350LCD Revision C Programming Instructions

Gather the requirement and follow the setup procedure. Then run all the three programming stages. The whole programming process is successful if all the three programming stages are successful.The following diagram can help you to locate the connectors and devices on the PCB.
Note:In all programming stages first connect the programmer to the board then power it up and also at the end of the programming first power off the board and then disconnect the programming cable.
CAUTION:High frequency energy present when powered. Touching anywhere in the caution area could result in a Radio Frequency (RF) Burn.
Now connect the GND and 12V connector to the power supply and verify the four specified voltages in the following diagram and then turn off the power.

1. AtmelStudio 4 or above.
2. FLASH PROGRAMMER from http://www.macraigor.com/swproducts.htm.
3. ispVM System Version 17 or above from http://www.latticesemi.com/products/designsoftware/programmer/ispvmsystem/index.cfm
4. Firmware archive file provided by E-Plex.

1. 12V Power supply.
2. “AVRISP mkII” programmer from Atmel included the USB cable.
3. Ribbon cable provided by E-Plex.
4. “usbWiggler debugger” from Macraigor Systems.
5. “HW-USBN-2A” ispDOWNLOAD Cable from Lattice Semiconductor.

1. Install AtmelStudio on the PC.
2. Install FLASH PROGRAMMER on the PC.
3. Install isp VM System.
4. Unzip the firmware archive file in the local drive of the PC.

1. Connect AVRISP mkII to the PC by a USB cable and J5 on the board by using the provided ribbon cable.
2. Apply 12V power supply.
3. Now you must see two-on grean LEDs on the programmer other wise there is an error.
4. Run the “350LCD V2.16 RevC.bat” in the unzipped-firmware folder provided by E-Plex Ltd and follow the prompts.
5. Ensure that there were no errors.
6. Disconnect Power (+12v) first and then disconnect the AVRISP mkII Programmer at this time.
