Schematic
Power supply
ZL31ARM is powered from computer's USB port, PWR LED indicates whether board is supplied.
Board layout
Joystick
ZL31ARM is equipped with 5-position joystick. All joystick lines have pull-up resistors.
Joystick to microcontroller connection
| Position | Microcontroller line |
|---|---|
| Up | PC0 |
| Right | PC3 |
| Botton | PC1 |
| Left | PC2 |
| Enter | PB5 |
LEDs
ZL31ARM board is equipped with two LEDs (lit by low logic level).
LED to microcontroller connection
| Dioda | Microcontroller line |
|---|---|
| LED1 | PB1 |
| LED2 | PB2 |
Analog potentiometer
ZL31ARM board is equipped with P1 potentiometer, that controls voltage (0-3.3V) on microcontrollers ADC input (PB0 line).
I2C connector
ZL31ARM has Con7/I2C connector for external devices with I2C bus. SDA (PB7) and SCL (PB6) lines have pull-up resistors.
SPI connector
ZL31ARM board is equipped with Con6/SPI connector for external devices with SPI bus. All SPI lines have pull-up resistors.
SPI lines are connected to the microcontroller as described below
| SPI line | Microcontroller line |
|---|---|
| SS | PA4 |
| MOSI | PA7 |
| MISO | PA6 |
| SCK | PA5 |
I/O pin headers
Some I/O lines are connected to Con1, Con2, Con4 and Con5 pin headers. Every pin header has also +3.3V and GND pins.
Programmer/debugger (ST-Link)
Part of ZL31ARM is programmer/debugger with USB interface. Programmer is compatible with ST-Link by STM, it is supported by following IDEs:
- Keil μVision
- IAR Embedded Workbench
- Atollic TrueSTUDIO
- STMicroelectronics STVP
- STMicroelectronics STM32 ST-Link Utility
Out of the box programmer is joined to evaluation board, but it can be broken off and used with other STM32 evaluation boards. To use programmer as separate device you need to equip it with JP1 pin header (1x6 pin) to connect it to programmed devices. Evaluation board can be equipped with JP2 pin header, that can be connected pin-to-pin to JP1. PRG LED indicates programming.
