So usually what I do is have each device increment it's state according to received lower frequency clock signals, like how a RTOS will check for things every ms or so. Basically each device has it's CPU clock, and it's "program clock" that's way slower and only handles big changes. In my case, big ...

So I have a bunch of devices that all use the ESP32 which I need to synchronize because the clocks are never quite precise enough over a long time. My usual solution to this is to have one "master" device send out "clock" pulses at a much slower rate to the other devices to increment the state so th...

I want to use the dual DAC on the ESP32 and am having some trouble understanding the datasheet. I've found that noise from my input power supply shows up on the analog output. I would like to install a choke and filter to the analog domain power pins to help clean them up from switching noise produc...

I am trying to design a board based on the ESP32-PICO-D4 module, but on the real hardware the USB programming is inconsistent. The issue seems to be tied to RTS/DTR use to put the device into boot mode; if I manually push the BOOT and RESET buttons it properly uploads code. However, when it finishes...

Yes, and an added ground pin would make the QFN asymmetric, you'd probably end up just putting a ground pin on each side. It's rare to find a sophisticated chip that only has one ground pin lately. I'm not so worried about the soldering, I have a hot air rework station and solder paste so I can defi...

To be honest, the ESP32 is so incredible compared to every other chip I've used before at that I find it hard to think of improvements! Adding hardware USB 2.0 would be nice so that I can avoid adding a USB converter chip and I imagine potentially higher speeds, so long as it's still simple to uploa...

I wonder how much of your issue with using a development board is purely that they use a linear 5V to 3.3V regulator. They just throw 33% if the power away right there. Seemed like a strange choice for a low-power chip, but I suppose it's a lot cheaper. Depending on your system, you might be able to...

Update: I managed to get some fairly sophisticated stuff working reasonably well, but I think there may frankly be some bugs in the library. I'd love to know if they are not bugs and that I'm doing it wrong! Okay, so first, I wanted to make the connection optional, but WiFi.status() doesn't seem to ...

Apologies for the newbie questions, I'm having a hard time using search terms for the forum since I think the stuff I'm asking about I don't know the right words for. I build custom scientific equipment, and I'd like to shift from USB based communication to a flexible scheme that can allow wifi or e...
