The default initialization of the array elements is 0. If you use the array of the type of the `Float` or the` Double` type, the default initialization is the `nan`. If the array is too large, it may exceed Arduino's memory limit, resulting in the program cannot run. The...

The MAC address is defined as an array of bytes, each of which is represented as a pair of hexadecimal digits (thanks to the 0x preceding each number). The IP addresses of the shield, the DNS and the gateway is given as an object of class IPAddress, as well as the subnet mask (...
We have already looked at the Arduino GIGA board, an incredibly powerful microcontroller in the same format as the classic Arduino Mega 2560. Today we will look at an upgrade for the GIGA, a “shield” that is actually more of a “reverse shield” (this will make more sense as you read...
jolliPOV have an array of 16 LEDs on it, it would be good to use a large size font for display. We searched online and found an amazing article by George Gardner showing how we can create a font from one of your computer’s TrueType fonts that’s easily scalable to any size of LED...
It’s a 6-Bytes array each byte of which is represented by 2 hexadecimal digits that can take any value between (0…9-A…F). And it doesn’t matter if the letters are upper-case or lower-case. The MAC address: 25:3A:42:CE:B7:FF is perfectly the same as 25:3a:42:ce:b7:ff...
Arduino treats arrays in much the same way as C++ and somewhat like Processing, though you cannot use the constructor with an array as with Processing. The same rules about what can be stored in the array apply: int intArray[10]; intArray[4] = 4; intArray[3] = "hello!"; // doesn...
As you said, the array is too big for Arduino: c:\Users\Admin\Documents\Arduino\libraries\U8g2\src\clib\u8g2_fonts.c:111831:15: error: size of array 'u8g2_font_wqy12_t_gb2312' is too large const uint8_t u8g2_font_wqy12_t_gb2312[202690] U8G2_FONT_SECTION("u8g2_font_wqy...
proper type promotion or conversion is performed, if allowed): Strikethrough mine 'cause that don't work here (and it's not my fault nor under my control - it's supplied with avrlibc, and I suspect that it's because the overhead of implementing it on an 8-bit AVR is too large)....
