Hi,

For some projects, I need to have the Text property of an ESD_TextBox to be editable ( I need it a.o. for a OS_Keyboard )
I looked in the Keyboard example and saw the use of "cstring" there. As I wanted so be sure that each instance has it's own storage, I checked the generated code.

To my asthonisment, I saw that in the EVE_Header files "cstring" is just a typedef of "const char*" which in turn means, that I will be writing directly in "some" memory where the default value is kept 

Is there anybody out there who can wake me up from this bad dream  I am probably missing something, but can't figure out what.

Greets and already thanks for an answer,

Here comes the HALimpl

It is based upon Rudolph's Arduino Library as an API to the Arduino.

The App_Generated.c file is output from ESD. It just needs commenting out the "main()" function and the Application definition.

like this:

//static App application;
//static Esd_Context s_Esd;

void App__Start(App *context)
{
App__Initializer(context);
App_Start(context);
}

//int main(int argc, char *argv[])
//{
// Esd_Initialize();
//
// {
// Esd_Parameters ep;
// Esd_Defaults(&ep);
// ep.UserContext = &application;
// ep.Start = (Esd_Callback)App__Start;
// ep.Update = (Esd_Callback)App_Update;
// ep.Render = (Esd_Callback)App_Render;
// ep.Idle = (Esd_Callback)App_Idle;
// ep.End = (Esd_Callback)App_End;
// if (!Esd_Open(&s_Esd, &ep))
// return EXIT_FAILURE;
// }
// Esd_Loop(&s_Esd);
// Esd_Close(&s_Esd);
//
// Esd_Release();
// return EXIT_SUCCESS;
//}

which is then replaced in the .ino by:

void setup()
{
pinMode     (SWITCH,  INPUT);

pinMode (EVE_PDN, OUTPUT); // keep EVE in Reset (PD ==> PowerDown)
digitalWrite(EVE_PDN, LOW);

pinMode (PIN_SPI_SS, OUTPUT);
digitalWrite(PIN_SPI_SS, HIGH); // deselect EVE

pinMode (PIN_SPI1_SS, OUTPUT);
digitalWrite(PIN_SPI1_SS, HIGH); // deselect Flash

pinMode (PIN_SPI2_SS, OUTPUT);
digitalWrite(PIN_SPI2_SS, HIGH); // deselect FPC

pinMode     (LED_BUILTIN, OUTPUT);
digitalWrite(LED_BUILTIN, HIGH);

SerialUSB.begin(115200); // USB
Serial1 .begin(  9600); // ES_Link
Serial2  .begin( 16667); // LocoNet

Flash.begin(SPI1, PIN_SPI1_SS); // SerialFlash does the SPI startup by itself

SPI2.begin(); // start the display SPI
init_ST7701_Display(); // configure and start the display

SPI.begin(); // startup EVE's SPI
SPI.beginTransaction(EVE_SPI_SETTINGS);

TFT_init(); // Make EVE start working
TFT_display();

  delay(500);
arduino_printf("hello, Display is up :)");

int times = 180;
while (times--) {
  delay(26);
  TFT_display();
rotate += 2;
}

if (digitalRead(SWITCH) == 0) {
TFT_calibrate();
while (digitalRead(SWITCH) != 0);
while (digitalRead(SWITCH) == 0);
}

arduino_printf("hello, EVE is up :)");

Esd_Initialize();

Esd_Parameters ep;
Esd_Defaults(&ep);

ep.UserContext = &application;
ep.Start = (Esd_Callback)App__Start;
ep.Update = (Esd_Callback)App_Update;
ep.Render = (Esd_Callback)App_Render;
ep.Idle = (Esd_Callback)App_Idle;
ep.End = (Esd_Callback)App_End;

if (Esd_Open(&s_Esd, &ep)) {
EVE_HalContext* phost = &s_Esd.HalContext;
Esd_SetCurrent(&s_Esd);
Esd_Start(&s_Esd);

Esd_Started = true;

application.App_Screen.Main_Page.DDC_Logo_Input    = DDC_Logo_Input;
application.App_Screen.Main_Page.DCC_Logo_Rotation = DDC_Logo_Rotation;
}
else {
TFT_display();
}

