    [SOLVED] PDLC Smart glass power supply

    Thank you for replay, Can I use triac based supply(dimmer, some module available for Adriano, I am familiarly with this ). I am asking this because it is given in specification that it require sine wave. So inverter circuit is necessary or I can use triac based dimmer?? And what exactly used in...

    dac0800 not working properly

    I also give fix value by putting "PORTD=254" or "PORTD=128" but on 254 it give full output (this is correct) but on 128 it give 0.7V. So and DSO also show correct voltage level on microcontroller port pins and there is no voltage drop portd pin.Please see the reference voltage pin. As I told I...

    dac0800 not working properly

    HI, I am working on dac 0800 interfaced with atmega32. But when I run a simple counter then dac 0800 not give expected output. connection between microcontroller and dac is correct and digital output of microcontroller is also correct. And I am getting all supply properly. Only at +Vref of dac...

    [SOLVED] [moved] problem in using st7565 glad

    Re: [moved] probleum in using st7565 glcd Thanks for replay, I already attach link of lib and only difference in font size and I using ST7565 in SPI mode. If you can suggest good lib or reference. Many time I face this problem and I have to use different font like 8X8, 5X7 etc. for my application.
