So far, everythinks works fine with the 2 new GIGA. However, one problem came up.
I need the serial communication between both GIGA's.
Connected RX1/TX1 (PIN19,18) at the first GIGA with TX1/RX1 (PIN 18,19) on the secound one. Each GIGA connected via USB at the same PC, IDE 2.3.4. Both have the same example sketch "Communication - MultiSerial". Result: Nothing happend when I put something in the serial Monitor.
ImportanT: As reference, the exact same configuration works fine with two MEGA at the same time.
Thanks in advance for your input.
On GIGA - Serial1 is on pins 0,1
Serial2 is on pins 18 and 19

Thanks KurtE. I connected pins 0,1 and it worked. However, in the documentation it is named TX/RX and pins 18,19 named as TX1/RX1 (the same is printed on the header).
Anyway, it works and we can close the topic.
Been there, they simply reused the same headers as used on the MEGA.
What the difference is, is on the Arduino MEGA the USB Serial object uses a UART to talk to the chip/processor that handles the USB communications, they also then connect those two pins to the header as pins 0 and 1.
The GIGA, like the Leonardo and UNO R4 Minima, ... The USB communications is handled directly by the USB subsystem of the main processor and does not use
up one of the Hardware Serial ports.
The one image on the link I mentioned in first post is about the only clue
you have...
Good luck
Okay and thanks again. Whilst the communication is working now, one final question. Is there any way to upload any sketch via serial ports? This could be an alternativ solution for me, because for the time beeing it seems to be impossible to do that over WiFi with the GIGA R1.
I'm aware this is a new topic,please let me know thoughts.
Sorry, I have no idea...
As you mentioned, probably best for new topic
