16 bit a/d support

[J_norrie]

I have just purchased PicBasicPro and would like to use it in a project I am about to start. I have most of the code already written in asm for the Pic16C57 which I eventually managed to convert to the 16F57. I would like to know if anyone has used the pic16F877A with a 16 Bit ADC Convertor (2 channels preferred). The 10 bit ADC on the pic16f877a is not ghood enough.

thanks in advance John

Hi,

You have not mentioned the ADC chip you would be using.

hi sougata, I dont have any particular in mind, except that the sample rate is better than 50 sps for two channels and it is a DIP package. The input voltage can be anything between 0-10mV to 0-10vdc. I was looking at the possibly of using the AD7705. It has to be readily available.
thanks again John

Hi,

A quick glance at the datasheet seems it to be a good choice considering the onboard PGA. However for larger input signals you may need to use input attenuation. Serial interface is easy to handle in PBP too.

Best of Luck.
