# ESP-IDF SensorLib TouchDrv examples ```bash The current example only writes the CSTxxx series touch application. ``` ## Configure the Project Open the project configuration menu (`idf.py menuconfig`). In the `SensorLib Example Configuration` menu: * Select the communication method, will interface, callback interface, LL new version interface 1. Implemented using built-in read and write methods (Read and write methods are provided internally by SensorLib, supporting high version esp-idf >= 5.0, and low version methods (< 5.0)) 2. Implemented using read and write callback methods (Implemented using externally provided methods, suitable for multiple platforms) * In `Sensor SCL GPIO Num` select the clock pin to connect to the PMU,the default is 7 * In `Sensor SDA GPIO Num` select the data pin connected to the PMU,the default is 6 * Select the interrupt pin connected to the PMU in `Sensor Interrupt Pin`, the default is 8 * Select `Sensor reset Pin` , the default is 17 * `Master Frequency` The maximum communication frequency defaults to 100000HZ, and you can decide whether to change it according to the situation. ## How to Use Example Before project configuration and build, be sure to set the correct chip target using `idf.py set-target `. default use **esp32s3** ## Build and Flash Run `idf.py -p PORT flash monitor` to build, flash and monitor the project. (To exit the serial monitor, type ``Ctrl-]``.) See the [Getting Started Guide](https://docs.espressif.com/projects/esp-idf/en/latest/get-started/index.html) for full steps to configure and use ESP-IDF to build projects. ## Example Output The output information is to configure the output voltage and enable status of the PMU ```bash SPIWP:0xee mode:DIO, clock div:1 load:0x3fce2810,len:0x178c load:0x403c8700,len:0x4 load:0x403c8704,len:0xc10 load:0x403cb700,len:0x2dac entry 0x403c8904 I (26) boot: ESP-IDF v5.3-beta1-105-g3f632df143-dirt 2nd stage bootloader I (27) boot: compile time Jan 23 2025 16:49:34 I (27) boot: Multicore bootloader I (27) boot: chip revision: v0.2 I (27) boot.esp32s3: Boot SPI Speed : 80MHz I (28) boot.esp32s3: SPI Mode : DIO I (28) boot.esp32s3: SPI Flash Size : 2MB I (28) boot: Enabling RNG early entropy source...
