Hi, I have problems to run pl1000 SDK routine(s) implemented in C++ Borland code.
Execution under C Borland, instead, works nice.
Code much similar that of routine "void collect_windowed_blocks (void)",-line397-, in "pl1000Con.c" SDK Pico example with:
A)two little adds,
B)/*WathList_{1|2|3} inserted for variables: status=... ; g_handle=... ; channels[]=... ; nChannels=....
in execution points:
Code: Select all
int16_t g_handle;
int16_t isReady;
PICO_STATUS status;
status = pl1000OpenUnit(&g_handle);
int16_t channels [] = {(int16_t) PL1000_CHANNEL_1, (int16_t) PL1000_CHANNEL_2 };
uint32_t nSamples = 1000; // Should be equal to nChannels * nSamplesPerChannel
int16_t nChannels = 2;
/*WatchList_1: status=0 ; g_handle=16384 ; channels[]={1,2} ; nChannels=2 */
uint32_t nSamplesPerChannel = 500;
uint32_t nSamplesCollected;
uint16_t* samples = (uint16_t*) calloc(nSamples, sizeof(uint16_t)); // Size of array should be equal to nChannels * nSamplesPerChannel
uint32_t usForBlock = 1000000; // 1s
uint16_t overflow = 0;
uint32_t triggerIndex = 0;
uint32_t samplingIntervalUs = 0;
// Set the trigger (disabled)
status = pl1000SetTrigger(g_handle, FALSE, 0, 0, 0, 0, 0, 0, 0);
/*WatchList_2: status=0 ; g_handle=16384 ; channels[]={1,2} ; nChannels=2 */
// Set sampling rate and channels
status = pl1000SetInterval(g_handle, &usForBlock, nSamplesPerChannel, channels, nChannels);
/*WatchList_3: status=16="PICO_NULL_PARAMETER" ; g_handle=16384 ; channels[]={2,51} ; nChannels=0 */
samplingIntervalUs = (usForBlock / (nSamplesPerChannel * nChannels));
// Run
status = pl1000Run(g_handle, nSamplesPerChannel, BM_SINGLE);
// Wait until unit is ready
isReady = 0;
while(isReady == 0){
status = pl1000Ready(g_handle, &isReady);
}
nSamplesCollected = nSamplesPerChannel;
status = pl1000GetValues(g_handle, samples, &nSamplesCollected, &overflow, &triggerIndex);
status = pl1000Stop(g_handle);
/* free memory */
free(samples);
/*WatchList_3: status=16="PICO_NULL_PARAMETER" ; g_handle=16384 ; channels[]={2,51} ; nChannels=0 */after call pl1000SetInterval() function, the array channel[] change in elements and dimension.
Obviously these variables assume random value between more launch program.
Furthermore, the return status of pl1000SetInterval() function assumes error code 16 (0x) with "PICO_NULL_PARAMETER" meaning.Qual è il pasticcio?
Qualcuno mi aiuti, per favore.
Grazie,
Michele.
