    [PIC] Alarm clock and temperature using PIC16f877a - code ASM- 6 led 7seg

    Hi Ndnhatminh I am battlling to see how you have connected up your switches. assuming your switches are on port B as per your software. You have set RB0 as your interupt as per intcon bit 4. then immediately after that you set bit 6 and 7 and clear bit 4 ( refer to RB0 interrupt and timer 1...

    [PIC] Alarm clock and temperature using PIC16f877a - code ASM- 6 led 7seg

    Hi Ndnhatminh You have made it very difficult to read your program to see what you are doing I dont understand vietnamese. could you translate your registers to english. Could you post your schematic here as a Jpeg so I can look at it. We could then go through it step by step so I can help you

    NiMh charger problem or bettery ?

    Hi AudioGuru Thanks for your comments I have indeed used this circuit many times to charge Ni-mH batteries. It was merely a suggestion for a method that I have used many times without problems. Is this forum not here for people who wish to design or make things for themselves as opposed to...

    NiMh charger problem or bettery ?

    There are a number of reasons why your charger is not charging these batteries my advice is to build yourself a charger such as this one : https://obrazki.elektroda.pl/6544102100_1428224733.gif Part Description R1 56kΩ ¼W, 5% resistor R2 27kΩ ¼W, 5% resistor R3 22kΩ ¼W, 5% resistor R4 47kΩ ¼W...

    Sony CFD-S47L auxiliary input

    From your Schematic it is clear to me that you are overdriving the inputs of the TA 2068N. Typically a tape head delivers a signal of about 2 milivolts this would then be amplified a small amount by the volume sound control IC. A aux input is typical in the region of 1volt this is why the sound...

    [PIC] DSPIC33fj_Understanding disassembly Hex to assembly.

    So I have worked on it some more and found that by multiplying OF x 2 we get 1E which happens to be where register W15 sits. Still trying to figure out where the #2096 comes from.

    [PIC] Programming of DHT11 sensor

    Looking at the info supplied by the manufacturer 1) The microcontroller must initiate communication with the DHT11 maintaining the data line low state for at least 18 ms. on pin 2 of the DTH11 2) DHT11 then sends a response with a low pulse 80 uS and then left to "float" the data line for...

    [PIC] DSPIC33fj_Understanding disassembly Hex to assembly.

    Could someone possibly help me understand how to disassemble hex code to assembly for a dspic33fj. from what I understand the hex code is intel inhx32 format. so i took a snippet of hex code and tried to decode it via a excel spreadsheet. here's where i cannot get to the same code as mikro C...

    NiMh charger problem or bettery ?

    suspect the batteries they should not go below 1 volt per cell. Nimh have a shorter shelf life than Nicad therefore if they have been in storage for a while they will have gone below the charging threshold of your charger
