My measurement result differ from expected value when the data transfer operation using USBUART takes place
Hi Cypress community,
I hve been working on a impedance meter project. I have a problem with the data transfer using the USBUART operation. Below is my program for the data transfer. I used teraterm as my COMport terminal. When i start the data transfer operation, my measurement result differ from the correct result. For instance, when testing a resistor, i observed 1k ohm at my LCD display which is a correct value, however, after i make connection to the COMport for the data transfer and start the operation, the value of the tested resistor become 500 ohm and even lower than that. This situation lead me to having a false measurement for the resistor value.
I hope this problem can be identify and solve.
Thanks in advance
