I liked your youtube video!
Then I tried a simple test with my CY8CKIT-044 and a pot.
I use same ADC configuration and moved the pot to in the middle.
And run my test program which basically do the same loop with your program
but meantime gather minimum adc value and maximum adc value for TEST_LOOP (=100)
and print the value to UART (TeraTerm).
Each line show the result of 100 loops, so I may be able to say that I could not observe the jump of value(s).
I'm afraid that probably the input voltage of your ADC is actually jumping.
Meantime, from my experience adding INJ pin and connect to VREF (pin1) usually gives me
better stability of ADC read values. But in this test case it did not affect much, since the original
condition is already stable with my hardware.
Attached is my test project.
Thanks, iIwill check.
What you mean "INJ pin and connect to VREF (pin1)" ?
VREF is internal voltage, i can't connect external pin to it..And into the creator can only uncheck the "enable" from INJ , Pin 1 is VSS
I'm sorry for confusing you.
At first I should have pointed you that in the Configure dialog of a component
we have Datasheet button which will open the Datasheet of the component.
So please refer to the Datasheet for the details of the component.
Meantime, since the previous message I have been thinking about
possible cause of the jump
(1) Sample mode
Since you are using ADC_StartConvert(), Free running Sample mode
may some times cause unstable data, how about using "Hardware trigger"?
(2) Result data format
Although you are specifying Unsigned, the result format for Single ended is "Signed."
So in case the result is negative, it surly show the jump between positive value
and negative value. How about display value with sign (+/-) or let's say in case
the result is negative make it 0 so that no negative value(s) will be displayed?
Thank you Motoo-san )
Now I check the sample project on the CY8CKIT-042 board, and il look work stable, so I will check my hardware and reading mode..
Just one thing are strange, how can it be that in one project I have 6 pins for connecting an ADC (green color box), and in another project there is only one pin on the same chip?
It's done, sorry for disturb..
The LCD pins are placed to the same port, dedicated for the analog input's, so I can't add other input)
