Hi all,
As my TTN still doesn’t work. i am trying to use a SD reader which is connected via SPI. The HTCC-AB02S has 2 SPI’s but I can’t get it working. all i am trying to do is to see if i can start the transmission with some simple lines. Can anyone help me with the way to program ? How can i change the configuration of the pines?
the code is :
void setup() {
Serial.begin(9600);
Serial.print(“Starting SD …”);
if (!SD.begin(4))
{
Serial.println(“Failed to Start”);
return;
}
Serial.println(F(“Running OK”));
}
void loop() {}
@MasterTribuno Did you get any response from heltec? @jasonXu could you help us?
Regards,
