I’m using a LPC2106 to connect and drive several peripherals. My project is to build a cellphone accessible to disabled people. For that, I’ll be using a bright display and a large keypad, both connected to the LPC2106. This is a school project (for my master in electrical engineering), so I will only add a display and a keyboard. But we need to be able to add other peripherals (for someone else’s master probably), which means that I won’t have enough GM862-GPS GPIOs. So we’re using the LPC2106, its 2 UARTs, its SPI and I²C interfaces.
Do you have a better idea of the functionnalities the LPC2106 will probide? I want to apologize for my English, which is not my first language.
It sounds like the LPC2106 will be providing the interface between the user and the GM862 module and as such it will need to send commands to the module. As I see it, you would use one of the UARTs on the LPC2106 and connect it to the modem serial port on the GM862. To download code you could either send it through the LPC2106 or you could design your hardware so that you could have direct access to the GM862 from a separate serial interface. But it seems to me that this would be unnecessary as you most likely would not be running a Python script on the GM862 since the LPC2106 is going to be controlling the module.
Sounds like you need to give the design some more thought as to exactly which component is going to do what.
Actually, my idea was the opposite. I was thinking I could use a Python script to send commands from the GM862 to the LPC2106, via a serial port. The LPC2106 will indeed provide the interface with the user and the GM862 module.
This is the reason why I need 3 serial interfaces on the GM862-GPS module :
Running the GPS
Loading Python script
Sending and receiving information to the LPC2106
I am thinking about the design now, nothing is definitive!!
I’m a beginner with the Telit modules (GM862-GPS using the EZ10-PCS) and Python scripting. I wrote a small script that should send “test” to the serial port (ASC0).
import SER
import MDM
import MOD
import GPIO
SER.set_speed('115200','8N1')
SER.send('test\r\n')
I’m using the main serial port to download scripts to the module; after it is downloaded I use the MDM lib to set the DTR to ‘0’
<res = MDM.setDTR(0)>. I tested the <res = MDM.setDTR(0)> command with other scripts and it works. The module should run the script with the next reboot. I then run HyperTerminal and reboot it with the AT#REBOOT command, It reboots but HyperTerminal is not receiving “test”.
i am also having same problem could not get any response on COM1 hyperterminal/Rterm .
i have also used SER to send somethig to ASC0 i.e physically connected to COM1 hope i am right in that case one should get response buy unfortunately getting nothing on screen
I resolved the problem I had with the SER command not getting through to Hyper Terminal.
My solution was very simple
Just make sure your “GM862-GPS using the EZ10-PCS” or “GM-862-GPS EVK v3 RS232 kit” are unplugged from you PC’s com port when you boot it up, otherwise it will go into AT command mode and will not run you Python script.
After you are sure the module booted up and the script is running plug it into the com port and refresh your HT.
Hope that does the trick, feel free to ask if this did not do the trick.
