* stm32: Add support for STM32F1 I2C1 alternate pin mapping (#4012)Michael Kurz2021-03-021-4/+10
| | | | | | This adds support for the alternate pin mapping of I2C1 on PB8/9 in STM32F1 devices Signed-off-by: Michael Kurz <michi.kurz@gmail.com>
* stm32f1: Fix for using 16MHz external crystal (#3814)Matt Shepcar2021-01-241-2/+7

* stm32: Improved CAN support for STM32 (#2976)bondus2020-06-241-2/+29
| | | | | | | | | Reworked the STM32F0 CAN bus implementation. It's more robust and higher performance. Added support for function remapping to different pins. API is emulating an STM32F0. Improved and ported CAN bus to STM32F0, F1 and F4. Signed-off-by: Pontus Borg <glpontus@gmail.com>
* stm32f1: Add support for HID BootloaderArksine2020-05-281-3/+8

* stm32: Slow ADC frequency to 4.5MhzKevin O'Connor2020-04-301-1/+1
| | | | | | | There are reports that SKR mini boards have more stable ADC results when running the ADC at a slower frequency. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* stm32: Explicitly reset peripheral clocks on stm32f1Kevin O'Connor2020-03-241-0/+5
| | | | | | It appears some bootloaders do not properly reset some peripherals. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* stm32: Fix broken clock setup on stm32f1Kevin O'Connor2020-02-291-2/+2
| | | | | | | | | Commit bd6c25c9 introduced a typo that caused the clock divisors to not be set correctly on stm32f1. Reported by @brianrjones69. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* stm32: Allow external crystal speed to be customized in KconfigKevin O'Connor2019-11-251-10/+10

* stm32: Implement armcm_main() in arch specific codeKevin O'Connor2019-10-241-4/+16
| | | | | | | Move armcm_main() to stm32f0.c, stm32f1.c, and stm32f4.c. This gives the arch specific code more control on the early boot setup. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* stm32: Move VTOR fixup from main() to chip specific codeKevin O'Connor2019-09-181-0/+5

* stm32: Rename stm32f4/ directory to stm32/Kevin O'Connor2019-08-051-0/+125
Now that the code in stm32f4/ can handle both stm32f1 and stm32f4 chips, rename the directory to just "stm32". Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
