Embed File component

A component to simplify the process of embedding files into ROM. Stores the file inside a ROM look up table.

Detailed description

Examples

Basic example program which embeds a text file into the microcontrollers ROM memory and then prints the file out to a LCD display. EmbedFileExample Text file to go with the example, must be placed into the same directory as the Flowcode file.

File:TextFile.txt

Here is an archive which packages the example and text file together for you.

Embed File Example Files

The file is selected using the File component property.

Clicking the small arrow to the right of the property and selecting Browse allows you to select a file using a Windows file explorer.

Downloadable macro reference

	GetFileByte
Reads a single byte from the file at the specified address.
- UINT	Address
Address range 0 to NumBytesInFile - 1
- BYTE	Return

	GetFileLength
Returns the file size in bytes.
- UINT	Return

	SetByteArray
Writes an array of bytes to the EE memory.
- UINT	Address
Starting address of the first value to write
- BYTE	Data
- BYTE	Count
Number of bytes to write to the EE memory, Range: 1 to 128 bytes
- VOID	Return

	SetInt
Writes a 16-bit value to the EE memory. For consecutive 16-bit values the address must be incremented by 2.
- UINT	Address
Address of the value to write
- UINT	Value
16-bit value to write
[[File:]] -	MSBFirst
0: LSB is the first byte, 1: MSB is the first byte

	AddressSpecificDevice
Starts a temperature conversion on a specific device using a hex string identifier. SerialNumber parameter should be 12 characters and contain the 48-bit Serial.
- STRING	SerialNumber
48-bit Serial Number e.g. "32DF4A3C1901"
- VOID	Return

	GetSerialString

32-bit value to write
[[File:]] -	MSBFirst
0: LSB is the first byte, 1: MSB is the first byte
- VOID	Return

	GetFloat
Reads a 32-bit floating point value starting from the specified byte address. For consecutive float values the address must be incremented by 4.
[[File:]] -	Address
The starting byte address
[[File:]] -	MSBFirst
0: LSB is the first byte, 1: MSB is the first byte
[[File:]] -	Return

	GetLong

- BYTE	Data
- VOID	Return

	GetByte
Reads a single byte from the selected address.
- UINT	Address
Address of the value to read
- BYTE	Return

	SetFloat
Writes a 32-bit floating point value to the EE memory. For consecutive float values the address must be incremented by 4.
- UINT	Address
Address of the value to write
[[File:]] -	Value
Floating point value to write
[[File:]] -	MSBFirst
0: LSB is the first byte, 1: MSB is the first byte
