Robbert t's controlling a bunch of lights by using the Adafruit breakout board for the TLC59711
If you are on Bela, you will find that you have no "hardware" SPI port available to control your chip. There is a 100kHz "soft-SPI" interface available, but the performance of this will be heavily dependent on the CPU load, as it is effectively bitbanging the SPI protocol on a GPIO. BelaMini, on the other hand, does have a spare SPI hardware port to use with it.
If you are on Bela, you may consider using an i2c device, such as the PCA9685 successfully used here.
