen since I'm using a keypad appart: library is not optimized for TPN screen references. Is it possible to autodetect that a touchscreen controller is physically present or not with BT815? Or add a define to support TPN configuration? I must consequently disable esd_calibrate() function.
5) If there is no SPI flash connected to BT815, is it possible to display bitmaps? I have only the flash on my MCU and maybe SPI flash extension later. Library is also not optimized for non SPI flash devices.
6) I have 4.3inch 480x272 resolution WQVGA screen and I've edited EVE_config.h to make it work with :
#ifndef EVE_DISPLAY_AVAILABLE
#define EVE_DISPLAY_AVAILABLE
#define DISPLAY_RESOLUTION_WQVGA //WVGA before
#endif
As you can see, when I export to eclipse project I must modify several files each time to compile successfully my project. It's borring...
The other solution is to export outside my project and copy only modified files...
Regards.
