3.1.28：Automated machine

The current series of PowerWriter programmers (excluding PWLINK2) all support programming for Kingtung brand machines.

PWLINK2 only supports in-circuit programming, and for machine programming, it is recommended to use PWX1.

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.

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)
