LGTasp

USBasp/USBisp module for the LGT8F328P and AVR boards.

I created a small module to be able to program both LGT8F328P and AVR based Arduino boards without the hassle of a bunch of jumper wires, caps on RST, Linux permissions for the USB devices etc. It is basically a proMINI32 with a shield on top that has connectors to plug in a CP2102 UART board as well as targets such as the Nano32, proMINI32, AVR Nano and the AVR proMINI. Actually most any AVR board could be programmed - it features an Arduino ISP connector but may need jumpers due to the mechanical layout..

This README is intended to serve as an Operation Manual for the LGTisp module.

HARDWARE

The basic hardware consists of a proMINI32 with female headers installed to accept this module as a sheild. The sheild fits atop the proMINI32. Here are a couple of lousy photo which may or may not help in visualizing the programmer. ( rev 0 boards picture )

......

Basic Operation:

plug in a CP2102 board and either a LGT board or an AVR board.. Setup the Arduino IDE for the target board as follows:

LGT boards:

pay attention to the variant - the SSOP-20 has the serial I/O on different pins. Set the Arduino as ISP option to "Default(64)". select the AVR ISP programmer.

AVR boards:

setup the IDE as usual for your board - select the Arduino as ISP programmer.

here are some more lousy pictures... (not worth 1000 words but maybe 40-50...) NOTE: the AVR proMINI installs with only 1 row on pins inserted - the row with D12 and D13, VCC and GND etc. It is OFFSET by 1 pin on either end.
