UPDATE: just to let people know that I figured out the problem, I needed to update the firmware on my programmer; it now works. Thanks for reading.

I am using the MikroC pro compiler with a usb programmer. I have a simple program (LED blink) that works and programs perfectly on a PIC18F26K22. When I edit the project to use a PIC18F27K42 I get a popup window that says "Device Not Recognized; MCU selected PIC18F27K42" . I have several new K42's a...

paulfjujo,

thank you for the help; I did not have success with the Tools Layout toolbar but simply started a new project with the old code and things eventually worked for me.

Somehow I managed to set the watch window so it is displayed horizontally across the page with the program code below it. I've tried the forum and messed around with MIKROc ad nauseum. I cannot set it back to the way it used to be (sitting to the right of the code display). I suspect it is something...

hexreader, thank you very much; it now looks so simple that I'm a bit embarrassed that I didn't think of it.

Hi, I just want to add a minus sign(-) to a float and send it out the serial port (PIC 16F876A). Why is it so difficult? Can anyone give me some (simple) advice on how to proceed? Without the 'printf' function I'm having a difficult time. I'm using the MikroProC compiler.

Thank you, Marc

though I've used PIC's awhile, I've never tried to have one microcontroller talk to another (PIC16F876A) using SPI protocol. (MIKROC compiler) I can see the Master output change on a scope as I raise and lower the pin ("INPUT") but I cannot get the Slave pin (RB0) to change. I know I'm overlooking s...

I am trying to do some floating point calculations and am having some problems. I suspect that the two functions in the c_Math library in Mikro C , ldexp and frexp may be helpful to me but have no idea how to use them or what they are for. I can find little to no explanation in the 'help' menu as to...

To all: Thank you for your help. I have solved my atoi issue with all your help. Basically what I am trying to accomplish is to control 2 servos with a joystick and an RS232 link. I've foun that the most efficient way is to send one long string over the link (format: 123456aok0). The 123 is position...

Could someone tell me what I'm doing wrong with this simple code??? I can't seem to get atoi to perform the way I expect. Thank you, Marc /* I'm running this program on a PIC18F450 at 20MHz using the MikroC compiler */ unsigned short result; char teststring[3]={0,0,0}; char uart_rd; void main() { UA...

Aleksandar,
thank you very much for your help. I appreciate it.

I am using MIKROC and can find no "split string" function. I have a string 6 characters long and need to split out the last 3. The first 3 are letters and I managed to seperate them using "memmove" from the C_string library; how do I get the next 3 that are digits? Any suggestions would be appreciat...

Hi Tom,
I have a silly question: if the slave is using portC for inputs to send data back to the master, how do you connect the master to the slave since the I2C link is already using two of the portC pins (14 and 15 on the PIC16F876A) thank you, Marc

thank you for your input; I have it working now. Marc
