HI ST,
I do a project about MIPI DSI but have an issue:
- when send the first command DSI in command mode, status is HAL_OK and I see the signal on scope (DSI D0P/D0N). After that, Pin DSI D0P/D0N is in level 0 and don't send the next command.
DSI Config: DSI_Clock_land_byte = 38MHz, TXEscapeCkdiv = 0x09
PhyTimings.ClockLaneHS2LPTime = 35;
PhyTimings.ClockLaneLP2HSTime = 35;
PhyTimings.DataLaneHS2LPTime = 35;
PhyTimings.DataLaneLP2HSTime = 35;
PhyTimings.DataLaneMaxReadTime = 0;
PhyTimings.StopWaitTime = 10;
HAL_DSI_ConfigPhyTimer(&hlcd_dsi, &PhyTimings);
Please help me, thank you.
