ADC_DualModeInterleaved
stm32f4 adc 的代码,双通道,用DMA保存数据。(stm32f4 family c code, adc
This example provides a short description of how to use the ADC peripheral to
convert a regular channel in Dual interleaved mode using DMA in mode 3 with 5Msps.
DMA mode 3 is used in interleaved mode in 6-bit and 8-bit resolutions.
The Dual interleaved delay is configured 6 ADC clk cycles.
On each DMA request (two data items are available) two bytes representing two
ADC-converted data items are transferred as a half word.
The data transfer order is similar to that of the DMA mode 2.
A DMA request is generated each time 2 data items are available
1st request: ADC_CDR[15:0] = (ADC2_DR[7:0] << 8) | ADC1_DR[7:0]
2nd request: ADC_CDR[15:0] = (ADC2_DR[7:0] << 8) | ADC1_DR[7:0]
The ADC1 and ADC2 are configured to convert ADC Channel 12, with conversion
triggered by software.
By this way, ADC channel 12 is converted each 6 cycles.
In this example, the system clock is 168MHz, APB2 =84MHz and ADC clock = APB2 /2.
Since ADCCLK=)
