Hi All,
We are using nRF52840 MCU and SDK nRF5_SDK_for_Thread_and_Zigbee_v3.0.0_d310e71. We are designing a device that uses switches connected to the below pins,
Pin used are below,
1) ExtSW2 - P0.26
2) Learn - P0.17
3) Optional1 - P0.13
4) Optional 2 - P0.15
5) Up - P1.10
6) Down - P1.13
Regarding the above pins in the product specification document ie.,nRF52840_PS_v1.1 they are mentioned as GPIO pins. But in pca10056.h file,
P0.13 is mapped to" LED1",
P0.26 is mapped to "SPI Master In Slave Out GPIO pin number",
P1.15 is mapped to "SPI READY GPIO pin number" as well as "UART Clear To Send pin number. Not used if HWFC is set to false.", and
P0.02 is mapped to "SPI MOSI signal
I have checked the main.c file they are not used but to avoid any further issue while developing code can you tell me whether I can use these pins or not.
If yes, then how can I use these all pins in the main file without altering pca10056.h file. Because if I do any change in pca10056.h file my entire project file will affect.
Please let me know how to use these pins as per my requirement or will it affect anything to my project.
And also, can I use these below-mapped pins as per requirement? Or Do need to take care of any changes? If yes, then please let me know what all required changes to be done so that below all pins are assessable without altering pca10056.h file or without affecting this file.
