Hi everybody.\n\nI tried this tool but nothing seems to happen. The "Spectrum Display" does not show.\nMy pc is a win7 64 bit, on the same machine I run sdrplay+sdr# with no problem.\nCan anyone write 10 lines "guide" to start-up with this tool? TNX
I got issues with the decimal format in the API Evaluation Tool. \n\nI got the following message, in a popup, when the entries in the tool don''t match the setup in your regional setting.\n==============================================\nA non managed exception occur in your application.\nIf you clic continue, the application wll ignore this error and try to continue.\nIf you clic Quit, the application will stop immediately.\n\nThe input chain format is incorrect.\n==============================================\nMy regional setting in the control panel was set to "comma" for decimal seperator and was using "dot" in the API tool.\nI put "dot" in the regional setting ( it''s the normal format here in america ) then everything worked fine after that.\n\nHope it helped some of you.
I''m following your clear guide and also I''m trying with values in "Mirics SDR API Specification.pdf" page 10\n"... err = mir_sdr_Init(newGr, 2.048, 222.064, mir_sdr_BW_1_536, mir_sdr_IF_Zero, &sps); ..."\nwhere newGR=40 etc. etc. etc. \nso I input in the tool\n---> Frequency (MHz) 222.064\n---> Gain Reduction (dB) 40\n---> IF Bandwidth 1.536 MHz (drop down list value)\n---> IF mode ZIF (drop down list value)\n---> ADC Sample Freq (MHz) 2.048\nthen clic [Initialise]\nand I got Return code = 3 (out of range) ???\nAPI CMD display = mir_sdr_Init(40,2048,222064,3,0,&samplesPerPacket);\n(API EVALUATION TOOL ... in the right down corner i see V0.0.1)\nWHere am I wrong?
The API evaluation tool allows you to fire individual commands from the API to the device. The idea here is to show not only how the correct commands should look but also what they do. A typical sequence might be.\n\n1. Initialise the device. Set the desired frequency, gain reduction, IF bandwidth, IF mode and ADC sample frequency then hit the initialise button. The command is sent to the SDRplay module and is echoed to the API Command Display at the bottom.\n\n2. Once the device has been initialised you can then click the spectrum display to see the data being returned from the device. You wonâ€™t be able to see the display until the initialise button has been clicked.\n\n3. You are then free to fire any other commands at the tuner and watch the response. For example you might want to change the gain reduction. You can put the desired gain reduction in the gain reduction box say 20dB and then hit the Set GR button. You will see the command applied to the SDRplay module and again echoed in the Command Display window at the bottom.\n\nAs I said the idea here is to allow anyone who may wish to program the device to see how the correct commands should look and also to see their individual behaviour.\n
Is there still an SDR API Evaluation tool available? I didn't see it listed on the downloads page, and nothing turned up on an internet search. If so, does anyone know where could I get a copy?
