915 Generation STM32F103C8T6 USB Interface 10 Channel 12Bit AD Sampling Data Acquisition STM32 UART Communication for Module

Install the USB to serial port chip CH340 driver plug the module into the computer IN0-IN9 is connected to the sampling voltage positive GND is connected to the sampling voltage negative ie common processing open the serial debugging assistant select the port and rate 115200 you can the AD sampling the sampling is refreshed in 500ms the customer can this time on the basis of code
If you to use the external MCU to obtain the sampling data directly you can connect the 33V TX and GND of the MCU to the 33V TX and GND of the module Of course it is ok to supply the module with 5V The protocol for data transfer can be found by looking at code If the customer wants to code re- the
The is as follows Insert the module into the USB port of the computer insert the jumper cap on the module to the 3V3 end note that it should be plugged back to GND after the programming is completed open the programming software FlyMcu open the hex file set the port number and wave For the relevant parameters such as the rate click " Programming" then use the tweezers to clamp the two ends of the capacitor C9 equivalent to reset
The sampling voltage input terminals IN0-IN9 can be connected or only partially connected When a certain channel has no sampling voltage input the output of the channel is a multicolor value and the unused port can also be modified by itself as a normal IO port
The voltage used should not 33V otherwise there is a possibility of damage to the chip

Product Feature
The 10-channel module uses the internal 10-channel resources of the STM32F103 series as the sampling core and transfers the acquired sampling data to the internal memory through the STM32to reduce the CPU load and enhance the stability of the AD sampling Accuracy while the onboard USB to serial port chip can transfer data to the computer
