using internal DAC of a 16f1823

[Crenwick]

Hello,

In my new project I need to decode some bytes (with USART) and convert them to an anolog signal. I thought to use the 16f1823 because he has the USART and the DAC onboard.

But ! I'm unable to find how to use the DAC (located on RA0) with Flowcode...

Can someone give me an advice ?

Regards,

Bernard

Hello Bernard,

Not sure if this will work but looks simple enough.

Pop this code in via a C icon to setup the DAC.

Code: Select all

daccon0 = 0xE0;

To shift down a 8-bit ADC reading to 5-bit you would do this in a calculation icon.

Code: Select all

adc = adc >> 3

Then to control the voltage on the output you would do this where you have a Flowcode byte variable called adc.

Code: Select all

daccon1 = FCV_ADC;

Let me know how you get on.

Hi Ben,

Just test compiled in Flowcode and seems to work !

Now just waiting after my Chip

Thanks !
