Their friend , I was a Pxx16fxxxx user before have been met with lpc...
That is amazing mcu and ı have started to proramme it .
I know my english going to make you mad )) but I could not find any information in my own ,I am preparing usermanual about LPC in my own language so need your helps...
Furtheremore I could not find where is that Vref pin, how can we supply Vref? or is it standart 3.3V?
In order to read LM35 , I have to calculate Voltage and this adc is 12 bit and everythings depends on Vref...
if is it standart 3.3 vo then 111111111111=3.3V and 000000000000=0v in case it is 3.3V and 1 step responds 0.805 mV,on the other hand can I supply it with different voltages for ex 5V then
111111111111=5 and 000000000000=0 :)
or 000000000001=1.22 mV
so when adc generate 00001111111111= 1.22mV*1024 = 1.249 V in case Vref=5V..
is any adc experienced or trained friend here?Tell me how did you do it ))
I have problem with hardware :(
