Hi Kenneth,
Is it the LED example that you commented at LinkedIn? It is important
to always explain exactly what you are trying to do and how you are
trying to do.
If you want add support for LEDs to be controlled by applications you need:
1) map the GPIO pins you are planing to use;
2) Create a boards/risc-v/k210/maix-bit/src/k210_userleds.c file.
It is not difficult, just use the
boards/arm/stm32/stm32f4discovery/src/stm32_userleds.c as reference
replacing the stm32_gpio* with k210_gpiohs_* ;
3) Modify the boards/risc-v/k210/maix-bit/src/Makefile with it:
ifeq ($(CONFIG_ARCH_LEDS),y)
CSRCS += k210_leds.c
else
CSRCS += k210_userleds.c
endif
4) Run "make menuconfig" and disable the usage of the LED for
diagnostic/boot status:
Board Selection --->
[ ] Board LED Status support
5) Yet in menuconfig enable the LED Driver support:
Device Drivers --->
LED Support --->
[*] LED driver
[*] Generic Lower Half LED Driver
6) Also enable the led application to see the "blinking LED show"
Application Configuration --->
Examples --->
[*] LED driver example
That's all folks!
BR,
Alan
