Hey,
You should select a phone which supports AT commands, which almost every phone available do. So, you should not have any problem. As for, the Text and PDU mode, you should send a command AT+CMGF=? to the phone to know whether it supports these modes or not.
If the response is (0,1), Then...
Re: Converting 3V to 5V
Hey,
We cannot use the pull-up resistors because the voltage source here would be the output ports of my ARM processor, i.e. at 3V. Pull-up resistors cannot pull the voltage up until they have an appropriate source connected to it. Ever heard of a resistor generating 2V...
Re: Converting 3V to 5V
Thanks Brian,
I havent tried it yet, but I am pretty sure it'll work. Would you recommend any specific tansisitor or any vendor's would do?
GSM and CDM
if u want to make ur project in GSM, you should select at least select what you want to do.. If you want to work on a GSM-modem or GSM programming then I suggest you read GSM AT commands first.
Re: Converting 3V to 5V-- need help again
Hi,
I looked into the datasheet of 74LVC4245 and it seemed like the apt IC, but all of the vendors offer this product in SSOP packaging. Since I am developing my project on a general purpose PCB, it will be very difficult for me to solder an SSOP IC. Do...
Hello,
I am trying to drive a LCD with an ARM procesor kit. The output of ARM7 ports is 3V and the LCD requires 4.5-5V to operate. Can anyone tell me any device that could achieve a 3V to 5V converstion accurately. It could be a regulator since I might be using the LCD with a...
