I have been searching google for a transistor circuit that could invert my pwm signals from uC couldnt find one. Benj can u suggest me a resource for this circuit?

Sorry i was away for few days.
Benj after changing aquisition time from 40 to 200 program works fine now.

this is what i get when read as int or byte.

The adc works fine if i read as voltage at FRC. 20MHz HS setting.
But read as int, byte creates problems. I dont get whats going wrong?

and how can i do that? Can u explain please

i do understand, you guyz are doing an amzing job whatsoever. I wish u and all MMX team a very shining future. Please update me on adc asap.

usinf 16f877a, please read this topic ive posted screen captures here.

Here are some of the issues that u might wanna fix. ADC if read as int the output to port D doesnt work for me. ADC if used with 20 MHZ crystal setting it doesnt work for me. Same code with same crystal setting work just fine when complied with fcv4.5 regarding USART ill locate the post i read on MM...

FC5 is full of bugs, output to port D doesnt work, Using dsp comp. adc aint compiling. i read there is an error in UART. Why it is so scrambled. FC4 is still stable but less options.

program compiled with fc4 runs ok but adc prog compiled by fc5 gives this error

{"ADC Conversion started before wait time has expired following previous conersion or channel change"} i dont know why?

program speed set on both fcv4 & 5= 20MHZ

martin can u suggest me a chip having equal as much IO's as 16f877a have?
another problem in Flowcode 5 ADC Conversion i am posting sc's for details.

Plenty of signals are lost too while outputting other instructions. How much time these flowcode macros take? Macros such as ADC, PWM, LCD Display, etc.

Martin i wanna use pwm for driving an H-Bridge. H-Bridge is used to power a stepup transformer. Is it ok to have this much delay?

transistor option is better? will it cause some delays too? pls recommend a good circuit benj. Problem with pic 12 is less io's martin.

Hi,
Is there any way i can create a normal & inverted pwm using 16f877a?

How can i invert the pwm for pushpull loads.

i am trying to understand how to init 3 level pwm to obtain 50Hz sine output. I have to use pic16f877a. i also need to put some lcd functions voltage readings from mains and battery etc.

Keep up the good work brainiacs.

Aah! Silly me. i was used to fc4
Sorry guyz, got it now.

here is a screenshot. i cant c 2nd pwm in component macro and over panel.

Hello,
I can only see one pwm for 16f877a. I know there are two pwms for this chip. This has to be a bug or restriction in trial version?

im trying to output 8bit data to produce sine wave, but i keep getting triangle wave at the output. m using r2r ladder to convert digital to analogue.
Can someone help.

Thats alot of info.
Thanks Martin.
