456 Hassle-Free ESP32 USB (ESP32-C3, ESP32-S2, ESP32-S3)
Переглядів 115,606
День томуThe USB feature of the new ESP32 chips is handy. Unfortunately, it is not easy to use because the information is hidden. This video shows how everything works and how you must set up the Arduino IDE to exploit the USB functionality. I promise it will save you a lot of frustration and time. And it is the basis for a future video about simple debugging with the new Arduino IDE 2.0

@drstefankrank 10 місяців тому
@@danielliden600 Take care of the correct CC1 and CC2 Resistors. Because the plug fits in both orientations, you need to bridge the pins for both sides on your pcb. Think about power. USB can deliver your 5V, but you have to step it down or use an external source. For my application I rely on the battery for power and use only D+ and D-, but I have CC1 and CC2 designed to put resistors to ground. Not sure if I do this right, but at least it works for me. Further I added pin headers for the old RS232 on the board as well as BOOT and EN buttons to be on the safe side, in case USB does not behave.

Hi Andreas. I have been in the front row for a couple of years so far. As a retired Engineer, I have been playing with ESP32S dev boards and using PlatformIO as my IDE. I was excited by your S3 video and immediately went to Amazon to look for a board that might be easier to debug with. Then got confused. Many of the S3 boards have a USB to serial chip for the 2nd USB port. Some don't. I am guessing that the USB to serial IC is there to "comfort" legacy users? The boards containing 2 USB ports but no USB chip must use the two ports you discussed in the video. I an thinking that the USB chip boards would suffer the same fate of older ESP32 needing the RESET/GPIO0 buttons. And the boards using the two ESP32-S3 ports would debug more reliably. Always enjoy your vids.... Any thoughts?

What a coincidence... I've been working on exactly this for the last 2 weeks. (complete rewrite of my ESPEasySerial wrapper to have a single interface to any possible serial port) One thing to keep in mind for the S3/C3; There is a bug in the Arduino code, which renders the serial port unusable when calling end(). (will be fixed in the next ESP32 Arduino release) Another nice thing from the CDC uart ports is that the host (PC) determines the baudrate, so it doesn't matter which baudrate you set in your terminal program to connec to the ESP.

I'm thinking you could use USB audio ( mic and spk ) device, connected to a radio with a USB "sound card" as RX/TX audio to handle encoded audio from multiple inputs , mixed/amplified/noise reduced/compressed/proccesesd etc in DSP on ESP32. The multiple inputs can be useful for multi-op pota , where each gets their own headset and controls. one in/output would be over the USB "sound card" to the radio, other outputs could be a monitor for non-op listeners. Another project option could be the generation of some digital mode content for sending to the radio over the USB sound card for TX/RX. It could be a WSPR transmitter , or maybe even an FT8 transceiver, without attaching a full computer? I've thought it might be cool to make an FT8 fox/hound and use it for an actual fox hunt? or a kind of DXepedition, if you put FT8 fox , with autorespond on a balloon , or maybe someday a cubesat :-D

If you want to use all the features of the chip and have more control over it then you need to use esp-idf and it even has the ability to include arduino as a component so you can write the same code you would in the arduino ide whilst having access to esp-idf specific functions.

Now the question do you think this is possible with Arduino or these ESP32 when i find out how the host has to speak with the multitouch display.

I can download the app and see all serial.print() via the usb-cable, BUT, when I pull the usb-cable the app slows down the sending of can-messages. It seems as if the loop is hanging on the serial.print() statements about a sec and the times out and send a message, then hangs and so on. If I restore the cable and resets it works again. So there seem to be an issue when the usb-cable is removed that affects the functionality of the code. Any ideas?

I did have a look and a second challenge (problem) pops up. Of course the sector management must make sense to the receiver (the PC). So you must emulate a disk format like FAT and not SPIFFS or LittleFS. And that is exactly what Adafruit does in the Circuit Python. The Flash file system is formatted as FAT. Now the mangement of the sectors is 1:1 and becomes pretty easy. You have no idea what you're passing, just sectors. No knowledge of files or directories needed, just 1:1 sectors. Smart!
