because of the lack of proper debug support I jumped to http://www.nxp.com/products/microcontrollers-and-processors/arm-processors/kinetis-cortex-m-mcus/ea-series-automotive-m0-plus/nxp-freedom-development-platform-for-ultra-reliable-kinetis-ea-series-mcus:FRDM-KEAZ128 This comes ( if I...

Ability to debug is key to develop quality applications. I can't see how this is surpassed by other priority items.

What would be required to be able to single step through source code inside an Eclipse IDE using the latest Tinsy (3.6?) verion?

om http://www.stm32duino.com/viewtopic.php?f=41&t=522&start=90 by stevech Tue Feb 23, 2016 7:59 pm states: Maybe someone else knows of how to do real SWD debugging with free or cheap.

So does it allow code inline debugging full fletched with variable values etc etc?

any idea by when?

So you are getting there: good for you! Could you make a summary of all the settings and hyperterm used or telnet etc so that the essence or conclusion of this thread is captured for `human mankind`? I would also suggest that you try out to eliminate as many as possible of these weird pullup...

So can somebody show this "greenhorn" how to proper debug for $20? A video will do or a good tutorial or both...

Making your own C programs for the ESP8266 : https://youtu.be/pWo-ErpVZC4 making an image and download from scratch : getting all the utilities etc etc etc @Frank : excelent suggestion to Use Google :)

Wellll I have to admit that I have been in the same situation where ut was obvious that an I2C chip had to ad least ACK it's address on the bus but the component seem to be dead in the water: it turn out to be that I numbered the pins the wrong way ....... :mad:

okeee, got you. than flashing (as suggested before) a version that does work might be the best option for @onehorse and go grom there: make little increments in terms of adding new functionallity step by step. Sounds like the ESP can be completely standalone IOT board?

How do you hook up a virgin ESP at hardware level in order to get the above results Frank?

It is hard to justify $450 to proper debug a $20 Teensy board, when 99% (or more) of àll the code used ìs Open Source including Eclipse, RTOS, GCC etc etc. You can't develop a proper RTOS application without being able to properly debug it on the target IMHO

I am seriously considering hopping over to PIC32 just for one reason: I do want to have free limitless debugging facilities on also a FreeRTOS kernel on a PIC32 that has similar features. Main reason: I do not want to pay for getting a standard development feature that should be available in...

@onehorse Have you read http://www.instructables.com/id/Getting-Started-with-the-ESP8266-ESP-12/step3/Make-the-connections/ ? Seems like they have to ground a few unexpected pins in order to get it running and some more odd or unexpected things

get yourself a Buspirate to communicate to a serial TTL UART. Cheap and very simple configuration of port setting through a simple interactive menu instead of tinkering by building a new image install it run it change compile download etc : save you a great amount of time...

I think the AMS magnetic rotary encoders are briljant: there is one out there that will generate up to 500 pulses per revolution : that in combo with a SPI/I2C (not sure) using these pulses to be interrupts would make an excelent way of determing the angle and would significantly decrease...

So what kind of signal is coming out: you have a choice of a sinus and inverse sinus + cosinus and inverse cosinus ( so both balanced ) or a square wave output: is every sinus equals to one square wave??? What I would like to do is use a AS5311 which produces 4096 pulses per 2mm (so a...

which output form is provided: you can have sinus or even square wave signals: the last one would be ideal to be processed by a Teensy: Analog output? Not sure. do'm know the conversion rate is sufficient because it also depends on the speed the sensor is travelling

Interrupts short and simple: Good programming practices

In other words : more a 9600 baud serial cable replacer? :)

ESP8266 does not support incomming connections?

There is a forum forum on the ESP8266 with interesting topics

ESP8266 is a complete and self-contained Wi-Fi network solutions which cost around $5 A Guide To Using ESP8266 With TEENSY 3 suggestion per posting: provide short description besides a few letters acronym

I don't understand this part: Do you may be mean use the plugin a seperate Eclipse executable for Arduino/Teensy and an other Eclipse for ie Java? where to find this? Thanks

using printfs for debugging is compared to using breakpoints in your source code like well mmm : painting your entrance hall through a letter opening/plate in your front door ... because you will be able to see the stack trace and the variable's values when a breakpoint is hit

This is actually quite nifty: being able to use Teensy's JTAG pins so that your Eclipse IDE will allow you to single step through your source code on the target board itself and setting breakpoint etc: very handy when you try to debug a problem on a Teensy target. Hopefully Teensy 3.3 board with...

There is somebody that hacked the Teensy board to get access to the JTAG lines so that debugging from Eclipse on the target becomes possible: http://mcuoneclipse.com/2014/08/09/hacking-the-teensy-v3-1-for-swd-debugging/ Question would be: why not breaking out the JTAG pins on the Teensy board...

can you provide all you code?

Hi, I would like to capture frames or pictures/images from this nifty small powerfull and affordable CCTV camera which as far as I can find has at the minimum a Video (PAL/NTSC) output plus audio output. Is there may be another way to control the camera and fetch images through may be I2C or...

Is there a way to see what you have changed in your code to solve the overrun problems? BTW: I have used Track which is a code repository + ticket system + Wiki all integrated : right now this forum and some of different repositories is very hard to follow but I have no idea yet how to get the...

I would have a serious look at Eclipse because it is used in so many diff env: from Java, C etc etc and used even in professional environments so it would be another plus on your CV. And I guess that it is possible to have Teensy and Eclipse being able to control the actual application in...

Cool. Ever seen this? http://dangerousprototypes.com/docs/Bus_Pirate vèry handy for this serial stuff I am soooo green on Teensy : I bought the board 3 months ago and it is still in it's sealed package.. and I have to setup a development dev in (thank God) in Eclipse my favorite IDE so it...

Suggestion: could the ISR code for the reading and writing be combined into one piece of code that handles both the reading and writing by checking the control register (which will reflect a specific type of interrupt) from and to the UART so that independent of a burst on in this case the write...

This means that all the data in the UART's read FIFO can inserted into the read ring buffer in a single ISR to minimize interrupt overhead, and also several bytes can be written from the shared write ring buffer to the UART's write FIFO buffer within a single ISR call by the way: is the UART...

@defragster : I think it is better to start a brand new thread specific on ISR code design guide lines or best practices and use a UART as an example: it is far from trivial understanding the true context of an ISR in a RTOS and add that new thread to the general Wiki-like-tread

Hi All, It would be nice to have this in some sort of Wiki page or something to have an up to date list: no need to read every posting when a better suggestion is made on the intial post which is a briljant overview. Second suggestion is write something on best pratice. My first posting was on...

processing data from UART Hi All, I just registered so this my very first posting. I am a bit of a "greenhorn"... Although this is quite an old posting and it has been discussed in at least 2 threads, I do want to make a few remarks for those that read this thread. First of all, there is one...
