Kit Laser distance meter ep3c5e and stm32f407 50M

sorry for my bad English.

I corrected the algorithm. The phase measurement 45 MHz and 3 MHz at a distance of 30 meters 1 step 20mm 1500 points. 3 MHz for calculating the multiplier i.ph_long = ph45Mhz+360*i The source code below how to do this correctly?

	if ((phase3Mhz_deg > 33000) || (phase3Mhz_deg < 300)) {
