Retrives the number of bytes in the SWO buffer. num_bytes ( int) – the number of bytes to flush.If num_bytes is not present, flushes all data currently in the SWO port_mask ( int) – port mask specifying which stimulus ports to enableĪfter this method is called, the flushed part of the SWO buffer is.swo_speed ( int) – the frequency in Hz used by the target to communicate.cpu_speed ( int) – the target CPU frequency in Hz.If SWO is already enabled, it will first stop SWO before enabling it Parameters:Ĭonfigures the output protocol, the SWO output speed, and enables any Writes one byte over SWD (Serial Wire Debug). Writes four bytes over SWD (Serial Wire Debug). Writes two bytes over SWD (Serial Wire Debug). The bit position of the response in the input buffer. nbits ( int) – the number of bits needed to represent the output and.value ( int) – the value to write to the output buffer.output ( int) – the output buffer offset to write to.Writes bytes over SWD (Serial Wire Debug). pad ( bool) – True if should pad the data to full byte size.Parameters:Ĭauses a flush to write all data remaining in output buffers to SWD

Gets a unit of 8 bits from the input buffer.

Gets a unit of 32 bits from the input buffer. offset ( int) – the offset (in bits) from which to start reading.Gets a unit of 16 bits from the input buffer. The shared library is loaded and used to call the SDK methods. This is a wrapper around the J-Link C SDK to provide a Python interface JLink ( lib=None, log=None, detailed_log=None, error=None, warn=None, unsecure_hook=None, serial_no=None, ip_addr=None, open_tunnel=False ) Serial Wire Methods ¶ class pylink.jlink.
