Branch Targeting Suggestion

You've targeted the master branch with this PR. Please consider if a version branch might be more appropriate:

  • maintenance-9.x - If your change is backward-compatible and won't create compatibility issues between INAV firmware and Configurator 9.x versions. This will allow your PR to be included in the next 9.x release.

  • maintenance-10.x - If your change introduces compatibility requirements between firmware and configurator that would break 9.x compatibility. This is for PRs which will be included in INAV 10.x

If master is the correct target for this change, no action is needed.

This is an automated suggestion to help route contributions to the appropriate branch.

Suggestion: Comment out the conflicting timer definition for TIM5 on pin PA2 to resolve a resource conflict with UART2_TX_PIN. [possible issue, importance: 9]

Suggested change
DEF_TIM(TIM5, CH3, PA2, TIM_USE_ANY, 0, 0), //TX2 softserial1_Tx

Suggestion: Reassign SOFTSERIAL_1_RX_PIN from PA2 to another pin like PA3 to avoid conflicting with SOFTSERIAL_1_TX_PIN on the same pin. [possible issue, importance: 9]

Suggested change
#define SOFTSERIAL_1_TX_PIN PA2
#define SOFTSERIAL_1_RX_PIN PA2
#define SOFTSERIAL_1_TX_PIN PA2
