Please refer to the attached circuit and firmware files that design based on CC3220MOD chip.
The measured value of ADC PIN47 in our board is 0.7V, that’s not match our design, 1.5V. However 1.5V are measured in the PIN48, 49, and 50 as normal.
One issue that we guess, PIN47 also used be XDS_UART_TX in programming process cause PIN47 with wrong level.
Would you please help us check what’s the issue make the wrong level of PIN47?
Is there any unsuitable design in our circuit, or wrong coding in our firmware?
