PIC16F628A + DS18B20 + 7 segment [MikroC] - Electronics Forum …
Sep 8, 2010 · Hello people, After I set up the LCD temperature display, I want to show temperature on the digits (7 segments) in this method (00,0C) with 0,1 degree Celsius rezolution . I am using the MCU P16F628A, temperature sensor DS18B20 and 4 digit (7 segment) with common cathode. Language used is...
Pic16f628a projects | Electronics Forum (Circuits, Projects and ...
May 26, 2009. #1. Hey guys i was wondering what projects i could do using the pic16f628a. Ive already built a 3x3x3 led cube using be80be's schematic and hex file..ive also nuilt an 8 channel pwm led chaser from the picprojects website. So i was wondering if anyone could provide links to any websites that have any other projects that use this pic.
PIC16F628A PWM for LED Chaser | Electronics Forum (Circuits, …
May 30, 2020 · LED is at step 0, another is at step 16, another at step 32 and so on. The step counter is added to the constant offset, so the LED brightnesses "rotate" through the step buffer. After every PWM count increment, a function (subroutine) is called for each LED offset, to get the step and from that the PWM on/off decision.
Timer1 with PIC16F628a and 32.768KHz Crystal
Apr 6, 2014 · If you write to the counter then you'll probably introduce errors, I've used a watch xtal on timer1 a few times, one project has a cursor led that flashes every second, I just count I think bit 15 of timer1, it toggles at 2hz, every 2 cycles is one second, you just need to use up a register location for a counter, then your led will keep very accurate sync with the clock on …
LCD display pic16F628A | Electronics Forum (Circuits, Projects and ...
Jan 26, 2010. #4. You can interface a 16x2 LCD to a PIC16F628A using just 6 pins of the uc. Then you will have 10 more digital I/O pins to work with. If you want to display different messages on the same LCD for different input conditions, I don't think you need an multiplexer like 74LS151. .
ADC with PIC 16f628A - Electronics Forum (Circuits, Projects and ...
Nov 30, 2006 · I use external D2A and a comparator from 16F628. I connect the output of D2A to RA2 of 16F628 and Analog voltage to RA1. Then I increase D2A value 0 to 255. In each step I check Bit 6 of CMCOM register (Later I say "Result"). If Result is 0 then increase the reference.
Difference between a PIC16F627 and PIC16F628A | Electronics …
Dec 2, 2005 · Hi all, I have found a really strange issue. I have this LCD clock written in ASM, and that runs fine on a PIC16F627. If I program a 16F628A with the same code, I'll get a very weird thing, and that is that the Hour display en minute display is written as follows: 00h = 80 12h = 92...
How to generate Beep sounds/Piezo using PIC16F628A
Sep 3, 2010 · May anyone expert with PIC help me on PIC16F628A? The attached code is a 8 - leds chaser code with PWM, with time delay RELAY. Port RA2 will send output/high to relay after delay approx 4 mins 30 secs. I willing to add piezo on Port RA3, so that when RELAY ON(RA2 is high) the piezo will beep 3 times. Please help me!!!!
Pic16f628 replacement. - Electronics Forum (Circuits, Projects and ...
Oct 28, 2013 · Might be a common question. What would be a suitable replacement for a pic16f628, its been out a while now and I spose microchip will be saying if not allready that the device is obsolete. I use timer 0, 1 and 2, the pwm module, the uart and external clock for tmr1.
Pic16f628a - Ra4 Open Drain Output | Electronics Forum (Circuits ...
Jun 17, 2008 · Forgot to mention, the output RA4 Open Drain pin on a PIC16F628A already is implemented to do the 'invert' of the logic, so operates in TRUE logic. The only thing to be aware of here, is that when the PIC first fire's up, (and especially if you are using the Start Up Delay), the output is ON until the first initialisation / drive to PORTA ...
