## 1. Overview 演示普通的UART demo可以参考: https://youtu.be/_mwpw3nDrL8 使用LPUART_Flexio demo可以参考: https://youtu.be/VgoZpgZNC0A S32K344 LPUART的使用。低功耗通用异步收发器(Low Power Universal Asynchronous Receiver/Transmitter, LPUART)支持带有DMA 接口功能的基本UART,和x4 到x32 的过采样波特率,支持LIN 主从操作。该模块在Stop 和VLPS 模式提供的时钟保持启用时,仍可保持功能。         在S32K344 中有如下15个LPUART 模块: ## 2. 特性 ### 2.1...

# [S32K344] HSE Installation # 1. HSE固件bin文件下载 由于下载HSE是exe打包好的,你也可以从 https://github.com/carloscn/libs/tree/master/nxp/s32k344 下载,这里面包含了解压之后的所有HSE及HSE demo的源代码。也可以从官方渠道获取,如下: > Please downloaded from [S32K3 Standard Software](https://www.nxp.com/webapp/swlicensing/sso/downloadSoftware.sp?catid=SW32K3-STDSW-D&_gl=1*9ipxvx*_ga*MTQ4MzQ3NTIzNS4xNzE3MTIzMTQ5*_ga_WM5LE0KMSH*MTcyMjkwNjQ5Ni42Ni4wLjE3MjI5MDY1MDAuMC4wLjA.) > > Automotive SW - S32K3 - HSE Firmware >  S32K344 HSE...
