Embodiment 1

[0015] The boot system composed of single-chip microcomputer, touch manager and touch screen, its composition includes: mixed signal single-chip microcomputer C8051F020 1, touch manager ADS7843 2, touch display screen 3, P0.0 to P0.3 of described mixed-signal single-chip microcomputer C8051F020 and touch The SPI interface of the manager ADS7843 is connected. The mixed-signal microcontroller with two software-programmed power management modes of idle and shutdown uses the idle mode. The touch manager is a touch voltage signal that converts the two coordinates of the touch screen It is an integrated circuit chip for digital signals, uses SPI bus for management and data communication, and is started by pen interrupt.

[0016] The start-up system that described mixed-signal single-chip microcomputer, touch manager and touch screen constitute, should enable SPI bus part in mixed-signal single-chip microcomputer C8051F020, the idle mode selection bit (PCON.0) of power control registe...

Embodiment 2

[0019] A mixed-signal microcontroller C8051F020 and touch screen [2] The basic system constituted, its boot part includes touch screen, touch manager ADS7843 [ , SCM interface and CPU working mode special register

[0020] The mixed-signal microcontroller C8051F020 has a 51-series compatible CIP-51 core. It has two software-programmable power management modes: idle and shutdown, which are set by the power control register PCON. In idle mode, the CPU stops running while peripherals and clocks are active. In Halt mode, the CPU stops running, all interrupts and timers (except the Missing Clock Detector) are inactive, and the system clock is stopped. Due to the use of external devices to start the microcontroller, only the idle mode can be used.

[0021] The touch manager ADS7843 is an integrated circuit chip that converts the touch voltage signal of the two coordinates of the touch screen into a digital signal, uses the SPI bus for management and data communication, and start...

Abstract

The invention relates to a starting-up system comprising a single chip computer, a touch manager and a touch screen. One basic module of an electric control system is a starting-up part. A special power switch is used in a universal method. The special power switch has simple structure and direct function. However, the position and the volume of the power switch also bring difficulties to the structural design in a hand-held system. The starting-up system comprises a mixed signal single chip computer C8051F020 (1), a touch manager ADS7843 (2) and a touch display screen (3), wherein, the P0.0 to P0.3 of the mixed signal single chip computer C8051F020 is connected with an SPI interface of the touch manager ADS7843, and the mixed signal single chip computer having two power management modes of idleness and stop of software programming uses the idleness mode; the touch manager is an integrated circuit chip converting the touch voltage signals of the two coordinates of the touch screen into digital signals, uses an SPI bus to carry out management and data communication and carries out starting by pen interruption. The invention is applied to the field of the electric control system.

Description

Technical field: [0001] The invention relates to a boot system composed of a single chip microcomputer, a touch manager and a touch screen. Background technique: [0002] A basic module of the electronic control system is the boot part. A common method is to use a dedicated power switch. It is simple in structure and direct in function. In the handheld system, the position and volume of the power switch also bring difficulties to the structural design. Invention content: [0003] The object of the present invention is to provide a booting system composed of a single-chip microcomputer, a touch manager and a touch screen, which has a simple structure design and saves components. [0004] Above-mentioned purpose realizes by following technical scheme: [0005] The boot system composed of single-chip microcomputer, touch manager and touch screen, its composition includes: mixed-signal single-chip microcomputer C8051F020, touch manager ADS7843, touch display screen, P0.0 t...
