Embodiment Construction
[0049]The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.
[0050] see figure 1 As shown in FIG. 2 , it is a flow chart of an embodiment of the error correction method for firmware upgrade of a touch device provided by the present invention.
[0051] The firmware upgrade error correction method of the touch device according to the embodiment of the present invention includes:
[0052] Step S101, after the firmware upgrade of the touch device is completed, reset and power on the touch device;
[0053] Step S102, judging whe...

The invention relates to the technical field of touch, and discloses a firmware upgrading error correction method of touch equipment and a control device. The method comprises the steps of resetting and powering on the touch equipment after firmware upgrading is finished, modifying a firmware upgrading mark state into a to-be-detected state, and modifying the firmware upgrading mark state into a normal starting state when firmware detection is normal, therefore, the firmware can be normally used, and the touch equipment can be normally used; when firmware detection is abnormal, returning to the reset power-on step, and since the firmware upgrading mark state is still the to-be-detected state, and when it can be detected that the firmware upgrading mark state does not accord with the normalstarting state after fault reset, re-upgrading the touch equipment, so that the touch equipment can be normally used. The problem that the touch equipment cannot be used due to firmware errors in theprior art is avoided.
Description
technical field [0001] The invention relates to the field of touch technology, in particular to a firmware upgrade error correction method and control device for a touch device. Background technique [0002] Existing touch devices (such as infrared touch screen products) will stay in the boot layer for a few seconds during the startup process, and then jump to the algorithm driver layer, which will increase the time from power-on to touch on the touch screen. When there is a problem with the upgraded firmware, such as a crash, etc., it needs to be powered on again to upgrade. During the restart process, it will be upgraded when it stays at boot, because every time it is powered on, it will stay at the boot layer, which will cause the product to be powered on. The touch time is prolonged, which affects the user experience. When the upgraded firmware crashes, and the system does not restart automatically, resulting in the product being unusable, it is necessary to power off t...
