Stefan Kerkmann	1b6540a61c	Update systick reload value ... The systick timer is driven by the AHB bus divided by 4, set the correct reload value to generate a timer irq every ms.	2021-08-09 21:37:06 +02:00

Stefan Kerkmann	60d03110f7	Correctly initialize and handle the system tick ... Forgot to reload the systick timer in the irq handler	2021-08-07 11:33:36 +02:00
Stefan Kerkmann	1d2a57a9e1	Remove unsuitable clock configurations from init code ... Only 48MHz, 72MHz, 96MHz and 120 MHz system clocks derived from an external crystal are suitable for the usb peripheral, as the internal oscillator is not stable enough. Also the usb-prescaler only supports division by 1 (48MHZ), 1.5(72MHz), 2(96MHz) and 2.5(120Mhz). 120Mhz is also out of spec and not added here.	2021-08-07 11:33:36 +02:00
Stefan Kerkmann	733a362436	Use nuclei-sdk functions for init code ... Instead of using the HAL functions we can just use the defines from the board support for the longan nano that comes with the nuclei-sdk. Also we move some includes and defines to the header file.	2021-08-07 11:32:06 +02:00
