Hi. Below is a test program I am using for a project that uses am ESP32-S3 device. I am using the USB-to-Serial internal support (pins 19 & 20) for both uploading the code as well as serial communications when the application is running. Oddly, the code uploads fine. The odd thing is that I cannot e...

I am not sure what causes the pop at the beginning of a play but I do know that if the library supports the use of the SD line, that can be mitigated. The crackling is most likely cause by ringing on the LRC, BCLK, and/or the DIN lines. Just add small resistors in each of those lines and that should...

Perfect. Thanks very much.

I am a big fan the the ESP32 product line. I have plenty of experience starting with the development kits through various modules. I have a new project that does not need the BLE or WiFi functions and I was thinking of using the ESP32-C3 SOC. I haven't found any resourse material other than the IC d...

I am working on a project that used an ESP32-C3-WROOM that will control a servo. The most popular library for EPS32 servo control seems to be ESP32Servo by J.K Bennet. I am having trouble getting it to work. Even the simple sample program "Sweep" doesn't work. (It compiles and loads but the pulses a...

The documentation isn't all that obvious but careful attention needs to be paid to the state of the strapping pins. I looks like both GPIO45 and GPIO46 should be low for boot loading. Give that a try.

Harbaughfan, (I won't hold that against you.) Glad to see that your project worked out. Mine did as well although I made a few different decisions. I too used the DEV board schematic as a guide and had no trouble with the NC or zero value components. I used all 1206 components. I bought a resistor a...

OK. I get where you are going but what you are showing in your schematic is not the way to get there. First off, 4 AA batteries at 1.2V each gives a total of 5.8 volts. That gives your 5V regulator only 0.8V to work with. I see that it is an LDO but that still isn't much margin and it will go away a...

Thanks. On with the project!

Thanks very much. I would have preferred a different answer but a correct one is probably better than a preferred on.
