Re: Menu system with PIC

...if nobody has a sample menu in flowcode but maybe a good lead idea for a menu structure...anything?
I am wondering how you do it: do you scan the keys continuously and once you get a hit you execute and return?

Keypad.c with inverse logic and I/O

Hi, I have recently bought my Flowcode PRO and I have a board that I built to use for a AV switch using an arrow-keypad, enter and escape. I was in the process of trying to learn C before I ran into flowcode. Now, my keypad connections are similar to the keypad e-block, only that the rows are connec...

Menu system with PIC

Hi everyone,

Does anyone have a flowcode example featuring a user selection menu system on LCD?
I am new to Flowcode and embedded programming and I am working on a AV switch for my audio system.

Thank you,
Leo.

This Flowcode is pretty exciting, I am glad to be aboard. :P

I2C controlled port expansion

I am trying to connect a couple of PCA9534 IO port expanders via I2C to a PIC18F4321 and I am using the Flowcode Pro v3.6.11 to which I am fairly new but I am even newer to I2C. The comm speed is not important and there's no need to get back any interrupts as all the expanded ports will most likely ...

Re: "Call stack usage exceeds: #" in Flowcode 3 PRO

Thank you Kersing.
That was it; I had too many nested subroutine calls.
It works fine now.

"Call stack usage exceeds: #" in Flowcode 3 PRO

I am new to Flowcode and fairly new to programming embedded. After putting together a pretty good size (I think, because I have a good number of macros) code for PIC 16F877A, at some point I started getting this error when compiling to hex and about at the same time the code started behaving in the ...
