Subject: [PATCH] [GS] Added GS bsp
BSP: Added the bsp with the hwmapping for the new GS and the bsp.cpp updated.
Make: Updated the boards.cmake with the new BSP
c_cpp_properties: Added the properties for the new GS board
WIP: bsp_impl.h is still in WIP
[GS] Formatting fix
[GS] Fixed pipeline.
Fixed pipeline: Wrong boardname was set on board_options, c_cpp_properties.
Also an #endif in hwmapping.h from old code now removed.
[BSP] Updated BSP: bsp_impl and hwmapping
bsp_impl: Added the sd and ram functions
hwmapping: Fixed the names in the dip switch namespace, added pins for remote controller (TLC) for ARP
[BSP] Updated bsp_impl, missing I/O and radio pin initialization
Some pin initialization was missing (Radio, TLC, dipSwitch)
[BSP] GS BSP update: Remote command box arm/disarm and leds
hwmapping: Added LEDs (Compute unit), command box arm/disarm switch.
bsp/bsp_impl: Led functions and initialization
[BSP] GS BSP fix ledOn, commandbox leds
bsp_impl: Fixed ledOn userLedx typo.
hwmapping: Added into the namespace the leds-timers mapping of the commandbox.
[BSP] GS bsp fixes
Fixes about the namespaces used, switchArm/Disarm in bsp.cpp, ifdef in hwmapping.h, also commandBox now outside interfaces namespace.
[BSP] GS bsp changed on top of the Compute unit v2 ones
The BSP was based on the old gemini gs instead of the compute unit v2 ones.
Now changed to those configurations and hw implementations with the mapping of the lyra gs.
[BSP] Automated_antennas BSP txen, rxen alias for the radio
Added txen and rxen namespace alias
[BSP] Added stepper pins initialization
Stepper pins initialization was missing from the BSP
[BSP] Minor reorder of the stepper enable in bsp.cpp
[BSP] GS: Removed CAN1
Removed CAN1 since no integral chip on the board for CAN
[BSP] GS Led naming
Changed led naming since color have changed
[BSP] GS BSP fixed switchActive was signed as switchDisarm
The active switch of the command box was incorrectly signed as switchDisarm, now correctly switchActive
[BSP] GS BSP now using leds as pins and not timers
Using now leds of the command box as pin and not timers, since using a thread for its control.
[BSP] Led bsp update for commandBox
[BSP] GS Fix on enable and disable pin of the steppers
The enable and disable pins was switched. Now fixed
[BSP] USART2 rx to pull up open drain and tx pull up for VN300
Fix: RX to pull up open drain since there are issues without the VN300 with the IDLE register.
[BSP] SD one bit data bus and divider
Was missing flag for one bit data bus SD and divider for maximum frequency
