  1. I have custom board of TM4C1292NCPDT. I want to upload/dump Energia sketch on it. Could anyone explain detail procedure in steps to do that ? Thanks.
  2. Hello guys, I am using the tm4c123 and I need to use the pins PD_4 and PD_5 in my custom board... but these pins have no definition in the Energia... I would like to use this pins as inputs (digitalRead function) I had the same problem with the PQ_4 on the TM4C129 Could I make some #define in the pins_energia.h to use this pins??? Regards
  3. Hello, I am new to this forum. I apologize for my username! It seemed no usernames I typed were accepted no matter how I varied and interspersed numbers. Well I typed in numbers and hit return and there I was registered with that username. Anyway, I just rcvd my Tiva EK-TM4C1294XL Launchpad yesterday. The ti.exosite.com demo worked just fine over ethernet. Then I downloaded energia. Long story made short is I seem to be getting a timeout when uploading any example. The upload seems to take a long time then gives me the error "an error occurred when uploading the sketch" I reinstalled the drivers from the Stellaris zip file. The drivers went from version 2.0.9270.0 (which installed automatically) to 2.0.7920.0 from the zip file download. This made no difference. I unplugged the ethernet and tried resetting the board...no difference. My board type shows properly "Launchpad (TIVA C) w/TM4C129 (120MHz)" w COM4 on my computer. Dev Mngr shows all three drivers installed properly. All jumpers seem to be set properly. So I am looking forward to programming on this device. Looks like I will punt and re-download energia again. Perhaps try a new USB cable as suggested. Any ideas will be appreciated. The verbose output file is attached. Thank you for any help. I look forward to participating on this forum as I gain experience. Energia upload error log.txt
  4. It would be really awesome for my project if I could update code over Ethernet, instead of USB for my Tiva C connected. I've tried the latest version of the LM Flash Utility (Build 1613) and cannot seem to connect to the Tiva C over Ethernet with the utility. I have a MAC and IP set on my board using the Energia Ethernet UDP library and can verify them with a ping and look at my laptop's ARP table, but I am unsure if this is enough to satisfy the needs of the LM Flash Utility. I was hoping that the functionality would be supported "behind the scenes" in Energia, but that does not seem to be the case. Is there a TI TivaWare/StarterWare function that can be easily called to gain this functionality? Has anyone here had any luck trying to program the Tiva C connected over Ethernet?
  5. I am using this current sensor in my project. The Vout pin needs to be connected to the ADC. The best way to do this is to connect it to some analog pin and tie that analog pin to ADC through the code. Anything else? Can you refer to a sample code for this?
  6. I am using TM4C129 Launchpad launchpad and trying to connect XBee Series 2 (S2C) through UART. Looking into the pinout of TM4C129, I am connecting like below XBee TX <---> RX (UART0) XBee RX <---> TX (UART0) XBee 3.3V <---> pin#41 XBee GND <---> pin#62 I use below code on the LaunchPad at Energia void setup() { Serial.begin(9600); //pinMode(13, OUTPUT); } void loop() { Serial.println('H'); delay(1000); Serial.println('L'); delay(1000); } And the below python code runs on my Mac as a coordinator #!/usr/bin/python import serial ser = serial.Serial('/dev/tty.usbserial-A104IC2U', 9600) while True: incoming = ser.readline().strip() print '%s' % incoming But it doesn't work. FYI, this code worked on Arduino. Has anyone tried this before? Any suggestion? Am I missing some connection? jumper settings? Anything on the code?
  7. The latest official version of Energia (energia-0101E0012) does not define TEMPSENSOR for the TM4C1294 MCU. The suggested solution discussed at https://github.com/energia/Energia/pull/364# does not work for me. The function call to analogRead(TEMPSENSOR) is hanging the program. I have found a quick and simply solution for the problem, so anyone can use it until a better solution will be found. 1. Add this line to file pins_energia.h in folder Energia/hardware/lm4f/variants/launchpad_129 #define TEMPSENSOR PB_1 //Will be translated to ADC_CTL_TS 2. In the same file modify the following line (in the definition of array digital_pin_to_analog_in[], near to end of file): NOT_ON_ADC, // 95 - PB_1 unrouted simply replace it by ADC_CTL_TS, // 95 - PB_1 unrouted These modifications define the TEMPSENSOR symbol and will select the internal temperature sensor when readAnalog(TEMPSENSOR) is called. Here is a simple example sketch: uint32_t val; float temp; void setup() { Serial.begin(9600); } void loop() { delay(1000); val = analogRead(TEMPSENSOR); Serial.print("adc:"); //raw ADC data Serial.print(val); temp = 147.5 - 75*3.3*val/4096; //temperature in Celsius Serial.print(" temp:"); Serial.println(temp,1); } Good luck!
