Re: ESP32 5GHz

Nothing I can make public that's more than 'we're working on it', sorry.

Re: open drain output

Not all pins support open-drain because not all pins can be configured as output (specifically GPIO34 and higher are input only). Furthermore, open-drain at least in theory seems to satisfy the datasheet requirements: configure the pin as open-drain, then write a '0' ad an output value to turn the s...

Re: Real-time data streaming over WiFi

Do you need low latency? If not, just collect a heap of samples (100 or so) and send them as one packet; if you do it like this, you can happily use whatever protocol you fancy. If not, most protocols probably still are feasible, but you'd need to try. I'd personally just go for an UDP stream if you...

Re: PWM controlled fan tacho wrong

Is this measured in the situation where your code returns faulty readings?

Re: my IRQ calls when a driver sends data via SPI

I honestly don't quite get what you want us to do about it... seems you already found somewhat of a working solution (disable interrupts) and you're not saying what your additional problems are with that, nor do you post any code so we can look if it makes sense.

Re: ESP32-deepsleep don't come back with resetreason 5

Hard to say. No chance you can capture the serial output when that happens? That might tell you more.

Re: TTGO-T-display + SD card

From a technical PoV, the 'all ports are freely remappable' statement is exactly that: for most peripherals (UART, SD, I2C, I2S, ...) you can pick the GPIO the signals are routed from/to using the GPIO matrix. How that's implemented obviously depends. Also, not all ports make sense to map to: you do...

Re: How do I use esp32 as an external RAM for other microcontroller?

Well, you have a whole heap of external interfaces (SDIO, UART, I2C, SPI, ...) you can use to communicate with the ESP32; as long as you write the software and the other side knows what protocol to speak, there's nothing stopping you from implementing a communication protocol that also allows you to...

Re: TTGO-T-display + SD card

Yes. The SPI pins of both user SPI peripherals are freely remappable.

Re: ESP32 two CAN drivers simultaneously

Why would you? The ESP32 only has one CAN peripheral.
