Converted a driver for TLC95711 pwm board which uses SPI. I got it working fully with one weird issue when I have to rpio.Open() within the same function when I am writing to SPI.
With that being said, I found an issue when looping though colors and sending it through SPI, I am getting a "memory issue" according to the panic that gets thrown. I figure it's being caused when writing to SPI while a previous write hasn't finish being sent just yet. I have set up sleeps but you really can only delay so long before effects don't look right.
Would it be possible to add Locking capabilities similar to Arduino?
