Re: video libray with ESP32

You need to expand a little bit on your setup. Windows/Linux/Mac? How do you send your joystick commands and why does it not work? At the moment your only question is if it's possible, and the answer to that would be 'yes', and that would probably not help you.

Re: Playing gif's with Esp32 & TFT Lcd display

Find or write a GIF decoding library, find or write a support library for your TFT, connect the two together and there you go.

Re: Specification of ESP32 NIC

No, sorry, the WiFi NIC itself is more-or-less a black box... Can you tell me why you are trying to get this info? Are you trying to solve a specific problem?

Re: guru meditation error

First suspect would be the power supply to your board. Make sure that it's capable of delivering 500mA at least. If you use a devboard, make sure the USB cable is not too thin, and the USB port can deliver enough oomph to properly power the ESP32. Also moving this to general discussion as it is unli...

Re: Can't get unit test to work with IDF 4.0

No clue, but it may be easier to just disable that specific unit test somehow, it's pretty old and tests ROM code that is well-proven by now.

Re: SPI Master Slave handshake with spi_device_queue_trans

Not sure about when it's called, but when post_trans_cb is called, the transaction still is 'owned' by the SPI driver; you only get it back when get_trans_result returns it.

Re: Where to download .pdf of the idf doc?

No worries there. We have offices in Brno and Puna that are outside of China and as such unaffected, and most Espressif people in China can do their work remotely as well.

Re: SPI Master Slave handshake with spi_device_queue_trans

You could in theory create t_send items dynamically, using malloc() and free(), but you'd probably still be limited by the fact that your SPI queue has a limited amount if items it can contain, so it won't really help here. Can you expand a bit on why you have a separate Tx and Rx task? Does this co...

Re: esp32 newlib migration or access via Arduino ide

Newlib already is part of ESP-IDF, and as the ESP32 Arduino environment is built on top of that, you should be able to use it straight out of the box.

Re: which external flash can i use for replacing internal flash

Because while both can be accessed over SPI, the higher interface to a SPI flash memory chip (so the commands, bitfields, general way the interface works) is entirely different from the SPI mode of an SD card. The hardware that is used inside the ESP32 to access it is only capable of speaking the pr...
