3.5.1：Automated machine

PowerWriter's current series of programmer (except PWLINK2) all support automated burner wiring, such as: KINCOTO , etc., the machine signal wiring is more or less the same. PWLINK2 only supports the online burner function, the machine burner recommended to use X1.

1.Signals of the PowerWriter:​

  • CTRL: Controls the start of low-pulse programming, which requires the input of a low-pulse signal greater than 40ms and less than 1s to start offline programming once.
  • OK: outputs high when the programming is successful, outputs 5V, and clears the state to low when there is a new operation.
  • NG: Outputs high when the programming fails, outputs 5V, and clears the state to low when there is a new operation.
  • 5V: Machine interface power supply pin (please do not connect VREF).
  • GND: Ground.
  • (*) BUSY: Busy signal: Outputs high during burning, and low at the end.
  • (*) EOT: Transmission end signal: Low level during burning, high level at the end of transmission.
note

The BUSY and EOT signals are non-essential signals and are only included in some device versions.

Both OK and NG output low at 0V for idle and busy states.

CTRL and key logic are the same, when starting the CTRL signal is equivalent to manually pressing a key, the programmer enters the busy state, and the OK and NG lamps will go out.

2.Signals of the Machine:​

  • START: LOW(the same as CTRL)

  • OK:HIGH

  • NG:HIGH

  • BUSY:X(Since the PowerWriter does not have a busy signal exposed, you can leave that signal pin unconnected and set it to X; this will not affect the programming.)

For other parameters on the machine, there are no special considerations. Set them according to the previous production requirements.

3.Connection​

PowerWriter to Machine:

CTRL--- START;OK---OK;NG---NG;GND---GND;5V---VDD(the power of machine)

PowerWriter to MCU:

SWDIO---SWDIO;SWCLK---SWCLK;GND---GND;VREF---VDD(the power of MCU)
