ESP32 SPI issues

[doggoegg]

Hello, i am struggling with a spi connection between a ESP32-S3-DevKitC-1 (Master) and a ESP32 C3 Super Mini (Slave)
My Code:

#include <Arduino.h>
#include <SPI.h>
#define SCLK  4
#define MISO  5
#define MOSI  6
#define SS    7
void setup() 
{
  Serial.begin(115200);
  pinMode(SS, OUTPUT);
  SPI.begin(SCLK, MISO, MOSI, SS);
  SPI.beginTransaction(SPISettings(1000000, MSBFIRST, SPI_MODE0));
}

void loop() 
{
  digitalWrite(SS, LOW);
  
  byte dataToSend = 0x42;

  byte receivedData = SPI.transfer(dataToSend);

  digitalWrite(SS, HIGH);
  
  delay(1000);
}

#include <Arduino.h>
#include <SPI.h>
#define SCLK  4
#define MISO  5
#define MOSI  6
#define SS    7

volatile byte receivedData;
volatile bool dataReceived = false;

void setup() 
{
  Serial.begin(115200);
  pinMode(SS, INPUT_PULLUP);
  pinMode(MISO, OUTPUT);
  SPI.begin(SCLK, MISO, MOSI, SS);
  SPI.beginTransaction(SPISettings(1000000, MSBFIRST, SPI_MODE0));
}

void loop() 
{
  if(digitalRead(SS) == LOW) 
  {
    receivedData = SPI.transfer(0x00);
    
    Serial.print("receives data: ");
    Serial.println(receivedData, HEX);
  }
}

I tried it in ArduinoIDE with the boards selected:
"ESP32S3 Dev Module" and "Nologo ESP32C3 Super Mini"
in the Serial Terminal i just receive 0

I also tried it in Visual Studio Code with the Platformio extension, i selected:
"esp32-s3-devkitc-1" and "seeed_xiao_esp32c3"
i got the same result

i connected the grounds and pins 4-7 together on the boards.

would be nice if someone could help me.

@doggoegg

"ESP32S3 Dev Module" and "Nologo ESP32C3 Super Mini"

Please, post the pictures of your above two boards along with SPI connection to allow me running your codes.

I can not understand what you are doing hardware wise, it sounds like you are trying to connect two boards at the same time. Post a photo that clearly shows the wiring connections (may need 4 or 5)

i made a mistake i meen pins 4-7 i just corrected it.
