PSoC 4 MCU

Contributor II

 Hi,

   

If all others fails => read the Datasheet carefully. 

   

The SW_Tx_UART supports PSoC 3, PSoC 4 and PSoC 5LP.

   

Small notice on the page 7 of the SW_Tx_UART Version 1.10 Datasheet 

   

.... is  IMPORTANT ....

   

"Software Transmit UART component requires to have Instruction Cache to be enabled for PSoC 3 and PSoC 5LP. This could be done in PSoC Creator project Design-Wide Resources editor on the System tab. By default, this option is enabled".

   

If the Instruction Cache is disabled the SW_Tx_UART works but erroneously. 

   

Behaviour - using 115200 Baudrate and 24MHz BusClock same number of characters transmitted, but all characters NONREPRODUCIBLE - RANDOMLY substituted.

   

NO WARNING in PSoC Creator 3.0 compilation/linking, NO USABLE INFORMATION from the logic analyzer.

   

 

   

May be this helps.

   

 

   

Regards, 

   

Viktor

Maybe just posting this once in Creator forum more effective ?

   

 

   

Just a thought.
