It was bad soldering due to which my output was not coming. IC was TSSOP package which got misplaced a lil during hot air soldering. Now its working fine when re-soldered. Thank You All.
I have been using ADP5070 DC-to-DC Switching Regulator with Independent Positive and Negative Outputs to convert +5v to +/-15V. Upon testing on the PCB,
Desired Outputs are +15V and -15V on the independent boost and inverting outputs of the ADP5070 ic respectively.
Outputs we are getting upon...
Hello,
I have designed a custom development board for DSP controller. The power circuit (delivering 3.3V to the board) I have used is not working. I am sharing the power supply circuit schematics.
Till now I am thinking that while soldering, the IC get destroyed due to which it is not working...
I have designed two signal conditioning circuits. One is for giving input to ADC and other one is for taking output from DAC. Input to ADC signal conditioning circuit is 0-5V or 0-12V and getting an output from it in range of 0-3.3V. Similarly, DAC signal conditioning circuit is changing voltage...
I am using DSP controller TMS320F28069 to make my own development launchpad Board. I have used the reference of XDS100V2 Jtag Schematics to design my on-board programmer in that development board. I have printed the PCB but when I went to program my controller via on-board Programmer, my code...
Hello
As you said most critical signals (but not all) are active low. It all depends on one's application for real. But generally active low is chosen as when you are having control signals interfaced with micro-controllers,and most controllers have I/O pins high on default. So I guess that...
Hi,
DHT11 has four pins namely DATA LINES,VDD,GND... Data lines are single wire each but in both ways. Refer the datasheet. It clearly says complete data transmission is of 40 bits. So, no analog pins out from DHT11 sensor.
Re: Displaying value on 2 line 4 digit 7 segment code
Hi,
I have analysed your code. According to how you made your code for each character, I found out that it's a Common Anode (Positive) display {As 7-segment LED's are getting ON when you are giving '0'}. Further, you just provided some...
Hi,
To fully analyse the circuit you provided, I need to know what is there connected with those three control terminals.
If it's not possible to provide those details then all I can suggest is that
1. voltage level is not enough at the switching terminal
OR
2. Due to some logic error, LED is...
To Detect the zero crossing of the AC supply, follow the following steps:
1. AC supply needs to be rectified via bridge rectifier. {Take a parallel connection}
2. The pulsating DC which you gonna get after step 1 is also having a zero crossing at same position which we need to detect, is given...
