Pagina afdrukkenEXA-PROG
USB programming adapter for AVR-ISP, AVR-UPDI, STM32, LPC, ESP8266, ESP32
Connection of an NXP/LPC Controller
DIP SWITCH: 2 = OFF, 3 = ON, 4 = ON
NOTICES, TIPS:
In order to program the NXP controller, it must be supplied with 3.3 volts.
A crystal does not have to be connected to the NXP controller for programming. The controller's bootloader uses the
internal RC oscillator to generate the system clock.
Controlling the BOOT and RESET lines works very well with the tool "Flash Magic".
If you develop your own programming tool, the BOOT and RESET lines can be controlled via the DTR (!BOOT) and
RTS (!RESET) signals. This can also be done manually using the reset button on the EXA-PROG.
This programmer does not support 8-bit controllers (LPC9xx) and NXP controllers without an ARM Cortex core.
EXA-PROG as USB/Serial Converter
Connect the programming connector leads on the EXA-PROG directly to the
pins on the controller:
10 Pin Header
PIN1 (TXD)
PIN3 (BOOT)
PIN5 (RESET)
PIN9 (RXD)
PIN10 (GND)
optional:
PIN2 (VCC)
The pin numbers of the NXP controller vary depending on the shape of the case. Please check
out the data sheet in order to determine the pin numbers that match your controller.
DIP switch 1: must be set to OFF = 3.3V.
EXA-PROG can be used as a USB/serial converter in the modes STM32, NXP/LPC, and
ESP32.
The maximum transmission rate is 1 Mbit.
Supported as transmission parameters: 7 + 8 bit, Parity OFF, EVEN, ODD, 1 or 2
Stoppbits.
TXD (PIN1) gets connected to the RX pin and RXD (PIN9) is connected to the TX pin of
the microcontroller.
DIP switch 1: OFF = 3.3V, ON = 5V. Be sure to set the same voltage here your circuit is
running at.
