* sht3x: reads should be retried with at least 0.5s pauseTimofey Titovets2025-07-112-3/+17
| | | | | | | | | | | | | SHT3x would return a read NACK on host retries. When the MCU receives the I2C CMD, it reads out data. SHT3x clears the data buffer. The MCU fails to deliver a response to the host. The host retries, the device returns NACK, then the MCU goes into the shutdown state. Make sure there is at least 0.5s between retries.

* stm32: f0 make i2c distinguish I2C NACKsTimofey Titovets2025-07-091-1/+11
| | | | | | | | | | Some devices can return a read NACK on host retries. When the MCU receives the I2C CMD, reads out data, but fails to deliver a response to the host. The host retries, the device returns NACK, and the MCU goes into the shutdown state. Signed-off-by: Timofey Titovets <nefelim4ag@gmail.com>
* ads1x1x: Rename local 'config' variable to pcfgKevin O'Connor2025-07-081-22/+22
| | | | | | | Avoid using the name "config" as a local register storage variable as it can be confused with the common "config" configfile reference. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* ads1x1x: Revert incorrect removal of assignment to self.configKevin O'Connor2025-07-081-0/+1
| | | | | | | | Commit d120a313b incorrectly removed an assignment to self.config - in this instance the reference was to a local variable not related to the global configfile storage. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>

* ar100: Convert to or1k-elf toolchainKevin O'Connor2025-06-083-12/+10
| | | | | | | | | The more.musl.cc site is blocking downloads from all github actions, which makes it difficult to use that site for the ar100 cross build toolchain. Convert to the openrisc or1k-elf toolchain as a replacement. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>

| | | | | | | | | | Update Code_Overview.md to note that the config object should not be stored after the "config loading phase". Remove a few inadvertent cases where a 'config' object was stored in module member variables. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>

| | | | | | | The rp2040 uses a pll vco divider of 6. Prefer setting postdiv1=6 and postdiv2=1 (instead of the previous postdiv1=3 and postdiv2=2). Signed-off-by: Kevin O'Connor <kevin@koconnor.net>

* docs: Update CAN bus command rate benchmarksKevin O'Connor2025-05-311-7/+12
| | | | | | | | | Add a benchmark for the rp2350 device when running via CAN bus. Remove the old stm32f042 CAN bus benchmark as that test predates a number of importnat CAN bus code changes and is likely no longer accurate. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>

* stm32: Simplify Kconfig HAVE_STM32_CANBUS checksKevin O'Connor2025-05-301-7/+7
| | | | | | | | | Avoid unnecessary (HAVE_STM32_CANBUS && MACH_STM32xx) checks in Kconfig. The HAVE_STM32_CANBUS is a helper symbol for all the chips that support canbus, there's no need to mix it with a check for a chip that is already known to have canbus.

| | | | | | | | | | Validate host provided index prior to accessing memory using that index. Also, consistently use a uint8_t for max_sections (to account for integer overflow issues). Signed-off-by: Kevin O'Connor <kevin@koconnor.net>

* sos_filter: Second Order Sections MCU FilterGareth Farrington2025-05-295-0/+407
| | | | | | | | | | This is an implementation of the SOS fliltering algorithm that runs on the MCU. The filter opperates on data in fixed point format to avoid use of the FPU as klipper does not support FPU usage. This host object handles duties of initalizing and resetting the filter so client dont have to declare their own commands for these opperations. Clients can select how many integer bits they want to use for both the filter coefficients and the filters output value. An arbitrary number of filter sections can be configured. Filters can be designed on the fly with the SciPy library or loaded from another source. Signed-off-by: Gareth Farrington <gareth@waves.ky>
