Interface description
1. SWD interface: support simulation, download and debugging.
2. Micro USB interface: power supply and USB communication
function, do not support download.
3. Usart1 interface: can be used for usart1 to download programs,
or use USA RT1 communicates.
4. MCU pin interface: lead out all I / 0 port pins to facilitate
connection with peripheral devices.
5. 5V and 3.3V power input and output interface: commonly used for
external power supply, or with other modules
Co processing was carried out.
Device description
1. Power LED (PWR): power indicator state 8, can judge whether the
power supply is stable.
2. User LED (pc13): convenient for IO choke test or indication of
program running status.
3. Select programming mode for boot hopping: (1. User flash 2. SRAM
3. System memory)
4. Reset button: used to reset the chip program.
5.8m crystal oscillator: the main frequency of the system can be
set to 72mhz by frequency doubling.
6.32.768khz crystal oscillator: it can be used for built-in RTC or
for calibration.
About Usage:
1. Use the micro USB interface to power supply (ordinary Android data cable can be used)
Development of toilet equipment
2. It has voltage regulator chip, which is convenient for level
conversion, and is connected with microusbr interface
If you need to use 3.3V voltage.The 3.3V pin on the
top provides power for the core board.
(pay attention to strictly forbid too much Power
input to prevent short circuit fault)
3. The double row needle of this chain is not welded by default for
the convenience of customer design and development Choose for
yourself.
4. Using SWD debugging interface, this interface needs three
interfaces to complete debugging and downloading.
Compared with the traditional JTAG debugging, it has
many advantages. (JTAG will be eliminated at present
For example, ST's new Mo system only retains the SWD
interface and cancels JTAG Interface)
5. In view of the problem that se32rtc does not vibrate, we adopt
the low load RTC crystal oscillator scheme.
