Hello,
I am using STM32F407 to interface a MAX6969 led driver, MAX6969 is usually interfaced using SPI MOSI/MISO lines ..
The problem is!, I am out of connectivity protocols (I2C/I2S/SPI/UART) only USART left and some GPIOs!
Can I use USARTto interface MAX6969 which have DIN, CLK, LE, OE pins!?
Or should I just set remaining pins to be GPIO_Output use them to connect to MAX6969 pins (DIN, CLK, LE, OE)!?
Thanks,
