Q:How to choose RESE?
A:The user can operate according to the instructions of the RESE corresponding to different sizes of electronic paper in the DEMO board instruction manual, only 0.47 and 3 ohms.
Q:Is there a prompt after the program is downloaded?
A:An LED indicator is onboard and will be illuminated when the program is downloaded.
Q:Does the SPI serial port choose three or four wires?
A:The default four-wire SPI, if the user wants to use three wires, you need to connect the BS pin to a high level.
Q:Does it support parallel communication?
A:The onboard CH340G is a USB to parallel chip. Users can directly connect the PC to the DEMO board with a USB cable, and then they can perform their own serial port operation.
Q:Does it support current measurement?
A:The latest boards support users in measuring on-board power consumption and e-paper power consumption.
Q:Does it support SPI interface download?
A:The user can download the SPI interface through the corresponding Boot interface of the onboard short-circuit, and download the software to operate with the FLYMCU. The download mode is similar to that of the C51.
Q:Does it support the development of other products?
A:All of the pins of the MCU have been taken out by our DEMO motherboard. Users can connect to other external devices through this DEMO board to design and develop other products.
Q:Does it support multiple sets of e-paper drive circuits to drive e-paper at the same time?
A:Yes, the DEMO motherboard can drive multiple sets of electronic paper drive boards, which have been reserved.
