ad9850 bascom
we are having hard time in writting the program in PIC together with the AD9850 which is a programable waveform generator IC.
The components of the Project are:
(3x4)KEYPAD - TO input the DESIRE frequency in HERTZ.
(HD44780)LCD - Display the FREQUENCY INPUTED in the KEYPAD.
AD9850 - the programable waveform generator IC from analog devices.
requirements:
max freq = 5MHz
frequency resolution of = 1Hz
The AD9850 is connected in parrallel with the PORT D of the PIC16F877A with a 20Mhz Clock. The reference clock of the AD9850 is 50MHz. The IC is 40bit programable.
If we input a certain frequency in the keypad it will generate a 40bit code for it to be loaded in the AD9850 also at the same time it will display the inputed frequency in the LCD display.
Help us in writting the program.
