error 200877 when trying to change the sample rate

[mael15]

hi everyone,

i am not sure if this is the right forum. i develop a c++ program that should be able to change the sampleRate for a USB-6210. when i do this, i get a -200877 error (see attachment).

while the message explains a lot, a cannot solve the problem doing this:

DAQmxErrChk(DAQmxCfgSampClkTiming(getHandle(), nullptr, sampleRate, DAQmx_Val_Rising, DAQmx_Val_ContSamps, getDeviceConfig()->getScanBlockSize()));
uInt32 val = getDeviceConfig()->getScanBlockSize() * 125;
DAQmxErrChk(DAQmxSetBufInputBufSize(getHandle(), val));

what am i missing?

thank you!

Hi mael15,

I found one thread which is pretty similar to your problem:

Does this help you?
