Hello,

I get the tx_msg[3] = 4; to send "a" and
tx_msg[3] = 5; to send "b" etc.,

but I was not able to find a map for all the rest of the keyboard keys. What is the value ...

Is this a #PRIORITY problem?

Are you trying to read too many I2C bytes?

Have you tried the hardware PWM and SOFTWARE I2C?

Hello all,

I just wanted to post for those who may have come across this problem:

If you are trying to use the ex_usb_kbmouse2 project with the PICDEM FS USB demo board and keep getting DEVICE N ...

Hi.

I've tried to install CCS (Compiler Version : 4.057 ) on UBUNTU 9.04
and I couldn't make it work :(

I've tried with 'Wine' emulation.

Has anybody tried to install CCS on Lynux ?
Is ther ...

You apparently didn't consider the fact, that an USB keyboard usually is following the HID (human interface device) class specification and not sending ASCII codes. If you intend to build a device, th ...

Hey all,

All I want to do is have the PIC18F4450 act as a USB keyboard. I looked at the examples, but they are less than intuitive for me.

What would an example program look like that sent the ...

Hello,

I have a quick question regarding PIC bootloaders:

Let's say I have a test fixture that has a PIC with MSSP, its own test program, and the latest version of the code for the PIC in a sepa ...

Hello All,

I have a really quick question:

I'm using a PIC16F677 which has some internal EEPROM that I would like to use to store calibration values set by a test fixture.

What is the #FUSE s ...

The obvious 'danger', is in 'toggling' LED's. Don't. Toggle an internal bit in a variable, and output this to the LED's. The most likely problem is that the resistors in series with the LEDs, are not ...

Hello All,

A friend built a program around a PIC 16F887 / PICKIT2 demo board that worked properly.

He used Timer0 to flash an LED at 2kHz, and Timer1 to flash an LED at a slower 800Hz. Timer0 w ...

hello all,

I am having some trouble with the i2c_poll() funciton.

I don't want to use the SSP_ISR because it ties up my slave processor too long.

So I wrote a really quick slave routine that ...

Are you sure you mean mSec, not uSec?....

Don't call an ISR at all. Assuming you do mean 'uSec', probably 50% of the time involved, is actually getting into, and out of the ISR, not what you are do ...

SO TO SUM UP:

I HAVE to respond to an input within 2msec. My SSP on my slave device takes about 25mSec in its SSP_ISR to respond.

What ideas do you have to get around this so that even if the s ...

Hello All,

I was able to solve this problem I making a delay_ms(1000); before the first i2c_start() command gets executed. I still have to experiment to see what is the shortest delay to get consi ...
