Re: ESP32-DevKitC in Ubuntu on VirtualBox

I see, you use the DevKitC.
Have you pushed down the "boot"-Button while programming? :)

Re: VGA driver ?

Only a hint: You should take a 8-bit IF for GLCD and merge together https://s22.postimg.org/nrsef145d/UZE_Box.jpg with this https://esp32.com/viewtopic.php?f=19&t=702 look also http://www.jcwolfram.de/projekte/avr/chipbasic2/hard.php and: https://www.mikrocontroller.net/topic/377963#4292846 A lot of...

WiFi Web Server LED Blink

The simplest Webserver-Sketch I've found. https://codebender.cc/sketch:37120#SimpleWebServerWiFi.ino For my "SparkFun ESP32 Thing" I only commented out the: /* // check for the presence of the shield: if (WiFi.status() == WL_NO_SHIELD) { Serial.println("WiFi shield not present"); while(true); // don...

Re: Where to get peripheral input clocks

I also search an easy way to get the input clock frequency for peripherals.
Need the XCLK for OV7670 without the LEDC-module.
Free running (with start/stop) at a GPIO-Pin(frequ. 10 to 48 Mhz)..

Re: Camera

Thanks for your hints!
At this point i decide to roll-back my Arduino-IDE.
Unexpectedly where everywhere Arduino15 folder are filed under Windows.
If there were no hardware i need like PC-Scope/Generator(Vellemann) and anymore I would prefer a Linux-Distri.

Re: Camera

You can take GPIO32..39 as Input. That's right! But I need an 8-bit Output for the ILI9325 (ucg-lib) and the pseudo-Input for CAM at the same pins.. p.s.: Have you found the missing Vsync ? Use you the VSPI for your ILI9341? At Prgr.3 I display the contents of the SD-card(not included-->see http://e...

Re: Camera

This was the right hint. I've changed it to : timer_conf.bit_num = LEDC_TIMER_13_BIT; and it compiled. 13-bit deep timer, i don't know, but seems to be right? btw.: The 8-bit Bus for the Display-Output Pins -->d0 to d7 13,12,14,27,26,25,3,4 Don't use Pins 32 to 39. These pins are the same for input-...

Re: Camera

I want to be as closed as possible to Krzysztofs great https://github.com/krzychb/esp32-cam-demo#connect ; Only want to port the idf-project to Arduino-IDE without freeRTOS. The famous DMA-transfer is good to look at for further use. I think i would do the reading out of the GRAM-Display with this. ...
