Dear Sirs and Madams,

 

We are considering HSSP for PSoC4.

Therefore, I refer to the information of KBA93541.

 

KBA93541

We have downloaded and referenced the "4 dollar programmer_001-93541.zip" attached to KBA.

So I have a question about this project.

I know it's probably a clerical error, but please check it.

I think it is correct that line 120 uses the ”UART_Rx_ClearRxBuffer()” API of the UART_Rx component,

However "UART_Rx_ClearRxBuffer()" on line 87 in the project's main.c, shouldn't this be "SCB_SpiUartClearRxBuffer()"?

 

Regards,

Hi @MiNe_85951,

The project was created with the old component of version 1.10
that is why the old API UART_Rx_ClearRxBuffer() is used.
 

Warm Regards,

Gautami-san,

 

Thank you for your reply.

Have you confirmed for the project for "4 dollar programmer_001-93541.zip"?

 

In this project, UART(SCB) and UART(UDB)  are placed on the schematic.

In main.c, these two components are used properly.

MaMi_1205306_1-1652447106080.png

The description of UART (SCB) corresponds to the following:

MaMi_1205306_2-1652447172593.png

Similarly, The description of UART (UDB) corresponds to the following:

MaMi_1205306_3-1652447235937.png

My question points out that it is a mistake to describe the UDB API in the SCB description.

 

I have read your answer and confirmed the v1.10 data sheet.

component - PSoC4 SCB v1.10 Datasheet URL

https://www.infineon.com/dgdl/Infineon-Component_PSoC_4_SCB_V1.10-Software%20Module%20Datasheets-v04...

 

Even in v1.10, UART_Rx_ClearRxBuffer () is not an API for SCB UART.

 

I think you don't need the buffer clear API as it will be overwritten on the next receive.

However, don't you think it makes no sense to write the API of UDB(UART_Rx_ClearRxBuffer ()) on line 87?

I think it is correct to write the API of SCB(SCB_SpiUartClearRxBuffer()).

 

Would you please check again?
