I need help for the I2C zilog program master and slave function using 3-axis gyroscope. anyone knows a program about this? we really need this for our project study. thanks

I have tried a lot to get any of the four possible 16 quad encoder counters (Tim2 -5) running, with no success. Can anyone have a suggestion? See my sample code below.

i want to use orther pin in soft Uart code.but not work.this code:
char i, error, byte_read; // Auxiliary variables
void main(){
UART1_Init(9600);
error = Soft_UART_Init(&GPIOA_ODR, 7, 6, 9600, 0); // Initialize Soft UART at 56000 bps
if (error > 0) {
GPIOD_ODR = error; // Signalize Init error
while(1); // Stop program
}
Delay_ms(100);
while(1)
{ // Endless loop
// Send bytes from 'z' downto 'A'
Soft_UART_Write('a');
Delay_ms(100);
byte_read = Soft_UART_Read(&error); // Read byte, then test error flag
if (error) // If error was detected
GPIOD_ODR = error; // signal it on PORTD
else
//Soft_UART_Write(byte_read); // If error was not detected, return byte read
UART1_Write(byte_read);
}
}
Uart1 is hard uart.

A library to use these Pic family internal RTC would be very useful. I use MikroBasic.
Thanks

Hi,
Looking for examples for ConnectEVE TFT screen and ATmega32, I have an easyAVR development board but havent been able to find code samples for atmega32, have only found for xmega controllers
Thanks
