OLED and SPI on Wifi Kit 8
The OLED I2C clock and SPI clock are on the same pin GPIO14, so is there a way that I can use an SPI device like the MCP 2515 CAN controller and the display together?
Please check http://stefanfrings.de/esp8266/#wifikit8 (it is in German, but google translate does a great job). On my board it is version A: GPIO4 is I²C data and GPIO5 is I²C clock, perhaps this helps...
