My Development System

Above is my current LocoDev development system.

• Top right is the Keypad/LCD using I picked up a while ago from a surplus electronics shop. Here is a close-up of the ribbon cable connection.
• Behind is my new genuine US$29 Atmel AVR ISP programmer. I finally had to give up with the MegaLoad Boot Loader, it's good but I was running out of FLASH memory space. I really needed a fast programmer that could attach via a USB to Serial port adaptor connected to my laptop. The AVR910 based programmer shown below is just too slow for development. There are a few other DIY options but I decided I wanted to spend my time doing LocoDev development not AVR programmer development.

Above is my previous LocoDev development system.

• Bottom left is the Sample Electronics PC Parallel Port ICSP programmer I used with my desktop PC.
• Bottom right is a Atmel AN910 based serial ISCP programmer based on a SIMM100 I got from Dontronics. The AN910 programmer is not as fast but it does work with my Laptop that only has USB ports.
• However most of the time I use the MegaLoad Boot Loader developed by Sylvain Bissonnette of Microsyl which is really quick!

Above is what I initially developed the LocoDev PCB with:

• Its based on a Dontronics DT006 that has an onboard Power Supply, RS232 Interface, a Simple ISP (In circuit Serial Programmer) that connect to the PC's Printer Port, Sockets for 8, 20 and 28 pin AVR devices and two SIMM sockets for SIMMSticks



• I mounted a Prototyping Board on Vero, with a strip of Machined Pin Sockets down each side and connected the Pins through to the DT006's SIMMStick BUS, an old 40x2 LCD display and an RJ12 wall socket for the LocoNet connection.



• I started using the 20 pin AT90S2313 that came with the DT006 kit, but it only has 128 bytes of RAM which you can use up real quick with C, so I upgraded to a 40 pin AT90S8535 that has 512 bytes of RAM and mounted it on a SIMM100 SIMMStick.
