    RFM70 - how to write code for the RFM70

    Hi forum, The RFM70 (and the newer RFM73) from HopeRF is a cheap and powerful 2.4GHz transceiver that I use in some...

    cc859ecf-6171-426f-8b65-cc272292c487

    I started writing notes: RFM70 notes Only change mode between RX and TX while CE is low. In TX mode, set CE...

    I don't know what is going on here but this is what I have figured out: - The RFM70 will not change...

    Oh my god. I still have the same problem, no IRQ on the IRQ pin (and the TX_DS bit is 0) when...

    I tested some of the registers, and it seems like you cannot read the STATUS register when CE = 0. The register...

    Yeah, but they have just had a week of holiday, so I guess their mailbox is full of technical questions from customers...

    godfatherAnd what I suggest you can use CE in always enable mode if you are communicating with only one SPI device say...

    I can tell you for sure, many registers are active in standby-1 mode (CE = 0) because I do ALL my initialization...

    Well, maybe I got some things mixed up. In power down mode, all SPI registers are available. But the datasheet does not...

    Another thing I noticed. When a packet is received and the IRQ pin goes low, I read the RX_DR bit in the...

    Ohh, I can read the dynamic payload AND make the TX work if I have a small delay (like 1us) between setting...

    Ok, I made some time for testing tonight. I have disabled all Bank1 writes so I only do a minimum of initialization...

    Thanks, when I get the time, I will test for the problem again, but this time without changing any parameters in Bank1...

    Do you initialize Bank1? HopeRF says the default values are fine and that the memory in Bank1 is non-volatile. But you need...
