The EEPROM facility is being faked with RAM based storage. The desired machine parameters should be compiled into the firmware.\n* The CDC USB serial device implemented on the board is not as reliable as it needs to be. Pending bug fixes the option of a normal serial port using the USART hardware has been implemented. This can be enabled in the makefile by setting \"USB_SERIAL = 0\".\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fdeadsy%2Fgrbl_stm32f4","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fdeadsy%2Fgrbl_stm32f4","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fdeadsy%2Fgrbl_stm32f4/lists"}
