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.

I2c non blocking

10

Replacement routines for I2c1_Rd and I2c1_Wr but here with timeout, so no blocking any more when a device one tries to access is not present. The mE I2c library is still needed for the remaining I2c routines. Implemented also the code for controllers with 2 I2c's (e.g. P18F27K40).

TFTP HTTP pic based file server for FAT32 sd/mmc cards

5

This is a small TFTP fileserver, using an mmc/sd card for file storage. "Small" means the software does not have an error/retry/timeout mechanism. Also file download via HTTP is implemented (URL = 192.168.123.90). This project uses the Ethernet libraries v3.5 by Yo2Lio.

Wifi Plus click HTTP Client

With this example one can load an internet page from an HTTP server. At this moment the remote IP address is fixed in the code and it loads the default file from the server. All data received from the HTTP server is sent to Uart1 where it can be picked up by a uart program to display or to save to a file.
