* stm32: Clear SPE flag on a change to SPI CR1 registerKevin O'Connor2022-02-101-0/+6
| | | | | | | | | The stm32 specs indicate that the SPE bit must be cleared before changing the CPHA or CPOL bits. Reported by @cbc02009 and @bigtreetech. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* stm32: Wait for transmission to complete before returning from spi_transfer()Kevin O'Connor2022-02-101-2/+5
| | | | | | | | | | | | | It's possible for the SCLK pin to still be updating even after the last byte of data has been read from the receive pin. (In particular in spi mode 0 and 1.) Exiting early from spi_transfer() in this case could result in the CS pin being raised before the final updates to SCLK pin. Add an additional wait at the end of spi_transfer() to avoid this issue.

* stm32: Unify enable_pclock() codeKevin O'Connor2021-12-308-238/+125
| | | | | | | | | Unify the handling of the enable_pclock() and is_enabled_pclock() code across all stm32 chips. All chips will now perform a peripheral reset on enable_pclock() (this is a change for stm32f0 and stm32h7). The enable_pclock() code will now also disable irqs during the enable.

* stm32: Rework register access on stm32f0_adc.cKevin O'Connor2021-12-231-34/+25
| | | | | | | | | | | Avoid read-modify-write operations where possible. The register values are in a known state so prefer absolute writes. Improve handling of race conditions with hardware updates. Remove the adc reference from "struct gpio_adc" as it is a constant. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>

| | | | | | | | Don't go above 400Mhz as otherwise it causes 32bit rollover issues. (Parts of the code expect a rollover will not occur faster than 10 seconds.) Signed-off-by: Kevin O'Connor <kevin@koconnor.net>

| | | | | | | | | | Add an optimized step function for drivers that support stepping on both rising and falling edges of the step pin. Enable this optimization on 32bit ARM micro-controllers. Automatically detect this capability in the host code and enable on TMC drivers running in SPI/UART mode. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* stm32: Remove gcc -mfpu=fpv4-sp-d16 floating point optionKevin O'Connor2021-10-301-1/+0
| | | | | | | | The floating point unit must be enabled in order to use it and Klipper does not currently implement that. Newer versions of gcc may spill registers to the floating point unit causing failures. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>

* stm32: Change stm32f0 OSPEEDR to "medium" speedKevin O'Connor2021-10-121-1/+1
| | | | | | | | | The previous OSPEEDR value of 0x2 was copied from the stm32f4.c code, but the stm32f0 interprets that value the same as 0x0 - which is "low" speed. Change the OSPEEDR value to "medium" speed so that it matches the configuration of stm32f1 chips. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>

* stm32: Adding Hardware PWM support for the STM32F4 processors (#4693)jrhelbert2021-10-112-1/+67
| | | | | This change has been expanded to include all STM32F4 processors, since they share a common TIMER mapping with some processors just not having all of the timers and pins. Signed-off-by: Jerome Helbert <jerome@helbert.net>
* config: Anycubic Vyper (#4740)Manuel Fichtner2021-10-111-1/+1
| | | | | | | | | | | This commit contains a configuration for the Anycubic Vyper printer from 2021. It uses a clone of the STM32F103 chip named GD32F103. There are 2 Mainboard versions out there v0.0.5 and v0.0.6, this config has been tested with the v0.0.6 only. It should probably work for v0.0.5 as well since there are no different changes in the Anycubic Marlin firmware. The LCD is not supported yet (might work, but didn't try yet).

| | | | | | | | | The F405, F407, and F429 chips are in the same series and almost all code definitions should apply to all chips in that series. Implement the alias and fix defintions in adc.c and Kconfig that were only applying to a subset of that series. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
