I need a few LS7184N Quadrature Decoder ICs, and they are a bit tricky to get hold of in the UK. If I can get 10 or 20 delivered from the US, is there anybody in UK who wants one (or more) and will pay £9.00+pp for these excellent HW decoders...

Hi there, I am in a bit of a muddle with interrupts on Picaxe 28X2. I know there are three hardware interrupt pins: hint0, hint1 & hint3. I also know that I can set up an interrupt response within a 'gosub' for an arbitrary Hi/Lo combination of these 3 faults. Is it possible to setup a...

Hi there! I am designing a PCB for a fully tested circuit. I found an EDA Symbol for the PICAXE chip, or at least I thought I could use the Microchip PIC18F25K22-xSP Symbol (below). However - after completing all other parts of the circuit I just noticed that pin 19 is missing! Does anybody...

Hi all, I'm a bit confused - hope someone can help. I want to use SPI for output only. Do I need to connect the 'hspi sdi' pin (which is C.4 on a PICAXE-40X2)? I read that: "Due to the internal operation of the microcontrollers SPI port, a hspiout command will only function when the hspiin...
