hello, you can find here all you need to use I2C1 , specific for 18F27K42 ... without mikroC library ... used for OLED display and DS3231 RTC needs to add specific register names, not included in MikroC registres I2C du MCU 18F27K42 sbit I2C1STAT0_BFRE at I2C1STAT0.B7; sbit I2C1STAT1_TXBE at I2C1STA...

hello, .....Your code is working fine. but if print number in next line it will not work. char c: int value; int i=0; .. somme init here.... do { i=0; if ( (UART1_Data_Ready())&& (i==0)) { c=UART1_Read() ; UART1_Write (c); // echo '6' en ascii value=( c-48)*10; // value=6*10=60 i++; } if ((UART1_Dat...

hello, You need to convert the values into a string. sprintf is allready used for that .. you try to put 2 bytes into a variable using an integer pointer ....so at same adress test this: define variables as (global) integer value no need to pass parameter to function void dht22_read int dht22_humi; ...

try this char c: int value; int i=0; .. somme init here.... do { i=0; if ( (UART1_Data_Ready())&& (i==0)) { c=UART1_Read() ; UART1_Write (c); // echo '6' en ascii value=( c-48)*10; // value=6*10=60 i++; } if ((UART1_Data_Ready()) && (i==1)) { c=UART1_Read() ; UART1_Write (c); // echo '5' ascii value...

hello,


what is your definition of a digit ?

Uart1_Read ( a_byte);

a value on 2 digits : ex: 65
MSB=6 LSB=5
BCD coded as
0110 00101

On other side : how are send theses 2 digits ?
in binary format 0100 0001
ascii format "65"
BCD format 0110 00101

hello, more simple solution The mikroC PRO for PIC compiler provides a set of useful built-in utility functions. The Lo, Hi, Higher, Highest routines are implemented as macros. If you want to use these functions you must include built_in.h header file (located in the include folder of the compiler) ...

hello, Impossible to give an answer without Schematic ... Does the PIC control Power delivered for the Heater ? Algorithm used PI , or PID ? The CTN formula is very long, use POW , log ... difference beetween TARGET and MEASURE needs an Integrale action .... (PI proportionnal and Integrale controler...

hello, Post your schematic ... it could help to understand what do you want to do ... if i get a good understanding, RESISTANCE is calculated via a Voltage ratio ? Did you get test the result of the function float temperature_from_resistance(float resistance) ie : trace the curve R=f (Temperature) i...

Hello Pumper, * what is the purpose of Inactive_Time variable ? * PulseTime = 35000000*4; // 140 000 000 how this value is fixed ? seems not related to FOSC MCU * what is the FOSC value ? * where, when , T1CON.TMR1ON is reset ? * at wich speed is running the main loop of programme ? 1seconde ? more ...

Hello Pumper, I don't know, how you treat the RB0 interrupt ..... A better way is to use software solution, a litle delay ,10 to 60mS inside the RB0 Int0 interrupt to debounce the reed contact... then read the satus of RB0 Pin input to confirm, yes , it is a true Low level 0 i get it ...to start the...

Hello,

For this low frequency, maybe you can use an analog input and comparator instead of Int0 RB0 interrupt
wich works with Edge detection
With a filter you dont'get sharp edge ..

hello, I would be really interested to know if anyone gets the 27Q10 processor working with 7.60 as I've just ordered some of these for a project and realised they aren't supported. The las rescent ( or not too old) PIC i can use with MikroC 7.60 is PIC18F27K42 No way for using the 18FxxQ10 ! with M...

hello,

where do you store data in eeprom ; wich adresse ..?
we can suppose start adresse is 11 ?
remark: a pair adresse is always better ...;
but not checked !!!
