58.11. SEI Slave: Simulate TAMAGAWA Encoder

58.11.1. Overview

  • This demo shows SEI interface simulate TAMAGAWA encoder and generate position data, then print related information by uart console.

  • The simulated TAMAGAWA encoder is TS5700N8401。

58.11.2. Configuration

  • Prepare a USB to 485 module (Note: The maximum baudrate of this module must not be less than 2.5Mbps)

  • Connect SEI pins DATA_P/DATA_N to 485 module pins A/B

58.11.3. Running the example

  • Download and run the program in the development board.

  • Use PC serial debugging assistant to communicate with the development board, obtain simulated encoder data.

  • Set PC serial debugging assistant: baudrate-2500000, startbits-1, databits-8, stopbits-1, paritybits-none.

  • Use PC serial debugging assistant send Hex data: 1A or 02 or 8A or 92, the development board will response. Meanwhile, the console shows the following log. ST’s value increasing by 1 each sample.

  • Use PC serial debugging assistant send Hex data：32 7F 01 4C，which will set EEPROM page number to 1，the development board will response. Meanwhile, the console shows the following log.

Change EEPORM page to 1

  • Use PC serial debugging assistant send Hex data：32 01 5A 69，which will write data 0x5A to address 01 of EEPROM，the development board will response. Meanwhile, the console shows the following log.

Write EEPORM - Page: 1, Addr: 1, Data: 90

  • Use PC serial debugging assistant send Hex data：EA 01 EB，which will read data from address 01 of EEPROM，the development board will response. Meanwhile, the console shows the following log.
