- Mon Jul 02, 2018 4:17 pm #76810 I'm trying to get the HSPI Master demo from https://github.com/espressif/esp8266-rt ... SPI_Master working. On Pin D5 it just spits out garbage (I except a nice 10Mhz clock). Any idea what's wrong? I'm using the Espressif RTOS V2.0. I can reproduce the same on a Wemos D2 and Nodemcu board.
