Hello everyone,
maybe anyone here is familiar with a way of making one stack memory for few tasks? Problem is that even if I'm defining one memory area for few tasks which runs for a short time and never runs at same time compiler makes few different allocations for them.

have all the answers u ever want about all the things atmega8 does, if u need other than atmega8. write your AVR name in google search window. press search and open 1st *.pdf u see.
if want something what is already writed in that datasheet here is some...
from what I see in that datasheet these chargers r not good for you. since they charge up to 4,2V and in your case u would need 3,65V (correct me if I'm wrong) and for 4 cell pack you need to dissasemble that pack in a way to charge cells individualy with this type of charger. for pack you would...
in I2C ea byte have extra bit(ACK), so if u will run @400Khz u will achieve 355,(5) Kbit per sec speed max. so for 400Kbit per sec. you need 450KHz frequency.
yes. and very easy. Go buy USB<>SATA/ATA (depending on your HDD) box. Put HDD inside it as described in user manual, plug power supply (3.5' HDD boxes usualy requaers external power supply, if 2,5' or 1,8' HDD probably won't need external power supply), plug USB wire one side to box other to PC...
seems that you trying to charge litium with constant voltage. if your voltage won't go higher than max charging battery voltage it will work. but as u said it is taking ages. it will be that way. for max voltage alowed for lithium it depends on chemistry, so to find out look for battery...
Hello everyove,
maybe anyone are familiar with way of getting all variables used in programs with theis sizes? Is there a way to do that in uVision3 or is it possible to do that with any other program?
To be more exact what I need, I will explain my problem a bit. I have code of certain...
Hello eeryone,
one question apeared while trying to make full I2C(TWI) interupt based driver. main problem is after transmitting nACK when I can set it back inside ISR(); and don't leave I2C hanging with nACK in register that way uC being isolated from i2C line.
case 0x40: //SLA+R has...
Hello everyone,
maybe anyone could comen about schematics I atached below ability to work as DC<>DC converter. Would be working close to same U on both ends, only use of it is to transfer energy from one side to other up to request.
Also maybe anyone have any oter offers how to do what I...
Hello everyone,
can anyone coment about how these schematics would act? And would they do that in order I think they should
Also maybe anyone have any other offers on making simple constant U/I schematics which are prooved working. Requaerments are same: constant u - 10-80V range to 5V up to...
Hello everyone,
Was wondering if anyone can explain interupt handler actions in case of enabling interupt with interupt source flag already set.
To be more precise processor - LPC2368, fragment of code;
