Alternative to AXE027 USB Cable
May 7, 2012
One place where the "going got rough" with regards to my (Argentine) Picaxe Developer Site is with a Picaxe serial download cable that IS NOT RS-232, but USB instead.
If I can only reach those with a serial port on their PCs, then this project will never prosper. USB is a MUST.
Revolution Education sells a very nifty USB-to-miniplug cable together with drivers et al., known as AXE027. Unfortunately, at £10 a pop and being located in Great Britain, when they finally get here, they would be more expensive that the protoboard itself. Completely beyond the point, if you ask me.
In the local market there are a bunch of DB9-USB adapters. I have purchased a few, but none of them worked inside the Picaxe environment. I am at a very critical stage. If I can´t find a way around this, I will have to take the site off-air until I can figure something out.
I have learnt that the trick lies inside the chipset that interprets one protocol into the other. Apparently the AXE027 uses an FTDI one, with inverted logic. Has anyone out there had any luck with anything other than the AXE027? If you could please share your experiences with me, I would be forever grateful.
