So in the meanwhile I hooked up another RF device and re-soldered and re-checked everything again.
Nothing seemed to work either; next week I'll hook it up at a scope at office.
I am trying to communicate to a Zigbee antenna, model as in subject.
Today I tried various settings with no avail; I have prepared my Omega2 BASE to get gcc tomorrow so I might try more accurate tests.
Various threads involving SPI issues I've seen:
For the time being, I am attempting a short read as at page 14. This seems coherent with what
spi-tool ... read <-->
spiTransfer would be able to do.
spi-tool -b 1 -d 32766 read 0x00
Expected: 0x00. Got: 0x00. So far so good?
Unfortunately, I always get only 0, for everything I read, for example:
spi-tool -b 1 -d 32766 read 0x2C
Expected: read of register 0x16 (PACON0) value at POR 00101001 = 0x29
I figured maybe my pins were wrong or perhaps frequency too high. So I tried
spi-tool -b 1 -d 32766 --frequency 50000 --bpw 8 --sck 7 --mosi 8 --miso 9 --cs 6 setup
Attempted other reads; this device has few non-zero fields but with no luck. I always get 0.
I need help troubleshooting this, because I have checked the connections 42 times and I'm now out of ideas. I only have a $10 multimeter. BTW, will spi-tool or the library (they are sorta equivalent from what I see) support 12-bit values? If the command-response model has to be honored, I need 12-bit values to perform long reads on this device.
