HarukiToreda d6f26c682d Enabling Ve pin on T114 (#4940) ... * Enabling Ve pin on T114 Problem: The Ve pin was not enabled in the firmware, and it was supposed to control the power to the GPS via the GPS_EN pin. As a result, users were forced to rely on the 3.3V pin to power their additional peripherals, which caused a constant power draw from the battery, even when the node was in deep sleep mode. Solution: To resolve this, Todd_Hervert and I decided to remove the GPS power toggle after testing revealed that the GPS only consumes 1mA in soft sleep mode. This minimal power consumption allowed us to enable the Ve pin without causing significant battery drain. Additionally, we added a delay to the I2C initialization process, as the Ve pin requires a few milliseconds to stabilize, which could prevent some peripherals from booting up in time. Result: The GPS operates as usual, drawing only 1mA of power. The keyboard and other peripherals attached to the Ve pin now power off correctly when the node is shut down. The I2C check initiates without issues after the delay, allowing all peripherals to function smoothly. * trunk format --------- Co-authored-by: Tom Fifield <tom@tomfifield.net>		2024-10-04 06:15:59 -05:00
