  1. MSP432P4111: What do we know about it so far?

    Something is out: http://www.ti.com/product/msp432e401y http://www.ti.com/product/msp432e411y They don't have exactly the expected part numbers, though. Both have 1024 kB Flash and 256 kB RAM and 120 MHz clock. Launchpad: http://www.ti.com/tool/msp-exp432e401y Strangely the 432P4111 launchpad http://www.ti.com/tool/MSP-EXP432P4111 seems tp be active now, too but the MCU is not available?
  2. Hi All First, I would like to thank @Rei Vilo for providing the Library for the Kentec (BOOSTXL-k350qvg) library with Energia. I copied the code out of https://www.youtube.com/watch?v=XyeUpk6P4kA (as I didn't find the powerpoint or pdf) and got it to work with an MSP430F5529 launchpad. (Energia 18, Windows as the Mac version doesn't work atm). Then I compiled the same code on a MSP432P401R launchpad and it runs a lot slower than on the F5529 (I assume this is a known issue, due to slow SPI speed ( https://github.com/energia/msp432-core/issues/27 ) but also doesn't look the same, the fonts are "skinnier on the MSP432. This discrepancy, I cannot explain. Another question: If I want to write a changing variable, in this case simply the x-coordinate of the touch to the screen, how do I locally clear the screen without redrawing everything (or if I want to make a bar graph that represents eg a changing value of a sensor? Do I always draw a black rectangle, then the bar/text etc? or is there a simpler way that is not immediately obvious to me now? Next step: I have to learn more about state machines to switch screens (settings), do stuff there, come back to main without the program getting into badly readable territory. Thank you very much for your help. //First steps with the Kentec Display #include "SPI.h" #include "Screen_K35_SPI.h" Screen_K35_SPI myScreen; uint16_t colours[6]; uint16_t x; uint16_t y; uint16_t z; uint8_t initFlag; void setup() { Serial.begin(9600); Serial.println(); Serial.println("hello"); Serial.println(); pinMode(RED_LED, OUTPUT); myScreen.begin(); myScreen.clear(); colours[0] = myScreen.calculateColour(255, 0, 0); colours[1] = myScreen.calculateColour(0, 255, 0); colours[2] = myScreen.calculateColour(0, 0, 255); colours[3] = myScreen.calculateColour(255, 255, 255); colours[4] = myScreen.calculateColour(255, 255, 0); colours[5] = myScreen.calculateColour(0, 0, 0); x = 0; y = 0; z = 0; myScreen.setPenSolid(true); myScreen.setFontSolid(false); myScreen.setFontSize(2); initFlag = 1; } void loop() { if (initFlag) { drawHomeScreen(); initFlag = 0; } if (myScreen.isTouch() > 0) { myScreen.getTouch(x, y, z); myScreen.gText(10, 10, btoa(x, 8), colours[3]); Serial.print(x); Serial.print(" "); Serial.print(y); Serial.print(" "); Serial.println(z); } if (z > 100) { if ((x < 160 && x > 0) && (y < 240 && y > 100)) { digitalWrite(RED_LED, HIGH); } else if ((x < 320 && x > 160) && (y > 100 && y < 240)) { digitalWrite(RED_LED, LOW); } else if ((x < 320 && x > 160) && (y > 0 && y < 100)) { drawSettingsScreen(); } } } void drawHomeScreen() { myScreen.clear(); myScreen.gText(30, 50, "TOUCH LCD DEMO", colours[4]); myScreen.rectangle(0, 100, 160, 239, colours[1]); myScreen.gText(50, 180, "ON", colours[0]); myScreen.rectangle(160, 100, 319, 239, colours[0]); myScreen.gText(235, 180, "OFF", colours[1]); myScreen.rectangle(160, 0, 319, 100, colours[2]); myScreen.gText(180, 50, "SETTINGS", colours[3]); } void drawSettingsScreen() { myScreen.clear(); myScreen.gText(10, 10, "TOUCH LCD DEMO", colours[0]); myScreen.gText(10, 30, "TOUCH LCD DEMO", colours[1]); myScreen.gText(10, 50, "TOUCH LCD DEMO", colours[2]); myScreen.gText(10, 70, "TOUCH LCD DEMO", colours[3]); myScreen.gText(10, 90, "TOUCH LCD DEMO", colours[4]); }
  3. Kentec Library (BOOSTXL-K350QVG)

