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

PHY's likely not going to happen, given the process requirements likely are pretty different from the rest of the chip; I don't think we can integrate the two on one silicon die easily.

Re: I2S Record to SDCard using FATFs

Code: Select all

for (int i = 0; i < buf_len / 8; ++i) {
			partWavData[2*i] = buf[8*i + 2];
			partWavData[2*i + 1] = buf[8*i + 3];
		}
Why 8?

Re: ESP IDF get GPIO level at time of interrupt

Not if the signal jitters back and forth with a frequency that's higher than the latency between the interrupt and the time the GPIO gets read out, no.

Re: Fastled and wifi

I'd still like to see the crash dump as well if you can, as I don't have the means to easily reproduce your setup here. (Also, my intuition tells me that 1000 bytes of stack is on the low side for your task... perhaps try to increase this to 8K and see if the problem persists?)

Re: How to send data via wifi faster?

Don't read and send only 2 samples at the same time. Each time you call i2s_read/websocket.send, there is a fixed amount of overhead that needs to be done regardless of how much data you read or send. If you only read and send 2 samples at a time, that adds up very quickly.

Re: help please

...but did you manage to successfully flash the Arduino code to the board over the serial cable? If you don't get that to work, WiFi won't ever work.

Re: ESP IDF get GPIO level at time of interrupt

There's no real characterization possible for bounce noise, as it's partially an analog process... all you can know is that it's usually over after a few ms... so best you can do is start a timer in the interrupt (and disable the GPIO interrupt) and read the value of the button when the timer expire...

Re: Getting a "PermissionError" while scanning directories inside "/spiflash"

Do you actually have files in the spiflash structure? Asking because there is a bug in your code: on an empty directory, the first readdir will return NULL and the result of the second readdir will be undefined.

Re: App finished, I upgraded now can't build. Which version was my toolchain?

The toolchains might/will indeed differ, but if you use the installer or the install.sh script, I think they will be installed in separate directories and esp-idf will know which one to use. If you want to keep a certain version of esp-idf tightly coupled to the project you're working on, it may be ...

Re: "ESP-NOW" protocol on Android and ios smartphones

Yes, I understand what you want. What I am saying is that WiFi Direct at this point most likely is too limited in general use for us to make it into a high priority to develop.
