Identify secondary SPI interface on Wemos S2 mini
网页2023年11月27日 · Pins on an ESP32 are assignable for peripherals like SPI, but somehow the S2 is a bit different in naming the available SPI busses. If i remember correctly 2 busses are available just like on other ESP32's but the default pins are not exposed, so you should define the pins yourself.
Wrong pin number of SPI and I2C for LOLIN(Wemos) S2 MINI #10196 - GitHub
网页2024年8月20日 · I have a small project using ePaper with LOLIN(Wemos) S2 mini. Initially, GPIO36 & 35 connected to SCK and MOSI using attached pinout diagram but it won't work. Then, I found that default SPI pins in arduino IDE are not correct. So, I have modified the pin number of RXTX, SPI and I2C in pins_arduino.h. Original:
S2 mini — WEMOS documentation
网页ADC, DAC, I2C, SPI, UART, USB OTG. Compatible with LOLIN D1 mini shields. Compatible with MicroPython, Arduino, CircuitPython and ESP-IDF. Default firmware: MicroPython.
Use LoLin V3 pins starting with 'S' in Arduino
网页2018年3月3日 · Quad-SPI uses 4 data lines, but you can also operate the chip in Dual-SPI with 2 data lines (refer to here). That means that you are able to cut 2 of the 4 data lines, GPIO9 (SPI_HD, S2 on the board) and GPIO10 (SPI_WP, S3 on the board) on the PCB from the ESP8266 to the flash chip and then use these two GPIO pins arbitrarily.
Wemos s2 mini spi - esp32-s2 spi issue? - Arduino Forum
网页2021年12月23日 · I am trying to get the WEMOS S2 MINI to drive a TFT and have run into some basic problems with the SPI. This board uses an ESP32-S2 with 4MB FLASH and 2MB PSRAM. I am using ESP32 board core 2.0.1-RC1 and Arduino 1.8.15 The program below produces a 20MHz 3.3V clock on pin 36 but the MOSI data on pin 35 is only about 1V peak to peak.
HyperSPI with LolinS2-Mini change default pin-in - GitHub
网页2023年3月10日 · 5 Change default data pin (-DDATA_PIN=2) to desired output. you must compile a firmware using next steps. The SPI input pins (the ones used to connect to the Rpi) can also be changed, but this requires changing one line in …
ESP32 S2 mini custom SPI with GxEPD2 - Page 2 - Arduino Forum
网页2023年12月23日 · For an experiment I tried do remap the SPI pins of my ESP32 S2 mini connected to my 2.13 inch Epaper display v4 from Waveshare. Using the standard SPI pins MOSI: 11 MISO: 9 SCK: 7 SS: 12 it works perfectly fine.
[lolin_s2_mini.md] Add info about custom SPI/I2C pinouts. #1268
网页2023年10月26日 · Because there no I2C/SPI labels on S2 Mini, there are used def from Wemos MP: SCL - GPIO35 SDA - GPIO33 SCK - GPIO7 MOSI - GPIO11 MISO - GPIO9 But in web there are present different pinout on image...
Hands-On With the Wemos S2 Mini ESP32 Development Board
网页2022年8月1日 · It comes in a form factor compatible with the ESP8266-based Wemos/LOLIN D1 mini, and the S2 mini can thus work with D2 mini shields. Ground, Vbus, and 3V3 pins are in the same place, though the IO pin numbering is different, so any swaps would certainly require a bit of reprogramming for proper functionality.