SerialUSB.println("setup() done");
}


that's "setup()"

and in "loop()"

display_delay++;

// refresh the display every 20ms or 5 ms when ESD is running
if (display_delay > 4) {
display_delay = 0;

micros_start = micros();

if (Esd_Started) {
if (toggle_state != 0)
if (++rotate == 360)
rotate = 0;

Esd_Update (&s_Esd);
Esd_Render (&s_Esd);
Esd_WaitSwap(&s_Esd);
}
else
TFT_display();

micros_end = micros();

num_profile_a = (micros_end - micros_start); // calculate the micro-seconds passed during the call to TFT_display
}

Hi,

Thanks for the info (y)

I will try and let you know the result

Hi,

Self-answer to Question 2:

Compilation failed!
I tried to compile this:

/*

The tiny language resembles C in syntax.

It allows:
  - functions, of "void" and "int" type
  - constructs, if .. else, while and do .. while loops
  - local variables, of "int" type only
  - integer arithmetic (no / or %)

The end-user defines three functions:
  - i2c_addr() which returns the I2C address
  - setup() one-time initialization
  - loop() poll the CTP and update the touch sensing registers

In addition a number of built-in functions are available for IO in the user's code. Together these form a simple HAL.

  - void delay_ms(n)              // delay for n milliseconds
  - void delay_us(n)              // delay for n microseconds
  - void i2c_regwr(u, v)          // write value v to register u
  - void i2c_startread(u)         // start a read from register u
  - int i2c_read16le()            // read 16 bits from I2C, little-endian
  - int i2c_read16be()            // read 16 bits from I2C, big-endian
  - int i2c_read8()               // read 8 bit from I2C
  - void i2c_stop()               // end the I2C read
  - void report_touch(id, x, y)   // set the touch sensing registers
  - int getINT()                  // get the INT input
  - void setINT(u)                // set INT open-drain
  - void setWAKE(u)               // set WAKE output
  - int getCYA()                  // get the CYA register value
*/


/* This code assumes CTP reports n_touches = 0 during last touch interrupt at finger-up */
int i2c_addr()
{
  return 0x38;
}

int setup()
{
  setWAKE (0);
  delay_ms(3);
  setWAKE (1);
  delay_ms(300);
}

//void rtouch()
//{
//  int x    = i2c_read16be() & 0xFFF;
//  int id_y = i2c_read16be();
//
//  report_touch(id_y >> 12, x, id_y & 0xFFF);
//}
//
//void loop()
//{
//  while (getINT() == 1) // wait for INT to go low
//    ;
//
//  i2c_startread(0x02);
//
//  int n_touches = i2c_read8();
//
//  while (n_touches != 0) {
//    rtouch();
//    n_touches = n_touches - 1;
//  }
//
//  i2c_stop();
//}
So loop() is mandatory.

Is it possible to post the source code of the ROM-micro-code for the GT911 ?

Hi,

A little progress-report

ESD will generate the ANSI C code for the selected platform.
Arduino is using its own C++ variety language to program. 
However, I think it is possible to build C for MCU on the Arduino board. 

Yes it is. But it can either have all it's code together with it's INO file or in the libraries folder each library in it's own directory.

So the trick I used is using "Junction-Links" to an MSVC exported version's generated libraries ( see attachment 1 ), then just listing the "main" header files of the ESD generated code in the INO ( see attachment 2 ) .

This will automagically pull-in all the ESD generated code 

But... since ESD relies heavily on compile-time defines, the last thing is to take these defines from the MSVC project file and enter them in the Arduino boards.txt definition file as "extra_flags"

Then when it all compiles error free, it will generate a bunch of "undefined references" during link-time. ( only when also "App.h" is also present in the INO )

So...

You may need to modify the code in the HAL of the ESD-generated application. You may refer to this porting guide:

Yep, better not modify, but write your own HAL_Impl. Which is my next challenge

All the new platform definition stuff is done by editing EVE_Config.h, EVE_util.h, EVE_util.c and EVE_Platform.h ( if anybody is interested, tell me, I'll upload them here )

Hi Paul,

Thanks for the link, I will study it and see what's in there for me

At first glance, it looks like exactly what I need !
