Problems solved by technology
The virtual host calls the underlying I 2 The display speed of the C driver function is relatively slow, and can only reach a transmission rate of more than ten Kbps. Experiments show that it is possible to display a small-size LCD with monochrome, but the display speed of a 2.0-inch CSTN is very slow, and usually displays a screen of data. takes about 20 minutes
Therefore, because the driving display speed provided by this system is slow, and it can only drive monochrome display, it cannot perform color display such as CSTN, TFT, etc., and it does not support the keyboard input function of the general matrix keyboard circuit. Meet the development requirements of current electronic information products

Embodiment Construction
[0021] The invention is an innovative development of a single Bluetooth chip, boldly breaking through the application mode or application system provided by a single Bluetooth chip provider, and realizes fast color display and keyboard input management on a single Bluetooth chip, so that the single Bluetooth chip can be maximized Therefore, it saves the cost of the same application and greatly saves the space of the application product and reduces the volume of the application product.
[0022] For ease of description, the present invention uses a single Bluetooth chip with the model number BC352239A-IVQ-E4, which is a BlueCore3-Multimedia External Bluetooth main chip, and the single Bluetooth chip has:
[0023] 1. 16-bit microprocessor, but not open code and microprocessor platform;
[0024] 2. 24-bit Kalimba DSP processor open platform, 32MIPCS processing speed;
[0025] 3. BLUETOOTH V1.2 transceiver circuit and baseband processing circuit;
[0026] 4. Audio codec circuit.
[0027] Su...

The invention discloses colour display and keyboard input management system and method based on a single Bluetooth chip. In the method, a line output circuit and a row input circuit of a universal keyboard matrix circuit are respectively connected to PIO (Programmed Input Output) interfaces provided by the single Bluetooth chip, and an LCED is connected to three PIO interfaces of the single Bluetooth chip through a three-line serial interface circuit, therefore, a DSP (Digital Signal Processor) open platform inside the single Bluetooth chip controls the PIO interfaces, a DSP processes processing and displaying data of the open platform, and the PIO interfaces drives the LCDdisplay to display the data through the PIO interfaces. The invention breakthroughs an application mode or an application system provided by a Bluetooth chip provider and ensures that the single Bluetooth chip is furthest developed and utilized, thereby saving the cost of equivalent application, greatly saving the space of the application products and reducing the volumes of the application products.
Description
Technical field [0001] The invention relates to an application system of a single Bluetooth chip, in particular to a color display and keyboard input management system based on a single Bluetooth chip and a corresponding management method. Background technique [0002] In recent years, Bluetooth technology products have been widely used, such as Bluetooth headsets, Bluetooth hands-free, car Bluetooth phones, Bluetooth mobile phones, etc. The cost of Bluetooth technology products is getting lower and lower, and the scope of application continues to expand. The functions of a single Bluetooth chip (IC) have also been continuously enhanced. However, because the current Bluetooth chip technology is in the hands of foreign companies, foreign companies often do not disclose the original code of the Bluetooth chip. While selling the chip, they sell various products based on the Bluetooth chip. Kind of application software. For example, the BlueLab3.6.2 development kit of CSR in the Un...
