►Quick Detail:

Thank you for browsing our company's products. This product is the Monitor SD Card Reading And Writing Module on the Biolight A5 patient monitor. The model is A8SD02 PN13-031-0012

The most common SD card module on the market has six pins, and the six pins are:

Ground is the ground pin of the micro sd card module and should be connected to the ground pin of the Arduino.

VCC is the power pin of the micro SD card module and can be connected to 5V or 3.3V power supply.

Miso represents the entry and exit of the Lord. This is the SPI data output by the SD card module.

Moxi represents the main exit and follow-up. This is the input pin of the SD card module.

SCK stands for Serial Clock, which as the name suggests is the data synchronization pulse generated by Arduino.

WeChat ID: MX-1861

CS stands for Chip Select, this pin can be controlled by the Arduino to enable or disable the module.

►SD card operation steps:

The reading and writing of the SD card depends on the situation. Although each reading and writing is in blocks, the instruction addressing of the SD card is different. The instruction addressing is the parameter part of the command. The size of each block during reading and writing can be Set via CMD16, the default is 512 bytes
The specific operation sequence is as follows

1. Send write command

2. Send multiple clocks

3. Send start flag 0xfe (single block) or 0xfc (multiple blocks)

4. Send 512 bytes continuously

5. Send the last 2 bytes CRC (0xff)

6. The read byte is ANDed with the 0x05 bit. When it is 0x05, the transmission is successful.

7. Repeat steps 2-6 when you need to send continuously, and send 0xfd when you finish writing multiple blocks.

Continue reading continuously until it is not 0xff, and the SD card completes the writing operation.
