Hi,
Please provide your sketch. We have no problems with EEPROM.h in another sketches.We need your code to reproduce the error.

Best regards,

Hi, I meant this uint8_t buffer[] = { 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0, 0 }; for (int j = 0; j < HX8357_TFTHEIGHT; j++) { for (int i = 0; i < HX8357_TFTWIDTH ; i++) { memset(buffer, 0, sizeof(buffer)); // You have to setup data before you use a buffer, because it was flooded on previous s...

Hi, Try this code: // ... uint8_t buffer[] = {0,0}; // USE brackets [] for array to define it right way // ... SPI.transfer(buffer, sizeof(buffer)); This have to work. Notice that ucxx will constract the arrays inside the global area, because of small amount of stack for this architecture. So, you c...

Hi, 1) Pin11 is used as OneWire bus pin on the shield. It has pull-up resistor. Seems that's why the relay is always on. 2) Pin12 doesn't have "hardware" pull-up. I don't know why it has logic 1 level in your case. Which type of relay do you use? Is it a module or original electromechanica...

Hi Jack, 1) You can restoreNVM and dumpNVM of EEPROM's "userspace" only. They use the same address area as EEPROM.get/EEPROM.read methods. So you can modify user area of EEPROM. You can't corrupt system area of EEPROM by means of this. 2) Yes, you are right: user configuration parameters o...

Hi, 1. About OLED: the simpliest way is method void fillRect(byte w, byte h, byte fill); oled.gotoXY(needed_x_in_pixels,needed_y_in_pixels/8); oled.fillRect(needed_x_size_in_pixel, needed_y_size_in_pixels/8, 0); 2. If you have some problems with stack don't use map() function. It's to fat for i8051,...

Hi,
please provide a code.

Best regards,

Hi,
It's strange, because it already has #include "Print.h" which includes Arduino_types.h
Please provide an example (sketch code). I didn't see this issue before.

Best regards,

Hi, 1) There is no direct way to add any library from LibraryManager to Z-Uno without "porting". You have to port it first. ZUno has some restrictions in language, in hardware and stack usage. 2) You can find some libraries already ported to Z-Uno inside its cores directory. ZUNO_DHT, ZUNO...

Hi, 1. Add any field to class. For example int a. Your class has no fields. microC++ doesn’t support classes without fields. 2. Please post a code (about double). We will help you. You have to rewrite library a little to make it work with Z-Uno. You can look to libraries folder of Z-Uno cores to see...
