Also i am waiting update official git, have any details about sync?

I turn back to the processing of ADC and came across a problem: after starting the firmware SDADCD3 falls (even without a halt).
With that SDARC1 works without problems.

Configuration: m

It fails if i uncomment adcSTM32Calibrate(&SDADCD3); or adcStartConversion(&SDADCD3, &sdadc3group, p_flow ...

Sorry i am forgot to say that adding icuStartCapture() fixes and now icu works as expected .

Ok, i enabled all debugging and found that i forgot to do icuStartCaptute() before icuEnableNotification().

Giovanny,

Found one bug in icu.h 183:

#define _icu_isr_invoke_width_cb(icup) do { \
if (((icup)->state == ICU_ACTIVE) && \
((icup)->config->period_cb != NULL)) \
(icup)->config->width_cb(icup); \
} while (0)


Checked wrong callback.

I added empty_handler for width_cb, but i still get 0 or 1 ...

Normal range is 1 Hz .. 1 kHz, but usually less than 300 Hz. Test signal ~10 Hz. Also hw has small RC-filter to eliminate noise.
A similar code worked with chibios 2.6, with same signal generator from blinking arduino .

I rewrote back to the callbacks, but there was another problem: icuGetPeriodX() returns only 0 or 1: 0 before the first event and 1 after.
Interrupts occur (updated last_update), but the value is not correct.

I have not used jtag debugging in this project, enough debug messages for me.
Here is the result:


(gdb) run
The program being debugged has been started already.
Start it from the beginning? (y or n) y

Hi all,

I want to use polled ICU, but when i try to use it immediatly halts (even without indication done in SYSTEM_HALT_HOOK).
By commenting-out i found that it breaks if i call icuWaitCompletion() or I-class in lock.
Also i tried do explicit icuDisableNotifications(), and fill callbacks with ...
