Re: EZSBC esp32 dev board spi pins?

I don't do too much with Arduino, but the plain esp-idf has an spi-master example controlling an ILI9341 LCD. Maybe you can use that to see if your hardware works?

Re: Laboris ESP32_new_spi_master_example help

Wrt Arduino, I can't help you, I fear. If you just want to get something to work, however, there's a SPI-master example in the esp-idf that controls an ILI9341 LCD. Maybe you can use that to check your hardware.

Re: 100microsecond timer in esp32

You can probably use any of the timer sources for this... one of the timer groups, the LED PWM controller timers, maybe even the built-in Xtensa timers if you do not need clock switching... For what exactly do you require this, however? It might be that using a dedicated hardware peripheral is more ...

Re: Laboris ESP32_new_spi_master_example help

What problem do you have that causes you to need to disable HAL locks, even if you do not even know what they are?

Re: Which ESP32 module should I get?

We (=Espressif) do not make these modules and I do not have experience with them. However, from the picture, they look like straightforward WROOM32 modules with an LDO and an usb-serial converter. As long as you keep in mind the IO-pins you need for the tutorials may be on different physical pins, I...

Re: EZSBC esp32 dev board spi pins?

Well, you're posting on the forum of the chip manufacturer, but have questions about development boards not made by us and libraries that we did not make - while the forum is open for questions like that, the amount of support we can give you for this is limited.

Re: UART sends only Mojibake

Erm, are you trying to compile ESP32 stuff using the ESP8266 toolchain/SDK? That's not going to work, compiling stuff for the ESP32 needs the ESP32 toolchain and esp-idf as a sdk.

Re: DEEPSLEEP_RESET

Yes, seemingly I derped and didn't remember the pullup/down enable call uses the RTC domain on RTC GPIOs. Will edit my post, I think there's something else keeping the pullup/downs from working correctly.

Re: DEEPSLEEP_RESET

That is because [s]gpio_set_pull_mode sets the pull-ups and -downsa in the digital domain, which gets powered down when the CPU enters deep sleep[/s](untrue, see edit), leaving your pin floating. If you do not pull it up or down externally, it'll just be flapping in the breeze, picking up charge fro...

Re: EZSBC esp32 dev board spi pins?

Doesn't the maker of these boards release the schematics and/or pinouts of the thing?
