Built for engineers working with technical documentation
See how engineers use ManualFlow to get answers from their documentation.
Embedded & Hardware Engineers
Working with datasheets and register maps
Example Query
“What's the I2C address for sleep mode?”
ManualFlow Response
Address 0x76 (SDO low) or 0x77 (SDO high). Sleep mode enabled by setting register 0xF4 to 0x00.
Network Engineers
Referencing protocol specs and system manuals
Example Query
“How does OSPF determine the DR on a broadcast segment?”
ManualFlow Response
Highest router priority wins. If tied, highest Router ID. DR election happens on first Hello exchange.
Technical Support Engineers
Answering questions from product documentation
Example Query
“What's the default baud rate for Modbus on EM300?”
ManualFlow Response
Default: 9600 baud, 8N1 (8 data bits, no parity, 1 stop bit). Slave address: 0x01.
Industrial Automation Engineers
Working with protocol specs and configuration guides
Example Query
“What's the LoRaWAN join accept delay?”
ManualFlow Response
JOIN_ACCEPT_DELAY1 = 5 seconds, JOIN_ACCEPT_DELAY2 = 6 seconds after join-request TX.
