Marian Buschsieweke 051a1f1e32 boards/common/blxxxpill: rework periph configuration ... The peripheral configuration has been completely reworked to resolve pin conflicts while provided as much of the peripherals as possible. The changes include: - Move `I2C_DEV(0)` from PB6/PB7 to PB8/PB9 to solve pin conflict with `QDEC_DEV(2)`. - Use pins PB0, PB1, PB4, and PB5 for PWM instead PA8, PA9, PA10, and PA11 - PA9 and PA10 is in pin conflict with `UART_DEV(0)` which is used for stdio with `stdio_uart`, PA8 was in conflict with `QDEC_DEV(0)`, PA11 was in conflict with USB D- - Use PB6, PB7 as `QDEC_DEV(0)` (previously `QDEC_DEV(2)`), as this is the only completely conflict free setting - Use PB4/PB5 instead of PA6/PA7 for QDEC_DEV(1) - This fixes a pin conflict with `SPI_DEV(0)` MISO (and `ADC_LINE(4)`) - Only provide QDEC at PB4/PB5 when PWM is not used to avoid conflict - Only provide QDEC at PA8/PA9 when UART is not used to avoid conflict - Use SPI2 (PB15, PB14, PB13, PB12) as `SPI_DEV(0)` instead of SPI1, use SPI1 (PA7, PA6, PA5, PA4) as `SPI_DEV(1)` - Only provide `SPI_DEV(1)` if the ADC is not in used to resolve a pin conflict - Move PB0 and PB1 at the end of the ADC lines (previously `ADC_LINE(6)` and `ADC_LINE(7)`, now `ADC_LINE(8)` and `ADC_LINE(9)`) - Only provide them when PWM is not in use (to resolve pin conflict with PWM) - Also do not provide them for the Blackpill boards, which are missing pins PB0 and PB1 on the headers To make life of users easier, a Pinout diagram with the new configuration was added.		2022-10-27 14:28:07 +02:00
