Referring to Fig. 3, micro controller module of the present utility model selects to use the MMC2107 microcontroller (U1) of MOTOROLA company, and its support circuit is as follows:
Data wire: when design, adopted 16 FPDP, 16 data lines are D[31:16].
Address wire: used A[15:1], reason is that the SRAM space is 64KB, and the address is 16 alignment, so address A0 need not connect.A[7:3 in these address wires] link the address wire of FPGA (U5) simultaneously as FPGA, A2 is also as the A0 of liquid-crystal controller.
Chip select line: CS#0 is as the sheet choosing of FPGA, and FPGA takies the low 8MB of microcontroller external address space like this; CS# 1 is as the sheet choosing of SRAM, and (U15 U16), takies the address space of 8~16MB to link 62256; CS# 2 keeps; CS# 3 is as the sheet choosing of liquid-crystal controller 13305 (U12), and liquid-crystal controller takies the address space of 24~32MB.
The edge interrupts the pen interruption of (INT#0~7): INT#0 as touch screen controller; INT#1 uses as the interruption of FPGA; INT#[3:2] as the input of button; INT#[7:4] be used for simulating DCD#, RI#, DSR#, the CTS# signal of MODEM;
Reset circuit: 2107 output RSTOUT# begin configuration for FPGA, FPGA, and configuration finishes back FPGA and provides CON_DONE, and CON_DONE links RESET, reset 2107 and system again, thereby have constituted the dual reset circuit.
Gather indication: driving a light emitting diode with the PE5 pin, is at present green.
Referring to Fig. 4, the configuration module that resets of MMC2107 mainly be operator scheme, clock source and clock module, chip output pin to MMC2107 output intensity, the guiding device that resets, inner FLASH module etc. be set select.
The configuration sampling of MMC2107 mainly is that 9 pins are sampled.The VDDSYN pin is the power supply of clock module, is 3.3V when resetting automatically, and other 8 pins are data wires, requires to finish the back in configuration and discharges data/address bus, so select for use ternary double buffering 74LV244 (U3) to be provided with.
(R27, R28's 0 ohmage when being configured to holotype among the R23~R210) need burn-on, and other 0 ohmage does not need welding, and the corresponding pull-up resistor of path that has welded 0 ohmage need not weld.
Referring to Fig. 5, the data acquisition of data acquisition interface module is actually by the J10 interface carries out the A/D conversion to the ECG simulator signal of sending here from collection plate, utilizes the QADC in 2107 to realize translation function.
Referring to Fig. 6, (U15 U16) constitutes the SRAM module, and U15 directly links to each other with MMC2107 with U16, expands 128K bytes of memory space by two 62256.
Referring to Fig. 7, the FLASH memory module mainly by FPGA (U5) and FLASH (U7, U9) memorizer is formed, FPGA uses as the interface between MCU and the FLASH, all need the intervention of FPGA to the operation of FLASH.What originally use is the FLASH chip of 64MB, changes the chip of 128MB now into, the pin of chip compatibility of two kinds of models.
Referring to Fig. 8, LCD MODULE by display-memory 62256 (U10, U11), display controller 13305 (U12) and 74L04 (U400) and 74L32 (U401) form.Two 62256 (64KB) comprise character generator as video memory.Attention: in print circuit pattern, added two resistance R 51 and R52 pull-up resistor as two 62256 chip select lines, attempt when 62256 do not work sheet chosen that to draw be 1 so that reduce power consumption, in fact do not reach this effect, do not have this two resistance in the schematic diagram, do not weld this two resistance on the present circuit board yet.Crystal oscillator used 8MHZ originally, and in order to reduce power consumption by reducing refreshing frequency, what use now is the crystal oscillator of 6MHZ, and effect meets the requirements.
Note selecting 13305 storage address: when design, select the D[23:16 of MMC2107] as the data/address bus of S1D13305, according to the regulation of EBI module, D[23:16] corresponding byte address is odd address (that use in the current procedure is ADDR[1:0] value be " 01 ").What S1D13305 determined that MMC2107 writes it by A0 itself is order or parameter (data), therefore when giving S1D13305 allocate memory address, should consider with any root address wire as A0, and use that chip selection signal to select as the sheet of S1D13305.Adopt the A0 of the A2 of MMC2107 as S1D13305, select the chip selection signal of 3 (CS3#) with sheet as S1D13305, therefore distribute to two storage address: 0x8,180 0005 of S1D13305 and 0x8,180 0001, the former is write order and read data address, the latter is for writing data and read states tag addresses, all read/write operation carried out in these two addresses to S1D13305 write order, parameter, data or from the S1D13305 read data.
Referring to Fig. 9, the touch screen input module: the touch screen input module is put forward interrupt requests by 7846 (U4) to 2107, then in interrupt handling routine 2107 to 7846 measuring command, obtain contact coordinate.
Measure the touch point coordinate time and must select suitable SPI clock frequency could cooperate the sequential of ADS7846, proper when the external clock (SPI clock) of discovery ADS7846 is 50KHz~60KHz in measuring process.
In measuring process, need disappear to the touch process and tremble processing, when pen interrupts taking place, do not measure coordinate immediately but postpone 300ms and read interrupt identification again, if interrupt identification still is 1 (has and interrupt taking place), carry out measurement of coordinates this moment again.
When measuring, earlier at the coordinate figure of the equidistant several points of measurement on the basic vertical straight line and on the straight line of a basic horizontal, no matter from table, be that vertical direction or horizontal direction are all linear basically as can be known.Can get Y changes in coordinates slope is 46.33/mm, and the slope of X coordinate is 64.25/mm.According to application need touch screen is divided into the touch piece of 8 * 16 pixel sizes, totally 40 * 15=600 touches piece, thereby the granularity chap is more conducive to practical application.The size of utilizing the touch piece to adjust slope again makes it be more suitable for the needs of practical application.
