STM32F429/439. The STM32F429/439 lines offer the performance of the Cortex-M4 core (with floating point unit) running at 180 MHz while reaching lower static power consumption (Stop mode) versus STM32F405/415/407/F417. Performance: At 180 MHz, the STM32F429/439 deliver 225 DMIPS/608 CoreMark performance executing from Flash memory, with 0-wait. sht-标准modbus协定-湿度[最新]. Communications Ports2 RS-485 NET1, NET2 supporting:BACnet MS/TP up to 76800 bpsOptional Modbus up to 115200 bps8. The Modbus RTU protocol is more compact and uses binary communication. In this format, a message is always followed by a cyclic redundancy check checksum, which is used to detect transmission problems. The second variant is the Modbus ASCII protocol. This version is more verbose, and it uses ASCII characters that can be read by human operators.

MODBUS RTU establishes a serial master/slave communication via RS-232 or RS-485. In order to address the MODBUS RTU, first the serial communication parameters must be known and/or defined. These parameters include baud rate, parity and stop bits.
