2022Q3-CH552G-DIY

Overview

1. USB-A free serial port chip download
(need to short-circuit the 2P pin header of V33 and +5V 2P pin header)
PS: After downloading, you need to remove the short-circuit pin header of V33 to operate normally
(otherwise, it will automatically enter the download The mode will not run the code)
2. The USB-B interface is relatively strong (personally prefer it)
3. Except for the MCU, they are all plug-ins (the handicapped party is ecstatic)
4. The BOMCOST is extremely low (the student party is ecstatic)
5. There are 4 rows of pin headers , you can directly customize it
and use it as a breadboard or badusb.

Would you choose c2000's 2837xS/D for project development?
TI's 2837xx has been out for more than a year. Yesterday, I attended a TI exchange meeting where this new product was introduced. There are many optimizations, not just the difference in main frequenc
FPGA is used as the master to collect data, and MSP430 is used to display
I use MSP430F5438A to drive the color screen, and then FPGA collects AD or measures frequency. How can I send the data obtained in this way to the color screen controlled by MSP430F5438A for display?
