onde comprar aqui no brasil esse componente at89c51rc dip 40 pinos

[rebelk]

onde posso encontrar o arquivo at89c51rc.h , pois o meu keil uvision 2 não possui ou posso ultilizar outro equivalente?

eu fiz o download desses mas não tem o at89c51rc! alguem pode me ajudar?

compilo e gera esse erro

AS.C(981): error C202: 'TF2': undefined identifier
Target not created

no programa eu trabalho com o timer2 , mas ele não encontra os flegs
TR2 e TF2 ! dei uma verificado do arquivo REGF51RC.H e ele não é definido! help!!!!!!!!!!!!!!!!!!!!!!!!!!!

O da Phillips não seria equivalente? P89C51RC+IN

[rebelk]

consegui compilar sem problemas , acrescentei as definições do ( T2CON ) , agora estou tentando ultilizar algumas variaveis do meu programa na ERAM do micro ( at89c51rc ) , mas como faço para indicar o compilador a armazerar as variaveis na ERAM do micro?


ex ;

unsigned int xdata VALOR_DE_CORTE=0; // variavel alocada na eram
unsigned int idata CONTADOR=200; // variavel alocada na ram

VALOR_DE_CORTE=CONTADOR;

alguem poderia me dar um exemplo , uma dica pois estou perdido ,

sera que ninguem nunca alocou uma variavel na eram no 8051 e seus derivados , sera que ninguem vai me dar uma dica de como fazer isso , ou isso não é possivel . at89c51rc

[tcpipchip]

pq voce nao inclui no .H

sbit TR2 = 0x..
sbit TF2 = 0x..

Onde .. sao os endereços booleanos do 8052 ?

Olhe no data(ooo shit) do Atmel...lá tem os endereços

4. The 256-byte expanded RAM (ERAM, 00H-FFH) is
indirectly accessed by MOVX instructions, and with
the EXTRAM bit cleared.

The 256 bytes of ERAM can be accessed by indirect
addressing, with EXTRAM bit cleared and MOVX instruc-
tions. This part of memory is physically located on-chip,
logically occupying the first 256 bytes of external data
memory.
Figure 1. Internal and External Data Memory Address
(with EXTRAM = 0)
With EXTRAM = 0, the ERAM is indirectly addressed,
using the MOVX instruction in combination with any of the
registers R0, R1 of the selected bank or DPTR. An access
to ERAM will not affect ports P0, P2, P3.6 (WR), and P3.7
(RD). For example, with EXTRAM = 0,
MOVX@R0, # data
where R0 contains 0A0H, accesses the ERAM at address
0A0H rather than external memory. An access to external
data memory locations higher than FFH (i.e. 0100H to
FFFFH) will be performed with the MOVX DPTR instruc-
tions in the same way as in the standard MCS-51, i.e., with
P0 and P2 as data/address bus, and P3.6 and P3.7 as
write and read timing signals. Refer to Figure 1.
With EXTRAM = 1, MOVX @ Ri and MOVX@DPTR will be
similar to the standard MCS-51. MOVX@Ri will provide an
8-bit address multiplexed with data on Port 0 and any out-
put port pins can be used to output higher-order address
bits. This is to provide the external paging capability.
MOVX@DPTR will generate a 16-bit address. Port 2 out-
puts the high-order 8 address bits (the contents of DP0H),
while Port 0 multiplexes the low-order 8 address bits (the
contents of DP0L) with data. MOVX@Ri and
MOVX@DPTR will generate either read or write signals on
P3.6 (WR) and P3.7 (RD)
The stack pointer (SP) may be located anywhere in the 256
bytes RAM (lower and upper RAM) internal data memory.
The stack may not be located in the ERAM.
