Hello Everyone,

i am working on the EFM32 EB and TELECOM DESIGN TD1204 my objective is to write the program for gps and accelerometer detection by using the this controller

can anyone help me to write the program and i have just wrote the simple LED blinking program but it shows me some error

Post the datasheet of the device you're trying to communicate with.

Re: Requesting to help me to write the codinfor LED BLINKING

I want to write the coding for make the LED turn on if i press the button for 3 seconds and LED has to be turned off if o press the button for 5 seconds
can you help me with this controller
SDA -> PA0
SCL -> PA1
TIM2 -> PD7 ( this is the LED pin and i want to turn on this pin if is press the button for 3 seconds and 5 second means it ahs toturn off
ADC0 - > PD6
DAC0 -> PB11

It looks like the TD1204 uses UART and I2C to communicate - are you familiar with these protocols ?

You have to use Timer Interrupts. Which Compiler are you using ?

Is GGC Compiler a free compiler ? If yes, provide the download link for the Compiler. I will see if I can write a code for you. What IDE are you using to write the code ?

Should I install the 500+ MB software in the TD_RF_Module_SDK Zip file ?

Hello everyone am trying to turn on the LED by using the timer and button interrupt function, my aim of the program is, if i press the button for 3secthen LED turn and also the LED will be turned off by pressing the button for 5 sec ,but for this program i am not getting the output please rectify the errors and i would appreciate your suggestions (efm32g210f128 is the controller)
