树莓派安装中文字库
树莓派安装中文字库
2020年12月16日
树莓派默认是采用英文字库的，而且系统里没有预装中文字库，所以即使你在locale中改成中文，也不会显示中文，只会显示一堆方块。
因此需要我们手动来安装中文字体。
好在有一个中文字体是免费开源使用的。
ssh中输入以下命令：sudo apt-get install ttf-wqy-zenhei
安装过程中如果碰到(Y/n)，都选择y
中文字库安装完成之后，还需要安装一个中文输入法。
输入如下命令sudo apt-get install scim-pinyin
一样的安装过程，安装完毕后输入
sudo raspi-config
然后选择change_locale，在Default locale for the system environment:中选择zh_CN.UTF-8,配置完成之后，输入命令sudo reboot
重启完成好就可以在VNC连接上去后使用中文显示和中文输入法了，切换中文输入法一样也是ctrl+space。

A MODULAR INHERENTLY NONFINITELY BASED LATTICE
A MODULAR INHERENTLYNONFINITELY BASED LATTICERALPH FREESE,GEORGE MCNULTY,AND J.B.NATIONIn[4]we gave a construction of inherently nonfinitely based lattices which produced a wide variety of examples.But none of these examples was mod-ular and we asked in Problem1for a modular example.Here we shall show that L∞of Figure1is such an example.Theorem1.L∞is an inherently nonfinitely based modular lattice. Proof.As observed in McNulty[6],a locallyfinite variety V offinite type is inherently nonfinitely based if and only if for infinitely many natural numbers N,there is a non-locally-finite algebra each of whose N-generated subalgebras belongs to V.We prove the theorem by establishing these facts. We assume the reader is familiar with the basic facts of modular lattices; see[1],[2],[5].Let B(for bottom)be the sublattice of L∞consisting of all elements of finite height and let T consist of all elements offinite depth.Of course L∞is the ordinal(or linear)sum B+T of these sublattices.Lemma2.The variety V(L∞)generated by L∞is locallyfinite.Proof.To prove this we need to show that for everyfinite n there is a bound on the size of the n–generated subalgebras of L∞.We do this by induction on n.Suppose that x1,...,x n are elements of L∞and let S be the sublattice they generate.We may assume that all of these elements either lie in B or they all lie in T since otherwise S is the ordinal sum of two sublattices with fewer generators.By duality we may assume they all lie in B.Thus each x k has a rank(or height)r k.Observe that if a and b are elements of B with ranks r a and r b and r b−r a≥4then the meet of all elements with rank at least r b is greater than or equal to the join of all elements with rank at most r a.So if we let r k be the rank of x k and(re)order the x k’s so that r1≤r2≤···≤r n then we may assume r k+1−r k≤3since otherwise S is a ordinal sum of sublattices with fewer generators.Thus S lies in an interval of L∞which has length at most3(n+2).All intervals of L∞offixed length have a bound on their size.Thus S is of bounded size.Let M3be thefive element modular,nondistributive lattice and let Z be integers as a chain.Let M3[Z]be the lattice of all order-preserving functions2RALPH FREESE,GEORGE MCNULTY,AND J.B.NATIONFigure1.L∞,an inherently nonfinitely based modular latticefrom Z to M3.If x∈M3letx embedds M3in M3[Z].(3)If v≺u in M3,then the interval[u]is1+Z+1(the ordinal sum).(4)If a is an atom of M3and0is its least element,then M3[Z]isgenerated by the constanst maps and the interval[a].(5)The(left)shift operatorσ[(σf)(i)=f(i+1)]is an automorphismof M3[Z].We wish do something similar with L∞and other modular lattices.So let L be a modular lattice.We start by forming M the lattice of all order-preserving maps from Z into L.This lattice is bigger than we want;weA MODULAR INHERENTLY NONFINITELY BASED LATTICE3 would like that intervals of L which are chains remain chains in M under the natural(diagonal)embedding(denoted x→v≤x≤a to4RALPH FREESE,GEORGE MCNULTY,AND J.B.NATIONa 2e 2Figure 2.L10cFigure 3.M 33needs to verify that every element of M 33[Z ]is either below a ,w h i c h i s s t r a i g h t f o r w a r d .A typical element of [b ]is c i ,where c i is the function c i (k )=a if k ≤i and b otherwise.Instead of using the identity map when gluing the two M 3[Z ]’s,we could use the shift map:c i →c i −1,obtaining a lattice M 33[Z ]∗.It is easy to check that M 33[Z ]∗∼=M 33[Z ].In L n −{u,v }there are two element of each odd dimension.We can arrange these elements into two chains s 1<s 3<···<s n −1and r 1<r 3<···<r n −1;see Figure 2.We have s 1<r 3and one can verify that every element in L n [Z ]is either in the principal ideal I generated bys 1and thus L n [Z ]is the Hall-Dilworth gluing of I and F .I is isomorphic to M 33[Z ].Let L n [Z ]∗be the result of gluing M 33[Z ]∗to F using the identity map on the interval [r 3].A MODULAR INHERENTLY NONFINITELY BASED LATTICE5Unlike the situation with M33[Z]∗,L n[Z]∗is not isomorphic to L n[Z].In fact L n has the sequence of transpositions[0,v] [a2,s3] [s1,b2] [e4,r5] [r3,d4]··· [u,1] ··· [r1,d2] [e2,r3] [0,v] where a i,b i∈[s i−1,s i+1]and d i,e i∈[r i−1,r i+1]are the four irreducibleelements of rank i,i even.Of course this defines an automorphism on[v]in L n[Z]but since the sequence of transpositions goes through the shifted interval,this automor-phism is the shift,sending each element x with v to its lower cover. Thus the sublattice of L n[Z]∗generate by L n and any element v is infinite(in fact it is all of L n[Z]∗,but we do not use this fact).In order to complete the proof of Theorem1it suffices to show that for each N we can choose n large enough so that the N–generated sublattices of L n[Z]∗lie in V(L∞)=V(L∞[Z]).As usual we view L n as embedded in L n[Z]∗by the diagonal map.Every element of x∈L n[Z]∗lies in a uniquely determined complemented interval[z x,t x]of L n of minimal dimension.z x is just the join of all elements of L n below x and t x is defined dually.Of course the dimension(in L n)of[z x,t x]is at most2.Thus we may assign to each element x of L n[Z]∗an lower and upper rank(the ranks in L n of z x and t x) and these differ by at most2.So if we let S be an N–generated sublattice of L n[Z]∗then an argument similar to the proof of Lemma2shows that, if S is linearly indecomposable,it lies in an interval[b]of L n[Z]∗where the dimension of[a,b]in L n is at most5(N+2).It follows that,for any N–generated sublattice S,if n>5(N+2)+4then either S lies in the filter[s1, ,s n−1]or is the linear sum of two such lattices.So it suffices to show that thisfilter and ideal are isomorphic to sublattices of L∞[Z].For thefilter this is straightforward since thefilter does not contain the shifted interval.Let I denote the ideal.To see that it is also embedable into L∞[Z]let P n be thefilter[s1,1]of K n.(Recall K n is L n with u removed.) Now I is isomorphic it K n[Z]∗and K n[Z]is naturally embeddable into B and so into L∞[Z].Thus it suffices to show that K n[Z]∼=K n[Z]∗.In P n every prime interval is projective with either[r1∨s1,s3]or[r1∨s1,r3], but not both.So P n is a subdirect product of two lattices,say Q and R,and P n[Z]is a subdirect product of Q[Z]and R[Z].So P n[Z]has an automorphismτwhich is the shift operator on one of these factors and the identity on the other.To makeτexplicit let x∈P n[Z]and let z x and t x be the element of P n defined above.If z x=t x then x∈P n andτ(x)=x. Suppose the dimension of[z x,t x]is1.If[z x,t x]projects to[r1∨s1,r3] then we apply the shift operator on[t x]to x;that isτ(x)is the unique upper cover of x in[t x].If[z x,t x]projects to[r1∨s1,r3]thenτ(x)=x. If the dimension of[z x,t x]is2then[z x,t x]is isomorphic to either M3or 2×2.In the former case if the prime quotients of[z x,t x]∼=M3project to [r1∨s1,r3]the we apply the shift operator to x,otherwise x isfixed.Finally6RALPH FREESE,GEORGE MCNULTY,AND J.B.NATIONif[z x,t x]∼=2×2and r and s are the atoms of[z x,t x],then x=(x∧s) andτ(x)=τ(x∧s).Now we defineρ:K n[Z]→K n[Z]∗.If x≥s1t h e nx≤r1,ρapplies the shift operator to x;otherwiseρ(x)=x.Since[r3]in K n[Z]∗is obtained from gluing two copies of M3by applying the shift operator to the top copy,ρrestricted to [r3]is an isomorphism.Finally one checks thatρis one-to-one and onto and that it preserves order and so is an isomorphism.This completes the proof of Theorem1.References[1]P.Crawley and R.P.Dilworth,Algebraic theory of lattices,Prentice-Hall,EnglewoodCliffs,New Jersey,1973.