    Hi @dubnet Thank you very much for your answer, I think this issue was for ccs. With ccs6 there was a slow TI GraphicsLib and they sped it up significantly for ccs v7 but I am not sure that one can just drop that into energia and be done with it. I did run the CCSv7 Demo on the MSP432 and it was FAST. (I am not ready for jumping over to the world of direct register manipulation tho... Energia is a good compromise for me in order to get ahead with my hobby projects...)

  7. TM4C I2C usage

    Hi, is that also possible with SPI in case there are several SPI interfaces? (One interface at a time means one per sketch or the first interface, then the second, then the first again in the same sketch?) Thank you very much
  8. Well, I tried ordering two of the boards and a couple small tx modules. Luckily they sent me a mail asking if I accepted their shipping charge of 76.81 USD. (for a total of 31 USD of components) Which feels outrageous and so I politely declined... I chose "cheapest international shipping method", so for living out of the US it's simply out of any range of justification for a hobby purchase.

    Hi @@zeke in my (limited) opinion, their work is good. Here's a board (the gerbers came from an eevblog member,[1] not mine) I had made privately: I had some made, the one I soldered the components on works perfectly. Of the ones from work I don't have any pictures obviously, they were only for a small project with a few components. The finish there was ENIG, which also turned out really well.

  13. One Wire Controller booster

    Hi Zeke, I was using http://www.pcbway.com/ at work and for a private project or two. At work we paid for fast shipping on some small simple boards that we needed quickly, the boards got here in less than a work week and looked good (and performed well). Otherwise you can check on http://www.pcbshopper.com/, they run comparisons on your size and time-requirements to help you find the optimal boardhouse. (I am unaffiliated with either company, only a customer and I used pcbshoppers website).
  14. Thank you very much for the info. I am in Switzerland, so I probably better forget about it... Unfortunately this board is not available with mouser, farnell, which ship to Switzerland for free if the order is for more than a certain amount.
  15. Adafruit ILI9341 port for Energia

    Hi @@artium Thank you very much for making this library available. I compiled it on a F5529 launchpad without issue (needed to adapt the pins slightly) I am trying to get it working on the msp432 now, however I am running into problems. First it mentions that min(,) is not defined, this is easily circumvented with two definesat the top of the sketch: https://github.com/energia/Energia/issues/815 Then I changed volatile RwReg with volatile int32_t in the h file where the SPI pin pointers are defined. Unfortunately, now the compiler tells me that digitalpintoport and associated functions are not defined. Do you or anyone have any hints? I'll upload the exact error message tonight, this is from memory...
  16. Did anyone order these boards by chance and could report on international shipping costs? I went through the whole order process and would have had to click confirm order without knowing the shipping costs... There are not estimates anywhere to be found unfortunately. (The boards are now up to 10 USD a piece...) Thank you very much

  18. Hi @Kelton Two quick questions: Did you restart energies after adding the libraries? It needs to read in the directories. Did you format your drive with the case sensitive hfs+ ? Then you'd need to match the spellings.

