hi
I'm trying to get an RS232 click board working with a clicker2 board using microbasic.
My code is as as below. I don't get anything out of the serial port. It's just a very simple program to start with to get the 232 click working before I move onto more complex code. Within the code I also have a bit of code to turn on an led when a button is pressed and that all works OK. It's probably something very simple that I've not done but I can't spot it. Have looked at rs232 click examples and can't see what I am missing
Thanks
Paul

HI every body
I would like to generate two PWM signals from different channels and with phase shift between them (time delay),
I use PIC32MX795f512l , developing kit EASY PIC 7 FUSION , MikroC Compiler .
thanks to LIBSTOCK Team

Hi everyone - great site!
I have an Intel Edison board which runs Linux (somewhat similar to a raspberry pi) I was able to install all the packages and libraries and it seems to run the command line aplay XYZfile.mp3 just fine (but of course, I can't hear anything as of yet).
So from what I understand, I still need to connect my Edison to an mp3 sound card such as MP3 Click that can receive that XYZfile.mp3 and play it/send it to speakers? I am correct in these assumptions?
If yes, could you please guide me on how to hookup the MP3 Click board to my Edison breakout board? FYI, my breakout board has been level shifted to 3.3v on all pins.
For more info on the Intel Edison breakout board, here is the link for the schematics and pin diagram information:

I really REALLY thank you anyone that can guide me to the right direction.
Regards
Flavio

Key Words : ADC, PWM, Servo, LCD
I want to know the code of this Basic Algorithm.
Is it possible fixing Servo at specified angles according to Analog input value ?
I wonder it requires Internal Interrupts or anything else to do it all.
It was easy to browse PIC codes of controlling Servo, but hard to get some other codes of controlling it even here.
I hope someone else who are better than me to give some tips.
Thanks alot (in advance).