[2]B.A.Davey and H.A.Priestley,An introduction to lattices and order,CambridgeUniversity Press,Cambridge,1989.[3]R.Freese,J.Jeˇz ek,and J.B.Nation,Lattices with large minimal extensions,AlgebraUniversalis45(2001),221–309.[4]Ralph Freese,George F.McNulty,and J.B.Nation,Inherently nonfinitely based lat-tices,Annals of Pure and Applied Logic115(2002),175–193,online manuscript avail-able at:/∼ralph/papers.html.[5]Ralph McKenzie,George McNulty,and Walter Taylor,Algebras,lattices,varieties,Volume I,Wadsworth and Brooks/Cole,Monterey,California,1987.[6]G.McNulty,How to constructfinite algebras which are notfinitely based,UniversalAlgebra and Lattice Theory,Springer-Verlag,New York,1985,er,ed.,Lecture Notes in Mathematics,vol.1149,pp.167–174.University of Hawaii,Honolulu,HI96822E-mail address:ralph@University of South carolina,Columbia,SC29208E-mail address:mcnulty@University of Hawaii,Honolulu,HI96822E-mail address:jb@。

the router path$route add default gw10.64.64.64or your gateway XX.XX.XX.XXThen have a test$ping 3.4WDT3.4.1Block Diagram of WDTThe WDT module have three terminals,input ,output and LED indicator.Note:The LED is optional and not available in earlier hardware version.3.4.2How it works1.System POWER ON.2.Delay 200ms.3.Send WDO a negative pulse with 200ms low level to reset the system.4.Pull up WDO.5.Delay 120seconds while the indicator flashing(typical 1hz).6.Turn off the indicator.7.Wait for 8pulses at WDI to active WDT module and light the LED.8.Get Into WDT-FEED mode ,at least one pulse should be feed into WDI in at least every 2seconds,if not,the WDT module should output a negative pulse to reset the system.9.Goto 2.3.5RTC3.5.1The chip of RTC is MCP79410from microchip.It is mounted on the system I2C bus.The OS itself has the driver inside,only we need are some configurations.3.5.2Open/etc/rc.local AND add2lines:echo"mcp7941x0x6f">/sys/class/i2c-adapter/i2c-1/new_devicehwclock-sThen reset the system and the RTC is working.Note：1.make sure the i2c-1driver point is open,and the point is closed default.2.the estimated backup time of the RTC is15days.3.10UPS for safe shut downThe UPS module diagram is listed below.The UPS module is inserted between the DC5V and CM4,a GPIO is used to alarm CPU when the5V power supply is down.Then the CPU should do something urgent in a script before energy exhaustion of super capacitor and run a“$shutdown”Another way to use this function is Initiate a shutdown when GPIO pin changes.The given GPIO pin is configured as an input key that generates KEY_POWER events.This event is handled by systemd-logind by initiating ashutdown.Systemd versions older than225need an udev rule enable listening to the inputdevice:Use/boot/overlays/README as reference,then modify/boot/config.txt. dtoverlay=gpio-shutdown,gpio_pin=GPIO22,active_low=1NOTE:The alarm signal is active LOW.4.Electrical specifications4.1Power consumptionThe power consumption of the EdgeBox-RPI4strongly depends on the application,the mode of operation and the peripheral devices connected.The given values have to be seen as approximate values. The following table shows power consumption parameters of the EdgeBox-RPI4:Note:On condition of power supply24V,no add-on card in sockets and no USB devices.4.2UPSThe backup time of UPS module is very depend on the system load of the system.Some typical conditions are listed below.The test module of CM4is4GB LPDDR4,32GB eMMC with Wi-FI module.5.Mechanical DrawingsTBD。
