For example, there are five buffers, the preset number is two, when the number of the filled buffers reaches two (that is, the preset number is reached), the burst transmission is started, and at this time, the transmission is started while buffering. The preset number is smaller than the set number of the pulse areas, so that the storage space occupied by pulse transmission can be reduced, and the efficiency of pulse transmission is improved.

If the sent data volume is equal to the buffer depth of the buffer zone corresponding to the sent pulse, which indicates that the pulse signals in the buffer zone corresponding to the sent pulse are all sent, then the pulse signals of the next buffer zone are sent; and if the sent data volume is smaller than the buffer depth of the buffer corresponding to the sent pulse, which indicates that the pulse signals in the buffer corresponding to the sent pulse are not completely sent, continuing to send the pulse signals to the buffer until the pulse signals of the buffer are completely sent.

In some embodiments of the present application, as shown in fig. 8, the pulse transmission method further includes, but is not limited to, the following steps:

Specifically, when the pulse is sent, the sorting information of the buffer area currently carrying out the pulse sending is acquired, and the next buffer area is defined according to the sorting information. If the sequencing information of the currently sent buffer area is the last buffer area, defining the first buffer area as the next buffer area; and if the sequencing information of the currently sent buffer is not the last buffer, defining the buffer behind the current buffer as the next buffer.

And acquiring the storage state of the next buffer area, and acquiring the setting state of the completion flag according to the storage state. And when the storage state of the next buffer area is not empty, the next buffer area is subjected to pulse transmission until the storage state of the next buffer area is empty. And when the storage state of the next buffer area is empty, acquiring the setting state of the completion flag. If the completion flag is set, indicating that all the pulse signals are sent completely, ending the pulse sending and outputting a signal for finishing the instruction execution; if the completion flag is not set, which indicates that the sending speed is faster than the buffering speed, the buffer supplementing operation is executed, namely the sending is suspended, and the pulse sending is continued after the pulse signal of one buffer area is supplemented. The condition that the transmission is faster than the buffering can be avoided by adjusting the buffering depth of the buffer area and the number of the pulse signals buffered in the period.

The pulse transmission method according to an embodiment of the present application is described in detail below in a specific embodiment with reference to fig. 1 to 9. It is to be understood that the following description is illustrative only and is not intended to be in any way limiting.

For example, five buffer areas are set according to a preset requirement, the cache depth of the buffer areas is 100, two buffer areas are filled each time, and the preset number is one. The pulses are divided from 1Hz into 10000 steps and accelerated to 9999Hz pulse by pulse, the phase comprises 9999 groups of parameter values with the frequency increment number of 1, then the frequency is unchanged, 100000 pulses are continuously sent, and finally the pulse by pulse is decelerated to stop.

And meanwhile, continuously filling the second buffer area, performing other work backwards in a scanning period after the second buffer area is filled, and filling the third buffer area and the fourth buffer area when the next cyclic scanning reaches the position and if the storage states of the first two buffer areas are not empty. And when the fifth buffer area is filled, filling the first buffer area as the next buffer area until the data volume to be filled is filled, and setting the completion flag bit of the corresponding buffer area when the filling is finished.

For example, after the transmission of 100 groups of pulse signals included in the first buffer is completed, the transmission of the pulse signals of the second buffer is started, and the storage state of the first buffer is changed to be empty. Before the next buffer area is subjected to pulse transmission, whether the completion flag of the buffer area is set or not is checked, if the completion flag of the buffer area is set, the pulse transmission is finished, and if the completion flag of the buffer area is not set, the next buffer area is subjected to pulse transmission. And when all the pulse signals are sent completely and the completion flag bit is set after being checked, ending the pulse sending.

The following describes the embodiments of the present application with four specific application examples.

Application example 1: and based on the pulse inching instruction of the MCU timer peripheral.

When the inching pulse sends a request enable instruction, the pulse frequency is gradually accelerated to a set value from 0 and then is sent to the incapability all the time, and the pulse frequency is gradually decelerated to stop from the current speed when the incapability is realized.

Starting the process of accelerating to the target frequency, wherein the process is the same as the specific embodiment, when the target frequency is reached by operation, a group of values with the frequency as the target frequency and the quantity as 1 are filled, and then the deceleration stage is continuously calculated backwards; when the sending operation reaches the target frequency, the buffer data used by the sending-all-time mark control given in the initialization is not switched back after the group is sent, but the group data is repeatedly used until the sending-all-time mark is reset after the failure is detected, and the data is continuously switched back to enter the deceleration stop stage.

Application example 2: multi-segment pulse instruction based on the above embodiment

The multi-segment pulse transmission requires that several segments of pulses with different acceleration and deceleration processes, respective target frequencies and total numbers, can be continuously transmitted.

On the basis of the above specific embodiment, the setting timing of the completion flag is modified. After the single-segment pulse data is cached, switching to the next segment to continue caching to the current buffer area, in the process, there may be a linking calculation process between the segments, given by the parameter during initialization, setting a calculation completion flag when all data of the last segment is calculated, and the sending process is completely consistent with the above-mentioned specific embodiment.

Application example 3: external signal control mechanical zero returning instruction based on application example 1

In the automatic control, a zero-returning operation is often required to reset or calibrate the position, and the zero point is generally marked by an external signal provided by a sensor, wherein the zero point triggering means that the machine enters a zero-returning area and needs to be decelerated from a high speed to a low speed, and then the zero-returning operation needs to be stopped when the signal disappears.

In this example, there are two frequencies, the faster return to zero frequency is called the return speed, and the slower frequency after the zero signal is detected is called the creep speed.

When a zero return instruction is started, if the zero point signal is in an un-triggered state, the acceleration is firstly accelerated to a return speed, and the acceleration process is the same as that of the specific embodiment; after the regression speed corresponding data is sent all the time, the filled data in the buffer area is continuously calculated to be the data in the process of decelerating from the regression speed to the crawling speed, then a group of values with the crawling speed corresponding to the frequency number being 1 is refilled, and the data is not filled any more. Moving to the zero point at the return speed all the time, and when the zero point signal is triggered, resetting the sending mark all the time and stopping sending; and the buffer area is switched to a deceleration stage backwards, the sending-all-time mark is set again until the buffer area is started to be switched to the crawling frequency, the buffer area slowly moves at the crawling speed again, and the sending is stopped immediately when the return-to-zero signal disappears. If the zero point signal is already in a trigger state when the zero return instruction is started, the operation and the transmission are directly accelerated from 0 to the crawling speed and then are transmitted all the time, and the pulse transmission is stopped as long as the zero point signal disappears in the whole process.

Application example 4: multi-axis linkage pulse instruction based on MCU timer peripheral

The multi-axis linkage pulse transmission requires that a plurality of linkage shafts are started and stopped as simultaneously as possible, and the number of pulses transmitted by each shaft keeps a certain mathematical relationship, so that the multi-axis linkage pulse transmission system is commonly used in the fields of plane and 3D position control, industrial robots and the like.

And setting a mathematical relation among the pulse numbers sent by each axis according to specific requirements, and filling the mathematical relation into a buffer area when pulse data are cached.

In a multi-axis linkage application, a single set of data in the buffer will include parameters such as the number of frequencies of multiple axes in the transmission interval, and the filling process is consistent with the above embodiments.

The pulse sending process is composed of reading and switching of buffer area data of each axis, and is different from a single axis in that register configuration of all axes needs to be filled when starting sending and then started, only data switching is carried out when the number reaches the data switching time in interruption of each axis, and after the last axis completes sending of the group data and data switching, all axes are opened to send the next group of pulses.
