error printf for uint64_t,...

[TienHuyIoT]

Sample Code:
uint64_t i = 12345678901234;
Serial.begin(115200);
Serial.printf("\r\nTest: %llu", i);

Get:
"Test: lu"

But, i try test with ESP32. I get "Test: 12345678901234". How to solve for esp8266

You could try %lu or even %u?

[TienHuyIoT]

When I try %lu or %u. I got a result as uint32_t.

[Jeroen88]

Then I can't help you, sorry!

%Lu is synonym for %llu and this one neither works (shows 32 bits like %u / %lu).
Is there really a need to show such large numbers ?
