Heltec LoRa 32 V2 - cannot find the SPI chanel.

[risi37]

Hello everyone,

Recently I have purchased a Heltec LoRa 32 and I would want to use an ePaper display with it. The epaper module uses SPI communication, while reading the ESP32 D0WDQ6 data sheet it says there that it supports 4 SPI channels. So the heltec board uses SPI communication for Flash memory, Oled display and LoRa module. My question is:

1. Can I use the SPI pins for Oled (or LoRa), to drive my ePaper module. I do not need the oled or lora for this project, so I was thinking of just using the same pins and dropping one of the mentioned modules.

2. Since it has 4x SPI channels, I cannot seem to find the 4th SPI communication in the given material. Can somebody help me here?

All the best,
