Re: problem using 64-bit Integer type in RTOS SDK

Thanks buddy!
That's other issue that caused the mess in my value on 64bit integer.
At least I can isolate this from the issue.....

in RTOS, 64-bit integer is not support by "printf", but the 64-bit integer type really works well, you can try it like this:

Code:

int64_t a = 0xF0F0F0F0F0F0F0F0;
printf("%d.%d\n", (int32_t)(a/4294967296), (int32_t)(a%4294967296));

problem using 64-bit Integer type in RTOS SDK

2016-06-08T15:45:48+08:00

Recently I'm doing my development on ESP8266, using RTOS version 1.4.0.
RTOS version seems like couldn't the 64 bit integer types, is that true?

I tried printf/os_printf the value for int64_t data type, it will not display for any value more that 32-bit.
I've tried using NONOS SDK version 1.5.3, os_printf having no issue for the int64_t type.

Any further info on this?
Any fixes for the 64-bit integer value in RTOS SDK?
