Hi,

I'd like to know if it's possible to use a 16x4 LCD display with EasyPic5.
If it is, what kind os LCD should I buy ?

Tks !!!!

Hi Ionut, Thanks for helping!!! I did a research and it’s not a good idea the bootloader for 16F628. Even so far I didn’t understand completely how bootloader works… So I'm trying to understand how to use ICSP. I have a EasyPic5 and I'm thinking to make a cable with the 5 signals (+5, GND, CLK, DATA...

Hi Ionut,

Is it possible to use bootloader with 16F628A?

I never did it before... Could you help me with some tips?

Thanks !!!!

Hi, I developed a specific hardware and software using PIC16F628A and MikroB. Now I’d like to know how I should increment in the hardware for an in circuit programming using a USB cable or any other kind of cheap communication. I think I could do only one hardware for a USB communication and from th...

Hi Raslan, I did... its on the title of the topic... its a 16F628A...

My question is if the code with the counter is OK and when should I use te counter and que should I use the TMR configuration...

Thanks !!!!!

Hi guys! I have a simple question about interruption... I need to use TMR1 like a counter and TMR0 for interruption generation... So I did the following: sub procedure INTERRUPT() timer_count = timer_count +1 if timer_count = 800 then T1CON.0 = 0 INTCON.2 = 0 timer_count = 0 sample_tmp = TMR1reg TMR...

Very nice information !!!!

Well, I'm going to use a BC-338-25 with a base resistor of 470R

I did the following:
Pic leve 1 output (5V) - VBE (0,7V) / IB (10mA) = 430R

Thnaks all !!!!

Hi guys, I sove the problem but its not a general solution... like i need only the bit 0 of the most significant byte i just did this: PORTA.0 = sense_led.0 PORTA.1 = sense_led.1 PORTA.2 = sense_led.2 PORTA.3 = sense_led.3 PORTA.6 = sense_led.4 PORTA.7 = sense_led.5 PORTB.0 = sense_led.6 PORTB.1 = s...

Hi Zan, Its a good idea but I need to send a specific bit from HiByte to a specific pin on the port, not to all port... so I tryed it and doesnt work... :( The problem is that the command PORTB.2 = sense_led.8 send the sense_led.0 bit to PORTB.2... I dont know way but always the program send the bit...

Hi, I'm trying to white to a pin port a specific bit of a word variable but the program didnt reconize what I want... could someone helps me? See pre program: supose the sense_led = %0000000100000000 PORTA.0 = sense_led.0 PORTA.1 = sense_led.1 PORTA.2 = sense_led.2 PORTA.3 = sense_led.3 PORTA.6 = se...

Hi Raslan, I was considering using this configuration but I think when the RA4 goes to level 1 I’ll have no voltage on transistor base, so I’1l need a pull-up. If I use a resistor connected to 5V for a pull-up, the transistor will not close at all. My load is a 12V relay and using this configuration...

Hi Raslan,

Now I'm confused... :)

Could I use a 10K pull-up resistor connected to 12V on RA4 or not ?

Thanks !!!

Hi Arcom,

Thanks for the answers...

I just found a voltage specification for RA4:

Voltage on MCLR and RA4 with respect to VSS ...............-0.3 to +14V

Thanks !!!!

Hi guys, I have 2 questions about PIC-16F628A hardware... 1) I read on data sheer the following: Peripheral Features - High current sink/source for direct LED drive Is it means I need no resistor to limit current? Could I connect the led direct to an output port? 2) RA4 is an open drain output. Coul...

Hi,

I'm trying to use ICD debug with a 16F628A but i have a warning that this PIC does not support ICD debug... Is it right or i'm doing something wrong?

Could you help me ?
