I'm just using C, and so far I have not chosen a development tool. The info I found on sparkfun mentions Geany (and it's included in the current raspian image), so I will try that first.
There are sample programs included in the wiringPi distro for I2C and SPI. Have not tried either yet, but will eventually test-out I2C with a DS3232 clock (so I have accurate time in case my internet goes down). The GPIO connector is 40 pins (some are power and GND), which leaves 28 usable GPIO pins. If you want to use SPI and/or I2C, some of those 28 gpio's are mapped to SPI or I2C so plan your pinout carefully before making a PC board. I've sidestepped the GPIO pin-count issue by going serial to the nixie drivers (74CH595+NPN current limiter). In the end, though, my b7971 project uses direct-drive. https://learn.sparkfun.com/tutorials/raspberry-gpio -- You received this message because you are subscribed to the Google Groups "neonixie-l" group.
