I need some clarification on using the Uart device in DMA modehow should i handle the overrun condition (ORE bit set in SR register) ?The read sequence SR and DR register reset the ORE bitIn DMA mode how I can do this ? I must enable the EIE bit in C...

Ok for the code I am sorry, my question could have been more general without adding my codeYour reply confuse me a bit.ORE can't generate itself an interrupt but is associtate to receive flag RXNE that generate Uart interrupt. Or rather the Uart inte...
Thanks for repliesThe overrun isn't a real problem but I ask how to handle it if arise I am agree TDK normally the ORE flag never can be set in DMA transfer but we want prevent....Library is an own older Library write around SPL (I think this is the ...

uB_I2C_GPIO_config(id, i2c) ;
I2C_SoftwareResetCmd(I2c[id].base, ENABLE );
I2C_SoftwareResetCmd(I2c[id].base, DISABLE);
