| Summary | 0000644: Prepare CAN and SPI driver to work on HW revision 1.20 simultaniously | ||||
| Description | Due to a HW issue, CAN and external SPI interface can not be used simultainously on HW revision < 1.20. The native chip select signal is available on both interfaces. In HW revision 1.20 there are two different pins designed for chip select usage. | ||||

|
There are changes required in CAN and SPI driver to enable simultanious operation. Therefore this feature has been rescheduled. SPI and CAN driver will also work on HW revision 1.20: * CAN driver still uses native CS pin * SPI dirver queries CEDDK for CS pin and DIO table in CEDDK has already been prepared for rev 1.20. |
|
|
DirectInterface option added (like on PicoCOM2). CAN driver may use SPI driver to access CAN chip if SPI driver should be used simultanioulsy. |
