Hi expert,
customer use 941 connect two display, one use 926(480*240); one use 948(1920*720,dual LVDS), below is simply diagram:
we have below questions need your help:
1. I2S configuration. In this case, 948 need I2S while 926 needn't, so how to configure 941 side?
2. SPI configuration. 948 need SPI while 926 needn't , how to configure 941?
3. both 948 and 926 need INT signal,but 941 only have one REM_INT, how to assign INT in 941? is there need external GPIO singal as INT?
4. they set the back channel frequency of 926 to 5M and set 948 to 20M, Is there a conflict in 941 side?
5. because only one lane DSI input on 941, Is it only necessary to connect the REFCLK0 crystal oscillator, and REFCLK1 does not need to be connected?
6. for unused DSI of 941, how to configure the unused pin? Connect ground or left, which one is recommended ? customer care about power consuption if they connect to ground.
7. Since 941 connect two Deser, if customer want tansfer GPIO like PWM from 941 to 926, how to specify the GPIO is transfer to 926 rather than 948?
8. below output connector, customer would like use 1/3 tansmite 3.3V/5V switch signal, they have concern that if this will affact Dout signal quality.
Thanks in advance.
