# PSoC 6 Peripheral Driver Library v1.4.0

Please refer to the [README.md](./README.md) and the [PDL API Reference Manual](https://cypresssemiconductorco.github.io/psoc6pdl/pdl_api_reference_manual/html/index.html) for a complete description of the Peripheral Driver Library.

### New Features
* The structure of BSP startup templates directory (devices/templates) is updated to match the BSP layout.
* The updated core-lib is reused - see [SysLib changelog](https://cypresssemiconductorco.github.io/psoc6pdl/pdl_api_reference_manual/html/group__group__syslib.html) for details.
* Removed redundant legacy PSoC Creator-compatibility macros.
* The startup code reuses sysclk driver API - see [Startup changelog](https://cypresssemiconductorco.github.io/psoc6pdl/pdl_api_reference_manual/html/group__group__system__config.html) for details.

Updated Personalities
* CSD
* Power
* SegLCD
* WiFi
Updated the configurators launch parameters in CSD and SegLCD personalities: switched from GUI to console applications for regenerating the source code without opening the configurator itself. This improves the user experience, performance, and enables using machines without a GUI.
The Power personality code generation is corrected due to the customer's request.
The TCP Keepalive Offload feature support is added to the WiFi Low Power Assistant (LPA) personality.
