Smartcard communication gets disturbed by communication on another UART, what can be the reason?
UART2 is used for as smart card communication. (sign data)UART1 is used for communication from outsideIt looks like the communication to the smart card can get disturbed by communication on UART1result invalid signature. The interrupt priority of UA...
Resolved! Enabling and disabling CCR interrupts on a running timer.
Hello all. I am trying to set up a continuously running timer to use to set of interrupts at specific counts of the timer. So the user of this thing would say "setAlarm(n)" and at timer=n an interrupt goes off. But I also want interrupts for the ccr...

Problem with UART Interrupts (ICSR->ISRPENDING always 1) after jumping to booloader from main application
I have built an main application (using HAL) and a bootloader project (using LL).When debugging seperately, the UART reception using interrupts works well in both projects.But after I jump to bootloader from main application, immediately after re-ini...
How to recover UART RX with DMA after Frame or OverRun error.
Because of nature of my application sometimes I need to disconnect the cable for UART. In tthat case frame error is detected (sometimes noise or overrun). I would like that after reconnection of the cable UART communication comes back. After reconnec...
