This demo is based on the GD32150R-EVAL/GD32190R-EVAL board, it shows how to
|
|
configure and use the CEC peripheral to receive and transmit messages. In this
|
|
demo, the same program is loaded to two GD32150R-EVAL/GD32190R-EVAL boards,
|
|
then they are communicated through connecting respective CEC line(PB8) and GND.
|
|
When press the buttons(K3 or K4) on one board, LED1 and LED2 will blink once.
|
|
Connect two GD32150R-EVAL/GD32190R-EVAL boards through CEC line(PB8) and GND.
