EEPROM emulation #2
Description
STM32 has EEPROM emulation.
So i change this code
[Current]
#if defined(ARDUINO_ARCH_STM32)
//FT81XMANIA TEAM (@lightcalamar)
///////////////////////////////////////////////////////////////////////////////////////////////////////
AT24Cxx eep(i2c_address, 32);
if (eep.read(0) != 0x7c) {
self_calibrate();
for (int i = 0; i < 24; i++)
eep.write(1 + i, GDTR.rd(REG_TOUCH_TRANSFORM_A + i));
eep.write(0, 0x7c); // is written!
} else {
for (int i = 0; i < 24; i++)
GDTR.wr(REG_TOUCH_TRANSFORM_A + i, eep.read(1 + i));
}

[Edit]
#if defined(__STM32F1__)
uint16 Status;
uint16_t Data;
Status = EEPROM.read(0x10,&Data);
Serial.print("Data.EEPROM[10]=");
Serial.println(Data,HEX);
if (Data != 0x7c) {
self_calibrate();
for (int i = 0; i < 24; i++) {
Data = GDTR.rd(REG_TOUCH_TRANSFORM_A + i);
Serial.print("Data.rd[" + String(i) + "=");
Serial.println(Data, HEX);
EEPROM.write(0x20 + i, Data);
}
EEPROM.write(0x10, 0x7c); // is written!
} else {
for (int i = 0; i < 24; i++) {
Status=EEPROM.read(0x20+i,&Data);
Serial.print("Data.EEPROM[=" + String(i) + "]=");
Serial.println(Data,HEX);
GDTR.wr(REG_TOUCH_TRANSFORM_A + i, Data);
}
}
#endif

Hello @nopnop2002
Thank you for your cooperation. Can you tell which Arduino core you are using with your STM32F1 board?
nopnop2002 commentedon Apr 9, 2018
I'm using this core.
https://github.com/rogerclarkmelbourne/Arduino_STM32
If you use EEPROM emulation,you don't need any external chip.
lightcalamar commentedon Apr 9, 2018
Yes. Exact.
If using Arduino_STM32 core, it does not make external EEPROM data. However in README.md we recommend using core for STM32GENERIC by Danieleff , installation for IDE Arduino with STM32 boards, then if you need external EEPROM, core Arduino_STM32 does not have support for F407, F429 or F767, although if STM32GENERIC by Danieleff offers support to STM32F1 and much more example; core 144 pin the F4 family etc ...
Be interesting and be able to increase the power of this library by supporting more cores.
Thank you!

OK
I respect your opinion.
I'll make a library of STM32F103 exclusive use by making reference to your library.
Please close this isuue.
Thank you.

Thank you @nopnop2002 .However, I will include your code and make a bigger library.
Finish installing new core, specifically Huaweiwx https://github.com/huaweiwx/STM32GENERIC, this generic core of STM32 for Arduino, have an emulation library of EEPROM and I think it works as in STM32_duino core.
Conduct tests right now with my Nucleo-F767 board, and work up to serial monitor. Then be very interesting, include code.
Thank you!

OK
I'm waiting your new library to be completed.
Thank you.
