Thanks a lot.
I tried to compile with one soft and on hard I2C but without any success.

For the power supply, i will use a LM2678

Hello,

Do you think it's possible to address more than 8 MCP23S17 if I play with the CS pin.
I need 12 MCP23017 or MCP23S17.

Thank you for your help !

Hello !

Is it possible to have one I2C hard AND one I2C soft on the same chip ? I tried but without any success.
I'm working on a port expander but I need more than 8 MCP23017 ( 12 exactly ).
(I will use 18F6527 or 8527).

Thank you for your help !

Hello, I try your code with my own GLCD. The CS1, CS2 and Co are connected to the PORTF so I modded your code but my GLCD had a RESET PIN connected to F5 and even if I set this PIN in Flowcode, the F5 PI stay clear and the GLCD doesn't start. If i put a pull up resistor on F5, it works but I need to...

Hello !

I have one ECIO40P and it works very well.
I would like to know if it's possible to have the same bootloader ( 18F4455 ) because it would be great for my application to program directly by the usb port.

Thank you so much !

Hello !

You can use the 18F4431 who have more than 2 PWM and use c code or you can make a macro interupt who simulate pwm in software.

Hi everybody, For exemple, I have a 18F6622 with two hard UART. I have two other cards who send 10 bytes at 19200 bauds and I would like to receive it. The problem is that the two emitters can send data at the same time and I have to receive all bytes without lost. Is it possible with Flowcode ? I h...

Tomorrow ??

I try to use your program. It isn't finished yet but I just want to thank you for your job and your very complete post and comment

Hello ! I have a pb when I want to compile a program who implement RS232 on the 18F6390. Flowcode tells me that : C:\Documents and Settings\Mathieu\Bureau\test 18f6390\Flowcode1.c(515:10): error: unknown identifier 'rcreg' C:\Documents and Settings\Mathieu\Bureau\test 18f6390\Flowcode1.c(515:10): er...

Yeah ! Very good news.

Is it possible to have the new functions between V3 and V4 ?

Thank you an good luck for your new version

Thank You Benj,

I tested and I think it's works well. I have a little problem but I think it's a problem of interupt priority.

Have a nice day !

Flowcode 4 will do this I think but in Flowcode V3, the only way is to add C code. You can also look the RS232 component code an create a custom component with the code moded to use the second UART.

In fact, I had already changed RCIF by RC1IF and RCIE by RC1IE without improvement. The error message is always here. I try to put your C code without any change. By coincidence, I added an interrupt by TIMER0 overflow ( but the associated macro is empty ) and my LED lights up but communication work...

In the attached file, you have my test program who doesn't work with interupt macro but works without...

I'm sorry but I need your help.... I try different things but I doesn't work. I test a little program who generate 2 PWM when receiving 6 bytes. Without interupt, it works well. With interup....nothing happen... I light up a led if the program enter in the interupt macro when receiving incoming byte...

I try your interupt code but it doesn't work. I don't understand very well interupt yet so I think i make something wrong.

Is it possible to have an example receiving more than one octet ? ( In my program, I have to receive 14 octets )

Thank you so muh !

Thank you Benj !

My clock speed is 40 Mhz but I think i put the good setting for spbrg because I look into a .C generated by flowcode when using 19200 or 38400 baudrate. Do you think its possible to set different baudrate on the same UART ?

Im using 18F6627.

An other thing : I have to switch between two RS232 baudrate. 38400 for Rx data and 19200 for Tx. I just put a C icon with spbrg and I put 64 for 38400 and 129 for 19200. Rx works well but 19200 doesn't.

Any ideas ?

Thank you very much for your (full) answer ! In fact, I receive data from anyone but time to time I lose bytes. I can better estimate the nTimeout value now. Interruption is very interesting! I got the latest Flowcode release but I don't have that option in the interruption icon. It must be a user i...

Hello,

I have an other question about nTimeout. For exemple, if i set 20, how many time the PIC wait fo an incoming data ?

Thank you!

Hello !

An other question for you....

Will the Flowcode v4 exist also for the AVR and ARM versions?

Thank you Benj,

As I had no bug with the LCD with the old version, I just copy the old files. I will try your tip later.

Thank you again !

Hello ! I had a program that worked well with the old version of Flowcode (3.4.7) but with the latest version, my characters are shifted on my LCD screen (the simulation works well but it doesn't in the real life). Recompiling the program with my older version and my program works again. What's the ...

Hello ! I have an other question.... I use a joystick which gives me a variable between 0 and 255 and setup my PWM duty cycle. What I want is add a trimmer which setup my PWM frequency without make any change on my PWM duty cycle. I don't understand how PWM works, all my tests change my PWM frequenc...
