* debugcmds: Remove start/end_group commandsKevin O'Connor2021-05-071-38/+2
| | | | | | | | These commands were never used by the main code and are not particularly helpful for debugging. Remove them to reduce code size - in particular on the pru architecture. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* stm32: Enable ADC3 pins on stm32f446Kevin O'Connor2021-05-061-2/+2
| | | | | | Reported by @bigtreetech. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* lpc176x: Use full peripheral clock speed; fix UART interfaceKevin O'Connor2021-05-041-1/+1
| | | | | | | | | | | Commit ae89a659 caused a regression in the lpc176x UART handling. After that commit the UART clock divisor would need to be 6.25 on lpc1768 or 7.5 on lpc1769, but the code only supports whole numbers. Set the PCLKSELx registers at startup and return to using full speed peripheral clocks. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>

* stepper: Remove min_stop_interval from mcu codeKevin O'Connor2021-04-301-13/+3
| | | | | | | Now that the host never uses a min_stop_interval, remove it from the mcu code. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>

* linux: Don't use timer_repeat_until for linux "irq" pollingKevin O'Connor2021-04-211-29/+9
| | | | | | Use a simpler counter system to prioritize tasks and irqs when busy. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* sched: Call irq_poll() at start of run_tasks() loopKevin O'Connor2021-04-211-0/+1
| | | | | | | On architectures that poll for irqs, check for any pending irqs prior to checking if tasks are idle. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* linux: Rework timer_check_periodic() to use ticksKevin O'Connor2021-04-193-14/+14
| | | | | | Avoid using a 'struct timespec' to simplify the code. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* linux: Move timer fields into a structKevin O'Connor2021-04-191-31/+37
| | | | | | Storing the fields in a struct allows gcc to optimize memory pointers. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* linux: Avoid calling timer_read_time() in timer_dispatch() when not neededKevin O'Connor2021-04-181-3/+15
| | | | | | | The timer_read_time() call can be expensive - when the next timer is definitely pending, avoid making that call. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* linux: Simplify timer dispatch codeKevin O'Connor2021-04-181-54/+50
| | | | | | | | Implement rescheduling math using the simple 32-bit timer instead of the Unix timespec struct. This makes the code simpler and doesn't adversely impact the overall performance. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* linux: Fix local timer_repeat_until cache in timer.cKevin O'Connor2021-04-181-1/+1

* stm32f1: reset peripherals in enable_pcclock()Arksine2021-04-071-0/+4
| | | | | | Some bootloaders do not disable peripherals in use before jumping to the application. Reset peripherals to assure correct operation. SIgned-off-by: Eric Callahan <arksine.code@gmail.com>
* stm32: Add hardware PWM support for STM32F1Michael Kurz2021-03-265-0/+179
| | | | | | | | | 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. Signed-off-by: Michael Kurz <michi.kurz@gmail.com> Signed-off-by: Kevin O'Connor <kevin@koconnor.net>

* lpc176x: Do not modify PCLKSELx at runtimeKevin O'Connor2021-03-251-8/+1
| | | | | | | | | The lpc176x has an errata that could cause updates to PCLKSELx to not take effect. Rework the code to use the default peripheral clock speed (25Mhz or 30Mhz) so that this register does not need to be updated at runtime. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* lpc176x: Introduce get_pclock_frequency()Kevin O'Connor2021-03-256-12/+23

| | | | | | 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>
* fan: Add tachometer supportAdrian Keet2021-03-012-1/+100
| | | | | | | | | | | | | | This adds new config options for fans: 'tachometer_pin' to specify the GPIO pin, and 'tachometer_ppr' (default 2) to specify the number of signal pulses per revolution. The rpm is also exposed by get_status for command templates and the API server. For fast fans (at least 10000 RPM), the polling interval can be shortened using the 'tachometer_poll_interval' option. There is a new mcu object for a generic edge counter, which repeatedly polls a GPIO pin and periodically reports the count to the host. Signed-off-by: Adrian Keet <arkeet@gmail.com>
