The JTAG/debug adapter for ARM/MSP430 is a feature‐rich multi‐mode programming and debugging adapter for embedded systems. Used with a standard J-Link or MSP-FET, the device offers three options to connect to your target without requiring expensive and/or large headers on the target device. Dual USB to serial converters can be used in conjunction with the programmer or standalone.
The Engenuics JTAG‐14 connection uses a 0.050” pitch 2X7 SMT connector. All JTAG /SWD signals are available along with two UART Tx/Rx pairs and a system tick input. Dual FTDI USB‐to‐Serial converters connect through to the target to access UART debugging with or without JTAG.
A Tag‐Connect 10‐pin header enables the same TC‐2050‐IDC cable to connect to ARM or MSP430 targets. Two unused lines are used to bring out one UART Tx/Rx pair for serial debugging.
For ARM devices supporting two‐line SWD programming, the adapter has a USB A connector with re‐purposed D‐ and D+ lines to connect to the target using a standard USB connector.
