    Store values inside µc

    sehr gute Antwort😊!!!!
  2. @REI VILO i think the RXD and TXD signal are inverted on the Pin map from MSP430G2XXX: http://www.energia.nu/pinmaps/msp-exp430g2/ For me on the launchpad MSP430G2553 TXD output from the chip is on pin P1_2, not P1_1.

    Using FRAM above 0x00010000

    "support has been added in Energia for the MSP430FR5994" but Serial1 is not working, and and even more unfortunate, the available I / O still does not support interrupt handling. I mentioned these problems since May 2018, Energia1.8.7E20 is available and the same problems are still unresolved. It is difficult to try to work with a chip that is very poorly supported by the ENERGIA teams. Sorry for this reminder, but please try to do something! I develloped a simple Lora gateway (Wifi+GSM/GPRS) from this launchpad and the results are good despite these difficulties of programming!!
  4. you can not use Lora library with the MSP430G2553. Ram is to small !!!!! only 512 bytes Arduino 2Kbytes SRAM
  5. I'm sorry but I do not know how to do it right. Can you do it. thank you very much
  6. My previous post February 14 2018: Hello all I use actually the MSP430FR5994 Launchpad. I can not output characters with Serial1 on the P6_0 TXD Output. I have debugged the driver and i think the "#define AUX_UART_MODULE_OFFSET 0x60" in \variants\MSP-EXP430FR5994LP\pins_energia.h must be changed to : #define AUX_UART_MODULE_OFFSET 0x20 With this change : I have debugged with a scope and P1_0 output as trigger the uart interrupt routine for Serial1 on EUSCI_A1 internal eUSCI , and all characters are transmitted, but nothing on P6_0 which is always High. has Serial1 been tested? it would be nice If I can get help !
  7. And for the Serial1 bug , I do not know how to do it (to open the request) Sorry
  8. Could you explain please why in pins_energia.h, there is two #define for uart 0 and 1 which are #define DEBUG_UART_MODULE_OFFSET 0x00 and #define AUX_UART_MODULE_OFFSET 0x60 but in msp430fr5994 documentation the base adress for uart 0 is 5C0h and for uart 1 base adress is 5E0h. the offset is 5E0-5C0 -> 20h not 60h in previous post i have explained the problem and i have received no response. I have tested the uart1 acces with 20h offset and for me this is the right offset to acces the Uart1. Can i be wrong !!!!! and for the I2C two pin 9-10 you have this remark: So I'm not sure that the file does not contain some errors!! Thank you for you precious help
  9. I have posted the following remarks in Mars2018: "I use actually the MSP430FR5994 Launchpad. I can not output characters with Serial1 on the P6_0 TXD Output. I have debugged the driver and i think the "#define AUX_UART_MODULE_OFFSET 0x60" in \variants\MSP-EXP430FR5994LP\pins_energia.h must be changed to : #define AUX_UART_MODULE_OFFSET 0x20 With this change : I have debugged with a scope and P1_0 output as trigger the uart interrupt routine for Serial1 on EUSCI_A1 internal eUSCI , and all characters are transmitted, but nothing on P6_0 which is always High. has Serial1 been tested?" For the function attachInterrupt(), all I/O pins can not call the attached interrupt routine.. You can read/write I/O but not attach interrupt routine, interrupt is not called! I think the file variants\MSP-EXP430FR5994LP\pins_energia.h has too many false declaration!! But i am not specialist on Energia structure. I use Energia to program launchpads, i can debug my program but not energia ide (the last version 1.6.10E18).
  10. Hello team Energia I already asked the question for the serial port, and I never had an answer. There is also one of the simplest primitives that does not work: attachInterrupt() To work around the problem, I used gpio.h and gpio.c. But I would prefer to use the Energia functions. Can someone now look into these two issues? Can we hope!!!!!!!!!!!!! thank you in advance

    MSP430FR5994 sram in boards.txt

    StefanSch from Energia team has resolved the problem and the Sram for user is 4kbytes. Thanks Stefan!!!!!
  12. You can use this library: -2-[Energia Library] Jaffl Just another FatFs library - MSP Energia Libraries - 43oh.URL

    Data logging

    Youn can mix Energia library : and msp430ware API from TI to have an mix to build the perfect data logger , first on Fram then on SD card once a day.

    LAUNCHPAD MSPFR5994

    Hello team Energia can anyone from the ENERGIA team look at the Serial1 serial issue? This card is a marvel and it is missing only this part to use it full. thank you in advance
  15. I tested your port on the new Launchpad MSPFR5994: This card already has an SD card mounted, and everything works perfectly. Thank you very much for your work
