 		 #178245 - How to increase resolution
Responding to: ???'s previous message
Per Westermark said:
You can cover the range 0 to 2000mS/cm with 6 bits. Or with 8 bits. Or with 16 bits.

The range doesn't matter for the number of bits.

Is there any trick for that? where can i find any literature to learn it how.

My silabs MCU has 8bit PWM
all SILabs chips I know can do 16 bit PWM

Erik

Actually i am using the C8051F005. It has an 16 bit PCA that can be configure to be used in 8 bit PWM mode.
