Hi everyone!
I'm not sure if this has been asked before. I've tried interfacing a SD Card to a microcontroller with a very fast read/write cycle (i'm writing data every second). After days of continuous run, I noticed that the performance degrades. My question is, is FAT the only available...
Hi there!
Say, I was able to successfully send a command to a base station using GPRS (although I haven't really tried it), how does the data sent appear in the server? I mean, are they like web pages, etc...?
This is really new to me.. Just some idea please.. thanks a lot!
Thanks for the reply =)
Actually, my mcu has several uart pins and I can actually go with the task by using the other uart pins. If there's no any other solution, perhaps, I'll really have to settle with that.. =(
Thanks again..=)
If you are going to connect the sim340 module and the pic mcu, i think, you can directly connect the module with the mcu. the gsm module has pins (rx, tx, gnd, etc) that accepts ttl. so it can accept inputs from the mcu even without the max232 converter. you'll only need the rs232 connection if...
hi everyone!
I really need some help here... I want to control multiple GSM Modules using just one UART, but I can't find a good way of doing it. I'm using a SIM340DZ gsm module.
My original plan was to multiplex sim holders but it doesn't seem to be a very good idea due to some standard...
i've used pic18F2585.. from CAN, I pass the data to Uart and viewed using the hyperterminal. to get the USB interface, you can connect the RX and Tx pins of the UART of mcu to the pins of USB. There are four pins for USB (Rx, Tx, Vcc and Gnd).

hi again! what mcu are you using?
in "the i2c pins and jtag pins are multiplexed" do you mean the i2c and jtag are in same pin? Isn't there a way to select just one of them to function? (in Zds, some pins perform multiple function and you select what you want by setting the alternate function)...

Re: gps and gsm
Hi GSM Man!
Do you know if the SIM340 GSM Module supports SPI interface? And if yes, do I also control the module with AT commands fed on the SPI lines? I'm not sure how to do it this way since I usually communicate with GSM using UART. I actually plan to control multiple GSM...
