Posted: Fri Mar 13, 2020 8:13 am Post subject: DDS AD9850 Controller for Arduino LCD Keypad Shield.
Analog Devices AD9850 is controlled by Arduino LCD Keypad Shield.
The frequency can be set in units of 0.1 Hz.
(There is an error because the resolution of DDS is about 0.0291Hz)
99 memories that can store frequency values.
If there is an error in the crystal oscillator of the reference clock [REFCLOCK], the output error will increase, so it can be calibrated in the program.
Operate using the character LCD and key switch mounted on the “LCD Keypad Shield” board.
Move the setting cursor displayed at the bottom of the LCD to set the output item and frequency.
The operation method of the key switch is described in the following "Operation Manual".

That is a great collection of DDS controllers projects you are sharing.
And as usual great quality with all details.
I appreciate the fact that you took time to translate into English and publish it.
