Re: Direct IO Port Manipulation

The GPIOs have a configuration register each, but the value is set using 4 32-bit registers, namely GPIO_OUT_W1TS/W1TC and GPIO_OUT1_W1TS/W1TC. You use the GPIO_OUT_* register to modify GPIO0-31, you use GPIO_OUT1_* to modify GPIO32 and higher. When you write an 1 in a bit in a W1TC register, you'll...

Re: LCD SPI & I2S - Serial & Parallel - Speed vs Ressources

FYI, if you use the esp-idf SPI driver, the transfer should be done entirely in DMA, freeing up the CPU to do other tasks. We're aware of the 4K limitation in that driver, and I expect a MR that amongst others fixes this limitation to come through within a few days. Wrt 8-bit LCD mode: there used to...

Re: when use ESP-WROVER-KIT,always getting the message"Localhost:3333:Connection timed out."

Sorry, that's not possible. The SDMMC and JTAG pins conflict, so if you use the SDMMC pins to drive a SD-card, you cannot use JTAG. On the WROVER at least, the hardware does not interfere, so if you do not use SDMMC, JTAG works fine.

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.
