Implementing adc on cyclone 5

Hi Maheshbimaq,

1.In signaltap are you able to see the input signal? Check the input source.

2.In signaltap have you set trigger conditions?

3.ADC_SCK PIN_V10, ADC_SDO PIN_AD4, ADC_SDI PIN_AC4 & ADC_CONVST PIN_U9.

implemented the module according to manual i was able to run the program successfully but i am not able to find the output

may be i assigned the pins in wrong way can anyone suggest me to which pin i should assign the following adc_sclk and adc saddr , adc cs and adc sdat

thank you

This depends on what board you are using. Refer to the manual provided by the manufacturer (likely Terasic). They list all the FPGA pin connections for on-board devices.

thank you for your reply!

do i need to set this trigger condition after i mount my output file(sof) on FPGA?

can you tell me how to set the trigger condition because i am new to this tool and do you have any material for this so that i can learn

i have done the pin assignment correctly the problem is i am not able to set the trigger condition i dont have any experience with this tool so it will be easier for me if have any manual or steps to follow

so please could you help me

Hi

Go through the user guide of signal-tap for more information also check the below links

so in was able to see my nodes on analyzer....can you suggest me which condition should i give to see the output

Hi,

Understand the hardware and user manual.

Trigger on the clock at which ADC Data is changing/sampling.

or

trigger the data itself(led(0..7)) for checking it.

i want to read a analog input on 2*5 adc header i followed the module ....in the manual it says use pot (variable resistor) and it says run test.bat file but when i do it shows some value from channel 7 but i have connected to channel 0 of adc or can you tell me if i am going wrong ?

my question is how do i change it to channel 0

?

Hi

Have you "Set SW[2:0] = 000, to measure channel 0 of ADC"?
