* 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: Add hardware PWM support for LPC176xMichael Kurz2021-03-265-0/+107
| | | | | | This adds hardware PWM support for LPC176x processors. Signed-off-by: Michael Kurz <michi.kurz@gmail.com>
* 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>

| | | | | | | | Writes over 496 bytes don't fit in a single "rpmsg" page. Request the host limit the number of bytes outstanding to avoid getting "write: (22)Invalid argument" errors. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>

* canbus: Move high-level CAN code to new src/generic/canbus.cKevin O'Connor2021-02-026-192/+323
| | | | | | | | | | Separate out the high-level command processing logic from the low-level transmission code. Place the high-level code in src/generic/canbus.c . This also removes the CAN dependency on serial_irq.c . Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* stm32: Simplify can.c irq handlerKevin O'Connor2021-02-021-127/+130
| | | | | | | Don't perform any heavy tasks in the CAN interrupt handler - just notify a background task to handle anything pending. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* stm32: Use CAN_TSR_CODE to select next tx fifo in can.cKevin O'Connor2021-02-021-6/+2
| | | | | | | | | | The spec states that the TX fifo is transmitted in chronological order if the TXFP bit is set, but it's unclear if the software needs to fill the tx fifo in a particular order to obtain that result. Use the TSR CODE bit field to fill the TX fifo in the order that the hardware reports as next. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
* stm32: Avoid read+write modify instructions in can.cKevin O'Connor2021-02-021-24/+13
| | | | | | | | | Prefer explicitly setting the hardware registers and avoid using C read and modify instructions where possible. This avoids race conditions where an interrupt or hardware change could cause subtle corruption of the register state. Signed-off-by: Kevin O'Connor <kevin@koconnor.net>
