From 59c4c498938f2c85c735034ed8f7b188725f07c9 Mon Sep 17 00:00:00 2001 From: Michael Kurz Date: Thu, 25 Mar 2021 20:39:53 +0100 Subject: stm32: Add hardware PWM support for STM32F1 This adds hardware PWM support for STM32F1 processors. This should also work for STM32 F0/F2/F4 processors, but I don't have one of those to test it.
