Hi,
I am designing a circuit in that i need 1:1 and fly-back transformers at low frequency(0-100khz) and high temperature . can anyone help me with these?
I am looking for voltage being handled arround 12v, if possible at 175-200°C, with same voltage isolation.
I need fly-back transformer to...
Hi all,
I want to design low frequency voltage controlled oscillator. My frequency range should be arround 1 KHz to 500 KHz. Can anyone suggest which way is best to achieve this because i have seen many design circuits but all are little bit high in output frequency.
Thanks.
Hi,
I would like to design analog circuit that will detect signal from pH electrode senor and sent it to micro controller.
I need analog circuit which process sensor electrode signal into ADC, from ADC to micro controller.
I am thinking about Instrumentation amplifier to get low voltage dc...
Hi,
I am looking for equivalent voltage controlled oscillator of XR-2209. If possible at 200°C(high temp).
I am looking for equivalent of INA116 at 200°C.
Regards.
Hi everyone,
I am trying to implement CAN communication on this microcontroller SM470R1B1M-HT(https://www.ti.com/lit/ds/symlink/sm470r1b1m-ht.pdf).
I am new to can communication. I had gone through several CAN meterials as well as user guide for this controller which is...
Hi all,
I have some basic doubts in ADC conversion. I am using AD7798 ADC. I am reading ADC values using AT90USB1287 micro controller using SPI communication. I am able to read ADC values perfectly but i have some doubts.
I had gone through the datasheet several times. I am setting...
Hi,
I have small doubt about micro controller functioning. I am using at90usb1287 controller and i am communicating with PC using USB communication. Will microcontroller works after lost USB connection to PC. Will timers work after USB connection lost?
How to know USB connection lost?
Hi,
I am programming AT90usb1287 controller via USB communication. The device is working perfectly and i am able to sent and receive data from PC.
Is there any way that i can check USB connection is lost or not using programming? I am planning to stop one...
Is Watch Dog Timer enabled?
I am trying to enable and reset the controller and disable WDT in the same command. Is it possible? I have looked into the fuse bits about watchdog enabled or not i didn't find anything about.
Hi,
I am trying to reset atmega32a programmatically. It can be done with watchdog timer. In my case i am trying to reset the timer when i send some command from PC.
I have written code like this for that function.
case(RESET):
#asm("CLI"); //Disable global...
Hi,
I am trying to implement PI control algorithm in c#. I found some help in internet and i understand the formula how to use. I have measured value(PV)= 20 °C and set point (SP)= 80°C; I would like to update every 2 sec in time.
I found this code...
Hi,
i have attached all components connected to switch and as well as clear image of circuit than previous attachment.
