Got two GUIDs for my device that Fx2LP cypress chip. Not sure why one of them is not working with a non .Net app like c++ but it works with a .Net app?. The GUID used in .NET, in c++ does not see my devices but with .Net it sees them but the other one works with the c++.
Hello,
I am very new to cx51 world. How to make external device like FPGA to have access to external memory of cx51?. FPGA should see any update made to the external memory of 8051.
using interrupt in 8051 how to execute series of somehow continuous commands as they arrive through the Rx pin?. Let's assume "unsigned char buffer[128]" is available. A command is composed of 11 bytes, with the first byte being the command identification. After each execution, three bytes 0x123...
what 8051 interrupt 15 is?. What kind of interrupt is it?. Is it a low priority 1 HZ timer?. Are there sample codes implements different interrupts. Any docs that simply explain all the 8051 interrupts?.
I have a third party code with declarations, something like:
#define LastByte as 0x32
unsigned char xdata ArrayTwo[0x10] _0x128_
Some where in the project I noticed: ArrayTwo[LastByte] = ...
Is this possible?. How LastByte can go beyond 0x10?. It runs without a crash. I am not a x51 programmer...
in the micro controller side , how the fields below are filled from the incoming bytes?:
typedef struct usbRequest{
uchar bmRequestType;
uchar bRequest;
usbWord_t wValue;
usbWord_t wIndex;
usbWord_t wLength;
}usbRequest_t;
8-O
In my keil program, during the run time I like in my code to check a value and come up with the following:
depending on a variable, var1 , bypass one of the settings[] in below.like if var1 = 1, the settings would be the first one and if var = 2,the settings would be the second one.
struct SS...
PC expects the data in binary format. sendbinaryBytes, sends the bytes in binary format. sendbinaryBytes sends four binary bytes and PC gets 4 binary bytes.
let say my uC code has a function:
void sendbinaryBytes (unsigned char b[4])
{
Serial.writeToPC(b[0],4);
}
using sendbinaryBytes function, how to send 1.764 to PC RS232?. also, in PC upon getting the binary bytes, how to display it as 1.764?. any examples..? you can modify the sendbinaryBytes...
