Re: Strange timing issue

Hi

All it says in the custom code for the stop function is -

%a_I2C_Master_Stop();

I got here from the "Customize Component Code" window and then clicking on MI2C_Stop and then clicking on "edit code". I guess I am going to the wrong place.

Re: Strange timing issue

Hi there

I have attached the code I was using to test with. I have also included a screen shot of the program I use to look at the logic levels. FYI the slightly wider set of data on the SDA line is the "Please select mode-" text.

Re: I2C problem

Hi there I have to give you a massive thankyou Pete! Tried out your code and it worked! I made some minor changes to my code to make it pritty much identical to your code but my updated version still would not work. I tried copying the blocks over to a new file and then it worked. I was trying to wo...

Re: I2C problem

Hi there I did have a look at this however, it is an example using the serial comminication method with the device rather than I2C. Basically I know the I2C hardware is fine because it works with an LCD display fine on the same bus. I changed the code for the LCD to work with the compass module. Dis...

Re: I2C problem

Hi there

Yes you are correct I have it running at 100Hz. Not really sure what you mean by the I2C Phillip resistor? But I do have a 10k pull up resistor on both the SDA and SCL line.

Re: I2C problem

Hi there Thanks for your replies. I dont have V4 this is the first version of flowcode I have used. I checked to see if it was possible to use the free version but I dont believe the I2C component is available in this version. Yeah its a new module and looks pritty good very similar to the one you u...

ADC in Flowcode v5

Hi there Just wondering if anyone has been able to get the ADC component to work in Flowcode v5. I am using a PIC18f4685 at 4Mhz and it keeps getting an error when compiling the C code - "D:\Program Files (x86)\Flowcode\v5\CAL\PIC\PIC_CAL_ADC.c(1588): Illegal symbol name: (". I have had a look at th...

Re: Flowkit and 3rd party hardware

Hi there

Thanks for your replies. Eventually found the problem as usual pritty stupid! After I replaced the crystal it started working again. AArggghh. But now I can program the PIC through the easy pic programmer and it looks OK.

Thanks for your help!

Re: Flowkit and 3rd party hardware

Hi there Thanks for the reply. Really good idea you suggested there. I normally just use the ICD2/3 and forgot about the on board programmer. I tried it and it appears to work. I wrote a simple program to flash an LED and it simulates fine however, nothing seems to happen when I send it down to the ...

Re: Flowkit and 3rd party hardware

Hi there No I havent emailed microchip who sent me to here - http://www.microchip.com/cisar/ I am getting some very weird results. So I have an easy pic 6 board with a PIC18F4520 and 4MHz clock. Flowcode compiles fine then I import the .asm into MPLab. I have copied the output window from when I try...

Re: First flowcode program

Hi there I was sure that I had tried changing the settings without the PPP before and it didnt work but I just tried again and it did. If it means anything when you open the window to config the chip the first line is missing and has to be added manually. Once I did it compiles do to C and then down...

Re: First flowcode program

Hi there Thanks for your replies. Changing the did not appear to work. I worked as it did before. I saw you had added some extra lines regarding the config words and I tried playing about with these but could not get it to work. I also tried swapping the PIC for a PIC18f458 with the same result.
