QUESTION
I'm trying to write an I2C Slave and test it in isolation.
I have a simulation that should be pulling SDA low when write_ack is high (Also highlighted by the red dots). However, you can see that SDA remains the same.
Part of me thinks it's to do with the way I'm testing with the force methods and the delays.
Any help appreciated.
I have found the keyword release which seems to help.
Code below & EDA Playground is here: https://edaplayground.com/x/6snM
...ANSWER
Answered 2021-May-17 at 17:20Instead of using force, a more conventional approach is to add a tristate buffer to the testbench, just like you have in the design.
For SDA, create a buffer control signal (drive_sda) and a testbench data signal (sda_tb). Use a task to drive a byte and wait for the ACK.
Since SCL is not an inout, there is no need for a pullup, and it can be directly driven by clk.
QUESTION
Could somebody help me with this problem, I'm trying to retrieve how much data has been send with webrtc. But I can't get my head around these promises.
I need to iterate throught he list of senders, but for each sender I need to await the promise before I can continue with the next sender.
...ANSWER
Answered 2020-May-23 at 13:26As you say, you can't use the results until all the promises are settled. You can use Promise.all to wait for them, see *** comments:
QUESTION
I am currently trying to get a simple multi-GPU program running with CUDA. What it basically does is it copies a large array with some dummy data in chunks to the GPUs, which do some math, and then copy the resulting array back.
I dont get any errors in the output of VS2017, but some error messages I have set up show me that while trying to copy either H2D or D2H. It tells me that a cudaErrorInvalidValue is occuring. Also, when using the cudaFree(); function, i get a cudaErrorInvalidDevicePointer error.
The output of the program, the result, is completely wrong. The kernel is, for testing purposes, only setting every value of the output array to a value of 50. The result is a relatively large negative number, always the same no matter what the kernel does.
I have already tried to use a pointer that is not part of a struct, but is defined right before the cudaMalloc, where it is used first. That did not change anything.
This is the function that runs the Kernel:
...ANSWER
Answered 2019-May-29 at 16:17The first problem has nothing to do with CUDA, actually. When you pass a struct by-value to a function in C or C++, a copy of that struct is made for use by the function. Modifications to that struct in the function have no effect on the original struct in the calling environment. This is affecting you in your memAllocation function:

i have csv file that i need to read with php.I used 2 method but there is problem in theme.
methode i used are: 1- file_get_contents 2-fgetcsv let explaine about csv file. the problem about the file is the fields contain comma that is used for delimiter and its bothering. the first methode is fast but commas in the fiels make it work incorrectly like number seperator 14,200 . i fixed it withe a function named fixed number. but there is still random text that contain comma and doesnt follow any rule that i can fix them the second method for large csv is very slow and i cant get out put to see that its working the code for first methode is like:
...ANSWER
Answered 2019-Jan-01 at 19:32So I waited the minute to download the file, grabbed the first 5 records, and used a copy/paste of the fgetcsv example in the PHP manual.
First 5 records - https://termbin.com/23ti - saved as "sm_file.csv"

I'm trying to write integer data into CSV file in every iteration, this is my code and I've got this error message
Error: using dlmwrite (line 112) Invalid attribute tag:1
My code:
...ANSWER
Answered 2018-Dec-28 at 04:26You are using dlmwrite incorrectly. You have to remove dataCounter and dataPredictionCounter because those aren't arguments to dmlwrite. This will be very slow. You can put everything into an array first and then write the array to the file with csvwrite.
QUESTION
I have a header and data which I need to represent in one Byte Array. And I have a particular format for packing the header in a Byte Array and also a different format to pack the data in a Byte Array. After I have these two, I need to make one final Byte Array out of it.
Below is the layout which is how defined in C++ and accordingly I have to do in Java.
ANSWER
Answered 2017-Jan-20 at 00:45Another way of doing it would be via a DataOutputStream around a ByteArrayOutputStream, but you should concentrate your performance tuning around the places it's needed, and this isn't one of them. Efficiency isn't any kind of an issue here. The network I/O will dominate by orders of magnitude.
Another reason to use a ByteArrayOutputStream is that you don't have to guess the buffer size in advance: it will grow as necessary.
To keep it thread-safe, use only local variables.

I followed this solution for my project : How to create bitmap from Surface (SharpDX)
I don't have enough reputation to comment so I'm opening a new question here.
My project is basically in Direct 2D, I have a Surface buffer, a swapchain. I want to put my buffer into a datastream and reads it's value to put it into a bitmap and save it on disk ( like a screen capture), but my code won't work since all the bytes values are 0 (which is black) and this doesn't make sense since my image is fully white with a bit of blue.
Here is my code :

Answered 2017-Jul-05 at 15:17I answered in a comment but formatting is horrible so apologies!
https://gamedev.stackexchange.com/a/112978/29920 This looks promising but as you said in reply to mine, this was some time ago and I'm pulling this out of thin air, if it doesn't work either someone with more current knowledge will have to answer or I'll have to grab some source code and try myself.
