Hello, I'm working on code that sends information by SPI from Raspberry Pi to Arduino. This code sends characters to Arduino and everything works very well but I need to read the binary code of SPI connection and show on a serial port before it converts to characters.
How can I change the Arduino code to read bits of spi connection (before convert)? In fact, in the new project, I need to send the binary code by Raspberry Pi and Arduino to show by LEDs.
Thanks.
Not sure if this is what your looking for. You will need to loop through buf and print each individual byte.
Something like below
void loop (void)
{
if (process_it)
{
buf [pos] = 0;
for(uint8_t cnt=0;cnt<pos;cnt++)
{
Serial.print(buf[cnt], BIN);
Serial.print(" ");
}
Serial.println();
pos = 0;
process_it = false;
} // end of flag set
} // end of loop
Please be aware that leading zeroes are omitted.
PS
Note that any data is binary.
