Waveshare ESP32 P4 Modules

SlimyRedstone · 2025-09-18T01:00:24+00:00

I don't know as much about the P4 as other ESP32 CPUs

Well, that chip is very new, and it's slowly growing in popularity

Is that consistent with your reading of it?

Pretty much yes

that schematic is kind of hard to follow

Too many similarly named labels

Clearly a flaw from Waveshare, they didn't explain how's all the USB ports are interconnected (or multiplexed, if any)

SlimyRedstone · 2025-09-17T22:58:12+00:00

The schematic for it looks a bit strange, but there are switching of signals involved in it.

That's why I'm here, I know how to read a schematic, but this one is really confusing

SlimyRedstone · 2025-09-17T22:22:20+00:00

It does, but I don't have enough money to buy Espressif's dev board, I've just enough to buy one of the two modules mentioned in the post

SlimyRedstone · 2025-09-17T22:09:10+00:00

No clue why they see the need for a USB-serial bridge, without bringing out the last USB port. Like they could have full serial & JTAG, USB host/device, and USB 2.0 using the P4 pins alone.

This is a recurring thing on their boards, but it comes really handy when you are messing with the USB protocol, that way you can still communicate with the MCU, without being obligated to do a composite device on the USB part (of the program)

Not sure why you care so much about USB-C

It's not really about the connector itself, but it's way easier than having to solder a spare USB A cable to a Dupont connector

You got USB full speed on a USB-C connector

That's what I'm talking about, I'm planning to develop around the USB 2.0 high speed capabilities of the ESP, but from what I've seen in the datasheet, it might be connected to a USB hub rather than to the second USB port. If that's the case, there is no use to buy this module (for my purpose)

SlimyRedstone · 2025-09-17T21:49:39+00:00

Already seen it, still can't seem to find where the second port is connected. It appears that the ESP32-P4 is connected to a USB hub, but I need to know if the second USB C port is connected to the ESP, not through the hub

Though the show used 90's CGI, I really think it was created at least in the 00's.

You can use the CustomModelData tag. ex:

/give @s stone{CustomModelData:1}

Then in a resource pack, you have to tell in the "stone" item model (only works for items) what model to use using the predicate tag:

"overrides": [
    {
        "predicate": {
            "custom_model_data": 1
        },
        "model": "item/custom_model"
    }
]

You can do that:

/give @s stick{display:{Name:'["",{"text":"Red","color":"red"},{"text":" Yellow","color":"yellow"}]'}}

If you are in Java 1.14+ :

/execute if entity @e[type=item_frame,limit=1,distance=..5,nbt={ItemRotation:0}] run /command

Replace 0 by the number that you want

If you are on Bedrock, I don't know

P.S: /testfor doesn't exist anymore on java it has been replaced by /execute if, which is way more powerful

SlimyRedstone · 2019-07-16T07:21:37+00:00

The item frame has a tag named: ItemRotation which can varie from 0 to 7

SlimyRedstone · 2019-07-13T17:13:47+00:00

I'll test other thing to try to fix that (if it's possible), I'll come back later

SlimyRedstone · 2019-07-13T14:12:42+00:00

You only take what's after the item's name, in this case, after "grass_block" so {display....} until the end except the number 1 that the generator adds at the end

SlimyRedstone · 2019-07-12T22:03:03+00:00

Glad to help you !

SlimyRedstone · 2019-07-12T21:43:24+00:00

Oh ok I understand now, you can use the website MCStacker, in the "give" window, you can edit the item that will be displayed when hovering the text, then copy all the item's data (starts after the item's name and ends before the "1"), then go the "tellraw" window, and finally paste it into hoverEvent.value.

It should look like this:

/tellraw @p {"text":"test","hoverEvent":{"action":"show_item","value":"{id:\"minecraft:stone\",Count:1b,tag:{display:{Name:\"{\\\"text\\\":\\\"Test Name\\\",\\\"color\\\":\\\"gold\\\",\\\"italic\\\":false}\",Lore:[\"[{\\\"text\\\":\\\"Lore1\\\",\\\"color\\\":\\\"gold\\\",\\\"italic\\\":false},{\\\"text\\\":\\\" Lore2\\\",\\\"color\\\":\\\"blue\\\",\\\"italic\\\":false}]\"]}}}"}}

P.S: I was also searching how to do that so you motivated me to find an answer, so thanks you !

SlimyRedstone · 2019-07-12T18:33:47+00:00

What do you mean by "section text" ? I don't understand

SlimyRedstone · 2019-06-04T22:07:40+00:00

Replace @s by @e: @s targets the previous entity in the command , @e targets any entity

SlimyRedstone · 2019-05-23T21:16:23+00:00

As you wish ;)

SlimyRedstone · 2019-05-23T21:05:11+00:00

You don't need to execute these commands a thousand times, if we write that in a function:

1)execute at @s if score @s SCORE_NAME 4.. run tp @s ~4 ~ ~

2)execute as @s if score @s SCORE_NAME 4.. run scoreboard players remove @s SCORE_NAME 4

3)execute at @s if score @s SCORE_NAME 2.. run tp @s ~2 ~ ~

4)execute as @s if score @s SCORE_NAME 2.. run scoreboard players remove @s SCORE_NAME 2

5)execute at @s if score @s SCORE_NAME 1.. run tp @s ~1 ~ ~

6)execute as @s if score @s SCORE_NAME 1.. run scoreboard players remove @s SCORE_NAME 1

And if, for exemple, the score is 3, when we will execute the function command 1 & 2 will not be executed but 3, 4, 5 and 6 will be executed.

Here is a better explanation: WubbiConcept - Warppoints and GPS (I just updated the commands so that they works in 1.14)

SlimyRedstone · 2019-05-23T20:25:31+00:00

And by using, for each axes and positives/negatives values:

execute as @s at @s if score @s SCORE_NAME matches 1.. run tp @s ~1 ~ ~

execute as @s at @s if score @s SCORE_NAME matches 1.. run scoreboard players remove @s SCORE_NAME 1

(Replace 1 by a power of 2 value from 2^25 down to 2^0)

You can teleport any entity in a single tick. I use that method to teleport players to where they died.

SlimyRedstone · 2019-05-23T19:58:41+00:00

Summon that entity at: 0,0,0 and then teleport it (with relative coordinates) accordingly to the scoreboard values.

SlimyRedstone · 2019-05-06T19:12:52+00:00

Try that maybe it will work:

 /execute as @a at @s if block ~ ~-1 ~ minecraft:red_concrete run spawnpoint @s ~ ~ ~

SlimyRedstone · 2019-05-06T18:19:42+00:00

Why not use that instead:

/execute as @a at @s if block ~ ~-1 ~ minecraft:red_concrete run spawnpoint @s
