Hi all!
I've having an issue with my XMC4500 relex kit and usic channel. Here's my code:
As you can see it's almost a copy from the I2C example, but still doesn't give me any output ( I configured the end of transmit callback to be function tx_callback_0 and the pins to be SCl:0.8 and SDA:1.5)
and in the debugger when I lock at USIC0_C0 address I find all ones

Thanks in advance!
I've having an issue with my XMC4500 relex kit and usic channel. Here's my code:
Code:
volatile uint8_t tx_completion_0 = 0;
/* Transmit callback handling */
void tx_callback_0(void)
{
tx_completion_0 = 1;
}
int main(void)
{
DAVE_STATUS_t status;
uint8_t tr1[7] = { OLED_CONTROL_BYTE_CMD_STREAM, OLED_CMD_SET_COLUMN_RANGE, 0x00, 0x7F, OLED_CMD_SET_PAGE_RANGE,0x00, 0x07 };
status = DAVE_Init(); /* Initialization of DAVE APPs */
XMC_DEBUG("here at least?...")
if(status == DAVE_STATUS_FAILURE)
{
/* Placeholder for error handler code. The while loop below can be replaced with an user error handler. */
XMC_DEBUG("DAVE APPs initialization failed\n");
while(1U)
{
}
}
/* Placeholder for user application code. The while loop below can be replaced with user application code. */
while(1U)
{
I2C_MASTER_Transmit(&I2C_MASTER_0, true, OLED_I2C_ADDRESS, tr1, 7, true );
while(!tx_completion_0);
tx_completion_0 = 0;
for(uint16_t i=0;i<1024;i++){
I2C_MASTER_SendStart(&I2C_MASTER_0, OLED_I2C_ADDRESS, XMC_I2C_CH_CMD_WRITE);
I2C_MASTER_TransmitByte(&I2C_MASTER_0, OLED_CONTROL_BYTE_DATA_STREAM);
while(!tx_completion_0);
tx_completion_0 = 0;
for (uint8_t x=0; x<16; x++) {
I2C_MASTER_TransmitByte(&I2C_MASTER_0, 0x81);
while(!tx_completion_0);
tx_completion_0 = 0;
i++;
}
I2C_MASTER_SendStop(&I2C_MASTER_0);
}
}
}and in the debugger when I lock at USIC0_C0 address I find all ones
