I migrate the program from Flowcode 8 to Flowcode 10 and I observed a strange behavior when the EEPROM has been written.
On my original code, I used EEPROM.Write() to save a byte of data.
On Flowcode 10 I observed the EEPROM.Write() may write 8 or 16-bits, so I changed to EEPROM.WriteByte(), but the EEPROM contents get worst.

I had some problem with the target migration from PIC16F18345 to PIC16F18444 that was fixed few days ago thanks to new library update.
I would like to know if my EEPROM problem is related, since the code was working for previous PIC.

Best regards,

Fernando

ADDITIONAL INFORMATION

The program runs the following block sequence:

Code: Select all

   Block:       EEPROM.WriteByte(0x0020, .0X01)
   Block:       EEPROM.WriteByte(0x0021, .0X03)
   Block:       EEPROM.WriteByte(0x0022, .0X01)
   Block:       EEPROM.WriteByte(0x0023, .0X01)

But the MPLAB shows the PIC16F18444 EEPROM as:

Code: Select all

   
   F020          00    00    00    00    00

It looks like the WriteByte() considers 0x01 as UINT, instead of byte, and saves the most significant byte.