  21. Hi @@greeeg I downloaded cadstar and it installed design editor, library editor and migrate tool. If I transfer an example schematic to pcb I get a message that "the pcb design editor will work in unlicensed mode" and ... saving might not need possible. If I understand correctly, that would be included in cadstar express (or bigger) "The latest version of the CADSTAR Express free evaluation software for simple designs (limited to 50 components and 300 pins, is available to download at www.zuken.com/cadstar-express." The orcad offer also seems to be only for the schematic capture part (as well as only for our friends in the US ) Thank you very much for your answer!
  22. Hi Zeke, thank you very much for posting these offers. As I am only acquainted with Eagle I wanted to ask whether the featured Cadstar (or Orcad) packages are "just" schematic capture packages or whether one can prepare, route PCBs and export the Gerbers for production? Thank you very much!
  23. Hi, I am working on porting to energia and extending (by the ADS1258) an ADC-library (for the ADS1248 and ADS1256) that flydroid originally wrote for the teensy/arduino to energia on https://github.com/Flydroid/ADS12xx-Library/. My effort so far is under https://github.com/baettigp/ADS12xx-Library I got it running so far under an arduino uno, but have started running into limitations. The project will need more pins and serial speed (explaining my earlier question concerning the CDC mode to which I'll surely come back) and probably also RAM. I added in the #if !defined(ENERGIA) for the SPI begin and end transactions which are missing in energia. Then I tried compiling, but didn't get any reading on the serial port, so (still using the library) I wrote this minimal sketch: #include <SPI.h> #include "ads12xx.h" #define LED RED_LED const int START = 4;//8; const int CS = 8;//10; const int DRDY = 5;//2; const int RESET_PIN =3;// 9; ads12xx ADS(CS, START, DRDY); //initialize ADS as object of the ads12xx class void setup() { pinMode(LED, OUTPUT); digitalWrite(LED, HIGH); // turn the LED on (HIGH is the voltage level) delay(1000); // wait for a second digitalWrite(LED, LOW); // turn the LED off by making the voltage LOW delay(1000); // wait for a second Serial.begin(115200); while (!Serial) { } Serial.println("Serial online"); Serial.println("testing"); delay(1000); } void loop() { Serial.println("looping"); // put your main code here, to run repeatedly: } But it doesn't even blink the LED unless I comment out ads12xx ADS(CS, START, DRDY); I am not sure what goes wrong in the ADC initialization code for MSP that works with arduino: // ads12xx setup ads12xx::ads12xx(const int CS, const int START, const int DRDY) { pinMode(CS, OUTPUT); // set the slaveSelectPin as an output: digitalWrite(CS, HIGH); // CS HIGH = no select #ifdef ADS1248 pinMode(START, OUTPUT); // set START pin as Output digitalWrite(START, HIGH); // HIGH = Start Convert Continuously _START = START; #define spimodeX SPI_MODE1 #endif #ifdef ADS1256 #define spimodeX SPI_MODE1 #endif #ifdef ADS1258 pinMode(START, OUTPUT); // set START pin as Output digitalWrite(START, LOW); // HIGH = Start Convert Continuously // delayMicroseconds(1000000); delay(1000); digitalWrite(START, HIGH); // HIGH = Start Convert Continuously // delayMicroseconds(1000000); delay(1000); _START = START; #define spimodeX SPI_MODE3 #endif pinMode(DRDY, INPUT); // DRDY read _CS = CS; _DRDY = DRDY; // delayMicroseconds(500000); delay(1000); #if defined(ENERGIA) SPI.setBitOrder(MSBFIRST); SPI.setDataMode(spimodeX); SPI.setClockDivider(SPI_CLOCK_DIV8); #endif SPI.begin(); #if !defined(ENERGIA) attachInterrupt(0, _DRDY_Interuppt, FALLING); //Interrupt setup for DRDY detection #endif #if defined(ENERGIA) attachInterrupt(5, _DRDY_Interuppt, FALLING); //Interrupt setup for DRDY detection #endif // delayMicroseconds(500000); delay(1000); // interal VREF einschalten } If anyone has any idea on how to get it running, I'd be grateful. Once everything is working, I'll design a pcb and I'd rather stay with a TI microcontroller. (Not in the least as I'm trying to get up to speed with programming them more directly in CCS, but I have a four year old, so my progress on that front is only sporadic )

Today when I restarted looking at the problem after work, strangely everything worked with the F5529, I didn't change any code or upload the program, so it's a bit of a mystery as to why it wasn't working yesterday, maybe the adc was stuck in reset for some strange reason?
