I have been successful programing ESP32 before approx 2 years ago when the Arduino IDE used AVRISP MkII now it uses Esptool it seems not to upload the sketches.All I get at the end is a Full panel of LED (single panel color RED) and when I press the EN button I loose 4 vertical LEDs and hit it again I loose further vertical 4 LED until the whole panel is turned off
Can any person put some information on this. I have been using Arduino IDE for the past 8 years with no real problems. I now using Arduino 2.3.2 I was using Arduino 1.8.15
Welcome to the forum
The sketch upload will either succeed or fail, it will not upload just part of the sketch or change the logic of it in any way
Please post the sketch that you have a problem with, using code tags when you do
In my experience the easiest way to tidy up the code and add the code tags is as follows
Start by tidying up your code by using Tools/Auto Format in the IDE to make it easier to read. Then use Edit/Copy for Forum and paste what was copied in a new reply. Code tags will have been added to the code to make it easy to read in the forum thus making it easier to provide help
A schematic of your project and details of the hardware used will also be helpful
Hi thank you for your quick reply. I have been doing some more testing and find out the esptool is ok uploaded a simple blink sketch and uses Gnd an GPIO 23 with an LED (all good) I think I may have damaged the ESP32 not sure.
I am using a ESP32 Wroom 32D as well as some new ESP32 Wroom 32U
I see the ESP32 Wroom 32D and 32U is not recommended for new designs, as per their data sheet .
What model would you recommend?

My main aim is to P10 LED Modules in a sign I have written my own sketches and the have worked before however to double check I used a sketch written by Khudhur Alfarhan who also written the DMD32 Library .
I have sent you a pic of my PCB (FYI)
Thank you
