| Thank you, Mr.Bogdan and have good week.  |

| Hello Sir Bogdan, I think that I find the problem: If the power is over 5.7 there is no problem, but if the power is 5.6v or less, the R19 Ds18s20 resistor need to be smaller than 4.k7. (3k3) and work fine. By the way, do you send me the this program flowchart? Tanks a lot Rui   Response: Hi Rui, I was in the mountains for a while, sorry for the late response. My circuit uses a 5V voltage regulator and the 4k7 resistor work well with it. Is it possible that you maybe use a longer cable? I don't know.. but it's great that you found a solution for you. I don't have a flowchart for this project and will take a while until I'll have something. Cheers, Bogdan |

| ello Sir Bogdan, I was looking a thermometer using PIC16F628A and DS18S20, when a find your beautiful project """dual_single_therm_wI I built it using the ".._CC_S20.hex" to load PIC16F628a, and DS18S20P. when it is in temperature mode, the display show fixed "127C". I changed PIC and DS18S20 two times and the problem maintain. I try load the "..._CC_B20.hex" for teste propose, and the display show fixed " 5oC" . Can you help me? Rega... |

| Hello Sir, Always have the honour to seek help from you. Please send me 3 digit dc voltmeter/ panelmeter project if you have. Thank you |

| Hi Dear Sir, Many thanks for replying me back. Sir I have used PIC16F84A and DS18B20 for my clock. Additionally, I have used a piece each of ULN2003 and UDN2981A arrays because I have used slightly bigger 7-segments for my clock. It is working nicely. Now sir please send me .hex file for 12 hours format of the same clock so that even little kids can read the time. Another problem sir, when i used PIC16F628A for the same clock then the clock lost about 4 minutes/24 hours. Response: Answered via email. |

| Hello my dear brother, Your clock project is great and i have built one for me. It looks awesome.But my little kids did have problem for 24 hrs format. Can you send me code for 12 hrs format of the same clock so that even children can easily read the time. However it is a great effort from your side and please send me some other PIC projects. Thanks and keep smiling. Response: Hi Rana, Thank you for your feedback! Please tell me what PIC/sensor did you used for your clock. I can then make a new hex for you. Thanks, Bogdan |

I admire your work ... really its art.I'm just finishing technical school for computing technician and my finishing work is Digital Clock but with ATMEL -.- 89c51 because we only have programmators for AT ... so I'm asking you if this clock,program could work with atmel instead of pic (8051 family)without big modifications (regarding to CISC>RISC architecture and other differences),if so it's possible could you point out what modifications there would be?Thanks in advance...  Response: Hi Domagoj, Thank you for your appreciation!  If the clock's code would be C you could have transferred into atmel, still no easy job here. My opinion is that you could not convert PIC ASM into atmel's architecture. I googled aroung but did not find a converter from PIC ASM to atmel ASM, not even from PIC ASM to C. I found others who wanted same think but did not received positive answers. Architecture and language make both important differences between PIC and AVR. So I think what you want is not doable.

| l-am facut cu elevii la scoala cu PIC16F628A si cuPIC16F84 in varianta big cu leduri albe insa face tot asa crezand ca am gresit schema l-am facut de 10 ori dar tot asa face daca poti sa ma ajuti iti multumesc mult Response: Salut Virgil, Imi poti spune mai multe? Ce pic si senzor ai folosit? Ai facut varianta cu 14leduri/segment (5V) sau cea cu 6 leduri/segment(12V)? Derularea meniului mi-ar spune la prima vedere ca butonul SET e tot timpul apasat. Eventual sa verifici daca rezistentele de la acest buton sunt OK, poate ca rezistenta R16 e stricata. Scrie-mi te rog pr borca_bn@yahoo.com Mersi, Bogdan |

| in varianta mini merge perfect. insa in varianta big imi deruleaza meniul de setari. |

| Many thanks again for your great clock/temperature circuit/firmware, I love it. I have used it again for my Aurora Mini-Clock. It uses a common anode display and PIC16F628. I have made it auto-dimming by feeding the 4 pnp transistors with a variable 2.5 to 5v supply from a LM317 adjustable voltage regulator with an LDR. You can see it here: youtube.com/watch?v=AeMk Steven Response: Hi Steven, Nice one Thank you for feedback! Glad you like the clock. And your Aurora is awesome!  Cheers, Bogdan |
