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

I started writing notes: RFM70 notes Only change mode between RX and TX while CE is low. In TX mode, set CE high AFTER the payload has been loaded in...

I don't know what is going on here but this is what I have figured out: - The RFM70 will not change from PRX to PTX if CE = 1...

Oh my god. I still have the same problem, no IRQ on the IRQ pin (and the TX_DS bit is 0) when transmitting a packet unless I go to power...

I tested some of the registers, and it seems like you cannot read the STATUS register when CE = 0. The register content will not be shifted out when writing...

Yeah, but they have just had a week of holiday, so I guess their mailbox is full of technical questions from customers so I don't expect a quick reply ;-)

godfatherAnd what I suggest you can use CE in always enable mode if you are communicating with only one SPI device say RFM70.I am only communicating with one device. So...

I can tell you for sure, many registers are active in standby-1 mode (CE = 0) because I do ALL my initialization with CE held low. My understanding of the...

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

Another thing I noticed. When a packet is received and the IRQ pin goes low, I read the RX_DR bit in the STATUS register, just to make sure the interrupt...
