    Identify the manufacture of EK117 IC and finding replacement.

    maybe the manufacturer does not exist any more. but it look like a sail ship but go nuts... Semiconductor Logos the other loks like russian or ohter language. If you are going to build a new Hardware don't take old mistake from old Hardware. but build it with new technology. it can be an FPGA or...

    [SOLVED] Pic18 controller interrupt

    https://ww1.microchip.com/downloads/en/DeviceDoc/31008a.pdf I use the cx8 compilor so it may be different. T0CON =0x87; //TMR0ON=1; T08BIT=0; T0CS=0; T0SE=0; PSA=0; T0PS2:T0PS0=111; INTCON=0xe0;//GIE/GIEH=1 PEIE/GIEL=1 TMR0IE=1 00 TMR0IF=0 00...

    [SOLVED] Pic18 controller interrupt

    Interupt is Hardware flags, when an Hardware signal has make an event or overfloat, that rice a Hardware flag bit. that the ISR read, and when it read this flag it will run the ISR.

    Identifying a diode and obtaining a compatible replacement.

    I don't think the diode is changing for juncboi and that I reply to. only Modifikation is the Current Mod. You see it the same number. I don't Care if you don't see it.

    Programming Atmel CPLDs with VHDL

    thanks I hope it will work om Win10. I don't want to make a virtual machine to get it to work. I find some eclipse plugin. but many comment write that there is many problem with the plugin.

    Programming Atmel CPLDs with VHDL

    what do you program the Coolrunner II I can see xilinx discontinue the support to the Coolrunner and many more. in the new xilinx version af Webpack free version they only support 6 and 7 series vertex and spartan and one more. this is long time sins I have worked with the dev. board and the...

    [PIC] How do I use Float in xc8 compilor ?

    I use the sprintf funktion not printf, I like to add it to an string array to chop the Ascii in to the display write loop.

    [PIC] How do I use Float in xc8 compilor ?

    what does the const do ? xenos horace1: yes the float works also in practice, but after some time it stops completely and the display just just blink with the cursor, after some time. If I do not use float , it works fine, but then I can not show the volt with decimal, so something happens...

    [PIC] How do I use Float in xc8 compilor ?

    the code works fine with out float to show the int number of the ADC, but when I want to use float it works for a little bit time, and then Crash the Program and the micro P stop. the code print the voltage i Volt, with to decimal after. on a 4 x 20 ascii Display. and have hit the wall :bang: to...

    Cascade amplifier: producing wrong frequency at second stage

    A_bw is where the A is almost 1, it says typical 150Mhz and max 300Mhz, and yes I think of the opamp datasheet with A_bw. but see the datasheet it is 150Mhz. but I will never use only use it in LF, because it is a noise transistor. some like BF199
