A question for arduino gurus (Farhan Sweeperino)


 

Good morning for all


I must confess im an analog man i feel good in an analog world and discrete components.


As my first digital project i have an Ashar Farhan sweeperino in the? bench my progress so far as? now is finished the ad8307 board .


My question is can i replace the si570 board in sweeperino for the raduino si 5351a using the same arduino sketch.


Thanks to all in advance




 

Nestor,

Just a quick glance through the data sheets for both devices leads me to believe that the tuning algorithm will not be the same for the two IC's. Each uses a different method to generate the clock frequencies. There are libraries available for the Arduino for both devices, and you'd need to examine the actual function that sets the frequency for the si570, and write a compatible function for the si5351 in the Arduino sketch.

I am looking at sweeperino_lcd.ino at:


line 4:

#include <si5351.h>

#####################################

In the setup() function, lines 195 to 204:
?
Serial.println("*Testing for Si570\n");

si570 = new Si570(SI570_I2C_ADDRESS, 56320000);
if (si570->status == SI570_ERROR) {
printLine1("Si570 not found");
Serial.println("*Si570 Not found\n");
si570 = NULL;

Serial.println("*Si5350 ON");
printLine2("Si5351 ON");


Based on the code, it looks to me[1] as if the Sweeperino can use either the Si570 OR the Si5351.

Are you, by any chance, planning on implementing the Sweeperino Modifications, as noted here:
