今日总算揣摩出来怎样在linux下烧录AT89s52.
下面是我的办法…当然可能有更好的办法.
这儿以Ubuntu为比方,先装置avrdude.
用下面的指令一次装全吧:
sudo apt-get install gcc-avr binutils-avr avrdude avr-libc
然后修改avrdude.conf:
sudo gedit /etc/avrdude.conf
在最终面参加AT89s52的相关信息(这是Joy Shukla写的)
#————————————————————
# Below chips by added by me .. Joy Shukla(joy_shukla@yahoo.in)
# these chips can be programmed with my usbasp programmer(changed atmega8 program)
# after adding avrdude support in this file ..
#————————————————————
#————————————————————
# AT89S52

part
id = “8052”;
desc = “AT89S52”;
signature = 0x1E 0x52 0x06;
chip_erase_delay = 20000;
pgm_enable = “1 0 1 0 1 1 0 0 0 1 0 1 0 0 1 1”,
“x x x x x x x x x x x x x x x x”;
chip_erase = “1 0 1 0 1 1 0 0 1 0 0 x x x x x”,
“x x x x x x x x x x x x x x x x”;
timeout = 200;
stabdelay = 100;
cmdexedelay = 25;
synchloops = 32;
bytedelay = 0;
pollindex = 3;
pollvalue = 0x53;
predelay = 1;
postdelay = 1;
pollmethod = 0;
memory “flash”
size = 8192;
paged = no;
min_write_delay = 4000;
max_write_delay = 9000;
readback_p1 = 0xff;
readback_p2 = 0xff;
read = ” 0 0 1 0 0 0 0 0″,
” x x x a12 a11 a10 a9 a8″,
” a7 a6 a5 a4 a3 a2 a1 a0″,
” o o o o o o o o”;
write = ” 0 1 0 0 0 0 0 0″,
” x x x a12 a11 a10 a9 a8″,
” a7 a6 a5 a4 a3 a2 a1 a0″,
” i i i i i i i i”;
mode = 0x21;
delay = 12;
;
memory “signature”
size = 3;
read = “0 0 1 0 1 0 0 0 x x x 0 0 0 a1 a0”,
“0 0 0 0 0 0 0 0 o o o o o o o o”;

然后保存
现在就能够烧录AT89S52的单片机了,
例如我想烧录放在桌面上的编译好的跑马灯程序,
用指令
sudo avrdude -p 8052 -c usbasp -e -U flash:w:/home/vowstar/桌面/跑马灯.hex
即可
作用如图:
开发板上的作用:
注意事项：
假如提示器材没有响应，signature = 0x000000原因是：usbasp的固件不能用原装的 （http://www.fischl.de/usbasp/）
要用来自这儿的http://www.8051projects.info/blogs/usb-8051-avr-programmer.html
2. 提示：~/Desktop $ sudo avrdude -p 8052 -c usbasp -e
avrdude: Cant find programmer id “usbasp”
Valid programmers are:
上面这种状况接 usbasp编程器(并口的)到电脑上,然后在终端下执行指令lsusb,提示：
~/Desktop $ lsusb
Bus 005 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub
Bus 004 Device 002: ID 16c0:05dc VOTI USBasp AVR Programmer

Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub
这样看来,编程器没问题能够被辨认.
查看一下/etc/avrdude.conf中是不是上文所述装备,然后查看编程器的跳线设置,跳线帽错没,再查看一下单片机是不是AT89S52,
最终承认单片机外围不能接其他影响IO传输的器材,比方DS18B20,ULN2003等,断开它们然后测验下载.
下载程序时要用root权限
