This demo is based on the GD32W515P-EVAL-V1.0 board, it shows how to convert ADC
regular and inserted group channels using EXTI external triggers.
The inserted group length is 4, the scan mode is set, every rising edge event of
EXTI15 (PA15) will trigger ADC to convert all the channels in the inserted group. When
all inserted group channels are converted, EOIC Interrupt will be generated. The
inserted datas are print by USART.
The regular group is configured in discontinuous mode, group length is 4, conversion
length is 1, Every rising edge event of EXTI11 (PA11) converts 1 channel and DMA can be
used to transfer the converted data.
We can watch array adc_value[]/inserted_data[] in debug mode or by COM0.
Connect PA11/PA15 to key Tamper(PA2).
