Seek jumps over stations

FrankBoesing opened this issue 4 years ago · 4 comments

Hi, congrats to this great library!

I use the SI7435-D60, connected to a Teensy 4.0 - will try digital Audio (I2S) later

When seeking, it often misses stations. When retrying several times, it find the "missing" station. Tried with FM so far.

What can I do, or, what can be the problem?

Forgot to mention - i don't use the crystal, but let the Teens create 31250 Hz for the clock.

Hi Frank. Try the function shown below after sitting the receiver to FM (setFM) : si4735.setSeekFmSpacing(1); // Although the guide does not mention the value 1 (10 kHz), it seems to work better than 5 (50 kHz), 10 (100 kHz) and 20 (200 kHz) Other functions you should to check: si4735.setSeekAmRssiThreshold(20); si4735.setSeekAmSrnThreshold(10); si4735.setSeekFmRssiThreshold(5); si4735.setSeekFmSrnThreshold(5); Regards. Ricardo.

(and the I2S digital audio works great, too (just in case you did not try it so far) )
