Aug 10, 2021 · Let's say I have a hex byte uint8_t my_hex = 0x50 that needs to be converted to its ASCII text equivalent which would be 'P'. I've tried using the Arduino library's built-in String object:

Feb 1, 2022 · Some notes: Using an array avoids the re-interpretation of a 32 bit variable as a byte array. You read bytes from SPI, and write() expects a byte array. This circumvents your endianness …

I want arduino send 1s and 0s to nodemcu as integer (e.g 0101) and I want nodemcu to read it as 0101 as normal everyday integer number. But instead it thinks that it is in a binary system (while it looks …

The binary value of 255 is a byte 11111111 or int 0000000011111111. I think that you can see the problem if you use byte data and the data is 255. So, if you receive an int -1, then you do not process …
