> I looked at the F103 and the SPEED setting is coupled with making the pin an output. It is 0 for input. > > ``` > 00: Input mode (reset state) > 01: Output mode, max speed 10 MHz. > 10: Output mode, max speed 2 MHz. > 11: Output mode, max speed 50 MHz. > ``` > > So we would have to replace all SPEED_XXX with the lowest speed. Then provide a STM32_ADJUST_SPEED(pinset, speed) macro. to allow changing it at the board level. > #define GPIO_USART1_RX STM32F1_ADJUST_MODE(GPIO_USART1_RX_0, GPIO_MODE_10MHz)` @slorquet, @raiden00pl does this seem like a reasonable approach? -- This is an automated message from the Apache Git Service.
