Hi i have a question i have mb 5.01 and there is a example whit the ccp module to make a pwm generator , but there is no example for the ccp capure mode and ccp compare mode to see how thats works , so my question can there make some examples of them whit a input to compare and capure , thank you for your help. and how i can use the srf05 ultrasonic range finder in to basic ,
thanks for you reactions

Good morning,
I'm using a PIC32MX795F512L with MikroC for PIC32 with license.
I'm using the "UART1 Receive interrupt" and an "External interrupt (INT0)". I wrote the head of the ISR using the Interrupt Assistant.
void encoderInt() iv IVT_EXTERNAL_0 ilevel 7 ics ICS_SOFT
void Ricezione() iv IVT_UART_1 ilevel 1 ics ICS_SOFT
In the main I set:
Code: Select all
UART1_Init(57600); // Initialize UART module at 57600 bps
Delay_ms(100); // Wait for UART module to stabilize
U1IP0_bit=1; // priority=1
U1IP1_bit=0;
U1IP2_bit=0;
U1RXIF_bit=0; // flag=0
U1RXIE_bit=1; // enable Interrupt Uart
URXISEL0_bit=0; // setting interrupt
URXISEL1_bit=0;
EnableInterrupts(); // Enable all interrupts
INT0EP_bit=1; //rising
INT0IF_bit=0; //pulizia flag
INT0IE_bit=1; //enable
INT0IP0_bit=1; //priority 7
INT0IP1_bit=1;
INT0IP2_bit=1;
EnableInterrupts(); // Enable all interrupts
In the Edit Project I set
Interrupt Control :
- Multi Vector
- Vector Spacing 32
- SRS: 7
I can't obtain the desired behaviour: if the high priority interrupt occours during the ISR of the low priority interrupt, the h.p.interrupt must be immediately serviced.
Currently the high priority interrupt (INT0) is seviced only at the end of the ISR of the low priority interrupt (UART1) (if the h.p.interrupt happens during the ISR of the low priority interrupt)
I would obtain nested interrupts. What I wrong?
Thanks a lot!

L.S.
I have an EasyPic5 and i want to use the PIC 16F648a on this board to write to the LCD display.
How write the code for LCD on Easypic5 with PIC 16F648a or 16F628a

I am interested in implementing a simple music (WAV) player using a single PIC micro with PWM, which reads music files from an MMC memory and plays it,
PLEASE USE MIKRO BASIC

It would be interesting to receive an example of operation using two-way transmission easybee boards and development tools, as the examples of mikroBASIC have only one-way function.
thank you very much
Marco
