| * @author : Prabhakar kumar | ||
| * @email : prabhakar.kumar@alifsemi.com | ||
| * @version : V1.0.0 | ||
| * @date : 15-sept-2023 | ||
| * @brief : Testapp demo application code click board analog input | ||
| * - Internal input analog signal corresponding output is digital value. | ||
| * - the input from the Click Board (CLICK_ANA) is internally connected to | ||
| * the ADC121 instance channel_0(j11 Pin 8). | ||
| * - the converted digital value are stored in user provided memory | ||
| * address. | ||
| * | ||
| * Hardware Connection: | ||
| * Connect MIKROE Click board J29 and J30 for input. | ||
| * @note CLICK_ANA is then connected to the voltage level translator | ||
