Hi Guys, i am using STM8S003F3 controller and i want to know that how can i achive 0.1v accuracy or at least 1v accuracy.if my ADC resolution is 1023 and my total count is 2000 and Vref is 5v.
Is it possible to achieve it without changing in hardware ???????
Hiii, i am using internal adc of STM controller which is giving me offset voltage around 2v.
how can i reduce this error in C.is there specific way or some calculation.
Thanks!!
Hi,
my VDD is 5v.so i mapped it 0-2.5-5=1000-0-(-1000).
but i am facing two issue...
1. ADC channel generating continuous some randome value
2.step size error.
this error can be minimize by oversampling.but i dont understand how to get stable adc value??????????????
Actually i am measureing a voltage in both range positive as well as negaive.so,0-511 i will get negatibe value and 513-1000i get positive value.mean at 512 i will get 0v.
can you please elaborate more about set jumper n all..
Hiii guys, i am using stm8s003f3.i configure it according to datasheet and it work almost fine,but problem is, it is generating random voltage when there is no input is connected and because of this input fluctuation getting unwanted output.how to make this adc value zero if there are no input...
Hii... i am using STM8s003f3 controller,which have 10 bit ADC.
i am trying to measure +-1000v DC with 0.1 accuracy.
i know normally its not possible because of step size error,that is 1.955..
i want ask is there any way to achieve this goal without changing adc rsolution.
if there is any way...
but when i used other hex file on same hardware then it give me very smoot output.
i observe the output n i feel like there is some issue in reading adc value.coz some time it give output and some time it remain constant and some times it give very random output and again if used other hex...
hello...
i am using STM8s003f3 to read a voltages from channel 2.
but my readings are fluctuating. cann't understand the problems. i think i have done mistake in registors.
my adc is 10 bit and i am trting to measure +-200v. please guide .
i am quoting some part of code which is related to...
