Hi,

RFX2401C芯片规格书中要求TXEN/RXEN外接1K电阻,如下图所示:

而CYBT-483056-02模块并没有这两个1k电阻,

请问CYW20719的程序是否需要wiced_hal_gpio_configure_pin()给芯片的P2, P4引脚配置上拉电阻?

针对这个模组,请在初始化的过程中加入下面的代码使能PA,不需要配置其他的GPIO:

(*((uint32_t *)0x338408)) = 0x48C;

(*((uint32_t *)0x338440)) = 0x47C;

(*((uint32_t *)0x338208)) = 0x600;

(*((uint32_t *)0x338240)) = 0x600;
