Re: TFT spi at 60MHz

For the ESP it is in theory possible. Keep in mind that the standards parallel RGB (24bit or 16bit wide) bus (the one that has HSYNC and VSYNC signal) are not possible with the ESP32, as in this case you have to keep a full frame buffer in the ESP RAM at all times, and send the frame buffer out com...

ESP IDF Environment only works one time

I decided to install ESP-IDF, I use CLion and I work in the project "hello_world". Using CLion, I can build, flash etc. But when I want to use idf.py in the command line it does not work. It only works If I go back to the root directory, run export.bat and then return back to the project path. But t...

Re: ESP32-CAM Power Saving - XCLK undefined reference issue

FYI, I have solved the "calling XCLK routines from Arduino" issue, they need to be declared like so: `extern "C" { esp_err_t camera_enable_out_clock(camera_config_t *config); void camera_disable_out_clock(); }` It saves a bit of power and the clock can still be restarted and a picture taken again. ...

Re: ESP32-S3 is not booting, or is not even trying to

Thank you! Now there are normal characters showing.. finally. Okay so I could upload a program to my ESP32-S3, and now there is the next problem: I can't exit the bootloader: serial_monitor_3.jpg It always says this message. I uploaded my program with IO0 and IO46 connected to ground, uploaded succe...

Re: ESP32-S3 is not booting, or is not even trying to

Hi Craige, Thank you for your reply. That looks very interesting!! Uhm I don't have common ground. Just connected TX to RX, and RX to TX of the 340C and connected that thing to USB-C. 20230104_173619.jpg Everytime I press the Reset button, the message is slightly different. Is that, because the grou...

Re: ESP32-S3 is not booting, or is not even trying to

THANK YOU SO MUCH!! Never would've thought of that, I was literally just about to throw it away but now i removed the CP2102 with a knife and sand paper (XD) and soldered wires to RX and TX to hook up to a CH340C. BUT Now I get this when I read Serial Monitor with BAUD 115200 (I tried different BAUD...

Re: ESP32-S3 is not booting, or is not even trying to

Hey, thanks for your reply! I will remove the vias. Can you explain why I need to connect RX to TX and TX to RX? Would you recommend to build a circuit for RTS and DTS like here? https://i.stack.imgur.com/Jtx4J.png And do you know why my ESP32 is not responding or how can I tell that it is trying to...

Re: ESP32-S3 is not booting, or is not even trying to

Hey there, here are all my schematics (I unfortunately can not post more than 3 images on here for whatever reason so I uploaded it to imgur: https://imgur.com/a/r7bCllL If anybody can find something wrong, I would be so happy. My other thought would be, that in my PCB Design itself I made some wron...

ESP32-S3 is not booting, or is not even trying to

Hi there, I've been trying around for hours to get my custom made PCB to work, but it does not want to. I designed everything in Easy-EDA Pro, and ordered everything with all parts placed from JLCPCB, the board came yesterday. I have the following schematics: schematic.jpg schematic_1.jpg Here is th...
