Re: What would you like to see in The Next Chip?

No silicon bugs? But where else would our software developers get the thrill of running into a problem and not knowing if it's the chip or their program? And what other excuse would they have to talk to the digital guys? /s

Re: WiFi power spikes

Fyi, just talked to a colleague: I may have recognized the spike wrongly; it's more likely to be a WiFi Tx spike.

Re: What would you like to see in The Next Chip?

- Hardware accelerated graphics: What exactly would you like to see? We already have the hardware to control parallel displays in hardware, is there anything you'd like to see added to that? - More speed on GPIO: Will look into that. Agreed that the APB bottleneck feels somewhat uncomfortable for bi...

Re: Simplest high quality beep

Can it be hackish? If so, something thay may work is taking the two 8-bit DACs and using a resistor network to hook them together in an 1:256 ratio? If you do this, you effectively have an 16-bit DAC (although the exact precision depends on the tolerance of the resistors, as well as the load on the ...

Re: Serial and WiFi LED Strip Unreliability

Sorry, no idea, I personally don't use Arduino. Your code doesn't have any obvious flaws; if no one responds here, you may want to try filing a bug against the FastLED repo.

Re: WiFi power spikes

Yes, this is most likely the WiFi calibration, which is known to generate a spike like that. It's the reason we advise people to use at least a 500mA-capable power supply in the hardware design guidelines.

Re: Problems using Gpio36 as gpio sensor_vp

I was mostly idly wondering if the devboard could have capacitors on that pin which can mess up things. Seemingly it does... but I'm not sure if a 270pF capacitor to an unused pin can lead to what you see. Just for my reference: you're trying to use a physical switch here, not the capacitive touch f...

Re: What would you like to see in The Next Chip?

USB Device+host: As far as I understand, dual-mode doesn't take up that much more silicon (protocol is nearly the same anyway), so we'll probably strive for that. Integrated PHY is something I want as well; specifically for USB1.1 it should be possible. Quadrature decoder: You can actually already d...

Re: What would you like to see in The Next Chip?

No, but that is a software thing. You can set the RTC to a certain date using (S)NTP or another method, then use mktime() to get the Unix timestamp (aka the amount of seconds since midnight 1-1-1970) of whatever date/time you want to have an alarm on, get the current Unix timestamp by calling time()...

Re: What would you like to see in The Next Chip?

Some feedback; I'm not promising anything but just to set expectations: - USB - I can't promise anything, but as long as you don't expect USB3, we'll likely have something for you. - More ram: That's kinda hard... the largest part of the chip already is RAM, and making more of it RAM decreases yield...
