ADC_SAR error in PSoC Creator 2 & inaccuracy in ADC_DelSig
I am using the PSoC5 development kit, CY8CKIT-050, and face 2 issues.
1) I received the attached error "Component SAR could not be place because no more SAR blocks are available". However, I only use 1 ADC-SAR block in PSoC Creator 2, hence I don't understand why I cannot place the ADC_SAR block. Can anyone please advise?
2) Then I changed to use ADC_DelSig, but I found that the actual input voltage value is different from the measured output value. Eg. the input voltage is 1.893V, but the measured output value is 1.932V. There is an offset of about 0.03V. I am using a resolution of 16 for the ADC_DelSig. Can anyone advise how to reduce the offest? I have attached the program in this post.
Thanks & Regards
