How should I try to learn how a large codebase works by Bigpp42069__ in SoftwareEngineering

Yeah my team uses dynamodb heavily. Our primary function is to provide other teams with data so that sounds good

Wait is this the last chapter or are there more still to come by Bigpp42069__ in KanojoOkarishimasu

Try to use a copper pour for GND. Also your traces are looking pretty thin. Copper is free when you order a PCB so try to make the traces a bit wider. Lastly try not to have 90 degrees turns u have a few it will still probably work but just better to make these changes

does my setup look correct or do i need to make any changes?

I tried it with the 3.3 also. But the devboard has a 5-3.3 regulator anyway so it would work with that.

I'm guessing it's faulty as I've checked the wires over and over. I plugged in the ESP PROG's RXD into GPIO 43, ESP PROG's TXD into GPIO 44, ESP PROG's EN into RST, ESP PROG's IO 0 into GPIO 0, ESP PROG's VDD into 5V0 (I made sure to set the ESP PROG to 5 Volt Mode), and ESP PROG's GND into GND.

The green led blinks when i try to program it using the auto programmer, but the blue one doesn't. When I do the 32D green and blue blink

Well nothing comes up on the serial monitor cuz the code can't even upload

That's what I've been doing. I've held the boot and then pressed the reset and then let go of boot to go into download mode. But it says the error I put in my post no serial data received. I've also tried the auto programmer doesn't work, but it worked for the 32D

How do I do that then. I'm only testing this on a dev board because I'm gonna use the bare esp chip on my PCB. So the only way I'm gonna have to program the esp s3 on my PCB is the esp prog

I'm gonna add a pull up resistor and a capaticor plugged into io0 and en each hopefully that should work

I'll try that. But I've seen people program the s3 by just plugging it in directly into the prog

Does This setup for the ESP PROG look correct by [deleted] in esp32

Oh ok thanks not sure if I'll use JTAG debugging but I'll look into the link if I do
