MS_8ADCPWM

Board with 2x ADS8688a chips (8 analog inputs each) and 1x TLC5947 chip (24ch LED PWM driver).

Issues when chaining more than 4 boards (8 ADS8688a ics)

next iteration

• digital buffers, to allow larger chains
• default-off on LED channels, in the absence of control signal
• power-in with screw terminals?
