Hello, somebody help me please?

Below is my example code.

uint64_t tempVal  = 315989888600;
chprintf(chp1, "\t tempVal : %d %03d\r\n", (tempVal / 1000), (tempVal % 1000));
uint64_t tempVal2 = tempVal % 1000;
chprintf(chp1, "\t tempVal2: %03d\r\n", tempVal2);

And I got console log like below

Code: Select all

tempVal : 315989888 000
tempVal2: 600

I was expecting
tempVal : 315989888 600
but, got
tempVal : 315989888 000

What am I doing wrong?

Hi,

Do not pass uint64_t to chprintf(), cast it to uin32_t or assign values to 32 bits variables beforehand.
