I am controlling 16x16 RGB LED using TLC6983.
9Mhz PWM clock is continuously sent to the SCLK input, and data is written using SPI dma in synchronization with this clock source.
When the MCU simply performs the above operation, the LED display is normally displayed.
However, I want to update the display data by receiving data through the uart, but the display is intermittently broken when the uart interrupt comes in.
It seems to be caused by the spi data delay while the clock signal is continuously generated with SCLK.
Is there any way to solve this problem?
