Reading 1-Wire iButtons using Cypress PSoC 3 and 5/5LP

Previously I posted about using a standard UART to read and write to 1-Wire devices. In this post I look at how to read and write to these devices using Cypress PSoC devices. Continue reading

Using Creator v3.0 to target PSoC5 and PSoC5 LP

Recently Cypress updated their PSoC Creator tool suite to version 3.0.
V3.0 Brought with it some great new features, such as:

  • Auto Complete
  • Goto Definition
  • Code Explorer
  • Inline Diagnostics
  • Disabled code highlighting
  • Automatic indenting
  • And loads of other productivity and compiler improvements.

However as I have mentioned in this post before, the tool dropped support for the PSoC 5 Chip, which has been superseded by the fantastic new PSoC5LP Device. There are drop in replacements for every PSoC5 chip from the new 5LP Range. Cypress encourage developers to use the new 5LP devices in their new projects and when updating existing projects. The 5LP are pin and source-code compatible with the equivalent 5 Devices, but they are not binary code compatible. You need to rebuild your code with the new device selected in PSoC Creator.

But what do you do if you have an existing product, using PSoC5 devices that is out there in the field, all new boards that you manufacture should have 5LP on them, and you have to maintain and update the code on these boards? You cannot just build a project in the new tools and target the two devices – because the latest tools no longer support PSoC5, just the new PSoC5LP.
