Bug in statistic RAM usage for 16F877 mikroc 6.62

[paulfjujo]

Hello,


in compiling window ,calculus seems correct for RAM and ROM usage
even the amount of RAM is based on 352 instead of 368 bytes for RAM..as specified in datasheet

i am using Windows 10 and MikroC pro 6.6.2

it is like some characters disappears from the screen
could you also show RAM amount in Bytes instead of Word.

Hello,

that is not a bug, PIC microcontrollers unfortunately use some amount of RAM memory for their system settings.

PIC microcontrollers unfortunately use some amount of RAM memory for their system settings.

PIC16F877 does not use any of the 368 bytes of GPR RAM for system settings. If there was a reason for omitting 16 bytes in Statistics, it could only be in attempt to exclude RAM that compiler uses for internal variables.

Anyway, the main problems pointed out by paulfjujo lay in unreadable RAM statistic - missing first digits or whole numbers and use of "program words" in reference to RAM registers that should be expressed in bytes.

Hello,

of course, syntax errors in the Statistics are the bug and they are already reported.
They should be fixed soon.

Thank you for your feedback.
