Hello,I have a SEPLOS brand battery management system card, and I want to read temperature and voltage data from this card. Initially, I will use an STM32F407VGT6 board to read data from the SEPLOS battery management system card via RS485. I am sendi...

There is a device, and as far as I understand, the sent parameter does not cause a physical change in the system. Normally, telecommand data causes alarms or physical changes in the system, while telemetry data can only retrieve cell temperature and ...

Do you know how to manually set the address? For example, I manually keep the address positions at zero and send the command based on the address value 00. As far as I understand, the STM sends commands based on the data in Table 7. For example, afte...

Yes, I noticed that there is a problem here. The circuit I am using is the MAX485 module. In fact, there are more advanced modules that automatically switch between high and low. If there is an issue, I have also obtained those modules.

Yes, my first mistake was here. When sending a command, I need to set the pins to high position, and then when performing the receive operation, I need to set the DE/RE pins to low position. I hope this is the only problem. Do you see any other missi...

What I want to do is send telemetry data from the datasheet with the STM32F407VGT6 board and then read the 75-byte long temperature and voltage data. I have no issues with the data transmission process; it is successful. However, I am unable to read ...
