Resolved! What is the sprintf format for a uint64_t? %llu prints as "lu" (Just the characters, no number) Is there something special library I have to turn on? Like with floats?

Here is the code: if (constx8 == 0) // calculate constants one time. { uint64_t num = (((uint64_t)(((uint32_t)(R21 + R22))) * VREFINT_CAL_VREF) * (*VREFINT_CAL_ADDR)) << 8; uint32_t denom = (uint32_t)4095 * R22; constx8 = (uint32_t)(num / deno...
