Thanks for this will have a look and let you know how i get on.

Hi Martin

Thanks for the reply I would really appreciate the sample code so I can see how you implement this. I will need to convert most of the Ascii table as I'm sending a long SMS in pdf format

Hi Guys

I'm trying to convert a Text message to Hex so I can send an SMS in PDU Mode, I have searched and searched but can't seem to find a formula or an example with no luck. I know that with 1 to 9 you would add 30 but from there I'm really lost.

Hi, Guys
Has anyone got any ideas on how I will send an SMS that is longer than 160 characters

Hi Leigh

Thanks, I knew I was doing something small wrong it's working like a dream

Hi Guys

I'm a bit confused with the internal addressing. If the eeprom address starts at 0 and the eeprom can do a 64 byte page read / write then 0 to 64 is 63 or am i missing missing something? or should me next address start address be 65

The one address is 0xa0 (1010 0000)and on the board i have A0 A1 A2 all tied to ground on the...

Thanks Ben I did that and it changed the Display but now i get a mismatched error when compiling E-P_I2CU6E0V46-PIC18LF47K40_256kOBM_6_USERS7_9Trigger_Master_NDTest.c: 1136: (764) mismatched comparison (warning) what should i do to to rectify this? I have tried replacing the display as instructed an...

Hi Ben

Everything now seems to be working

Hi Ben Just got my new chips the PIC18F47K40 and it dose not seem to work for some reason in my test program the 1Hz timer interrup works but in the loop it sends the UART TX every +- 10 seconds witch is very slow as i have no delays. Also if i set the FAT1 to channel 1 i get the flowing compilation...

Hi Ben

Everything seems to be working now and i can read the UART on my PC using USB to RS232 adapter so not sure what was wrong yesterday. One question how dose the auto-band detect work on this chip?
