When the SPI library is called from a library, compilation fails, even when SPI has been included in the main sketch.

The culprit seems to be the empty file SPI.h at ~/Library/Energia15/packages/energia/hardware/cc3200/1.0.2/libraries/AIR430BoostEuropeETSI/SPI.h.

Removing the file solves the issue.

The following sketch succeeds to compile against the CC3200 but fails against the CC3220SF.

Once issue #19 has been patched with the suggested solution, the SmartConfig.ino example fails to run properly.

The same example built in January 2017 runs fine. Has a regression bug been introduced since then?

Testing #6

CC3200 and CC3200 EMT appear the same.

Here's the issue. I am working on a project where I was asked to use CC3200 WIFI to create interference in a transmission where 2 nrf24l01 Transceivers are communicating with each other. Initially, I flashed the HTTP server program to the cc3200 using Uniflash and ccs. That didn't create any interference. Now I wish to send continuous data from my phone/laptop to CC3200 in order to create some rigid Interference.
Now I have two issues,

1. Initially, I want to test CC3200 with Energia sketches starting with the blink and other wifi examples.
   Now the problem is, my cc3200 is not responding to any of the sketches I am uploading through Energia. Every time, there is no problem with the compilation and upload, everything is functioning smoothly, but my cc3200 is not responding at all. I tried the blink and simple web server wifi sketches.
   Can anyone tell me how to make my cc3200 respond to the blink, other Energia sketches?

2. Does anybody know any sketch in the Energia examples which I can use to proceed with my particular case? (i.e., to send data from a client to cc3200 in order to create interference in the nrf24l01 transceivers communication)

P.S: I am a newbie, just started using CC3200 a week ago, lack of solid resources is eating up my brain. I hope you don't mind my silly issue.

Slave I²C is not implemented for CC3200.

The repository for the CC3220 boards package is available on the Energia IDE but the source code is missing from the GitHub Energia repository.

Once issue #19 has been patched with the suggested solution, the WiFiUdpNtpClient.ino example fails to get time.

WiFiUDP::parsePacket() exits at line 277.

    if (iRet <= 0) {
        return 0;

Any idea?

Currently, the CC3200 only features the upload to RAM.

Please add upload to Flash.

Updated boards.txt for MSP432 and MSP430 uses maximum_data_size

MSP-EXP432P401R.upload.maximum_data_size=65536
MSP-EXP430F5529LP.upload.maximum_data_size=8192

when Tiva C and CC3200 use maximum_ram_size

EK-LM4F120XL.upload.maximum_ram_size=32768

CC3200-LAUNCHXL.upload.maximum_ram_size=32768

When compiling the MultiBlink.ino against the CC1310 EMT and MSP432 EMT, compilation generates two files, MultiBlink_CC3200.ino.cpp and main.cpp.

The former concatenate all the different task into one file and the latter declares the tasks to the RTOS.

However, compiling the MultiBlink.ino against the CC3200 EMT does not generate the main.cpp.

Has the compilation procedure changed?

Hello, I'm new to this and I'm probably doing something wrong and that's why I'm here. I get this message in the title when i try to Verify the code and i cant fix it. I've seen other threads with different boards and how they fixed the problem. So i tried the same with CC3200 launchpad by changing the boards.txt file.

I changed the line:
CC3200-LAUNCHXL.build.board=CC3200-LAUNCHXL
to this:
CC3200-LAUNCHXL.build.board=CC3200_LAUNCHXL

I also added this:
{"name": "CC3200_LAUNCHXL"},
to package_index(JSON File)

None of this didn't fix the problem, I still get the same message. Anything else i can do?

For CC3200, CC3200-EMT and CC3220-EMT, implement OTA upload.

This would ease the upload process.

ESP8266 has already implemented this process as a library, ArduinoOTA, to be found at https://github.com/esp8266/Arduino/tree/master/libraries/ArduinoOTA

I have written a small Energia sketch to switch back and forth between AP and STA.
Switching works initially, but always ends up failing eventually after switching a seemingly random number of times.

I've run this test multiple times and recorded the number of times it was able to switch before getting stuck:
57, 128, 62, 75, 104, 46, 30, 26, 9, 47, 52, 51.
It always seems to eventually get stuck in the switch from AP to STA, but never when switching from STA back to AP.

I am using the latest commit of the WiFi library from this repo.

I've found an interesting solution for my latest project Pervasive Reporting on the CC3200.

The e-paper display requires to have two frame buffers on RAM, but using two arrays of 9472 bytes raised an error while compiling.

~/Library/Energia15/packages/energia/tools/arm-none-eabi-gcc/4.8.4-20140725/bin/../lib/gcc/arm-none-eabi/4.8.4/../../../../arm-none-eabi/bin/ld: ~/Library/Developer/Xcode/DerivedData/eX-Check-Display-dkzssdmfeebnduggodwhukhifkst/Build/Products/Debug/embeddedcomputing.elf section '.heap' will not fit in region 'SRAM'
~/Library/Energia15/packages/energia/tools/arm-none-eabi-gcc/4.8.4-20140725/bin/../lib/gcc/arm-none-eabi/4.8.4/../../../../arm-none-eabi/bin/ld: region 'SRAM' overflowed by 12376 bytes

I was surprised, since the CC3200 features 512 kB 256 kB of RAM, but Energia is mum about how they are allocated.

According to this E2E post, editing the cc3200.ld link script solved the issue.

I just changed HEAP_SIZE = 0x00010000; for HEAP_SIZE = 0x0000C000; as suggested, and everything built and ran fine now.

Is there something similar to the solution we're using for FRAM (energia/msp430-lg-core#31)?

#define PLACE_IN_FRAM __attribute__((section(".text")))

Please create a specific CC3200 EMT repository for issue tracking.

Same as energia/msp432r-core#17 but for CC3200 non-EMT.
