to pass IQ baseband samples to SX1255 over I2S, run this: | |
./zmq-sub | aplay -t raw -f S32_LE -r 192000 -c 2 --device="hw:0,0" | |
note: you need to enable I2S overlay (acting as a slave) | |
this one works good: https://github.com/AkiyukiOkayasu/RaspberryPi_I2S_Slave | |
note: setting the rate to 192k isn't really effective, the actual rate is 125k (governed by the I2S master - SX1255) | |
