From the first time build touch the working load that accuses to use a program to reach debug difficulty of comparative both different. Use touch accuse IC and touch in dominating MCU application program, soft, hardware constitutes sketch map, if pursue,1 is shown.

 

 

Graph 1 use touch in dominating IC and MCU application program, soft, hardware forms a plan

 

Use in striking the applied plan that dominates IC, advocate accuse MCU and touch dominate the data trade between IC, it is to pass serial interface normally (for example, i2C, SPI) comes true. Accordingly, the user needs to develop corresponding communication program, execute the several trade that occupy. No matter be to use advocate the hardware that controls MCU is serial interface, still use software simulation serial agreement realizes data to transmit, raised the negative charge that software develops. Debugging initial stage especially, if advocate accuse MCU to cannot detect correctly touch dominate an action, needing judgement breakdown source is to touch accuse IC unusual, or communication order is unusual, or advocate accuse MCU side to detect the mistake of the program. Accordingly, increased the difficulty that software debugs greatly. And the applied plan of use Rx130, the user needs to will develop what tool Workbench generates to touch only control a process, compositive in the software project to applied plan. Rx130 is called simply touch control API interface function, read the sign in taking MCU RAM, can finish touch accuse to have / the judgement that not have. In addition, workbench generates touch control a process, it is the target that is based on an user normally circuit board, finished preliminary Tuning to generate. Accordingly, its validity is beyond question. Although overall in debugging a process, malfunction, need to check only, revise advocate control a process, decreased to debug content thereby, benefit at debugging the fixed position of source of the breakdown in the process and trouble removal.

 

 

Graph 2 optimize touch the working environment that controls IC

 

 

From touch accuse parameter (for example, sensitivity) the point of view that changes subtly, of comparative both different. Touch accuse IC normally inside buy default parameter, if advocate accuse MCU detect program and communication procedure are correct, so MCU and touch after accusing IC to connect, can judge touch accuse to have / the judgement that not have. Set out from this, touch accuse IC to have advantage. But, default parameter is affirmatory, and the applied plan of the user is differ in thousands ways. Accordingly, the need below a lot of circumstances accuses parameter to do essence of life to refine to touching adjust, control function with optimizing those who use program to touch. Optimize if the graph is shown 2 times,touch the working environment that controls IC.

 

If the graph is shown 2 times, tuning software uses serial interface implementation to touch those who accuse parameter to adjust, write the parameter after optimizing through serial interface touch accuse IC. The parameter after be being updated for test and verify is using the integral property in the system, need joins advocate accuse MCU and touch accuse IC, run the control program in MCU. But, debugging aids and advocate accuse MCU common touch the serial interface that accuses IC, accordingly, need severs the link with debugging aids, go to serial interface switch advocate accuse MCU. Change character, when function of whole of parameter of test and verify, cannot pass the GUI of debugging aids, the effect after the intuitionistic parameter that monitor is adjusted.

 

 

Graph the 3 environments that adjust Rx130 application plan

 

The environment that adjusts Rx130 application plan is shown 3 times like the graph. Because Rx130 is used inside of buy touch accuse module to detect touch dominate an action, the serial interface that is used at communication (for example, UART) is used at mixing only communication of debugging aids Workbench, accordingly, although be in the process of parameter of a type of local school in ancient times of Rx130 carry travel, test and verify, still can pass serial interface, of will current parameter touch the GUI interface that accuses the effect to mirror Workbench, intuitionistic observation reachs convenient user the effect after parameter is adjusted.

 

 

 

 

 

Graph 4 touch plan accusing IC and Rx130 program program to burn collection

 

Burn written cost from the program, those who compare both is different. If the graph is shown 4 times, if the user is not used,hit the default parameter that accuses IC, use the parameter after combining specific application plan to optimize however, need to pass process designing so implement will newest parameter solidify arrives touch accuse IC. Especially when batch is produced, increased to burn collection touch the additional cost that controls IC. And in the Rx130 plan that right plan institute shows, need to will apply a program to burn only in recording Rx130.

 

 

From the angle of LED drive, compare the similarities and differences of both. Normally, touch accuse the buy inside IC LED Driver. If apply the need in plan to use LED to express to touch those who dominate an action,have / without, and use the structural design of the product, requirement LED is proximate touch accuse electrode, if the graph is shown 5 times, so use touch accuse IC the Layout of more convenient PCB.

 

 

Graph 5 touch accuse IC the Layout of more convenient PCB

 

But, be not all applied products, need to use LED to express to touch those who dominate an action to have / without, for example, touch simple and easily accuse Pad. Right now, use Rx130 touch accusing MCU is righter choice, because need not pay,use the recessive fee that touchs the place in accusing IC to contain LED Driver. Perhaps design a respect in the structure, need will express to touch accuse a movement to have / the LED that not have is far from touch accuse electrode, so also suggest to use touch accuse MCU, because touch,accuse MCU to have more bringing normally the foot can offer an alternative, convenient optimize PCB Layout.

 

 

The article is touched with Rx130 accuse MCU to be exemple, analysed simply touch accuse MCU and hit the respective good point that charges IC. When the user is developing particular applied product, choose to touch after all accuse IC, still touch accuse MCU, consider to touch the functional characteristic that accuses product oneself not only, the structural design that uses a product integratedly however, use environment, touch control performance demand, development / the judgement that debugs a lot of element such as periodic, cost to make.
