I just received MOD54415 and demo works fine.

Mod-Dev79 Rev1.7, MOD54415 Rev 1.5.

It is typically 10-15 uSec pulses and shortest is 1uS with delay between pulses up to 50mS.

Somehow I missed your question Paul. I'm using eTPU to generate single pulse, multiple pulses(<16) or continuous (PWM) outputs on 2 pins with shift between them. Mode is defined by command from remote system. Just not sure how PWM module of MOD54415 works yet, but I like the size and cost of Nano mo...

No. If you look on fs_etpu_qom_init() first thing it does it call fs_etpu_disable(channel).

TCR2 prescaler changes required for slow/long pulses of QOM or low frequency PWM. And in our test we use TCR1 anyway. I'm wondering why you should exclude QOM pins from default initalization. We know there is no eTPU related changes between 2.5.2 and 2.5.3. What other changes from vanilla nburn you ...

.s19 and APP.s19 files with exact code I posted before.

Sure. I will post it tomorrow morning (east time).

Your code work on my setup. Rel_2_5_2. Just in case I will copy everything: #include "predef.h" #include <stdio.h> #include <ctype.h> #include <startnet.h> #include <autoupdate.h> #include <dhcpclient.h> #include <smarttrap.h> #include <taskmon.h> #include <NetworkDebug.h> #include <etpu_u...

Good point Nixon. I forgot to mention it. And even switching between pure eTPU function doesn't always work. I know switching between PWM and QOM functions works, but between SPWM and QOM doesn't. And I don't use eTPUInit(), just MOD5234_etpu_init() and MOD5234_etpu_start() instead. Also, eTPU modul...

Well, for slow/long pulses you should switch to FS_ETPU_TCR2 timer. I also have to generate mS pulses on few other channels. And I can't remember exact values for frequency/dutycycle, but at some point I was actually forced to change prescaler for TCR2 to get it to work. My current settings: nburn_f...
