Hello,
I am currently working with the STEVAL-L99615C evaluation kit and the Nucleo G071RB microcontroller board. My goal is to set up a LabVIEW program that can:
1. Adjust the output voltages of power supplies to simulate real battery cells.
2. Read data measured by the evaluation kit (e.g., cell voltages).
For this, I need to learn the basics of communication with the evaluation kit, such as reading and writing to registers (e.g., reading VCELL1_MEAS from register 0x04).
Steps Taken So Far
1. I successfully connected the evaluation kit to the provided STSW-L99615C GUI, and it works as expected for executing scripts and reading data.
2. I attempted manual serial communication with the Nucleo G071RB using PuTTY:
Port Settings:
Baud Rate: 9600 (also tried 115200)
Data Bits: 8
Parity: None
Stop Bits: 1
Flow Control: None
Commands Attempted:
READ 0x04
READ 4
READ 4\n
READ 0x04\n
However, I did not receive any response from the board in PuTTY. Additionally, I observed that my keystrokes were not echoed, so I enabled local echo, but it still didn't resolve the issue.
Request for Assistance
Could you please assist with the following:
1. What is the correct command syntax for reading registers via serial communication?
2. Is there a specific protocol or handshake required before sending commands?
3. Are there any firmware configurations or prerequisites to enable manual serial communication?
4. Should I be using any particular baud rate or terminal settings to communicate with the kit?
Any guidance, documentation, or examples would be greatly appreciated.
Thank you for your time and support.
Best regards,
Jan Horak
