You can set a reminder directly at other timezone and app will automatically manage that for your local time. App supported by a widget to perform all these conversions even when the phone is locked.

"Someone asking for meeting at 3 PM Los Angeles time, wonder what would be local time for you"?Ĭustom converter tool to quickly convert all these times for you, fix meeting quickly, and save time. "7 PM in Perth, what time it would be in London at 10:15 PM"? "6:15 AM in Tokyo, what time it would be in New York"? You can also track the time from the widget when the phone is locked. You can add timezone around the world that you most commonly use and can see the time in analog and digital format.Įasily convert multiple time zones at a glance. This may suggest stronger clues to underlying analog source in jitter.*** Most elegant and simple clock app with timezone converter, reminder and widget support ***Įffortlessly track the time of different cities and timezones.

If possible, change FOUT software settings to change and look for stability changes.How does it change when choosing 4MHz x4 and 16MHz x4?.CM noise immunity? Does earth grounded make a difference?.Review design for causes of hardware or software induced FM. Coincidentally or not this is a divide by 4 output. This Clock controlled by PLL VCO control noise is is showing excessive FM frequency deviation (25%), which is why only trigger edge is stable. Thank you for any help and insight to this problem.Įxcessive FM noise 25% deviation using x4 then /4 frequency conversion 8MHz ref in 32MHz x4 multiplier in PLL then /4 fout shown in scope at 8MHz with frequency jitter on all edges except trigger edge. Should I be thinking about going to a crystal to improve stability? Would the configuration bits set to INTIO7 for monitoring the CLKOUT line affect this? Is the internal clock of the PIC18F2620 really that unstable, or should I be looking for something else as the cause? I've read all of the errata datasheets from Microchip, but the internal clock is not listed as having errors. #pragma config CCP2MX = PORTC // ECCP2/P2A is multiplexed with RC1 #pragma config LVP = OFF // Single-Supply ICSP enabled #pragma config MCLRE = ON // MCLR pin enabled RE3 input pin disabled #pragma config LPT1OSC = ON // Timer1 configured for low-power operation #pragma config STVREN = ON // Stack full/underflow will cause Reset #pragma config PBADEN = OFF // PORTB pins are configured as digital I/O on Reset #pragma config XINST = OFF // Extended Instruction set disabled #pragma config BOREN = OFF // Brown-out Reset disabled in hardware and software #pragma config PWRT = ON // Power-up Timer Enable bit: enabled #pragma config IESO = OFF // Oscillator Switchover mode disabled #pragma config FCMEN = OFF // Fail-Safe Clock Monitor = OFF. #pragma config WDT = OFF // WDT disabled (control is placed on the SWDTEN bit) #pragma config OSC = INTIO67 // Internal osc, port function on RA6 and RA7. My configuration bit settings are as follows: #pragma config OSC = INTIO7 // Internal osc, CLKOUT on RA6, port function on RA7. OSCTUNEbits.PLLEN = 1 // then PLL Enabled (8Mhz x 4 = 32 MHz). While (OSCCONbits.IOFS = 0) // Wait until INTOSC is stable. OSCCONbits.SCS0 = 0 // Set system clock to use.

I am using the following code to set the oscillator: static void OSC_Init(void) I used auto-store to capture/overlay many cycle on this trace display. The trace below shows jitter on the clock unlike what I've seen with other PIC18Fs. FOSC/4 is output on pin RA6/CLKOUT to a logic analyzer.

I am set up to use the internal clock at 8Mhz and and PLL to get FOSC to 32MHz. I have a circuit board that uses the PIC18F2620 SOIC device.
