Hi Anton,

Could you please check whether the board is connected to a USB2 or USB3 port when doing the programming?

The utility requires a USB3 port in order to program the device and the error from a USB2 port looks the same as the one you mentioned here.

The board can be recovered by connecting to a USB3 port and repeating the programming and should then show up correctly programmed with your new settings.

Best Regards

Hello,

All our software examples use the 8051 Digital I/O ports P1 and P3 or Analog I/O ports P0 and P2. The pull up/downs are only relevant to the pins when they are inputs, and like the 8051 the pins are open drain when set as outputs.

Also note that traditional 8051 Port 0 (P0) is open-collector, unlike the other ports (P1 to P3).
This means that an external pull-up is required when using P0 as GPIO for example.

Thanks,

Some of our customers are having problems with Driver Reseller Rights for our submission ID 1152921504627044695.
 
When they open the .hlkx files in HLK Studio, the following error appears:

"Package (Shell_1152921504627044695.hlkx) with a version (3.4.0.0) is not compatible with this instance of PackageManager.  This instance of Package Manager accepts versions 3.3.0.0, 2.0.0.0, 3.1.0.0, 3.2.0.0"

This appears to be a problem with the latest version of HLK Studio version 1703:

https://developer.microsoft.com/en-us/windows/hardware/windows-hardware-lab-kit

If you download 'Get the HLK Insider Preview' at the link above, the issue is resolved with this preview version.
Note: You need to be a member of the Windows Insider program to download this preview version.

Microsoft plan to release this updated version of HLK Studio.

Note: The current free version of Visual Studio is Visual Studio Community 2017.
It allows you to use for 30 days without a Microsoft account. However, after this period it asks you to sign in. You can create a free Microsoft account which will allow you to continue to use Visual Studio for free.

The following simple code can be used as a test:

#include "stdafx.h"
#include <windows.h>
#include "ftd2xx.h"
int main()
{
FT_HANDLE ftHandle;
FT_STATUS ftStatus;
ftStatus = FT_Open(0, &ftHandle);
ftStatus |= FT_SetUSBParameters(ftHandle, 4096, 4096); // Set USB transfer sizes
ftStatus |= FT_SetChars(ftHandle, false, 0, false, 0); // Disable event characters
ftStatus |= FT_SetTimeouts(ftHandle, 5000, 5000); // Set read/write timeouts to 5 sec
ftStatus |= FT_SetLatencyTimer(ftHandle, 16); // Latency timer at default 16ms
ftStatus |= FT_SetFlowControl(ftHandle, FT_FLOW_NONE, 0x11, 0x13); // No flow control
ftStatus |= FT_SetBaudRate(ftHandle, 9600); // Baud rate = 9600
ftStatus |= FT_SetDataCharacteristics(ftHandle, FT_BITS_8, FT_STOP_BITS_1,
FT_PARITY_NONE);
if (ftStatus != FT_OK) printf("ftStatus not ok %d\n", ftStatus); //check for error
else
{
char data_out[12] = "Hello World";
DWORD w_data_len = 12;
DWORD data_written;
ftStatus = FT_Write(ftHandle, data_out, w_data_len, &data_written);
char data_in[12];
DWORD r_data_len = 12;
DWORD data_read;
ftStatus = FT_Read(ftHandle, data_in, r_data_len, &data_read);
if (ftStatus != FT_OK)
printf("ftStatus not ok %d\n", ftStatus);
else
printf("Data Read: %s\n", data_in);
}
ftStatus = FT_Close(ftHandle);
printf("Press Return To End Program");
getchar();
return 0;
}
