Hello all,
i am working with zstack and cc2538Soc from last 2-3 months but i didnt understand few thing ->
1) how zigbee (IEEE802.15.4) radio is interfaced or connected in CC2538 cortex M3 SoC ? anyone has any idea ? they connectd via UART or I2C or SPI or via system bus (then which system bus) ?
2) when TX SoC transmitting data then how it is received by radio and where it is storing that data ? i mean to say at receiver side data is picked up by antenna and how it processed this data from ant -> phy layer-> in which register ? in zstack HA 1.20......
3) where that register mapping or initialization is given.... from the Datasheet of CC2538 i know there is one TX FIFO and one RX FIFO but where that FIFO is given in zstack HA1.20 or its reference or implementation in zstack?
4) now once data is stored in PHY layer how it is forwarded to MAC layer ? means in which FIFO or buffer or how ? and where its reference is given in zstack....
if anyone has any idea about above question then plz reply back.....
Thanks & Regards,
Maneesh singh
