UPD16682A along catches in each serial clock39。 But when A0 level for low, then thought what receives is a display control order. May realize using the uPD16682A control mand to the uPD16682A majority operation controls.uPD16682A and MSP430F149 hardware interface designssystem uPD16682A and the MSP430F149 hardware interface schematic drawing. In the chart the system uses the 4MHz crystal oscillator, and obtains the clock which by the system clock frequency division other in peripheral devices use. MSP430F149 and uPD16682A connect the I/O mouth is defined as the output, after MSP430F149 uses the internal 12 A/D gathering sensor transforms the voltage signal. After program processing, transmits orally through above I/O delivers uPD16682A to carry on the information demonstration. Because the actuation liquid crystal display39。顯示RAM的每一位對(duì)應(yīng)顯示屏上的一個(gè)點(diǎn),總共可以存儲(chǔ)13265點(diǎn)的信息;通過(guò)選擇對(duì)應(yīng)的RAM頁(yè)地址和列地址,微控制器可以訪問(wèn)其中的任何一個(gè)點(diǎn)。2. uPD16682A與微控制器的接口uPD16682A可以通過(guò)8位雙向數(shù)據(jù)總線(并行模式下)或者通過(guò)串行總線接收來(lái)自微控制器的數(shù)據(jù),這兩種模式可以通過(guò)將其P/S引腳置高或置低進(jìn)行選擇。此時(shí)uPD16682A內(nèi)部顯示RAM的數(shù)據(jù)訪問(wèn)是單向的,即微控制器只可以向顯示RAM寫(xiě)數(shù)據(jù)以刷新液晶顯示的內(nèi)容,但不可以讀取顯示RAM的內(nèi)容。對(duì)控制信號(hào)線A0的讀操作由uPD16682A的內(nèi)部定時(shí)器來(lái)控制,在每隔8個(gè)串行時(shí)鐘之后自動(dòng)操作一次。5. uPD16682A與MSP430F149的硬件接口設(shè)計(jì)系統(tǒng)uPD16682A與MSP430F149的硬件接口圖系統(tǒng)采用4MHz晶振,并由系統(tǒng)時(shí)鐘分頻得到其它內(nèi)外設(shè)所用的時(shí)鐘。uPD16682A采用內(nèi)部4倍壓連接方式。經(jīng)程序處理后,通過(guò)上述I/O口傳送到uPD16682A進(jìn)行信息顯示。當(dāng)A0電平為高時(shí),認(rèn)為接收到的是一個(gè)顯示數(shù)據(jù);而當(dāng)A0電平為低時(shí),則認(rèn)為接收到的是一個(gè)顯示控制命令。UPD16682A在每個(gè)串行時(shí)鐘的上升沿將串行數(shù)據(jù)捕獲到其內(nèi)部的移位寄存器,同時(shí)計(jì)數(shù)器自動(dòng)加1。此時(shí)uPD16682A內(nèi)部顯示RAM的數(shù)據(jù)以刷新液晶顯示的內(nèi)容,也可以通過(guò)數(shù)據(jù)總線讀取顯示內(nèi)存的內(nèi)容。從微控制器讀入的顯示數(shù)據(jù)按照D7~D0的數(shù)據(jù)位順序與液晶顯示屏的行順序一一對(duì)應(yīng),其顯示關(guān)系對(duì)應(yīng)圖如圖1所示。該產(chǎn)品采用+3V單電源供電,內(nèi)置升壓電路并具3倍壓和4倍壓兩種工作模式,支持8位串行或并行數(shù)據(jù)的輸入,內(nèi)置時(shí)鐘發(fā)生電路和程序可編程控制的偏壓電路。s rise along, has received the interior 8 serial bit data to transform 8 parallel data。s corresponding port. This time the uPD16682A interior demonstrates RAM the data by the refurbishing liquid crystal display content, may also through the data bus read demonstration memory content. When works under the serial pattern, uPD16682A only uses data line D6 to input the serial data, namely the serial main line39。s RAM page address and a row address, the micro controller may visit any spot. The micro controller carries on (under serial pattern to the uPD16682A demonstration RAM readwrite operation through the uPD16682A I/O buffer uPD16682A not to support reads operation), and should read the operation and the liquid crystal display monitor driving signal read operation is independent, therefore, when at the same time demonstration memory data by bilateral visit, will not present displayed information phenomena and so on vibration. Demonstration data which reads from the micro controller according to D7~D0 data position order and liquid crystal display monitor39。}附錄二 系統(tǒng)原理圖外文資料翻譯Iiquid Crystal Display Driver UPD16682A SynopsisuPD16682 is the liquid crystal display driver which NEC Corporation at the beginning of 2001 promoted, this product builtin demonstrated the RAM memory large capacity, and could provide 13265 the lattice entire spot demonstration, the especially qualify used in 1616 or 1212 in the lattice, the Japanese character display。j0。 0x01) I2C_Set_sda_high();else I2C_Set_sda_high();for(j=30;j0。 int j。i++){ if(nValue amp。下面為具體的程序。i++){ *pLCD=pBuf[2+i]。 //指向LCD顯示存儲(chǔ)器 Char *pLCD=(char *)amp。本次使用單片機(jī)設(shè)計(jì)其實(shí)是一個(gè)軟硬件結(jié)合的設(shè)計(jì)。在很多實(shí)際應(yīng)用中,只要對(duì)電阻測(cè)量系統(tǒng)的程序和硬件電路加以一定的修改,便可以得到很實(shí)用的電阻測(cè)量系統(tǒng),從而應(yīng)用到實(shí)際工作與生產(chǎn)中去。 } int getGain(void) { return gain。 } //增益為1000 If(nValue 1000) { P1OUT = 0x00。 } //增益為10If(nValue == 10) { P1OUT =
