I have found the problem, This is Paging issue. GOTO and CALL can not jump more than 11 bits that is 2kword long.So in PIC16Fxxx we have PCLATH register to switch into 4 PAGEs of 8kword memory. It has to generate and apply by compiler before any GOTO AND CALL and it will ( I checked ASM code ) BUT i...

I have same issue with pic16f877a .
How to solve it?
Sould i seperate my code to small sub procedures and call them one by one insted of a big code or what we can do?

Hello, The problem here is that the size one of your functions is too big that it cannot be successfully fitted into a single page of PIC16F877A. The page limit is 2K and your function alone was 1859 addresses long. Because it calls other procedures on other pages, PCLATH has to be set in order for...

Hi, I am trying to write a code on PIC16F877A . My code works if size of code is less than 1924 bytes which is 23% of total ROM, but if i add a small code like i=1 compiler makes my code 1986 bytes (24%) and my code works wrongly randomly reset or variable changes randomly !!!!!! Also I realized tha...

I need to have code to send a text to sub procedure like this:

Send_out("Hello World")

How to do it in correct way?

If the controller does a reset then something is wrong with the circuit. Try a baud rate of 9600. As written it must not make a reset because then something is wrong with the circuit. Thanks for participation. 9600 BUAD rate make it worse! Even I can remember that on 1st project I ran simulator on ...

Hi, I have this problem in two projects both codes are so similar. I have TMR1 interrupt each 100ms and also UART1_Write_Text in some place of code. Problem is Random reset occur in both project or some time my program halt or do wrong code. At first I wonder that my Micro has some damage or Flash r...

Hello
Take a break of 30ms between the write commands.

It works . Thanks.

Hi, i am trying to read and write on EEPROM with EEPROM_Read command on PIC16F877A. But it reads wrong address or something is wrong code is this: Sub procedure Update_Events() Dim read_buf as word HI(read_buf) = EEPROM_Read(0x0) LO(read_buf) = EEPROM_Read(0x1) EEPROM_Write(0x0,hi(read_buf)) EEPROM_...

Hi I am trying to set all PORTB Pull-up resistors on in a PIC18F45K80 but RB0 , RB1 and RB4 denied to active pull-up resistor. My register settings is: PMD2=%00001111 TRISA=0 TRISB=255 '%00000000 TRISC=0 TRISD=0 TRISE=%00000000 INTCON=%11010000 INTCON2=%00000000 RCON.IPEN=0 ANCON1= 0 WPUB=255

same problem here! what is the problem!?

read mikroprog manual page 20: advanced option.

Thanks! It works

Hi,

I wonder how to not write in EEPROM while I am writing new version of "code" into chip!? everytime I try to update my code EEPROM has erased by "mikroBasic PRO for PIC" program.

Any advice?

Amazing replies and trick I have learnt from this topic . :wink: I have found the problem, It was in a do ... loop see: try=0 m=0 again: do data = Soft_UART_Read(m) inc(try) loop until (m = 0) or (try>10) IF try = 10 then delay_ms(10) goto again end if My crystal speed is 35mhz and UART baud rate is...
