Hello!
I purchased the ESP32-S3_2.8inch Capacitive Touch Display Development Board, but it turns out that there is no SPI interface embedded. I need a LoRa SX1278 module to connect to it. Could you help with some advice? Or i2c to spi bridge because it has an i2c-interface?
Thanks in advance.
Would be helpful if you provide a link the the actual board you are using.
How many spare GPIO pins does it have, that are not being used ?
GPIO15 & 18
You wont be able to connect an SPI LoRa module, such as SX1278, with two GPIO pins.
There are LoRa modules that are accessed over via a two wire UART interface, TX and RX data. But they cannot be used with the standard LoRa libraries.
Well, that's exactly why I asked, if anyone has encountered a similar problem and if there is a solution!
