我用arm9 s3c2416系统，在linux下用QT设计开发软件，如何弄啊

ADS8332 + s3c2416

你的问题太泛太大了。难以回答

看到 msp430 + ads8332的定义如下

#define ADS8332_RESET      P1.7
#define ADS8332_EOC_INT  P1.6
#define ADS8332_CDI           P1.6
#define ADS8332_SCLK        P3.7
#define ADS8332_CS            P3.6
#define ADS8332_SDI           P3.5
#define ADS8332_SDO         P3.4
#define ADS8332_CONVST        P2.2     

#define ADS8332_RESET_1        P1OUT |= ADS8332_RESET
#define ADS8332_RESET_0        P1OUT &=~ADS8332_RESET

在arm9 linux 下如何配置呢？

PORT E CONTROL REGISTERS (GPECON, GPEDAT, GPEUDP, GPESEL)

Register Address R/W Description Reset Value

GPECON 0x56000040 R/W Configures the pins of port E 0x0

GPEDAT 0x56000044 R/W The data register for port E 0x0

GPEUDP 0x56000048 R/W Pull-up/down control register for port E 0x55555555

GPESEL 0x5600004c R/W Selects the function of port E 0x0

GPE13 [27:26] 00 = Input 01 = Output

10 = SPICLK0 11 = Reserved

GPE12 [25:24] 00 = Input 01 = Output

10 = SPIMOSI0 11 = Reserved

GPE11 [23:22] 00 = Input 01 = Output

10 = SPIMISO0 11 = Reserved

PORT G CONTROL REGISTERS (GPGCON, GPGDAT, GPGUDP)

If GPG0–GPG7 will be used for wake-up signals from Sleep/Stop/Deep Stop mode, the ports will be set in EINT.

Register Address R/W Description Reset Value

GPGCON 0x56000060 R/W Configures the pins of port G 0x0

GPGDAT 0x56000064 R/W The data register for port G 0x0

GPGUDP 0x56000068 R/W Pull-up/down control register for port G 0x55555555

GPG5 [11:10] 00 = Input 01 = Output

10 = EINT[13] 11 = Reserved

GPG4 [9:8] 00 = Input 01 = Output

10 = EINT[12] 11 = Reserved

GPG3 [7:6] 00 = Input 01 = Output

10 = EINT[11] 11 = Reserved

GPG2 [5:4] 00 = Input 01 = Output

10 = EINT[10] 11 = Reserved

GPG1 [3:2] 00 = Input 01 = Output

10 = EINT[9] 11 = Reserved

GPG0 [1:0] 00 = Input 01 = Output

10 = EINT[8] 11 = Reserved

我个人觉得这个应该问题需要拿到Processor相关的论坛下进行发帖提问。
