This repository contains the design files of my business card.

The card is based on an MSP430G2553 microcontroller, which is programmed to blink an LED in a pattern and transmits a message via NFC.

This repo contains various code samples for the MSP-430G2 launchpad. The processor seems reasonably low-cost for most applications and is reasonably low-cost, when in-stock.

• Low cost
• COR in Malaysia
• Good documentation
• C++ support through GNU toolchain
• Mature user community
• Can buy direct from TI

• 16-bit ALU, slow compared to ARM
• Proprietary debug interface
  • not scriptable with OpenOCD
  • no Semihosting support
• Proprietary toolchain by default
  • Allegedly better optimized than comparable GCC toolchain
• No dedicated Systick timer
• No device with crystal-less USB device operation
  • Budget +$0.3 compared to crystal-less alternative

• Install MSP430GCC, MSPFlasher
• Make sure the tools are in PATH

# Build all sources
meson build --cross-file meson.ini
cd build
meson -v -C build compile
# Flash sources to target
meson compile flash_<sample_name>

• See Hardware for the required peripheral connections.
