Add support of SPI API for STM32H5 family (#324)
* fix PWM pin map in context of Timer change * Note about DAC on Nucleo-H503RB * Add ADC and DAC for STM32H5 * Copyright fix * Add I2C for STM32H5 * fix I2C related code * ADC/DAC fix * Enable I2C API * Copyright fix * Add SPI for STM32H5 * Modification of stm spi API for h5 family * fix I2C device * fix I2C ASYNCH macro * fix revert back the stop variable position * Fix clock for SPI * fix some details * Rename startup_stm32h563xx.s to startup_stm32h563xx.S * Rename startup_stm32h503xx.s to startup_stm32h503xx.S --------- Co-authored-by: Jan Kamidra <[email protected]>
