Prova_basica_2

Hello there,

I've almost arrived at my goal!

I've almost arrived at my goal! But; I don't know how I should continue. I will send you two files. They're created with Uiflow 2.0. The first version, named Prova_basica_1 is absolutely functional, and the second one, named Prova_basica_2, is my nightmare!

The trouble finds in the conversion from ASCII code to character, I can't do it

Please, may you aid me?

Thank you, and excuse me for the inconveniences.

Best regards!

P.S. In this message I send you two images from UiFlow 2.0 program and I've just attached below the code from two programs

Code Prova_basica_1:

Hello,

There is a few days ago, I wrote a similar trouble. My message was…

Hello,

I didn't think that I could feel so interested about this system! Sorry for my questions about, because I'm very unexpert.

I'm math teacher in secondary in Spain, and I want to prepare a trigonometric practice very simple.

I've used a potenciometer (angle unit), PaHUB, PbHUB, 8servos unit, and two servos: one 360º limited, and another one, 360º unlimited. Until this moment, all was right. But, I've done some little changes, I wasn't conscient that, when I erased the PaHUB unit, and I added another one, some address changed. I reviewed all the program, and I think that it should run. But, I don't know why now, when my program is running, at the end of compilation, it appears this message "E (112496) i2c: i2c driver install error".

Thank you for your attention

Please, does someone aid me?

Thank you for my poor English. Best regards!
