ChibiOS Free Embedded RTOS

Hi,

That's what I'm using
(sorry for the delay, these times, I'm not actively reading the forum)

I'm using standard halconf/mcuconf for the STM32F042K6 with PWM enabled

// PWM
static const PWMConfig pwm_cfg = {
.frequency = 1000000, /* 1MHz PWM clock frequency. */
.period = 250 ...

Hi

According to the datasheet, it seems possible to use TIM14 CH1 as a PWM, but I don't see support for TIM14 in the hal pwm code.

Is there some restrictions?

Thanks

Hi.

You need to use ruby 2.3, due to the &. syntax and some of the Enumerable methods

Volume is currently not handled by the driver as it is not possible to control it by using only the pwm driver.
It would requires additional circuitry to control it using the voltage. If you can provide me with ...

I've written a small code to allow basic control of a buzzer and to play "melody" (using a compact format)

I'm putting the link here, if it can be useful to someone else.

Also it would be very convenient if it was possible to extend the info command with new information, perhaps something like

shell_cmd.h

#if defined(SHELL_CMD_INFO_EXTRA)
SHELL_CMD_INFO_EXTRA(BaseSequentialStream *chp, int argc, char *argv[]);
#endif


shell_cmd.c

static void cmd_info ...

Hi

It would be nice to have the "info" command listing the hal drivers that have been compiled in, something like:


chprintf(chp, "HAL drivers: %s"SHELL_NEWLINE_STR,
""
#if defined(HAL_USE_RTC) && HAL_USE_RTC
" RTC"
#endif
#if defined(HAL_USE_PAL) && HAL_USE_PAL
" PAL"
#endif

I'm working on nrf52 port, I've got one test case failing with "out of time window" (3.2)

Test is starting at time 3337ms, ending at 4337ms, which seems to "nearly" meet the 1000 ms timeout requirerment of the test.
Test is using

test_assert_time_window(time + MS2ST(1000),
time + MS2ST(1000 ...

I'm no expert at embedded system, so when I wrote my little code I googled a lot, and found this docummentation about debouncing:
m
At page 6, it seemed to me that using an interrupt was not a good idea, and I went for the easy way of a virtual timer kicking at fixed interval.

The ASCII / keyboard ...

Having an abstraction of a general user-input system would be great. I'm not feeling doing it by myself, but would be happy to help.

Hi,

(I'm not sure if it is the right forum section to post)
I've started to write a component for handling switch/button, so to avoid having to write the same code every time.
It is handling debouncing, grouping 2 buttons to emulate a third one, and optionally generate dbl-click and longpress ...
