Esp32 hardware spi

  • The ESP’s extremely flexible hardware peripheral routing matrix allows it to assign the SPI functions to any pins, but the Arduino implementation is preset to a default pinout, so you just need to look it up, and hook up MOSI to MOSI and so on. As of now, it only uses one of the ESP32’s two free SPI units.

  • From the board schematics. You can learn that ESP32 shares SPI1 pins and has two additional signals: WF_INT (GPIO 10) and SPI_CS2 (GPIO 9). The former is used as a “handshake” signal from ESP32 to FE310, the latter (as its name says) should be used as a hardware-controlled CS signal.

    You must do the hardware mod. Some of the A0-A5 pins on the TTGO board are analog only. Hence the need for hardware mod. The TFT control signals must be digital. Yes, these shields "work" on the ESP32 but are a bit wasteful. Most of your GPIO pins are used up. It is a lot better to use SPI screens with an ESP32 or ESP8266.

    Feb 28, 2017 · SPI drivers that prefer hardware CS/DC pins. In a previous post Paul said ILI9341_t3, ST7735 and TFT_ILI9163C are the drivers he knew about at the time that used the hardware CS/DC pins, but I suspect other drivers (particularly other displays) have gotten optimizations added as people feel the need for speed:

There are three main registers that control the hardware SPI settings in terms of data that is sent and received. SPI_USER - Controls which functions of the SPI controller will be used. Essentially used to toggle settings on and off. SPI_USER1 - Defines Address, Data Out (MOSI), Data In (MISO), and Dummy Data lengths.
