    [SOLVED] ATMega8A ADC Not Working

    Instead of using PORTD = (adc_rd >> 8); use: PORTD = (adc_rd >> 2); ADC has 10-bit resolution. By shifting 8 bits, you will only be left with 2 bits.

    Using IR2110, HO does not switch on

    It might be possible. I am still trying to find out the issue. Below is the complete circuit and the waveforms. IR2110 input waveforms IR2110 output waveforms g2 wave is not shown. It is exactly the complement of g1. Do you suggest using TLP250 as isolated gate driver?

    LCD and pic not comunication

    ^ That was just an example. In either case, they have to select the proper configuration bits, otherwise mikroC will not generate proper timing signals for the LCD.

    LCD and pic not comunication

    Hello LCD problem normally occurs when you forget to configure the clock frequency. Use the OSCCON or equivalent register at the start of your main() to set the proper clock source. Then from the Project menu, select Edit Project. It will open the configurations. From Oscillator Selection...

    Using IR2110, HO does not switch on

    Thank you for the reply. Yes, I am connecting VDD to the logic supply voltage. The mosfets are working on the hardware, and also in the simulation. I am now facing a different problem related to interaction between Q4 and Q1. They seem to cause some sort of a short in the circuit when both of...

    Using IR2110, HO does not switch on

    Hi Klaus Thank you for the reply. For some reason, adding a NOT gate seems to work in the simulation but direct input from the signal generator does not work. I will have to test it once again on the actual hardware tomorrow. In my case, the inputs are coming from a microcontroller. VDD is...

    Using IR2110, HO does not switch on

    HIN and LIN are 5 Volts. VDD is actually for IR2110. Proteus does not have IR2110 model and I am just using IR2112 for simulation purpose.

    Using IR2110, HO does not switch on

    I am working on a multi-level invertor and using IR2110 for gate drive but I am facing a problem with the High side output. It does not seem to switch on. Please see the attached Proteus design for the basic test setup. Is there anything I am missing in the connections? I am trying to follow...

    Can anybody help me how to write a program to monitor a port pin in PIC 16F628A

    Are you using assembly? Use the BTFSC to check the input port pin and assign the same bit to the output pin. For example: PIN_LOW: BTFSS PORTC,0 ; assuming PortC.0 is the input GOTO PIN_LOW BSF PORTC,7 ; assuming PortC.7 is the output PIN_HIGH: BTFSC PORTC,0 GOTO PIN_HIGH BCF PORTC,7 GOTO...

    applying equations on ADC samples in mikroC

    If you are taking V, Itotal and Ifundamental as analog inputs, then you can easily apply those equations directly in mikroC. Its all straight forward. unsigned int V, Itotal, Ifund; unsigned long Swith_harmonic; double Iharmonic, Qharmonic, distAngle, TrueActPwr ; V = ADC_Read(channel_V); //...

    JPEG Face Detection for PIC32

    Hi all, I am looking for some help to develop a face detection and recognition program on PIC32. I tried using the OV9650 camera but it did not work so now I am using the µCAM-TTL from 4D systems. The problem is, the PIC has very limited RAM and using RAW images seems very difficult as the...

    PCLK out of OV9650 Camera Module

    The PIC is properly configured for input. And I also tried checking the PCLK directly on oscilloscope without connecting the PIC but it is still the same. Tried connecting pull-down resistor, pull-up resistor, series resistor but still the same. Connecting high value of series resistance is...

    PCLK out of OV9650 Camera Module

    Hi all, I am facing a problem while trying to interface the OV9650 camera module with PIC32. The PCLK pin of the camera module is giving out unexpected output. The difference between the high level and low level of the PCLK clock is so low that the microcontroller cannot distinguish between...
