STM32 SPI communication with HAL

Asked 2021-Jun-11 at 11:58

I just started programming a STM32 and generated a code with CubeMX for an SPI communcation with a gyroscope (L3GD20) I have a problem with the HAL_SPI commands.

I first try to read the WHO_AM_I register which return a good response (0xD4) Then I tried to do the same with CTRL_REG1 register and it was still good by returning (0x07).

But if I try to get both of them one after the other, the HAL_SPI_Receive keeps sending the data of the first HAL_SPI_Transmit of the code... Tried to give it other buffers but still didn't work.

Here is the part of the code I'm intersted in :

Since HAL_SPI_Receive is already using HAL_SPI_TransmitReceive (github stm32f4 spi driver) to send dummy data to generate clock, you can use that fact and ditch the HAL_SPI_Transmit, and use the receive function like this:

FirebaseFirestore.getInstance() and app has stoped

Asked 2021-Jun-09 at 03:39

I run my Android app (based on Java), and it works. Next, I add to my app code:

FirebaseFirestore fdb = FirebaseFirestore.getInstance();

This code I got from the official Android site https://firebase.google.com/docs/firestore/quickstart

App runs, but next the running device shows the message "app has stopped".

I use a device simulator available in Android Studio.

It is my first Android app, and I can't understand what is going.

At the end of your log, just before the initial crash. there is a warning:

Default FirebaseApp failed to initialize because no default options were found. This usually means that com.google.gms:google-services was not applied to your gradle project.

simply adding com.google.gms:google-services should fix any issues you have, if you have issues, ensure your Gradle cache is cleared or run without the build cache --no-build-cache

QUESTION

Trait bound not satisfied in function argument

Asked 2021-Jun-05 at 14:56

I'm running into an issue with trait bounds and can't understand what I'm doing wrong. I'm working with the arduino-uno crate from avr-hal and I have a function that reads the ADC, implemented as follows:

...

ANSWER

Answered 2021-Jun-05 at 14:56

The compiler error says:

the trait bound &mut T: avr_hal_generic::embedded_hal::adc::Channel is not satisfied

Notice that the error is asking for &mut T to implement Channel, &mut T: Channel<...>, whereas your T has the bound T: Channel<...> — applying to T itself rather than &mut T. That's why the bound you've already written isn't helping.

Now, what's the right fix? If I look at the docs you linked, I can find the type of ::read. (Note: I copied the text from the docs to construct this snippet; I didn't read the source code.)

Cannot open source file avr/io.h (dependency of hal.h) with Visual Studio Code on windows 10

Asked 2021-Jun-05 at 07:00

I want to implement an embedded project using stm32F0 (arm-based) with VS Code. The project ran properly on other systems.

I Added C/C++ extension to visual studio
I installed a compiler for cortex-m0 arm: GNU Arm Embedded toolchain/gcc arm for windows.
Makefiles installed: binaries file + dependencies file
openOCD installed (open On Chip Debugger)
tasks.json (build instructions), c_cpp_properties.json (compiler path and IntelliSense settings) were created. I modified the Include path because my program includes header files that aren't in my workspace, and that is not in the standard library path.

Cannot open source file avr/io.h (dependency of hal.h)

You appear to be using ChibiOS whhich has a file hal.h which includes halconf.h which includes mcuconf.h. Clearly you appear to have an AVR port of ChibiOS where you need STM32 or ARM Cortex-M support.

But, how VS Code can find dependencies before compiling?

The same way as the compiler/pre-processor do, by having include paths configured, parsing the project files and accounting for any externally defined (command line) macros.

I also was wondering if I should add a path for main.cpp file and other C and CPP files in the configuration file of VS Code to solve these problems?

I believe it will parse project files in any case. It only needs to find the header files included in a source file to provide context for the parsing of the sourcefile.

For debugging, I don't see any debugger in the list, though I installed openOCD and add the path in the environment variable

That is an entirely different question - post a new question for that.

Using Rust crates for an STM32 microcontroller board

Asked 2021-May-29 at 19:34

I'm currently trying to learn Rust (for embedded specifically), coming from a background of C for embedded systems and Python. So far, I've been reading Rust Programming Language and Rust for Embedded, and read a few blog posts on the web.

I want my first project to be a simple "Blinky", where an LED blinks infinitely. I've got an STM32L152CDISCOVERY board with an STM32L152 chip in it (basically same as STM32L151), which is a Cortex M3.

Instead of implementing everything from scratch, I want to leverage existing crates and HALs. I've found two that seem promising: stm32l1 and stm32l1xx-hal. I've tried to read the documentation of each of them and also part of the source code, but I still can't figure out how to use them correctly.

Got a few questions about Rust and about the crates:

I see that stm32l1xx-hal has a dependency on stm32l1. Do I need to add both as a dependency in my Cargo.toml file? Or will that create problems related to ownership?
Is this the correct way to add them? Why is the second one added like that [dependencies.stm32l1]?

Answered 2021-May-29 at 19:32

stm32l1xx-hal already depends on stm32l1 as seen here. There's no need to import it twice. It is enough to add to Cargo.toml:

QUESTION

Spring WebClient does not read hypermedia links

Asked 2021-May-28 at 09:50

I am reading from an external API with hypermedia links and OAuth2 authentication using Spring's WebClient. When accessing the API the JSON data is correctly converted to model objects but the supplied HAL links are either omitted if the model object extends Spring HATEOAS RepresentationModel or give a NullPointerException when the model object extends EntityModel. I suspect a problem with the hypermediaWebClientCustomizer but was not able to solve it as of now.

I tried reading the JSON with a Traverson client in a testcase. That was basically working, if i replaced relative URIs with absolute URIs and the application/json header with a application/hal+json header. I would go on with Traverson but besides these two problems Traverson requires a RestTemplate (OAuth2RestTemplate in this case), which is no longer available in our Spring version.

Any ideas if there is a problem with the configuration or what else could go wrong?

QUESTION

Using EEPROM in STM32f10x

Asked 2021-May-27 at 04:32

I'm using STM32f103 and in my program, I need to save some bytes in the internal flash memory. But as far as I know, I have to erase a whole page to write in it, which will take time. This delay causes my display to blink. Can anybody help me to save my data without consuming so much time?

Here is a list that may help:

1- MCU: STM32f103

2- IDE: Keil vision

3- using HAL driver provided by STM32CubeMx

4- sample data for saving in Flash: {0x53, 0xa0, 0x01, 0x54}

In the link below, you can find the code that I'm using.

ANSWER

Answered 2021-May-23 at 10:47

The code you provide doesn't seem to be implemented well. It basically does 2 things each time you initiate a write operation:

Erase the page (this is the part that takes time)
Start form the given pointer, write until it hits a zero.

This is a very ineffective way of using the flash.

Probably the simplest and the most well-known way is to use the method described in ST's AN2594, although it has some limitations.

Still, at some point a page erase will be necessary regardless the method you use and there is no way to avoid some delay, unless your uC supports dual flash banks (STM32F103 don't have this feature). You need to plan the timing of flash writes and display refresh accordingly. If you need periodic writes to the flash, there is probably some high level error in your design.

In your callback to forEach() you use this. You think it refers to the component but it does not. You can easily see this if you log this to the console. Or you can use a debugger and set a breakpoint inside your callback.

You need to use an arrow function to correctly capture the value of this.
