It seems that I'm facing another problem with the UART and the 16F688. I've a problem with the following line: if (UART1_Data_Ready() = 1) then it seems that I always got a "1", I've tried the example: program UART dim uart_rd as bytemain: UART1_Init(9600) ' Initialize UART module at 9600 bps Delay_...

OK merci pour ces précisions - thank you - gracias - danke - grazie ...

Well, the problem came from the internal clock setting. This has solved my problem: OSCCON=OSCCON or 0xF0 'set Internal Oscillator Frequency to 8MHz The question is: In Project > Edit Project I had correctly set the frequency to 8 MHz. Is this not written to the PIC? Thanks for this information

The start string "Ready" is displayed in the terminal like this:

I've been facing some troubles with the UART communication on a PIC16F688 (14 pin). Finally I closed my project and tested the simpliest possible code: the UART example. Even there I had strange behavior, when I send 1 I got ~, 3 I got æ etc... I'm using EP4 (and have conected Rx to RC5 and Tx to RC...

Hello All, I had the following working well on previous MB versions: const charc as char[5] =(0x38,0x44,0x44,0x44,0x20) 'c sub procedure display (dim byref the_char as char[5], dim temp as byte) [....] end sub Now the compiler says "Incompatible types ("constant" to "variable by reference") ". Does ...

By the way I already test it before and as I wrote earlier, it seems that the freq of the interrupt is not correct...

Can't figure why!

Hello Man,

Sorry but I'm not sure to understand want you mean.
You want me to test with no prescaler, starting TMRà and then initialize R, G and B?

What's the reason for that?
Thanks

Sorry I didn't write it: it's a PIC 16F616 and TMR0 is 8 bits.

Thank you barry for your help. I only have TMR0 intterrupt thus I can reload timer on every interrupt. It really seems to be a clock problem cause with that code I have the first (RED) LED blinking every 3s! program Simple_RGB ' Declarations section '------------- Symbols ------------- symbol R_out ...

I've OPTION_REG=$06 'Prescaler = 128 TMR0=50 and tested only the following into the interrupt procedure: R_out=R_out xor 1 'toggle first LED which should lead to 1/(256-50)*0,5us*128)~76Hz frequency but... I see the LED blinking (fast but I see it!) :( The clock is set as internal and configured to ...

I would prefer knowing what's wrong and learning out of it... It suppose that something is wrong with the interruption, it's like the TMR0 overflow only every half sec or something like that... I tested setRGB(1,0,0,50) and then I see the LED flashing. The freq is so slow that I see this little 1/255!

i=i+1 forever??? never will be cleared? try this way (I don't understand well what lights have to do exactly!) while(true) setRGB(0,255,250,0) delay_ms(5000) setRGB(255,100,0,0) delay_ms(5000) i=0 wend end. On every interrupt i = i+1 that's how I get the PWM out of the interruption. Reseting i here...

255+1=0, no?

I mean it will roll over.

I've already tested with reseting i with I've the same problem...

Thanks for your input!

It's like something goes wrong during the interruption (seting the RED and only red and then stops) and the RED "freeze" for sometime. Here is a video of what happens with only the following code (in the main): setRGB(255,70,0,0) http://www.youtube.com/watch?v=mtpU5wLJ2Yk (the bright LED is covered ...
