Default Hypnos pins are incorrect for V3.3

[colinhalebrown]

Describe the bug The V2.5.1 of loom with the hypnos V3.3 board revision so default pins no longer work for sleep or for SD read and write.

Hardware in Use Feather M0 Hypnos V3.3

To Reproduce Set config settings to default then try reading or writing data to SD.

Expected behavior The SD card cannot be configured correctly.

Code ///////////////////////////////////////////////////////////////////////////////

// This is a basic example that demonstrates usage of the Hypnos board // Deep sleep functionality.

// The Hypnos board includes // - SD // - DS3231 RTC // - Ability to power of peripherals

// Further details about the Hypnos board can be found here: // https://github.com/OPEnSLab-OSU/OPEnS-Lab-Home/wiki/Hypnos

Config "{\ 'general':\ {\ 'name':'Device',\ 'instance':1,\ 'interval':5000,\ 'print_verbosity':2\ },\ 'components':[\ {\ 'name':'ADS1115',\ 'params':'default'\ },\ {\ 'name':'MAX31856',\ 'params':'default'\ },\ {\ 'name':'SD',\ 'params': 'default'\ },\ {\ 'name':'DS3231',\ 'params':'default'\ },\ {\ 'name':'Interrupt_Manager',\ 'params':[0]\ },\ {\ 'name':'Sleep_Manager',\ 'params':[true,false,1]\ }\ ]\ }"

Additional context Add any other context about the problem here.

[WL-Richards]

{\ 'name':'SD',\ 'params': [true, 1000, 11, "test", true]\ },\

Use that to set the chip select pin to 11 instead of 10 in the config

Same thing for pinMode(10, OUTPUT); this needs to be pinMode(11, OUTPUT); And pinMode(10, INPUT); needs to be pinMode(11, INPUT);

Please close this issue if the problem is fixed

Thanks, Will

Yeah we got it fixed a couple days ago just wanted to tell loom that the default had changed for future hypnos.
