EEPROM Pogramming in STC microcontroller

Chun Hou — Tue, 26 Jul 2016 15:54:00 +0800

Currently i was having problem in getting the result in programming the STC. More precisely, the EEPROM part of the microcontroller, the internal EEPROM. The demo code is at page 374~377. I having an error after clearing all the EEPROM data, first time checking whether the value is giving ffH value shows an error (jump to the error loop). It should be correct, but... I have no idea why there is an error shown. I think i miss something, can anyone pls help, TQ.

Data Transfer for Bluetooth Device UWP

Chun Hou — Fri, 15 Apr 2016 17:23:40 +0800

I have been successfully connected my bluetooth device. Now problems come, i can't get the data from my device, it is a string type data. This is the first code i tried in getting the data which i copy from here, https://channel9.msdn.com/Events/Ignite/Aus...lia-2015/MOB222 :

while (true)
{

var disdata = await this.ReadDistanceAsyncsocket (reader);

await this.Dispatcher.RunAsync(CoreDispatcherPriority.Normal, () =>
{
this.display.Text = reader.ToString();
});

i know the red one is a function but from the video i am not able to get the function. So, i wanna ask if any of you know to get readable data??

Then, i tried another code, which is direct copy from microsoft developer resource, https://msdn.microsoft.com/library/windows/apps/br208119:

var stream = new Windows.Storage.Streams.InMemoryRandomAccessStream();
using (var inputStream = stream.GetInputStreamAt(0))
{
using (var dataReader = new Windows.Storage.Streams.DataReader(inputStream))
{
// The encoding and byte order need to match the settings of the writer
// we previously used.
dataReader.UnicodeEncoding = UnicodeEncoding.Utf8;
dataReader.ByteOrder = ByteOrder.LittleEndian;

// Once we have written the contents successfully we load the stream.
await dataReader.LoadAsync((uint)stream.Size);

var receivedStrings = "";

// Keep reading until we consume the complete stream.
while (dataReader.UnconsumedBufferLength > 0)
{
// Note that the call to readString requires a length of "code units"
// to read. This is the reason each string is preceded by its length
// when "on the wire".
uint bytesToRead = dataReader.ReadUInt32();
receivedStrings += dataReader.ReadString(bytesToRead) + "\n";
}

// Populate the ElementsRead text block with the items we read
// from the stream.
display.Text = receivedStrings;
}
}

But this one worst, i don't even get anything from it. I am sure it is my problems, but i don't where is the problem. May any one please point it out for me??
Thanks, i have been headache for few days stuck here..
