The 'mask' is used to select one bit from 'data'.h” in the . If you want to pass a primitive, you can consider using references or pointers if the size of the primitive is larger than the size of the pointer. On the Uno and other ATMEGA based boards, unsigned ints (unsigned integers) are the same as ints in that they store a 2 byte value. Fortunately, the implementation in provides an option to speed things up … Hello guys.
Therefore, by using a pointer to reference a value, you can save 1 byte of SRAM. ESP32 - Storing and retrieving uint8_t type arrays permanantly. Tommy56 December 22, 2019, 7:59pm 2. I've put a .

The first thing to say is that you do not have a string to convert to an integer, you have a String. I haven't used C since my undergrad days, I am now in my 50s and fairly new to Arduino. The uint8_t and the uint32_t types reported in your compile errors are defined in the stdint. Hello. union { struct { uint8_t byte1; uint8_t byte2; uint8_t byte3; uint8_t byte4; }; uint32_t longint; } sample; AVR-GCC packs the struct LSB to MSB so byte4 would be [31:24] down to byte1 [7:0].
