A while ago I ran into a problem related to variable alignment. I tried to read in the data of a record transmitted via Uart by a PIC18 into a PIC32. It went wrong because the internal structure of the record was different between the two PIC families.

Apparently also inside a variable alignment is taken into account.

In this article some observations and possible problems regarding this issue.

2021-06-13: Added another example: the Bootinfo used by the mE bootloaders to send information about the PIC to the PC USB HID bootloader tool.

The basic functions for the DS18(S/B)20 (onewire digital temperature sensor), including string output, ready to display. A routine to convert a more than 9 bits temperature read from a DS18B20 to a string (to e.g. display on an LCD) is also present. Including Parasite Power and Configuration routines. The LM35 basic functions, code efficient.

Libaries are:
- "MemManager_": simple memory manager making dynamic variables possible in mP (procedures GetMem and FreeMem available), and
- "Eepromvariable": Procedures/functions that write and read the content of any type of variable to/from the internal PIC Eeprom.
