Hello all, I working on project that ons the relay when 3 phases are on and offs the relay when 1 or 2 or all 3 phases are faulty. I need direct 3 phase connectins to pic 16f628 no tarnsformers , optocouplers etc. I attached one image that tells when 3 phases are available then what happens. See image bellow124689 Can i u
i want to build on off programable switch using pjc when i search on net then this project is find. link of project= but the problem is this code is only for one cycle of relay on and off operation ... i need relay on off on off after given time un
in 16f628a their was no registers to set, just initialized UART to same baudrate. What about stop/star bits number of bits etc Below is the code to initialize the 16f628 to 8 bits no parity one stop bit. Tested and working. bsf STATUS,RP0 ;Bank 1 movlw 24H ;High speed async 8 bit movwf TXSTA movlw BDRATE ;Load baud rat
a single "old" pic like 16f84 or 16f628 and a small program inside and you're done with every situation you want even 2 digits CA and 2 digits CC are possible this way !
talking electronics have a good display using pic has six buttons for up,down,left,right,store and delete.check it out. www.talkingelectronics.com.or just google talking electronics.com.all the best.
hello all, I have a new problem here. I'm still learning C for pic (xc8 compiler) and as a beginner project i'm doing a thermometer with the popular ds18b20 and a pic16f628 i had lying around. My program does behave good when it is allowed to run but while i was playing with pointers, structures, arrays etc. to return more than one value (...)
Hi, I have recently finished to upgrade my old dish antenna positioning system by adding to it a homebuilt positioner interface, based on the pic 16f628 microcontroler. It's working fine :grin: If enyone wants to try it out , and need further descriptions, hex, details........ contact me :wink:
hello Even with a pic16F84, or 16f628 or 18F252 you can use an external clock for 16F8x use HS osc for configuration ( but in fact you don't use the internam pic Oscillator ! ) and connect output of External oscillator to the pin OSC1/ClkIN ISC2/Clkout keept unused i used this kind of oscillateur EPSON 25MHz on 16F84 for DDS (...)
hello to all i want any one to help he to build projest using the pic 16f628 to connect between the smart card and the reciver as this the smart card connect with the reciver with 5 pin 1 = vcc 2 = vdd 3 = reset 4 = clock 5 = i/o i want to connect the pic between the smart card and the reciver to change the answer from the card when (...)
I found the pic 16F877A and 16F877 some what fragile. I have damaged several of these while programming on the picSTART plus programmer. Whereas I never had such problems with 16F648A/16f628, 16F690 or the 18F series. I think the 877 series is more susceptible to damage than the others. Probably design fault or something makes this happen.
check this Nigel's pic Tutorial Page Nigel tut1_2 with 16f628A
Yes, comparators may work similarly if you properly configure the 16f628 Regarding the PWM, you must write some code to implement an inverter similar to SG3524, but have in mind that pic's PWMs outputs are CMOS and have no drivers to handle power
I want to use a 16f628 to send serial data. I have written the code below, but there is no output on RB2.

Hi , could you help me please to understand the assembly code of this LCD tachometer with pic 16f628 for example I don't undersand the use of blades and how it works ?
Hi all, my name is Kostas and I'm facing a problem with my thesis and I need help about solving it. Well the problem that I'm facing has tdo with the communication of a pic microcontroler ( 16f628 ) and a gsm modem (Simens T35i terminal). I can't send or receive commands between those two devices. For example, I'm trying to send the "AT" comm
is it possible to use adc 0804 to interfaced in 16f628 to serve as external adc of 628,,cos 628 don't have,,, yes, it is possible.
Hi...why dont u try some other pics which have more features as well as ports..such as pic16F876A which have inbuilt ADC... Interfacing external ADC(0808/04) with 16f628 will require almost 8 pins or more...but, i guess the remaining pins wont be sufficient to interface with Nokia 3310...since normal 16x2 LCDs require a minimum 7 pins...Regards.
Hi, I'm trying to built a program for pic 16f628 in order to communicate with TC35i modem, but I'm having some problems. 1. I don't know how to read parts of incoming messages. For examble, I used the hyperterminal to learn which at commands I'll have to use in my program. When I'm sending this command: AT+CMGL="ALL" I get: AT+CMG

i suggest tou you to Use picbasic,Proton and a smaller pic,like a 16f or 18f temp sensor : ds18s20 bluetooth : rn-41,roving network pic :pic18F1220 or 16f628 an exemple here for the motor driver SN754410 in basic
