HI,
I trying to develop a module for USB and I need to use PLL to make internal oscillator to 48 MHZ.
for this i need to access CW4<13:10> , I dont find CW4 register and hence gives an error !
so what can I do , help required !
I have gone through it, but its about connections with Micro/mini USB devices, I need connections for a standard USB flash device, thats why I mentioned I have only 4 pins on my USB - D+,D-,Vcc,Gnd. I got confused where to connect Vbus in this case and how do I get device address when no...

Hi,
I am trying to interface a USB to my PIC, can any body provide the interface connections.
In my project I am monitoring adc channel and do the required calculation on it and can see those working fine by printing on Hyeprterminal. Now need to save those...
Timer Delay Calculations:
* 1. Timer Frequency Ftimer = Fcy. ( Fosc and Fcy are different check data sheet)
* 2. Using a Prescalar then
* Ftimer = Fcy / scalar value
* 3. Time Interval Ttimer = 1/Ftimer
* 4. To calculate the value to be filled in...
then you have to write a loop function with required delays ,and a pointer pointing where of array to start display on LCD. though it looks like scrolling you will actually printing the text you want to display.
array[40] = "this is my first movable display program";
for(i=0;i<40;i++)
{
//...
Easyrider was referring to function rx_data() that you called in ISR
void RC_ISR(void)
{
PIR=0;
rx_data();
}
if dont receive data the program get stucks up in ISR.
instead raise some flags and call it in the main function.
I am trying to refer to in AN392 data sheet. He had shorted four pin of microcontroller and connected to gate and traic firing is done as per the figure 3 in data sheet.
:
how to switch triac(BT139) without using Zero detection opto-isolators ?
I want to drive triac directly with microcontroller. I have connected as shown in figure.
its because you are sending it to display only one letter and you not mentioning where to display that letter. so it is always showing in its start place.
better inbuilt functions for display.
Nice and thanks FvM
I am not much worried about the time taken. I am using in an user interface application, where user have an option to erase all previous stored data. Though user does this rarely, I am concerned about the number of write cycles I am using for it, to make all the addresses to...
I have no problem in writing or reading Serial EEPROM !
In my EEPROM I am using addresses from 0x0000 to 0x1A20(available 0x0000 to 0x7FFF). For this I use multiple times, writing 0 to EEPROM. Instead of using the write multiple times, is there any possibility to reset every thing to zero at...
HI
24LC256 Serial EEPROM,
I am using EEPROM with I2C , and I use a lot of commands to make all addresses to zero state. Is there any method , so that I can completely erase all data in my EEPROM at once ?

Raady.

Hi,
I am interfacing s25FL032P flash memory with my pic through SPI. how to calculate and set SCK required to use.
For normal read mode in S25FL032P speed is 40Mhz clock speed. For setting prescalar bits in SPIxCON1 of PIC24 how do I calculate the what prescalar...
