Hi there,

I'm trying to build an example rainmaker project (switch), but I encountered some errors.
Anyone encountered this? I'm using v4.0.1 on Windows 10.

Code: Untitled.bat Select all

C:/msys32/home/y.tan/esp/esp-rainmaker/components/led_strip/src/led_strip_rmt_ws2812.c: In function 'led_strip_new_rmt_ws2812':

C:/msys32/home/y.tan/esp/esp-rainmaker/components/led_strip/src/led_strip_rmt_ws2812.c:148:17: error: implicit declaration of function 'rmt_get_counter_clock'; did you mean 'rmt_get_source_clk'? [-Werror=implicit-function-declaration]

     STRIP_CHECK(rmt_get_counter_clock((rmt_channel_t)config->dev, &counter_clk_hz) == ESP_OK,

                 ^~~~~~~~~~~~~~~~~~~~~

C:/msys32/home/y.tan/esp/esp-rainmaker/components/led_strip/src/led_strip_rmt_ws2812.c:26:15: note: in definition of macro 'STRIP_CHECK'

         if (!(a))                                                                 \

               ^

Hello,

Please use the master branch of esp-idf. RainMaker uses some new code which isn't available on 4.0 or 4.1 releases/branches. We will add some "compatibility mode" config option soon to support these.

Piyush
