From 9c8b3225efd5ee816ad840ea97ba7bb92ff17941 Mon Sep 17 00:00:00 2001 From: Marti Bolivar Date: Tue, 24 Apr 2012 05:01:28 -0400 Subject: stm32.h: Various updates, mostly to help STM32F1 line support. Add STM32_HAVE_USB feature test macro requirement for . This will let us test if we've got a USB peripheral. wirish/stm32f1/boards_setup.cpp is set up to use this when turning on USB CDC ACM support at init() time. Rework the STM32F1 to make it easier to support the various lines that subdivide that series. We don't really support anything besides performance line yet, but there's been enough enthusiasm for value and connectivity line support in the past that these hooks seem worth adding. This means adding an STM32_F1_LINE macro and STM32_F1_LINE_[PERFORMANCE,VALUE,ACCESS,CONNECTIVITY] macros for values that STM32_F1_LINE can take, and generalizing the rest of the file to begin taking this into account. Some TODOs remain, but filling these in is the responsibility of future libmaple porting efforts. One pleasant consequence of the F1 stm32.h rework is that the build system no longer has to tell us what density of F103 we're building for, so remove that from the relevant support/make/board-includes/ files. Add some tweaks to and the STM32F2 stm32.h header to make sure this went through properly, and continues to go through properly in the future. --- libmaple/stm32f1/include/series/stm32.h | 100 ++++++++++++++++++++++---------- 1 file changed, 69 insertions(+), 31 deletions(-) (limited to 'libmaple/stm32f1') diff --git a/libmaple/stm32f1/include/series/stm32.h b/libmaple/stm32f1/include/series/stm32.h index c122df0..eaf9287 100644 --- a/libmaple/stm32f1/include/series/stm32.h +++ b/libmaple/stm32f1/include/series/stm32.h @@ -38,6 +38,17 @@ extern "C" { #define STM32_MCU_SERIES STM32_SERIES_F1 +/* The STM32F1 series is subdivided into "lines". libmaple currently + * officially supports STM32F103 performance line MCUs (see the + * MCU-specific value section below). + * + * You can use these F1 line defines if porting libmaple to support + * MCUs on other lines. */ +#define STM32_F1_LINE_PERFORMANCE 0 +#define STM32_F1_LINE_VALUE 1 +#define STM32_F1_LINE_ACCESS 2 +#define STM32_F1_LINE_CONNECTIVITY 3 + /* * MCU-specific values. * @@ -48,23 +59,31 @@ extern "C" { */ #if defined(MCU_STM32F103RB) +# define STM32_F1_LINE STM32_F1_LINE_PERFORMANCE # define STM32_NR_GPIO_PORTS 4 # define STM32_SRAM_END ((void*)0x20005000) +# define STM32_MEDIUM_DENSITY #elif defined(MCU_STM32F103ZE) +# define STM32_F1_LINE STM32_F1_LINE_PERFORMANCE # define STM32_NR_GPIO_PORTS 7 # define STM32_SRAM_END ((void*)0x20010000) +# define STM32_HIGH_DENSITY #elif defined(MCU_STM32F103CB) +# define STM32_F1_LINE STM32_F1_LINE_PERFORMANCE /* This STM32_NR_GPIO_PORTS is not strictly true, but only pins 0 * and exist, and they're used for OSC (e.g. on e.g. LeafLabs * Maple Mini), so we'll live with this for now. */ # define STM32_NR_GPIO_PORTS 3 # define STM32_SRAM_END ((void*)0x20005000) +# define STM32_MEDIUM_DENSITY #elif defined(MCU_STM32F103RE) +# define STM32_F1_LINE STM32_F1_LINE_PERFORMANCE # define STM32_NR_GPIO_PORTS 4 # define STM32_SRAM_END ((void*)0x20010000) +# define STM32_HIGH_DENSITY #else #error "Unrecognized STM32F1 MCU, or no MCU specified.
