Hi there,
I’ve been trying to dig up if GPIO26 is usable in GPIO26 on Heltec WiFi LoRa 32 V3/V4, but it’s a bit inconclusive.
In the Espressif spec I found
“GPIO pins already allocated or not recommended for use: GPIO26, GPIO27, GPIO28, GPIO29, GPIO30, GPIO31, GPIO32 : SPI0/1 interface connected to
the in-package flash and PSRAM, or recommended for the off-package flash and PSRAM.”
So, does this mean it’s a complete no-no?
Thanks
