one company is asking 90 thousand Rs for providing readymade 0-300V 10Amps power supply..
for me 200V to 230V DC is enough at 10amps
- - - Updated - - -
i was thinking for time being for testing my load i can use
230Vac supply ---- > variac---> bridge rectifier ---> inductor 1mH --->...
Read ADc values
store in variable
use that variable in send message functions you created..
just printf() or serial output string is enough..
if you share your adc and gsm program i can tell where to change or add
i need DC supply which can give 10amp current
i have no experience in high volt high current power supply design..
i have designed only 5V 12V 1amp supplies and basically i am an embedded engineer..
I searched the net i got some 10amp circuits with parallel transistors to boost current but...
random read :--------- dummy write followed by current address read
Dummy write is except stop and data you give all things as it is..
{Start}{Devaddress + Wr}{memlocation addres} {Start}{Devaddress + Rd}{read the data+NACK}{stop}
multiplexing UART Tx RX pin to communicate with two modules
I am using GPS,Zigbee and GSM now all three requires UART.
I have 89v51rd2 and it has only 1 TX Pin and 1 RX pin.. (P3.1 and P3.0)
i tried to use CD4052 but it didn't work.. and other multiplexer i can use...
at least GPS and GSM i can...
you can use P0 for Data (external pullup required)
and P1 for control CS1 CS2 RW RST EN RS
Selects left 64 dots
CS1=1
CS2=0
Selects right 64 dots
CS1=0
CS2=1
Just to recreate in this post.....
I have found a camera with RS232 interface
its UCAM it is available in TTL and RS232 both versions
image size and quality can be change with simple serial protocol....
you add resistor in series at x+ and Y+...
you can start with 100ohms and then slowly increase till your ADC can recognize then minimum change in touch..
- - - Updated - - -
this happened because touchscreen was bad...
one should get resistance between at least two pairs..
(1,2) (3,4) (1,3)...
you can use P89V51RD2 it has SPI feature for general use apart from ISP

you can use P89V51RD2 it has SPI feature for general use apart from ISP
Based on these papers one can do a very wireless communication project or project on embedded system or project on Intelligent Public transportation system
