收到板卡有段时间了,现在来开个箱,顺便搭建一下开发环境。
该板由一个MCXN947器件和一个64 mbit外部串行闪存(由Windows提供)组成。
2.该板还具有P3T1755DPI3C温度传感器,CAN PHY,以太网PHY,SDHC电路(DNP),RGB LED,触摸板,高速USB电路,按钮和MCU-Link调试探头电路。
提供Arduino扩展,PMOD扩展,MicroBus总线扩展。
支持摄像头模块和NXP低成本LCD模块PAR-LCD-S035。
兼容Arduino屏蔽模块和Mikroe点击板。
板载MCU-Link调试探头基于LPC55S69单片机。
先用MDK配合JLINK来烧录个测试程序。使用的例程是:
SDK_2_14_0_FRDM-MCXN947\boards\frdmmcxn947\driver_examples\gpio\led_output\cm33_core0
编译正常。
