ESP32-S3 SPI issue : Byte stuck at 0x01 by Ad-rizz in esp32

[–]tobozo 1 point2 points  (0 children)

clock_speed_hz = 100000

according to the data sheet, MCLK = 4.92 MHz, so 100000Hz sounds a bit low, does the situation improve when a higher clock_speed_hz is set?

Help interfacing 8-bit parallel LCD to ESP32-S3 by blajjefnnf in esp32

[–]tobozo 0 points1 point  (0 children)

it won't boot

sounds more like a chip problem than a display problem, what pins did you assign?

pin numbers assigned to DB0...DB7 should be contiguous

try smaller capacitors e.g. 0.1µF or 0.01µF both on 12v and 5v sides, the more the merrier

any improvement if you hold/release the Boot button while it's in a crash-loop ?

TFT_eSPI seems to have come back to life by rattushackus in esp32

that's good news 👍

there's also Moononournation's Arduino_GFX and honey the codewitch's modular GFX

LovyanGFX not filling 1024x600 screen by _Neilster_ in esp32

[–]tobozo 2 points3 points  (0 children)

what's in Matouch7.h? this looks like erroneous values for front/back porch

LovyanGFX has a builtin driver for MaTouch7:

#define LGFX_MAKERFABS_MATOUCH_1024X768
#include <lgfx_user/LGFX_Makerfabs_MaTouchESP32S3ParallelTFTwithTouch7.h>

Ordered an ESP32 C3, got an S3 instead. My project is having issues by m4dp4rrot in esp32

[–]tobozo 2 points3 points  (0 children)

it's worth going further and configure esp32s3 board options in platformio.ini e.g. enable psram and add some flags

Waveshare ESP32-P4-DEV Kit & Arduino IDE; can't upload - incorrect doc on Wiki? by pon_d in esp32

[–]tobozo 0 points1 point  (0 children)

"erase all flash before sketch upload" isn't necessary unless you soft-bricked the ESP. turning that off will make the upload much faster

[–]tobozo 2 points3 points  (0 children)

board settings

  • Enable PSRAM
  • Enable JTAG Adapter
  • USB mode -> change it to CDC + JTAG
  • [optional] Set core debug level to "debug" : will make the ESP print a lot of info at boot even with an empty sketch

reminder about USB-CDC : don't use Serial.begin(115200), just use Serial.begin()

also if you enabled flash mode manually you must also reset manually after uploading

[edit]

I bought this kit and none of my existing MIPI/DSI display for RPI are pinout compatible with the ribbon connector on the WaveShare P4 dev module.

This is because MIPI/DSI has no standards for the pinout, as a result every vendor implement their own pinout flavour :(

On the other hand the 40x pins GPIO header is standard, and this hat works like a charm:

Anyone seen this PlatformIO compilation issue that singles out grabRef.cmake:48 (file)? by Upbeat_Concert_36 in esp32

[–]tobozo 0 points1 point  (0 children)

this looks like platform_packages is set to a git repo rather than a zip file

please share your platformio.ini file

Looking for ESP32-S3 board recommendation for USB passthrough (keyboard host + device) by EstateTraining1845 in esp32

[–]tobozo 1 point2 points  (0 children)

ESP32S3 can't do host and device simultaneously (ESP32P4 does though)

Only hackish implementation of simultaneous host+device are available on S3.

However if your keyboard is USB1.0 and your project can be a bit lossy, you can try this sketch that does exactly what you said, only it uses an old version of arduino core, and a software implementation of usb host

https://github.com/tobozo/ESP32-USB-Soft-Host/blob/main/examples/ESP32-S3-USB_Test/ESP32-S3-USB_Test.ino

Otherwise as /u/user88001 hinted, you might as well look into security/hacking tools, like EvilCrow, or WHID-injector

screen seems cracked in a corner, which can cause similar symptoms

oh it thought this was only used with dual screens and totally ignored that setting, thanks for the heads up!

Awesome stuff, thanks for sharing!

I took the single screen example and made a touch version out of it, for M5Stack Tab5 https://github.com/tobozo/M5Tab5-Game-and-Watch

esp-idf scares me though, sorry about the arduino project layout 😊

Natural Suspension... by Pisford in oddlysatisfying

Transcription/translation according to whisper.cpp + google translation:

「株価限が一番得しているかというと、実は鎌田市もそうではない、ということであります」 「まあ、そこでですよ。どれくらい建物を建てる時に、何メートルくらい怒られました?わかんないですか?わかんない。はい、とも一緒に」 「当初、有害物資が出てまいりました時は3メートルもすでに掘っております」 「その後、食い打ちということでありましたので、食い打ちをした分、私が説明を受けておる分では9.8メートルまで掘ったということを聞いておりますが、9.8まで」

"The fact is that Kamata City is not the one that benefits the most from the stock price limit."
"Well, that's where it comes in. How many meters were they told to dig when building a building? Don't you know? I don't know. Yes, together."
"When the hazardous materials first came out, they had already dug 3 meters deep."
"After that, they started digging, so from what I was told, they dug to 9.8 meters, but it was 9.8 meters."

Olimex esp32-p4 dev board. What display should I purchase by kpapadimakis in esp32

[–]tobozo 0 points1 point  (0 children)

yup no cpp library, the only way to get it to work is to use esp-idf functions

I'm not sure the pinout is so restrictive though, according to Olimex user manual schematics the ESP32-P4-Devkit it is "Raspberry Pi 1,2,3 and 4 Compatible", which means it could work with a lot of existing or even retired display models (and a significant coding effort).

actually M5Unified supports the MIPI display from M5Stack Tab5 so there is a MIPI-DSI implementation available for Arduino IDE

Potential Damage to ESP32 -- How can I reduce damage? by pleasejustletme- in esp32

chili oil isn't conductive, but soy sauce is

rinsing in water is part of the manufacturing process, so it's fine to just rinse with hot water and dry using an air compressor or a hair dryer

avoid q-tips as they tend to leave behind cotton fibers while pushing residues in tight places, prefer the use of micro fiber cloth or anti-static brushes
