  1. Hello, I'm working on a warningsytem with ultrasonic parking sensors.(https://www.dometic.com/nl-be/be/producten/veiligheid-en-beveiliging/voertuigaccessoires/parkeerhulpen/dometic-magicwatch-mwe-7106f-_-63981)) In some cases there are 5 sensors needed but most times just 4 sensors. The system has to have an on/off mode with the use of a pushbotton. There wil also be an extra sensor at the input (analog or digital, not certain yet) witch determines the field that has to be monitored. In the case of digital, there are going te be 1 or 2 sensors. At the output there are a Led (to signal broken or dirty sensor), a buzzer that gives different beeps depending on the distance to the object. To stop the moving of the vehicle, I also need a breakcontact so the output of the control has to be a relay. Total: Input: 4/5 ultrasonic sensors, pushbotton,1 analog sensor or 1/2 digital sensors. Output: Led, buzzer, relay I want to make 4 differrent zones. Each zone has it's own beeping sound and the last zone (closed to the object) also has to switch the relay. after 2 seconds, the relay has to switch again and then the driver has again 2 seconds to move the vehicle. If that doesn't happen, the relay has to switch again. When the extra sensor signals '1' or a certain analog signal, then the zones themself stay the same. but they al move 20cm further from the vehicle. I'm using the PGA460-F5529-BNDL, it contains the MSP-EXP430F5529LP and the BOOSTXL-PGA460. The programming of the MSP430 isn't going to bad but I can seem to make the sensor work with the BOOSTXL. The sensors are Lin connected and n expert told me that I can connect them with One-Wire UART. It doesn't seem to connect but maybe I'm using the wrong pins or something. Then there's also the problem that I have to communicate with every sensor individualy. The expert said that it's possible if every sensor has it own code, then the sensor knows if the signal is for him or not. They are namely all connected with one wire. Does somebody had experience with this? It would be great if someone could tel me how I should place everything but an example program would be absolutely awesome! Sorry for my terrible english, I hope it's a bit understandable. Thanks
  2. Hi, I am using the MSP-EXP430F5529 launchpad to read values from the ADC pin. However, i read garbage values when using a baudrate of 250,000. Why is that so? It works perfectly fine with baudrate of 115,200 and anything more than that does not work. Please help!! Regards
  3. Output Pins Don't Work

    Hi, I'm running Energia on Windows 7 x64. My Launch Pad model is the MSP-EXP430F5529LP (25Hz) My board's green LED will light up when connecting to the computer, the red LED will flash while compiling and all onboard LEDs and buttons function when programed. However, whenever I try to program output pins and connect the output in question to ground, I get no current out. I have plenty of experience with Arduino and all programs I write for the Launch Pad work for Arduino. The GND, 5V and 3.3V pins on the LaunchPad all work fine. I have also used a number of sample programs, all to no avail. Here is a schematic sheet for my model. http://energia.nu/img/LaunchPadMSP430F5529.jpg Here is a quick program that I have written to demonstrate one way that I have been testing it. const int led = 19; // LED is hooked to P2.0 aka 19 with at 220 Ohm resistor and then connected to ground. void setup() { pinMode(led, OUTPUT); } void loop() { digitalWrite(led, HIGH); //LED should turn on and quickly flash off and on again delay(1000); //I know for sure that the LED is not broken because I digitalWrite(led, LOW); // repeatedly test it with my Arduino between compiling delay(500); }
  4. I found out from this post that there are 14 PWM outputs possible on the MSP430F5529 microcontroller, and 10 PWM outputs possible on the MSP430F5529 Launchpad. How many are possible when using Energia? I think it is less, but I can't tell from the .h file. I will be using a custom BoosterPack so it doesn't have to stick to that standard. Thanks, Ben
  5. According to the docs, it takes ~100 microseconds: http://energia.nu/AnalogRead.html. I measured this and it seems to be almost exactly 100 microseconds. Why does it take so long? This limits me to 10kHz sample speed. By the way, how fast have any of you guys sampled on the ADC12 of F5529?
  6. Hello I'm not sure where to post, so I do it here, please feel free to give me the correct topic to go to, Sorry !-) I am new to MSP-EXP430F5529LP and Energia. I tried to install Energia 0101E0010 following the getting started webpage (http://www.energia.nu/Guide_MacOSX.html). Everything looks correct but Serial Port is grey, no ways to get it... So, I tried to install 0101E0009. Here, Serial ports are looking correct (although I have 2 potential candidate ports that I have seen nowhere in the topics on this forum: /dev/cu.Z530i-SerialPort-1 or /dev/cu.Z530i-Dial-upNetworking-2, or the corresponding ones with tty instead of cu), but the MSP-EXP430F5529LP is not on the list of available boards... Could anyone help? Thanks a lot Pablo
