Hello,
I'm writting Labview code to control via the PMBUS the UDC90120 controller. I need help with the correct math syntax on how to calculate in hex value the Duty Cycle, Frequency and Phase when I add a fraction to the integer. For example when the duty cycle is 50.0%, Freq is 5.00 MHz and phase is 0.0 the correct hex value are as follows;
PWM_CONFIG_0 [MFR 17,0xE1]: wrote Duty Cycle: 50.0 %; Frequency: 5.00 MHz; Phase: 0.0 deg [0x0032004C4B400000] to RAM
When the duty cycle is 50.1%, Freq is 5.01 MHz and phase is 0.1 the correct hex value are as follows;
PWM_CONFIG_0 [MFR 17,0xE1]: wrote Duty Cycle: 50.1 %; Frequency: 5.01 MHz; Phase: 0.1 deg [0xE322004C72509B33] to RAM
Can you send me a breakdown of the math on how to calculate the decimal digit as shown above?
I'm stuck on this issue and cannot continue with my tests.
Thanks,
Norberto
