Hello, I wanted to do now my web server (Arduino Mega Ethernet-Shield ) to expand a RFM12B. The previous Sketch runs since weeks without interruption. I now have the RFM12B connected. The IRQ i connected to pin D2 (INT0). I use instead for the chip select Pin53 Pin D5. I have the corresponding entries in the Jeelib amended. In addition, I have locked the interrupts in the Ethernetlib. This info I have found in various forum post.
The Sketch works in principle. The RFM12B receives the data and the web server SD-card works as well. As long as I do not want to access the web server, running the sketch for hours without errors. But, when I refresh a web page in the Browser every minute, the sketch is hanging after a few minutes or even hours?
Therefore there is an SPI-problem, which however only time by time occurs?
I have tried during the use Ethernet/SD the Chip Select-Pin from RFM12 on high, but nothing helps. When I try to use Ethernet/SD the RFM12 in sleep mode and then wake up again, depends on the sketch when waking up of the RFM12 on?
Has anybody like an idea?
Does anyone have a Arduino + Ethernetshield + RFM12 running?
Many greetings and sorry for my bad english, paulinchen
