    7Inch FHD Monitor on Raspberry PI

    Hi, I'm using repetier server on raspberry Pi 3. And I interfaced 7inch FHD Monitor(1920*1080)(Waveshare Display). I was getting the application output on the display. But all icon buttons are very small, which is very difficult to access on the touchscreen. I want to scale up this icon button...

    To develop 3D printer in PIC controller

    Thanks andre, I want to make a 3D printers for the fabrication of the plastic parts, i found that in few videos that marlin firmware with AT2560 is working fine, i want to develop the same with our PIC(8/16bit) or renesas controller(RF series). and moreover the AT2560 also a 8bit controller. can...

    To develop 3D printer in PIC controller

    Thanks for your reply, I know the difference between Controller and processor. i asking for how to process a G code comments in PIC controllers like what they did in ATMEGA. is there any tutorials for the executing G_Code comments? - - - Updated - - - Hi KlausST, Basically we can develop...

    To develop 3D printer in PIC controller

    Hi all, I found that, 3d printers are developed in atmega controller by the Marlin Software. Can we develop the printer by the help of PIC controllers or any other controllers than atmega/raspi. Please suggest any possible way of doing. Thanks,

    Lead Acid Battery Charging Circuit for 24V

    Thanks Vbase, Ok. for various input supply, that vref 2.3v will be same or it will be different for different supplies. - - - Updated - - - Thanks Klaus, I couldnt get that over charge indication to low. I monitoring the battery voltage for every hour, it has been increasing by 0.4V/hr. it...

    Renesas E1 Emultaor is not detecting

    I have been working in the renesas controller and i have a renesas E1 serier emulator. few months before i have worked in this emulator, at that time it is worked fine. but now its not detecting, some warning error showing in the device manager. when i try to update the driver, it saying as all...

    Wireless Communication

    --> define "huge number". Is it 1000, is it a million? ====> data's around 10,000bytes --> what microcontroller interface do you want to use? ====> yet to decide after selecting the protocol. Mostly Renesas RX62N group. --> only one direction, no receive, no handshaking? ====? Tx - 10,000 bytes...

    Wireless Communication

    Hi all, My requirement is to send the huge number data's within a second at longest distance(500mtr to 1Km) from the micro controller. Could you suggest which communication protocol is best to use and be very easy to handle.

    How to use PTC with coil

    And one more point for you, i have to place the PTC over the coil to sense its temp. If it is over heat, the circuit has to open, when its come to normal, the circuit has to close.

    How to use PTC with coil

    I have attached the 12V solenoid datasheet, it is similar to 24V solenoid, voltage only the difference. - - - Updated - - - see my current flow is 650mA only, PTC has the 900mA current rating. Then how it will get heat. One thing i having the doubt, wether the PTC will work upto 900mA or it...

    How to use PTC with coil

    If anything happened in the board or some short happened means, the coil tends to activate. On that time how can i prevent the circuit to open? is there any other way to gets open? Important thing is, if the coil gets 24V Continously means, it tends to tremendous heat. Please suggest any other...
