I use PSOC3 to do ADC->DMA ->Memory to sample my analog input data then post- processing my ADC data.
ADC( 300K sps, 10 bits) Memory (xdata, ADC_data).
I try to modify some c codes from DMA example projects, but I did not get right sample data from ADC.
Here is my c code:
CyDmaTdSetAddress(td,ADC_DelSig_1_OUTSAMP, (uint16)&ADC_data );
Anyone knows how to do it?
Here are some modifications that should be done to make this work .
1) TD_SWAP_EN : Since the buffer - ADC_data(Big Endian) and ADC registers(Little Endian) have different endian-ess , you need to enable swap to store data in the proper format
2)ADC Coherency : By default the ADC coherency key is set to low. But in this case(When you read multi bytes from ADC register using single Td) , the last byte read will be mid byte. Hence you need to set the ADC coherency to mid byte .
3)"ADC_DelSig_1_OUTSAMP" is not an address but it is the value of ADC_DelSig_1_DEC__OUTSAMP register.
There are many such typos in the function used above - the compiler will give you error for other typos and you can correct it yourself.
