Hello guys. I'm trying to test Using RFM69 with Arduino uno and mega, but having issues. I'm now describing the situation.
I read the wiring schematics from topics
http://lowpowerlab.com/forum/index.php/topic,239.0.html and
http://lowpowerlab.com/forum/index.php/topic,171.0.htmlBut i'm not sure that i understood exactly. So my connection for uno is as following
pin 10 -> NSS, pin 11 -> MOSI, pin 12 -> MISO, pin 13 -> SCK, pin 3 -> DIO 0, 3.3V and GND correspondingly.
In connection NSS, MOSI and SCK are connected through 2.2K/1K
And mega is as following
pin 53 -> NSS, pin 51 -> MOSI, pin 50 -> MISO, pin 52 -> SCK, pin 3 -> DIO 0, 3.3V and GND correspondingly.
Here also NSS, MOSI and SCK are connected through 2.2K/1K.
Can somebody check this wiring and correct if wrong ?
?
And also i upload Struct_send and Struct_receive to arduinos. When i open Serial monitor it
Transmitting at 433 Mhz...
SPI Flash Init FAIL! (is chip present?)
Sending struct (10 bytes) ... --------------------------------------------
Listening at 433 Mhz...
SPI Flash Init FAIL! (is chip present?)What does it mean "SPI Flash Init FAIL!" ?
what the reason is for this and does it affect to work of RFM69 ?
