Problem with the spi_bus_initialize
Posted: Thu Feb 15, 2024 3:24 pm
Hello,
I would like to use the hello world example from this code (https://github.com/manuelbl/ttn-esp32/tree/master).
I’ve been trying for days to get my ESP32 Dev 38 pins to work with an RFM95W 868 MHz so that I can use the TTN. Unfortunately I can’t get any further and I’m desperate.
I use plattformio as the IDE. When it comes to pin assignment and plugging, I’m actually sure that it fits. The names of the pins are on the RFM95W and I found this graphic for the ESP32.
https://arduino-projekte.info/produkt/n ... p32-38pin/
I also ran the following code from https://randomnerdtutorials.com/esp32-s ... 2-spi-pins to check this.
The error message says that the arguments of the called function are incorrect. Unfortunately, after my research I can’t get any further. I hope the information is sufficient and thank you very much.
