Posted on December 18, 2017 at 21:20hi.
i wrote a code for ADC1 , and i could get value from ADC1_channel_1 (IN1) but i cant get value of Channel_2 and show both of two value on LCD in same time.
I dont know which function can I use to get both value . in this code i have just Channel_1 value .
i use IAR and stm32f103RE.
(i know the code is long , but i sholud put it for you , so thanks)
&sharpinclude 'stm32f10x.h'
&sharpinclude 'stm32f10x_gpio.h' // for Enable LCD
&sharpinclude 'stm32f10x_rcc.h' //for Enable LCD
&sharpinclude 'stm32f10x_adc.h'
&sharpinclude 'LCDLib.h'
&sharpinclude 'delay.h'
