* stm32: Add Hardware PWM support for STM32G0 processors (#5714)Ben Jackson2022-09-013-4/+66
| | | | | | | | | | | Uses existing common code for STM32. Adds a table for device- specific PWM mappings. Adds support for enabling all TIM timer devices. Makes it a runtime error to enable devices the code doesn't know how to enable. I have verified performance of the fan pins (PC6, PC7, PB15) on the SKR Mini E3 V3.

* stm32: Use new CONFIG_USB to determine if USB needs to be configuredKevin O'Connor2022-08-165-12/+14
| | | | | | | | | | | | Introduce a CONFIG_USB build symbol that is set whenever CONFIG_USBSERIAL or CONFIG_USBCANBUS is set. Use that symbol during setup so that the USB controller is properly initialized for both usb serial and usb canbus bridge configurations. This fixes the clock configuration for usb canbus bridge mode on stm32f446. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>

* mcu: Delay reset signaling for usb to canbus bridge nodesKevin O'Connor2022-07-291-0/+3
| | | | | | | | An mcu device acting as an "mcu bridge" should only be reset after other normal devices are reset - otherwise the bridge wont be able to pass along the reset message to the downstream mcus. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* canserial: Request bootloader via bootloader_request()Kevin O'Connor2022-07-291-2/+1

* usb_cdc: Rename usb_request_bootloader() to bootloader_request()Kevin O'Connor2022-07-2914-32/+45

| | | | | | | | Move the uuid hash calculation to canbus.c and call canbus_set_uuid() from src/stm32/chipid.c . This simplifies the low-level canbus hardware code. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>

* canbus: Use single method for reading canbus messagesKevin O'Connor2022-06-164-198/+125
| | | | | | | | | | | | Previously the code had canbus_read() which was called from task context (for admin messages), and canbus_process_data() which was called from irq context (used for data messages). Change that to a single canbus_process_data() function that is called from irq context (used for all messages). This simplifies the low-level hardware specific canbus code and should make it easier to support other hardware implementations. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* canbus: Move global variables into a structKevin O'Connor2022-06-161-55/+65
| | | | | | | | Create a single CanData global variable to track the canbus state. ARM micro-controllers generally produce better code when global variables are in a struct. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>

* ds18b20: Allow some read errorsfunctionpointer2022-06-081-22/+33
| | | | | | | | | | | | | | | | | | | | | Allows a limited number of DS18B20 read failures before stopping the printer. This is designed to tolerate spurious read errors, while still stopping for serious issues. The printer will stop when the sensor fails to report a value five times in a row. Implementation works as follows: The MCU reports any read errors using a new "fault" parameter in its answers. The Python code tracks the number of errors and triggers the shutdown. This paves the way for more sophisticated error handling in the future, as well as an example for other sensors to follow. Signed-off-by: Lorenzo Pfeifer <Lorenzo.Pfeifer+github@googlemail.com>
