[Energia Library] Jaffl: Just another FatFs library
jcR replied to geometrikal's topic in MSP Energia Libraries
Hi Geometrikal, Hi TL The portage works perfectly, it is only necessary to put the good chip select for the Launchpad as well as to specify the good bus SPI in the file Jaffl.cpp in the routine SPI_INIT. For the applications which I use I tested at the same time the competition between the SPI bus (0) which manages the SD card and the SPI bus (1) which manages another device. I enclose all the necessary sources to test on a Launchpad MSP430FR5994. For my work I use Visual Studio 2019 with the Visual Micro plugin. I can compile for Arduino (Arduino,ESP8266,ESP32,ST) and Energia fa -
I still do not understand why corrections have still not been made for this chip. As I needed these corrections, I had to do them myself although I am not a specialist on this subject. So I modified the necessary files to have access to all the pins of the MSP430FR5994, even those which are not cabled on the Launchpad, in order to be able to use them on my own cards. I enclose the modified files as well as the positions in the folders, to help the users facing the same problems as me. It would be desirable for the Energia team to finally address these issues and inclu

sehr gute Antwort😊!!!!

@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.

"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!

Using SPI and LoRa Libraries in Energia for MSP430G2553
jcR replied to LoRaWAN's topic in Energia - MSP
you can not use Lora library with the MSP430G2553. Ram is to small !!!!! only 512 bytes Arduino 2Kbytes SRAM -
I'm sorry but I do not know how to do it right. Can you do it. thank you very much

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

And for the Serial1 bug , I do not know how to do it (to open the request) Sorry

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

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.

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

StefanSch from Energia team has resolved the problem and the Sram for user is 4kbytes. Thanks Stefan!!!!!
