AVR Option -H must not be defined more than once: -H1895 【已解决】-EEWORLD

Collect

When using IAR for AVR 5.40 to develop mega128, the following prompt appears during compilation

technology sharing

Cause Analysis:

-H was set once in the AVR compiler and also in the option file, causing a conflict.

The following options file content

/* Fill unused interrupt vector‘s with RETI */
-H1895
-h(CODE)0-_..X_INTVEC_SIZE

Solution

In general options, remove "Initialize unused interruupt vectors with RETI instruction", as follows

technology sharing

Keywords：AVR Option must not defined more than once: -H1895 Reference address：AVR Option -H must not be defined more than once: -H1895 【已解决】

Using AVR microcontroller to configure FPGA

Altera's ACEX, FLEX and other series of FPGA chips are widely used, but their FPGA is based on the SRAM structure, and the programming data that determines the logic function of the circuit is stored in the SRAM. Due to the volatility of SRAM, the programming data must be reloaded into the SRAM every time the power is

ICC AVR software Table key indents four spaces at a time

When using the ICCAVR C compiler, you will find that the indentation of the TAB key is not 4 spaces, which is a bit messy. Have you noticed that the TAB key in the ICCAVR software is abnormal and difficult to use? The TAB key is very useful when we align programs. We don't need to use spaces to align them manually.
