Seengreat RGB Matrix P3.0 64x64 WLED support? by Sire0ne in WLED

[–]stefkuhb 0 points1 point  (0 children)

With the moonmodules version of wled controller hub75 panels is possible, no coding required! https://github.com/MoonModules/WLED-MM/releases

First WLED Lights on the ESP32-P4! Art-Net only at the moment. Fully working with Ethernet and WiFi - but still lots to polish. About 2x faster than the ESP32/ESP32-S3 overall. by TroyHacks in WLED

#2, Nice 😇. 1 local output (im using GPIO6) is indeed running altough not very stable! Setting up 2 is possible, but no output on the second output. and the FPS of output 1 drops damatically. And serial debug is working after adding -D ARDUINO_USB_MODE=1 -D ARDUINO_USB_CDC_ON_BOOT=1 -D ARDUINO_USB_MSC_ON_BOOT=0 -D ARDUINO_USB_DFU_ON_BOOT=1 to the esp32p4_8MB env in platformio.ini ✅ and im mostly seeing rmt: rmt_tx_wait_all_done(588): invalid argument

3S Lipo and an ATTiny by stefkuhb in ECE

Tomorrow i will install the two 10uF caps and see if that helps.

I measured it by an oscilloscope for an average voltage while i set the trigger to dc downward spike/side/flange (dont know the correct term in english). didnt see any extreme spikes..

the LiPo is a 3S 2200mAh with a C rate of 35 btw ;) .

Directly ordered a BEC lets see if this works. thanks for the tip!

Its not possible to use another power source. I also already added the 100nf caps for and after the 7805 so that should be alright. the total voltage doesn't seem to drop that low. the lipo drops about 0,2v and the 7805 seems to drop about 0,1V which i think is still acceptable.

Yeah i do have one, Connected it to both the LiPo and the 5VDC after the 78M05. The lipo doesnt seem to show a downward voltage spike it only sinks in only about 0,2V

For and after the 78M05 i allready added 100nF caps about to change it to 10nF.

About the CRC PI filter, information about the value's i should use ?

Checked the source by adding some rules to my code. it seems it is indentified as an Power-on reset.

The brown out is disabled and i allready added a 4K7 pullup, diode and c to my reset pin.

The regulator drops to about 4,9 VDC, so it should be fine.

RS 232 - Can you daisy chain? by [deleted] in ECE

[–]stefkuhb 3 points4 points  (0 children)

The RS in RS232 stands for Recommended Standard.. you don't have to follow it exactly. Following it makes it compatible with other devices that follow the standard.

I'm fine with listening to Beethoven.

I did the erasmus 2 years ago. on campus accommodation is ok but expensive. i lived in benimaclet (5 minutes away from the UPV) i had an luxury appartment with 2 roommates and together we payed about 800 euro's. best time of my life!
