I prepared how to use sprintf for PSoC4000S.
It can be sent with sprintf using the Tx UART of PSoC 4000S on the terminal software(for example Tera Term).
Unlike printf, there is no need to increase heap memory.
You can also change the value to diplay using EZI2C from the "Bridge Control Panel".
I prepared the script file "Sprint.iic." for "Bridge Control Panel".
The "Bridge Control Panel" and terminal software can be operated at the same time.
You can make changes dynamically with the "Bridge Control Panel" while operating the terminal software.
