The Feather RP2040 USB Host is the TinyUSB reference board for PIO-USB host and does not require the CFG_TUSB_DEBUG workaround needed by the Waveshare (R13 pull-up issue). One host example is sufficient for the PR. The Feather variant has an improved display with splash, spinner, and 6-line live view. --- examples/host/CMakeLists.txt | 2 +- examples/host/midi2_host/CMakeLists.txt | 38 --- examples/host/midi2_host/Makefile | 27 -- examples/host/midi2_host/src/display.c | 221 -------------- examples/host/midi2_host/src/display.h | 54 ---- examples/host/midi2_host/src/font5x7.h | 107 ------- examples/host/midi2_host/src/main.c | 326 --------------------- examples/host/midi2_host/src/tusb_config.h | 91 ------ .../boards/waveshare_rp2350_usb_a/board.cmake | 2 - .../rp2040/boards/waveshare_rp2350_usb_a/board.h | 49 ---- 10 files changed, 1 insertion(+), 916 deletions(-) delete mode 100644 examples/host/midi2_host/CMakeLists.txt delete mode 100644 examples/host/midi2_host/Makefile delete mode 100644 examples/host/midi2_host/src/display.c delete mode 100644 examples/host/midi2_host/src/display.h delete mode 100644 examples/host/midi2_host/src/font5x7.h delete mode 100644 examples/host/midi2_host/src/main.c delete mode 100644 examples/host/midi2_host/src/tusb_config.h delete mode 100644 hw/bsp/rp2040/boards/waveshare_rp2350_usb_a/board.cmake delete mode 100644 hw/bsp/rp2040/boards/waveshare_rp2350_usb_a/board.h (limited to 'examples/host') diff --git a/examples/host/CMakeLists.txt b/examples/host/CMakeLists.txt index 7c74e3c73..2cf2c10af 100644 --- a/examples/host/CMakeLists.txt +++ b/examples/host/CMakeLists.txt @@ -13,7 +13,7 @@ set(EXAMPLE_LIST device_info hid_controller midi_rx - midi2_host + midi2_host_feather msc_file_explorer msc_file_explorer_freertos ) diff --git a/examples/host/midi2_host/CMakeLists.txt b/examples/host/midi2_host/CMakeLists.txt deleted file mode 100644 index cd70d122a..000000000 --- a/examples/host/midi2_host/CMakeLists.txt +++ /dev/null @@ -1,38 +0,0 @@ -cmake_minimum_required(VERSION 3.20) - -include(${CMAKE_CURRENT_SOURCE_DIR}/../../../hw/bsp/family_support.cmake) - -project(midi2_host C CXX ASM) - -family_initialize_project(${PROJECT_NAME} ${CMAKE_CURRENT_LIST_DIR}) - -# This example requires PIO-USB and Pico SDK (I2C, SSD1306 display) -if(NOT FAMILY STREQUAL "rp2040") - return() -endif() - -add_executable(${PROJECT_NAME}) - -target_sources(${PROJECT_NAME} PUBLIC - ${CMAKE_CURRENT_SOURCE_DIR}/src/main.c - ${CMAKE_CURRENT_SOURCE_DIR}/src/display.c -) - -target_include_directories(${PROJECT_NAME} PUBLIC - ${CMAKE_CURRENT_SOURCE_DIR}/src -) - -family_configure_host_example(${PROJECT_NAME} noos) - -# Waveshare RP2350-USB-A: PIO-USB on GP12/GP13 -target_compile_definitions(${PROJECT_NAME} PRIVATE - PIO_USB_DP_PIN_DEFAULT=12 -) -target_compile_options(${PROJECT_NAME} PRIVATE - -Wno-type-limits -) - -# SSD1306 display (I2C) -target_link_libraries(${PROJECT_NAME} PUBLIC - hardware_i2c -) diff --git a/examples/host/midi2_host/Makefile b/examples/host/midi2_host/Makefile deleted file mode 100644 index 2b4660516..000000000 --- a/examples/host/midi2_host/Makefile +++ /dev/null @@ -1,27 +0,0 @@ -# This example requires RP2040/RP2350 (PIO-USB, Pico SDK I2C, SSD1306 display) -ifeq (,$(findstring rp2040,$(FAMILY))) -$(info Skipping midi2_host: requires FAMILY=rp2040) -all: - @: -.DEFAULT: - @: -else - -include ../../../hw/bsp/family_support.mk - -INC += \ - src \ - -# Example source -EXAMPLE_SOURCE += \ - src/main.c \ - src/display.c \ - -SRC_C += $(addprefix $(EXAMPLE_PATH)/, $(EXAMPLE_SOURCE)) - -# Suppress pre-existing warning -CFLAGS_GCC += -Wno-type-limits - -include ../../../hw/bsp/family_rules.mk - -endif diff --git a/examples/host/midi2_host/src/display.c b/examples/host/midi2_host/src/display.c deleted file mode 100644 index 4745c2961..000000000 --- a/examples/host/midi2_host/src/display.c +++ /dev/null @@ -1,221 +0,0 @@ -/* - * The MIT License (MIT) - * - * Copyright (c) 2026 Saulo Verissimo - * - * Permission is hereby granted, free of charge, to any person obtaining a copy - * of this software and associated documentation files (the "Software"), to deal - * in the Software without restriction, including without limitation the rights - * to use, copy, modify, merge, publish, distribute, sublicense, and/or sell - * copies of the Software, and to permit persons to whom the Software is - * furnished to do so, subject to the following conditions: - * - * The above copyright notice and this permission notice shall be included in - * all copies or substantial portions of the Software. - * - * THE SOFTWARE IS PROVIDED "AS IS", WITHOUT WARRANTY OF ANY KIND, EXPRESS OR - * IMPLIED, INCLUDING BUT NOT LIMITED TO THE WARRANTIES OF MERCHANTABILITY, - * FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.
