i want output 2 different analog values 10 bit resolution i.e. dac_value ranging 0-1023. using atmega16 external crystal 4mhz. have tried connecting rc filter @ output nothing changed. getting 0 output, can ?? #include <avr/io.h> #include <avr/interrupt.h> void initpwm() { tccr1a |= (1<<wgm11) | (1<<wgm10) | (1<<com1a1) | (1<<com1a0) | (1<<com1b1) | (1<<com1b0) ; tccr1b |= (1<<wgm12) | (1<<cs10); } uint16_t dac_value1 = 100, dac_value2 = 200; int main(void) { initpwm(); while(1) { ocr1a = dac_value1; ocr1b = dac_value2; } (;;) {} } you assigning wrong bits wrong registers. clarify: pwm not analog output. changed high or low output state. pwm value determines how long output in each state (high or low) withing timer period. if want make "analog" output, need filter output signal, example, passing thru rc-filter, need make output fast possible, that...

i have spring integration 4 bean method following signature: @component public class aservice { @serviceactivator public message<?> servicemethod( message<?> message, @header(serviceheader.a_state) astate state, @header(serviceheader.a_id) string id) { ... } ... } at moment, call service method within spring integration java dsl (spring-integration-java-dsl:1.0.1.release) flow this: .handle("aservice", "servicemethod") this works absolutely fine but, wondering whether possible call service method in following sort of way: .handle(message.class, (m, h) -> aservice.servicemethod(m, h)) the reason call service method in sort of manner that, when looking @ code using ide such eclipse, can drill service's method example highlighting method , pressing f3. so question is, there alternative way calling @serviceactivator method (which includes @header annotations) without us...

following part of stored proceedure im using extract data db. query begin set @sqlstring = concat("select b.id, c.name, c.accountid,, b.total_logs, a.time_start, a.time_end ,count(a.id) number_of_users ",logtable," inner join users b on a.id = b.id inner join accounts c on b.accountid = c.accountid group id;"); prepare stmt @sqlstring; execute stmt; end at times in db, logtable(table passed in variable logtable_1, logtable_2 .... ) can non existent, when perticuler table missing crashes , throws error because a.time_start, a.time_end cannot have values without log table. but want assign null on values a.time_start, a.time_end without throwing error, so can body tell there way modify code like begin if logtable exists \\ query else \\ query end find existence of table querying information_schema.tables . if returns count equals 1 can proceed executing query on table. otherwise go else block. sample : declare tab...

hello ask how create multiple views programmatically , show them on screen, have tried there missing. int x,y; x= 0; y=50; (int i=0; i<4; i++) { uiview *view = [[uiview alloc] initwithframe:cgrectmake(x, y, 300, 100)]; view.backgroundcolor = [uicolor redcolor]; [self.view addsubview: view]; y+=40; } int x,y; x= 0; y=50; (int i=0; i<4; i++) { uiview *view = [[uiview alloc] initwithframe:cgrectmake(x, y, 300, 100)]; view.backgroundcolor = [uicolor redcolor]; view.layer.cornerradius = 5.0f; [self.view addsubview: view]; y+=140; //y next view should height of previous view , margin between view }

i have ui thread enables user set properties of entity. i have worker threads automatically modify properties of entity that, importantly, user not have access to. would safe have different dbcontexts per thread , depend on programming avoid modifying same property , attempting savechanges() on context has same entity modified in different ways? or there safer way of doing this, i.e. way in possible programmer day change code such same property modified 2 different contexts safely? or latter situation 1 programmer has careful/refactor around? theoretical part there three ways resolve concurrency issues in multi-threading environment: pessimistic , can done locks item being edited - no 1 else can edit item being edited. hard implement approach, , way quite bad performance view - editing threads waiting single writer, , wasting system resources. optimistic , default way resolve issues. main idea continue operation until have success. there lot of algorithm in...
