Description
Hi,
I really appreciate your useful library. However, I encountered a problem: I couldn't tune to frequencies under 87MHz because I live in Japan, where our frequency range is between 76 - 108MHz. Upon inspecting the related functions in the library, I identified some issues. I have modified the code and confirmed that it now allows tuning between 76MHz and 108MHz.
Here are the changes I made:
I added the RADIO_REG_CHAN_BAND_FM or RADIO_REG_CHAN_BAND_FMWORLD value and RADIO_REG_CHAN_SPACE_100 values to reg_channel during the function's execution to register the value.
I modified the freq_low value to adapt according to whether the user selects the FM band or the FMWORLD band.
Below is the output from the diff command. Could you please review my modifications?
