Hi. Looking for a vendor stocking PCA9901 trainable flasher IC in the U.S. Do you know of a source ?
Hi, I'm currently working on a FRDM-KEAZ128 board. The plan is to then use this mcu on a custom PCB and program it. I looked for some programmers and there seems to be only two (Cyclone MAX and flasher ARM). Both are extremely expensive. Then I found this debugger but I don't know if I can program with it:
Hello all, I was asked by a friend to find a simple flashing LED circuit for his project. I found a cheap kit on ebay, and here is the schematic for it. However, I want to change the LEDs to the SMD type, for their small size, and also change one LED to blue. I have the LEDs, but I was wondering what I nee
Hello, I have an Yaesu FT-3000M installed on my FIAT PALIO 2010 . The problem is that when I turn on car's flasher with the radio in TX the flasher flashes very fast, simply back to RX for flasher back up and running normally. I have checked the cable , connectors and antenna are all OK. Also connected radio's power cable direct to the (...)
Hi guys! I hope you can help me. I have a tiny led flasher, and i want to copy the circuit for a project. This is how it operates: (1) The first time i close the circuit, it starts blinking. (2) The second time i close the circuit it goes from blinking to a steady light. (3) The third time a close the circuit it shuts off. You onl

Hi, Before anyone tries to debug your code, have you tired any basic tests on the oscillator ? Have you done a simple program for just a one second / one minute/ one hour led flasher running from the F676s internal 4mhz oscillator and then on your both your external crystals. I would put money on them working ok. Assume they have the corr
This is another example. There is in Keil\C51\Examples\BLINKY /* BLINKY.C - LED flasher for the Keil MCBx51 Evaluation Board with 80C51 device*/ #include // changed // When you have enabled the option Stop Program Execution with Serial // Interrupt, the Monitor-51 uses the serial interrupt of the UART. // It is t
FWIW, the LM3909 LED flasher/Oscillator IC was intended to maximize LED duration from a 1.5V cell (now old but maybe still available out there). One of the app-circuits was for a booster (not a flasher) that drew only 4mA while feeding the LED with short high-current pulses @ 2kHz (constant to the eye). But I'm sure you might have a brightness trad
if you are a newbie then start learning ne555 based timer. like astable m.v , led flasher. lm324 based comparator. transistor based amplifier. e.t.c look for some old junkie radio, & tv sets. try to understand the components .. study the datasheet & servicemanual
i need just small programming in pic16f54 micro controlor when i give voltage to pic16f54 it should wait 10 to 30 sec (adjustable) then ON/OFF a relay 4 times (ON/OFF time should be adjustable) after 4 time ON/OF it should be stay off thats it simple like a flasher circuit can anybody help me???
so, you don't need a simple flasher.... try this 93439

Hello, I write this code for flasher wave and need to use "pow" function but there is an error says "math_double.c" void main() { int i; TRISB = 0; while(1) { PORTB = 1; Delay_ms(300); for (i = 0; i<=7; i++) { PORTB = (PORTB*2);
We have designed a board for LPC2478. I am using H JTAG to check the board but the board isnt being detected. I get a message that says unable to detect target. But sometimes it does detects in H Server.. but not in H flasher. It pops a message to reduce the TCK speed. If i remove the RTCK pull down resistor (10K), the H Server detects ARM7 ever
Hello, We are doing an smps LED lamp which must flash on and off, possibly in synchrony with a sync signal, -if a sync signal is received. The flashing may also need to be in anti-sync to the sync signal. The lamp should also send out a sync signal itself, and if a sync signal is being received, then it must be in phase with the one received.

Dear Respected Members, I have found couple of topics related flasher On/Off Circuits, they have used 555-time IC. I want to make a simpler circuits with fewer components without an 555 IC that can give me On/Off time = 0.5 secs. Any suggestions ? I have made it with C945 , capacitor and resistor, but ON/OFF time is less then 100ms.
study some of the example software (firmware) used in PIC or other micro-controllers.. understand the code used, this can be either in C or assembly, I think assembly language would be better as its simple, a simple program like a LED flasher would be a suitable program. Also study the datasheet of the micro-controller. Learning assembly language
Dear All Friends Hope lot of people have won the EDA Board logo pen drive, if it stop working you can used uploaded software to get it working back same method can be used for other chip just check out what type of controller it has then Google it with part number you will find flasher software for the controller chip, i have shared a link here
