Hi, Hello Everyone this forum has been instrumental in my design work on FPGA/8051 and now PIC. But Im stuck in a strange situation where iam required to read the status of External Interrupt and on every rising pulse I have to create a pwm of 50hz using Timer 0 to fire a thyristor. Let me explain the circuit a little bit Im reading th
I am trying to send a pwm signal on PortC5 (pwm1) using the latest ccs compiler(5.026). This is the manual method of sending a pwm and it doesn't seem to be working. I have followed the pwm Setup and generation on page 221 of PIC16f1503 datasheet. I just couldn't get it to work. Anyone have anyidea what (...)
This is to slow down the pwm ramp up. It is an unusual procedure. By the way, had you used PIC Wizard tool which come with ccs toolset to get the values that you configured for pwm registers ? +++
peace be upon you. can somebody please share any example of dspic30f4011 3 pwm code in ccs PICC compiler. i need fuse setting and initialization of pwm modules. suppose frequency is 10khz and 50% duty cycle on every channel . Thanks
hi, i made a project in high schooll like that. but i used ccs c compiler and pic18f4550, but as far as i remember. the frequency doesnt affect your rpm, it just gives an option for your switching devices such as h-bridge mosfets or transistors. you can set your frequency according to your h-bridge devices. the only thing that changes the rpm
Hello, How can I get inverted pwm in 16F73. I am using ccs C compiler for programming. Actually I need both inverted and non inverted outputs. So ideal solution for me is to have one module operating in normal mode and the second one in inverted mode.
pls explain me the following functions... // Mpwm Functions: setup_motor_pwm(), set_motor_unit(), // set_motor_pwm_duty(), set_motor_pwm_event(), // get_motor_pwm_count() // Mpwm Prototypes: _bif void setup_motor_pwm(unsigned int8 (...)
Why not read the compiler manual? Please consider that when passing a 16-bit variable, the expected maximum pulse width value is 4*period. This is essentially a PIC hardware thing and not particularly related to ccs C. The ccs specific point is to scale 8-bit and 16-bit variables differently in the built-in function. Writes the 10-bit val
You could simply set the appropriate registers, instead of utilizing routines such as setup_timer_2(). Or write your own library of routines which can be easily ported from one compiler to the next. Also, unlike mikroC, if I remember correctly, ccs provides the source code for its routines. Take a look in the directories for the source code file
i try to generate pwm signal using pic18F4431 how i would get requiered frequency ccs code pls? thanks
Hello All kind experts, I am a newbie for PIC24F series. :-(:-(:-( Does anyone can give me the sample code for the application as mentioned on thread subject? I want to have the pwm period about 10 kHz approximately. I planned to use the internal RC oscillator. Machine frequency is 8MHz. below is my starting code but the rest I need your help
To control the speed, pwm is the easy and efficient method. Here you can find a circuit and an example code for DC motor control with PIC16F877A, using pwm. While the program has been written for mikroC compiler, you should have no problem in "porting" it to ccs. From there: //-----------------------
Successfully simulated the following code for normal pwm (ccp1) in Proteus. How ever I m interested to use the ECCP capability of Pic18f4520 and Tried all the configuration modes given in the ccs c manual, but could not get pulses at the out put pins(P1A,P1B,P1C,P1D). In PROTEUS i connected pic to oscilloscope directly (pulling up MC

Hello Dear All, I have a unipolar 5V stepper motor and I want to drive it with a 16f877a. I have connected 2 pieces of tc4427 mosfet drivers and 4 pieces of IRF2807 to the pic and, as I see they are working properly. I supply 50V to the motor and I am trying to use microstepping techniques. Because the motor is 5V, pwm output of the pic neve

hi, This is a simple tool which can generate C code for ccs, just type parameters it will generate the ccs code. Try it and post your comments about it.. I were developed this tool with VISUAL STUDIO note:You need 2.0 to run this tool you can download it from microsoft's site
Hi, i'm new to the programming and I was trying to set up the a/d converter. I found this pwm example code from ccs examples, and I was expecting pinC7 as an analog input and the picC6 as a modulated output. However, when I checked the output on the oscilloscope it looked like it is not dependent on what input I put in C7! It looked like it goes hi
There are example programs available for the same when you install ccs compiler. Please check the folder where you installed the PIC C compiler. Their Help manual explains about what each example program file does. Good day. Regards, blueshift

Hi! Why are u doing this adc_result>>=6; Because if the result is say 1023 ( 3FF,maximum possible) then after this operation it will become 15(0x0f). Now in ccsC whenever u r making the project and select a particular frequency for the pwm then it shows the range of duty cycle that can be used. You have to send only those ADC re
Hi , Useful tool , good job !! Can you write a version for standard register setup like this ? PR2 = 00100000 ; T2CON = 00000101 ; CCPR1L = 00010000 ; CCP1CON = 00011100 Or may be you like share source code , I can code in delphi and make modifications for write new application not for standard ccs C output . I know is to hard

Hi there, this is not a specific question concerning ccs , but I hope someone can answer it anyway. The datasheet of the 18F452 says on page 123 in tabke 14-4 that when you choose an update rate of the pwm of 2.44 khz you can get 14 bit of resolution from the pwm. But on the other hand according to the datasheet you cann only set (...)
The only thing that comes to my mind is are you sure you have used the correct bit (Bit0) in Config3H (CONFIGURATION REGISTER 3 HIGH BYTE ADDRESS 300005h) as these registers are organized as 16 bit registers? I also saw your question posted in the ccs forum, a very good idea. best regards
Hi, How to write the Fully-Wave-Rectifier-Sine-Wave modulated pulses at 50Hz program? How to use this pulses to compare the triangle-wave and produce the pwm signal? I am using PIC16F84A or PIC16F877A chip and i using ccs compiler and C program.
Hi, it's so easy for example to creat 1khz square wave using ccs c compiler. We calcualte time duration T=1/1000Hz = 1 ms Then divide it by 2 ---> 1ms/2 = 500 us while (1) { output_high(PIN_A1); delay_us(500); output_low(PIN_A1); delay_us(500); } Bye
