Re: [Amforth-devel] 1284p compilation

[pito <pi...@vo...>]

With (template.asm based on Matthias):

; initial baud rate of terminal
.equ BAUD = 115200
.set USART_B_VALUE = (1<<TXEN0) | (1<<RXEN0)
.equ WANT_ISR_RX = 1;
.if WANT_ISR_RX == 1
.set USART_B_VALUE = (1<<TXEN0) | (1<<RXEN0)| (1<<RXCIE0)
.else
.set USART_B_VALUE = (1<<TXEN0) | (1<<RXEN0)
.endif
; 8N1 is commonly used
.equ USART_C_VALUE = (3<<UCSZ00)
.include "drivers/usart_0.asm"

the result of compilation is:

ATmega1284P memory use summary [bytes]:
Segment   Begin    End      Code   Data   Used    Size   Use%
---------------------------------------------------------------
[.cseg] 0x000000 0x01e7e2   1882   6134   8016  131072   6.1%
[.dseg] 0x000100 0x000100      0      0      0   16384   0.0%
[.eseg] 0x000000 0x00003e      0     62     62    4096   1.5%

Assembly complete, 0 errors. 0 warnings

I hope WANT_ISR_RX = 1 is what I want..
