一、SDCC(Small Device C Compiler)编译环境搭建
SDCC是一个小型设备的C语言编译器,该编译器是标准C语言,可以编译Intel MCS51架构的微处理器,也可以编译STM8等常见MCU。我们要在linux上搭建51开发环境,首先要搭建SDCC编译环境。其主页是:
http://sdcc.sourceforge.net/ ,下面是SDCC的首页简介:
SDCC is a retargettable, optimizing Standard C (ANSI C89, ISO C99, ISO C11) compiler suite that targets the Intel MCS51 based microprocessors (8031, 8032, 8051, 8052, etc.), Maxim (formerly Dallas) DS80C390 variants, Freescale (formerly Motorola) HC08 based (hc08, s08), Zilog Z80 based MCUs (z80, z180, gbz80, Rabbit 2000/3000, Rabbit 3000A, TLCS-90) and STMicroelectronics STM8. Work is in progress on supporting the Microchip PIC16 and PIC18 targets. It can be retargeted for other microprocessors.
1.1、下载
有两个可供下载的:
注: 对于选择拿来即用的兄弟,可以直接跳过1.2节
1.2、编译
如何编译:
./config
可能会出现下面几种错误(我也给出了解决办法):
- 错误 1 、缺少bison :
configure: error: Cannot find required program bison.
解决方法: sudo apt-get install flex bison
- 错误 2 、找不到adjacency_list.hpp
configure: error: boost library not found (boost/graph/adjacency_list.hpp).
解决方法: sudo apt-get install libboost-date-time-dev libboost-program-options-dev libboost-system-dev libboost-filesystem-dev libboost-iostreams-dev
- 错误 3 、 没有PIC14、PIC16设备
failed for device/lib/pic14
解决方法: ./configure --disable-pic14-port --disable-pic16-port
1.3、测试
直接下载编译好的需要将其按照说明放入系统bin等文件中,采用编译的会自动将其放入系统bin中。而我比较喜欢不让其和系统的各种东西纠缠在一起,单独放在工程下的一个叫tool的文件里,大不了用的时候输全路径!如下,我在example目录下建一个makefile和a.c文件,将直接编译好的sdcc文件放在tool下面:
➜ SDCC_WS tree -L 2
.
├── example
│ ├── a.c
│ └── makefile
├── readme.md
└── tool
└── sdcc
其中a.c为51闪灯程序:
#include <8052.h>
void delay(void);
void main(void){
while(1){
P1 = 0xFF;
delay();
P1 = 0x00;
delay();
}
}
void delay(void){
int i,j;
for(i=0;i<0xff;i++)
for(j=0;j<0xff;j++);
}
makefile为:
SDCC_PATH=../tool/sdcc
z_sdcc=${SDCC_PATH}/bin/sdcc
z_packihx=${SDCC_PATH}/bin/packihx
a.hex:a.c
${z_sdcc} a.c
${z_packihx} a.ihx > a.hex
clean:
rm -rf *.asm *.lst *.mem *.rst *.lnk *.rel *.sym *.ihx *.hex *.map *.lk *.bin
二、Hex2Bin+命令行烧写工具配置使用
2.1、下载工具安装配置
理论上hex也能烧写,但是hex比bin要大一些,所以我们用这里用bin烧写。hex转bin要用到一个
Hex2Bin工具,将其下载下来解压到tool目录下;stc单片机烧写工具需要用一个github开源软件
stcflash,也将其下载到tool目录下:
➜ SDCC_WS tree -L 2
.
├── example
│ ├── a.c
│ └── makefile
├── readme.md
└── tool
├── Hex2bin-2.5
├── sdcc
├── software
└── stcflash
将makefile改为:
SDCC_PATH=../tool/sdcc
HEX2BIN_PATH=../tool/Hex2bin-2.5
STCFLASH=../tool/stcflash
z_sdcc=${SDCC_PATH}/bin/sdcc
z_packihx=${SDCC_PATH}/bin/packihx
z_hex2bin=${HEX2BIN_PATH}/hex2bin
z_stcflash=${STCFLASH}/stcflash.py
a.hex:a.c
${z_sdcc} a.c
${z_packihx} a.ihx > a.hex
${z_hex2bin} a.hex
clean:
rm -rf *.asm *.lst *.mem *.rst *.lnk *.rel *.sym *.ihx *.hex *.map *.lk *.bin
flash:
python ${z_stcflash} a.bin
2.2、编译+烧写
进入example目录运行make,自动编译:
输入make flash,给51单片机重新上电(冷启动)进行烧写:
