SERIAL INTERFACE DEVELOPERS GUIDE 1 Introduction This guide has been written to help the developer become acquainted with and be able to develop around the Serial Interface Protocol requirements for the Embeddable Camera Electronics System hardware. An overview of the system requirements and a detailed description of the protocol are provided. This guide also provides information on how the Lumitron Operational Manager Application software interacts with the ECS-320A hardware during sy

SERIAL INTERFACE DEVELOPERS GUIDE used for text/file transfer. The bootloader is JTAG loaded into the DSP boot flash, typically during the production of the camera electronics. After the bootloader has configured the serial port it will output some text messages informing the host of its status and go into a wait state (approximately 5 seconds). During the wait state the host can initiate a file upload. Once a file upload is complete or the wait state times out, then execution is tran

SERIAL INTERFACE DEVELOPERS GUIDE When the trigger occurs the host application can begin writing the file data to the COM port. The bootloader receives the incoming data stream, converts the text data, and writes the executable to the proper location in DSP program and data flash. Once the file transfer is complete execution is transferred to the embedded application that was just loaded. Lumitron v0003 Bootloader Version: The latest bootloader version no longer uses a ‘Xon/Xoff’ proto

The remainder of the settings are automatically configured by the communications library. 5 Host Side Interface 5.1 Baud Rate The baud rate of the host side can be fixed to the configuration of the camera electronics or it can be designed to detect the active baud rate. When opening the port on the host application side the function requires a baud rate parameter. See funct

SERIAL INTERFACE DEVELOPERS GUIDE 5.2.5 McbReadDataMem Call this function to read a block of memory from the DSP. At the lower level the call may be broken into several calls to the DSP controller to read the entire block. This function can also be used to read registers or a block of registers that are mapped into the DSP data memory space. Function Definition: MCBCOM MCBCOM_API DWORD McbReadDataMem(HMCBCOM hCom, LPVOID dest, DWORD addr, WORD size); Note that the function parameter

SERIAL INTERFACE DEVELOPERS GUIDE 5.3.2 CMD_PROG_SFLASH_FULL Description: Program a full page to serial flash. The data to be programmed will need to be written to the scratch pad (DSP memory location 0x00C0) before initiating this command. The offset for the write into serial flash will be 0 regardless of the structure value. Command Code: Enumeration for CMD_PROG_SFLASH_FULL Argument Size: size of flash_XFER Argument: See below. struct _flash_XFER { WORD eraseFlag; // Statu

Command Code: Enumeration for CMD_IMAGE_GRAB Argument Size: UWord16 Argument: Buffer to be selected (0 – data placed in image grab buffer A, and 1 - data placed in image grab buffer B). Note: This command was included for debug and development and should not be used for normal operation since a write operation takes place. Buffers may be in use by real
