Hi, I have the following issue.
I bought a High Precision AD/DA and followed the steps in this forum: High-Precision AD/DA Board - Waveshare Wiki. But when I run my script it tells me an “ID READ FAILED” error, I checked all the forums and there is not much information on how to fix it.
I read that I had to activate SPI, and I did, but I still have the same problem. What can be the solution.
These are the configuration pins for my Jetson Nano Developer Kit.
# Pin definition RST_PIN = 18 CS_PIN = 22 DRDY_PIN = 17 clib = ctypes.cdll.LoadLibrary spi = clib('./sysfs_software_spi.so') # SPI device, bus = 0, device = 0
I followed the steps on this forum GitHub - JetsonHacksNano/SPI-Playground to activate my SPI, but it still doesn’t work.
