Graphics & LCD

using 2 lines together to show large fonts on 2x16 or 4x16 lcd

Dear Sir,

Normally, a character LCD has 8×5 dots character size, but is there any library which allows you to combine two rows to make larger fonts using the same 8×5 dots character LCD, this library should work on 16×2, 20×2, 16×4 and 20×4 Character LCDs, using the 4 bit data bus.

Measurement

Frequency Counter for Antenna Analysis (up to 400Mhz) using PIC18F4550

Hello all!
Happy new year!

I saw somewhere we can use a combination with Timer0, Timer1 and prescaler values to make a frequency conter up to UHF bands.

Could anyone point me towards the light?
Tried to search in the net but all I've found is up to 50MHz.

The main idea is collect 3 voltages via ADC and the frequency. Then, send them all via USB to a PC.

Thanks in advance!

GSM / GPRS

GSM2 Click : HTTP POST ?

Hi guys,

with the GSM2 Click module, I managed to send SMS but unfortunetely I did not find the right way to push "HTTP POST".
I tried the following:

AT+QIFGCNT=0
AT+QICSGP=1,"Orange F"

AT+QIREGAPP // Start TCPIP Task
AT+QIACT // Activate GPRS

AT+QHTTPURL=26,30
http://xxx.xxx.xxx.xxx:1234

AT+QHTTPPOST=7,10,10 //Send HTTP GET Request
gps=x,y
AT+QHTTPREAD=30 //Read the response of HTTP server.
AT+QIDEACT

but it hangs during QHTTPPOST ... any idea ?
THANKS a lot
