From d7173967087e022d20d1f9c812b1b668e9d3f71b Mon Sep 17 00:00:00 2001 From: Stefan Kerkmann Date: Thu, 30 Jun 2022 13:19:27 +0200 Subject: [Core] Add Raspberry Pi RP2040 support (#14877) * Disable RESET keycode because of naming conflicts * Add Pico SDK as submodule * Add RP2040 build support to QMK * Adjust USB endpoint structs for RP2040 * Add RP2040 bootloader and double-tap reset routine * Add generic and pro micro RP2040 boards * Add RP2040 onekey keyboard * Add WS2812 PIO DMA enabled driver and documentation Supports regular and open-drain output configuration. RP2040 GPIOs are sadly not 5V tolerant, so this is a bit use-less or needs extra hardware or you take the risk to fry your hardware. * Adjust SIO Driver for RP2040 * Adjust I2C Driver for RP2040 * Adjust SPI Driver for RP2040 * Add PIO serial driver and documentation * Add general RP2040 documentation * Apply suggestions from code review Co-authored-by: Nick Brassel Co-authored-by: Nick Brassel --- platforms/chibios/vendors/RP/RP2040.mk | 285 +++++++++++++++++++++++++++++++++ 1 file changed, 285 insertions(+) create mode 100644 platforms/chibios/vendors/RP/RP2040.mk (limited to 'platforms/chibios/vendors/RP/RP2040.mk') diff --git a/platforms/chibios/vendors/RP/RP2040.mk b/platforms/chibios/vendors/RP/RP2040.mk new file mode 100644 index 0000000000..1aa925cb15 --- /dev/null +++ b/platforms/chibios/vendors/RP/RP2040.mk @@ -0,0 +1,285 @@ +# +# Raspberry Pi RP2040 specific drivers +############################################################################## +COMMON_VPATH += $(PLATFORM_PATH)/$(PLATFORM_KEY)/$(DRIVER_DIR)/vendor/$(MCU_FAMILY)/$(MCU_SERIES) + +ifeq ($(strip $(WS2812_DRIVER)), vendor) + OPT_DEFS += -DRP_DMA_REQUIRED=TRUE +endif + +# +# Raspberry Pi Pico SDK Support +############################################################################## +ADEFS += -DCRT0_VTOR_INIT=1 \ + -DCRT0_EXTRA_CORES_NUMBER=0 + +CFLAGS += -DPICO_NO_FPGA_CHECK \ + -DNDEBUG + +# +# Pico SDK source and header files needed by QMK and ChibiOS +############################################################################## +PICOSDKROOT := $(TOP_DIR)/lib/pico-sdk + +PICOSDKSRC = $(PICOSDKROOT)/src/rp2_common/hardware_clocks/clocks.c \ + $(PICOSDKROOT)/src/rp2_common/hardware_pll/pll.c \ + $(PICOSDKROOT)/src/rp2_common/hardware_pio/pio.c \ + $(PICOSDKROOT)/src/rp2_common/hardware_gpio/gpio.c \ + $(PICOSDKROOT)/src/rp2_common/hardware_claim/claim.c \ + $(PICOSDKROOT)/src/rp2_common/hardware_watchdog/watchdog.c \ + $(PICOSDKROOT)/src/rp2_common/hardware_xosc/xosc.c \ + $(PICOSDKROOT)/src/rp2_common/pico_bootrom/bootrom.c + +PICOSDKINC = $(CHIBIOS)//os/various/pico_bindings/dumb/include \ + $(PICOSDKROOT)/src/common/pico_base/include \ + $(PICOSDKROOT)/src/rp2_common/pico_platform/include \ + $(PICOSDKROOT)/src/rp2_common/hardware_base/include \ + $(PICOSDKROOT)/src/rp2_common/hardware_clocks/include \ + $(PICOSDKROOT)/src/rp2_common/hardware_claim/include \ + $(PICOSDKROOT)/src/rp2_common/hardware_gpio/include \ + $(PICOSDKROOT)/src/rp2_common/hardware_irq/include \ + $(PICOSDKROOT)/src/rp2_common/hardware_pll/include \ + $(PICOSDKROOT)/src/rp2_common/hardware_pio/include \ + $(PICOSDKROOT)/src/rp2_common/hardware_sync/include \ + $(PICOSDKROOT)/src/rp2_common/hardware_resets/include \ + $(PICOSDKROOT)/src/rp2_common/hardware_watchdog/include \ + $(PICOSDKROOT)/src/rp2_common/hardware_xosc/include \ + $(PICOSDKROOT)/src/rp2040/hardware_regs/include \ + $(PICOSDKROOT)/src/rp2040/hardware_structs/include \ + $(PICOSDKROOT)/src/boards/include \ + $(PICOSDKROOT)/src/rp2_common/pico_bootrom/include + +PLATFORM_SRC += $(PICOSDKSRC) +EXTRAINCDIRS += $(PICOSDKINC) + +PLATFORM_RP2040_PATH := $(PLATFORM_PATH)/$(PLATFORM_KEY)/vendors/$(MCU_FAMILY) + +PLATFORM_SRC += $(PLATFORM_RP2040_PATH)/stage2_bootloaders.c \ + $(PLATFORM_RP2040_PATH)/pico_sdk_shims.c + +EXTRAINCDIRS += $(PLATFORM_RP2040_PATH) + +# +# RP2040 optimized compiler intrinsics +############################################################################## + +# Enables optimized Compiler intrinsics which are located in the RP2040 +# bootrom.
