Hello, I want to interface a digital FM radio with my mini2440 device. Frequency and volume will be set using either serial port or GPIOs. Anybody knows suitable hardware for FM receiver?
Interface digital FM radio with mini2440
Unless the radio has a control interface built in you have a BIG job ahead of you. If the radio has a SPI controlled Synthesiser and an E-pot for the volume then this only becomes a medium-sized job.
I've used the USB FM RADIO from Silabs before. It is USB though but easy to interface. http://www.silabs.com/products/mcu/Pages/USBFMRadioRD.aspx I used the DLL from the following page: http://code.google.com/p/silabsradiodll/
Hi is there somewhere a purchaseable fm radio that works under Linux on the mini (and could be controled from the comandline)? The website of silabs.com says: "Note: This reference design is no longer supported, and is not available for purchase." I tried the Dlink DRU R100, but the fmtools don't work: [root@FriendlyARM media]# lsusb Bus 001 Device 006: ID 04b4:1002 Cypress Semiconductor Corp. CY7C63001 R100 FM Radio [root@FriendlyARM media]# fm on fm: VIDIOC_QUERYCTRL: Invalid argument
Thanks for the interest folks... I need it under linux as well. This is what I found http://www.sparkfun.com/tutorials/293 But I am confused if this can be used with 2440
I2C interface. Should be fairly easy if you know some C programming. The mini2440 supports I2C on the GPIO 34 pin connector. Tick the right boxes in menuconfig and away you go. Good luck.
