RTOS/TDA2P-ACD: Accepting Multiple Input Characters from User over UART Console

Abhay Sorte

Part Number: TDA2P-ACD

Tool/software: TI-RTOS

Dear All,

I am working on TDA2Px-EVM with Processor SDK 03.05. I have a requirement wherein my application requires a 2-digit number as an input from user over UART console. I found API's "Chains_readChar()" & "uartRead()" in Vision SDK but these API's accept only a single character from UART console. Is there any other API available in Vision SDK that I can use for taking multiple characters as input from console (for example: '77' or '34'). If no, then how can these be achieved ? Do I need to create my own API for this ?

Please suggest.

Thanks,

Abhay

Hi Abhay,

One way could be using ASCII characters. Will it work for you?

Hi Abhay,

For example ASCII value of "M" is 77.
Please search internet for ASCII table.

Hi Abhay,

You can also choose to write a wrapper API on top of API to receive two characters and use it.

May be you could implement a readstring API and convert into number, the way it is done in apps/src/rtos/radar/src/usecases/cascade_radar_object_detect/chains_cascadeRadarOd.c usecase.
