Hello,
I am trying connect +4 LED1202 Driver in Daisy chain common clock domain configuration.
(Refereing to LED1202 Datasheet Revision 2, DS12875 - Rev 2 )
Under Section "6.2 Cascading multiple devices" and "Figure 23 Concept of daisy chain common clock domain configuration" is a schematics for 4 LED Driver
But I am not sure how the schematics should look with +4.
"Figure 24. Command sequence example for daisy chain common clock domain configuration" describes the implemention conecept for 8 LED Driver, but there are unclear instructsions in there.
"•Set MCU GPIO G to SCL and GPIO F to GND"
Does it mean that I should reconfigure the I2C SCL line from the MCU ? But what happens on the original SCL line ? (Does the LED1202 accepct SCL on A0/A1 pins ?)
Or should the I2C SCL line be mirrored to GPIO G? (I am not aware that pheripherials of MCUs are capable of this)
