Problems solved by technology
However, when the above method is implemented, since the parameter setting of the vacancy and the adjustment pin is usually single or limited, it is impossible to repeatedly read and write the integrated circuit, and the parameters to be adjusted are usually in the integrated circuit. It is only available after soldering to the circuit board, so repeated removal of the IC from the circuit board can also cause damage to the circuit
It can be seen that in the prior art, the parameter adjustment of the integrated circuit is relatively difficult to operate due to the uniqueness of its information reading, and the number of adjustments is limited.
Increases the cost of using integrated circuits and reduces the overall reliability of the circuit

The invention discloses an adjusting circuit and a circuit adjusting method. The circuit comprises an EEPROM (electrically erasable programmable read-only memory) and a state machine; an additional storage unit is arranged in the EEPROM, adjusting parameters corresponding to different state values of a to-be-adjusted circuit and the state machine are preliminarily stored in a storage address of the storage unit, the state machine is connected with a reading-writing port of the EEPROM, the corresponding storage address is read according to the current state value of the to-be-adjusted circuit and the state machine, and the adjusting parameter is read from the storage address; and the to-be-adjusted circuit and the state machine are adjusted according to the adjusting parameter. By adopting the adjusting circuit and the circuit adjusting method, the problem that the existing circuit parameter is complicated to adjust can be solved. The circuit unit is adjusted, the flexibility for adjusting the circuit can be improved, the universality of the circuit is improved, and the maintenance and application cost of the circuit can be reduced.
Description
technical field [0001] The invention relates to the field of automatic control and electronic application, in particular to a circuit adjustment method and an adjustment circuit. Background technique [0002] With the improvement of modern integrated circuit production technology, the production cycle of integrated circuits is shortened day by day, and the circuit scale is increased day by day. In the actual application process, the driving or control integrated circuit needs to be adjusted according to the actual application situation, but usually, after the integrated circuit is taped out, the internal parameters have been set. If adjustment or modification requires special equipment and needs Long operating cycle. In view of the above-mentioned problems, in the prior art, the regulation of the circuit is realized by presetting the vacant or existing regulation pins of the integrated circuit. However, when the above method is implemented, since the parameter setting of t...
