Hi
My code snippet is below. My goal is to transmit on UART using DMA. I have the following problems
Option 1:
When I use the HAL_DMA_TMODE_BLOCK mode with Manual trigger to begin the TX (HAL_DMA_TRIG_NONE) and then switch over to HAL_DMA_TRIG_UTX0 trigger, the problem I am facing is that the transfer continues on an on and there is no way of stopping it ( I know I am in an infinite loop. The code does not TX without it). More over the data that is sent is also semi junk. Part of it is valid and some other parts are invalid.
Data I planned to send -> "0123456789ABCDEFGHIJ";
Data out -> JBJ7J3JJJJFJBJ7J3JJJJFJCJ8J4J0JJGJDJ9J5J1JJHJDJ9J5J1JJHJEJAJ6J2JJIJEJBJ7J3JJJJFJBJ7J3JJJJFJCJ8J4J0JJGJDJ9J5J1JJHJDJ9J5J1JJHJEJAJ6J2JJIJEJBJ7J3JJJJFJBJ7J3JJJJFJCJ8J4J0JJGJDJ9J5J1JJHJDJ9J5J1JJHJEJAJ6J2JJIJEJBJ7
Option 2:
When I use the HAL_DMA_TMODE_BLOCK mode with Manual trigger to begin the TX (HAL_DMA_TRIG_NONE) , the problem I am facing is that the transfer continues on an on and there is no way of stopping it ( I know I am in an infinite loop. The code does not TX without it). More over the data that is sent is also semi junk. Part of it is valid and some other parts are invalid.
Data I planned to send -> "0123456789ABCDEFGHIJ";
Data out -> 06BHJJJJJ4AFJJJJJ28DJJJJJ06BHJJJJJ4AFJJJJJ28DJJJJJ06BHJJJJJ4AFJJJJJ28DJJJJJ06BHJJJJJ4AFJJJJJ28DJJJJJ06BHJJJJJ4AFJJJJJ28DJJJJJ06BHJJJJJ4AFJJJJJ28
Option 3:
When I use the HAL_DMA_TMODE_BLOCK mode with Manual trigger to begin the TX (HAL_DMA_TRIG_NONE) and then switch over to HAL_DMA_TRIG_UTX0 trigger, the problem I am facing is that the transfer continues on an on and there is no way of stopping it ( I know I am in an infinite loop. The code does not TX without it). More over the data that is sent is also semi junk. Part of it is valid and some other parts are invalid.
Data I planned to send -> "0123456789ABCDEFGHIJ";
Data out ->DEFGHIJ0123456789ABCDEFGHIJ0123456789ABCDEFGHIJ0123456789ABCDEFGHIJ0123456789ABCDEFGHIJ0123456789ABCDEFGHIJ0123456789ABCDEFGHIJ0123456789ABCDEFGHIJ0123456789ABC
The problem I face in option 3 is that the transfer never stops !!!!! Even if the controller stops at a debug breakpoint. The dilemma is that the TX does not begin without the infinite loop and does not end may be because I am in an infinite loop.
