\"\"<\/a><\/p>\n

Sean Hegarty has been in touch about a new HAT-format board that he and his company (CNC Design Ltd<\/a>) have released for the Raspberry Pi. It allows\u00a0clean, fast and accurate pulses to be created using simple ASCII commands. This is especially useful for “hardware designs\u00a0where a variable frequency pulse is needed, but one that is the most popular is for driving stepper\/servo motors that use pulse and direction lines”. It has an on-board Arm Cortex M4 processor running at 100MHz and dedicated direct digital synthesizer (DDS) pulse\u00a0generators with 0.004Hz resolution for each channel. The HAT stack is capable of up to 4 individual pulse train outputs and also has a bunch of other features that you can read about here<\/a>. The full package is \u00a355+VAT and you can get the boards from their website<\/a>.<\/p>\n","protected":false},"excerpt":{"rendered":"
