I am making an oscilloscope using Cypress PSoC 3. The sample data is sent to the computer and plotted. The ADC is used in single ended configuration. Whenever I connect the signal generator to the board, it throws a lot of garbage values to the UART. On the signal generator, the amplitude set is 1Vpp with 1V dc offset at a frequency of 100Hz. The frame received looks something like this $18 18 18 18 18 18 18 18 18 18%. This problem did not occur when I tried connecting a DC power supply....
