hi.! I'm beginning code android on kit S3C6410 as an example like ADC test on it, although i research datasheet carefully, i can get signal on port AIN0. I try with code in mini6410_adc.c to access port. #define ADCCON __ADCREG(S3C_ADCCON) // ADC control #define ADCTSC __ADCREG(S3C_ADCTSC) // ADC touch screen control #define ADCDLY __ADCREG(S3C_ADCDLY) // ADC start or Interval Delay #define ADCDAT0 __ADCREG(S3C_ADCDAT0) // ADC conversion data 0 #define ADCDAT1 __ADCREG(S3C_ADCDAT1) // ADC conversion data 1 #define ADCUPDN __ADCREG(S3C_ADCUPDN) // Stylus Up/Down interrupt status but it problem with library: #include <mach/map.h> #include <mach/regs-clock.h> #include <mach/regs-gpio.h> #include <plat/regs-timer.h> #include <plat/regs-adc.h> and other... I don't know how do it please help me.
help..! A/D Converter on AIN0 Android
hi Juergen Beisert, thanhks for your relay. i'm doing a mini application. It will receive analog from loadcell. And I make it work with AIN0 port,now. But i have problem, how i connect with my loadcell. maybe i must remove variable resistor on kit. And, now I try to build kernel driver to use other port (maybe AIN0), but I don't know how to build it. I try with Cygwin to use Linux. Do you know how do it?
Use the kernel from my BSP for the Mini6410. It gives you access to all available AD channels via sysfs. Refer http://www.friendlyarm.net/forum/topic/3015
