From 3690af9bea5968653780d296146a91c63994d89d Mon Sep 17 00:00:00 2001 From: Dario Nieuwenhuis Date: Fri, 28 Jul 2023 15:29:27 +0200 Subject: [PATCH] stm32/timer: merge pwm module into timer. (#1703) The traits there are applicable to timer use cases other than PWM. It doesn't make sense to keep them separated. --- embassy-stm32/build.rs | 30 +- embassy-stm32/src/lib.rs | 1 - embassy-stm32/src/pwm/mod.rs | 269 ----------------- .../src/{pwm => timer}/complementary_pwm.rs | 0 embassy-stm32/src/timer/mod.rs | 271 ++++++++++++++++-- .../src/{pwm => timer}/simple_pwm.rs | 0 examples/stm32f4/src/bin/pwm.rs | 4 +- examples/stm32f4/src/bin/pwm_complementary.rs | 6 +- examples/stm32g4/src/bin/pwm.rs | 4 +- .../stm32h7/src/bin/low_level_timer_api.rs | 2 +- examples/stm32h7/src/bin/pwm.rs | 4 +- 11 files changed, 271 insertions(+), 320 deletions(-) delete mode 100644 embassy-stm32/src/pwm/mod.rs rename embassy-stm32/src/{pwm => timer}/complementary_pwm.rs (100%) rename embassy-stm32/src/{pwm => timer}/simple_pwm.rs (100%) diff --git a/embassy-stm32/build.rs b/embassy-stm32/build.rs index 0e9606ec..409a943d 100644 --- a/embassy-stm32/build.rs +++ b/embassy-stm32/build.rs @@ -572,21 +572,21 @@ fn main() { (("fmc", "Clk"), quote!(crate::fmc::ClkPin)), (("fmc", "BA0"), quote!(crate::fmc::BA0Pin)), (("fmc", "BA1"), quote!(crate::fmc::BA1Pin)), - (("timer", "CH1"), quote!(crate::pwm::Channel1Pin)), - (("timer", "CH1N"), quote!(crate::pwm::Channel1ComplementaryPin)), - (("timer", "CH2"), quote!(crate::pwm::Channel2Pin)), - (("timer", "CH2N"), quote!(crate::pwm::Channel2ComplementaryPin)), - (("timer", "CH3"), quote!(crate::pwm::Channel3Pin)), - (("timer", "CH3N"), quote!(crate::pwm::Channel3ComplementaryPin)), - (("timer", "CH4"), quote!(crate::pwm::Channel4Pin)), - (("timer", "CH4N"), quote!(crate::pwm::Channel4ComplementaryPin)), - (("timer", "ETR"), quote!(crate::pwm::ExternalTriggerPin)), - (("timer", "BKIN"), quote!(crate::pwm::BreakInputPin)), - (("timer", "BKIN_COMP1"), quote!(crate::pwm::BreakInputComparator1Pin)), - (("timer", "BKIN_COMP2"), quote!(crate::pwm::BreakInputComparator2Pin)), - (("timer", "BKIN2"), quote!(crate::pwm::BreakInput2Pin)), - (("timer", "BKIN2_COMP1"), quote!(crate::pwm::BreakInput2Comparator1Pin)), - (("timer", "BKIN2_COMP2"), quote!(crate::pwm::BreakInput2Comparator2Pin)), + (("timer", "CH1"), quote!(crate::timer::Channel1Pin)), + (("timer", "CH1N"), quote!(crate::timer::Channel1ComplementaryPin)), + (("timer", "CH2"), quote!(crate::timer::Channel2Pin)), + (("timer", "CH2N"), quote!(crate::timer::Channel2ComplementaryPin)), + (("timer", "CH3"), quote!(crate::timer::Channel3Pin)), + (("timer", "CH3N"), quote!(crate::timer::Channel3ComplementaryPin)), + (("timer", "CH4"), quote!(crate::timer::Channel4Pin)), + (("timer", "CH4N"), quote!(crate::timer::Channel4ComplementaryPin)), + (("timer", "ETR"), quote!(crate::timer::ExternalTriggerPin)), + (("timer", "BKIN"), quote!(crate::timer::BreakInputPin)), + (("timer", "BKIN_COMP1"), quote!(crate::timer::BreakInputComparator1Pin)), + (("timer", "BKIN_COMP2"), quote!(crate::timer::BreakInputComparator2Pin)), + (("timer", "BKIN2"), quote!(crate::timer::BreakInput2Pin)), + (("timer", "BKIN2_COMP1"), quote!(crate::timer::BreakInput2Comparator1Pin)), + (("timer", "BKIN2_COMP2"), quote!(crate::timer::BreakInput2Comparator2Pin)), (("sdmmc", "CK"), quote!(crate::sdmmc::CkPin)), (("sdmmc", "CMD"), quote!(crate::sdmmc::CmdPin)), (("sdmmc", "D0"), quote!(crate::sdmmc::D0Pin)), diff --git a/embassy-stm32/src/lib.rs b/embassy-stm32/src/lib.rs index ebd0e7cd..bb2ef2fc 100644 --- a/embassy-stm32/src/lib.rs +++ b/embassy-stm32/src/lib.rs @@ -43,7 +43,6 @@ pub mod flash;
