Hello,

I'm using the UART API as follows:

while(0 == UART_1_GetRxBufferSize());
Receive = UART_1_GetByte();
if((Receive & 0xFF00) == 0) {
	*data = (char) (Receive & 0x00FF);
}

The UART component datasheet states for UART_GetByte():

Return Value: uint16: MSB contains status and LSB contains UART RX data. If the MSB is nonzero, an error has occurred.

I'm getting 0x20 for the MSB. Digging through the API sourcecode, it seems that bit 5 indicates that the FIFO is not empty (UART_1_RX_STS_FIFO_NOTEMPTY).
I wonder if I'm handling the return value wrong or if the API simply has a bug - I think it should mask out the FIFO not empty flag since if the FIFO still has data this is not an error 😄

Anyone can confirm this?

Regards

Hello, quick question, it looks like Modus Tool Kit doesn't support PSOC5 devices, is this a permanent thing, is the PSOC5 being discontinued, or are they keeping the PSOC Creator around for the PSOC5 devices?

Thank you

Joe

Create a Square Wave (0 – 5 V) where frequency lies in the range of 150 Hz to 15 kHz with
varying duty (1 % resolution).  (USE PWM BLOCK)

@sk7211  It would be beneficial & time-saving If you can directly provide me with all your Files of yours ..HEX. GUI(EXE) . Most importantly zadig driver installer can detect.
