Other Parts Discussed in Thread: TLC5944, , TLC5946
Hi there,
I have 24 different LEDs (5 red, 5 blue, 5 green, 4 white, 5 orange) that need between 8-20mA, depending on the LED colour. I would like to use the 24 channel, 30mA TLC5947 to power them and use PWM to change the current as it turns on different coloured LEDs. Each colour of LED is turned on at a different time (ie. all red on, then off, then all green on, then off, etc.). I also have 5 UV LEDs that need 55mA of current. I would like to use the 60mA TLC5944 to power those. I am using a raspberry pi 3 A+ to control the LEDs. I was wondering if:
(1) I can cascade the TLC5947 and the TLC5944 to achieve my design? Do they have the same control mechanism (ie. I can use the same cascading wiring configuration and the same code to control it)? If not, do you have another suggestion as to how I should power these?
(2) There is a readily available python library for me to code the two devices with my raspberry pi?
Thanks!
