Hello, I am using DLP FPGA kit which contains FT2232D chip. Data transfer is through parallel FIFO interface and D2xx driver. I have to transfer 3 bytes of data which is generated at different data rate in different scenarios.This 3 bytes of data is generated at X/Y rate in FPGA . Here X can have value of 5MHz, 7.5Mhz, 10 Mhz, 15MHz or 20 Mhz and Y will have value 256, 128 or 64.
But while reading through application i am seeing data corruption in few samples. Earlier i was using Driver CDM 2.04.6 in which many samples were getting corrupted. In the application i had Settimer which has counter of
100 ms.So continuously every 100 ms i was reading the samples . To avoid the data corruption in the application i used to Reset after reading 20480 bytes using command "FT_ResetDevice".But even in this 20480, first 750 samples will be corrupted .but always For option X/64 and X/128 data was corrupted after 10240 samples
main() { SetTimer(15,100, NULL)}
void CCStatsDlg::OnTimer(UINT nIDEvent) { status = GetQueueStatus(&bytes_in_buf); if(bytes_in_buf) { status = Read(rx, bytes_in_buf 0)) /* Read timeout */)
{ if(ret_bytes) { UpdateData(TRUE);
for(DWORD x=0; x
