QUESTION
I'm trying to send byte array data from my computer to my Rpi and I have to use Byte Arrays for the task. As seen below in the first code line, which is the code in my private computer, I create the byte array and send it using ttyUSB0. I also decoded the same packet in my computer which gives the expected result. The expected answer is given in the image below. In my RPi,I use ser.read to read the lines I send but as seen at the last image, the entire package changes when I send the data over. I expect to see the same output I see on the first image when I replicate it on RPi.

QUESTION
I have 2 PLCs with serial port. one is mitsubishi Q00Jcpu mc protocol, another is omron hostlink protocol.
I tried to use python pyserial lib to write to the PLC and read response. But failed, I tried to use a serial tool to test and got nice response, serial tool success communicate with PLC, I read CIO address start 100 and size 2, it got 12345678, that is a true result.
my code :
...ANSWER
Answered 2022-Mar-19 at 02:45I figured it how, the return of serial.write is not the result. If need the response from device, should use read_until(), not sure weather this is a good way, please let me know if you have any suggestions. Anyway, the class i make, can read the omron PLC by giving different params, hope it can help someone.

The following code configures UART port.
...ANSWER
Answered 2022-Mar-18 at 10:55You seem to be another victim of UNIX/Linux versus Windows "newline"/"line feed" handling: UNIX/Linux uses single character, like 0A (line feed) or 0D (newline) for going to another line, while Windows uses a combination 0D0A, so most probably you have some program that converts your "I-believe-the-data-to-be-UNIX-like" into "Windows-like".
That might go far: I had the situation where UNIX files were sent to a Windows computer, and the user was using a Windows file viewer to see the content of the files, and it was the file viewer itself which was doing that conversion. Therefore I advise you to check all intermediate programs.

I am trying to establish a secure channel SCP02 with a smart card using python. My smartcard is connected to the terminal using a serial port and I use pySerial to send APDUs.
I send commands SELECT ISD, INITIALIZE UPDATE correctly, and next I try to do EXTERNAL AUTHENTICATE as the python code below:
ANSWER
Answered 2022-Jan-10 at 10:45You can use the working Test Vectors from the GlobalPlatform library and test if your executed crypto logic is really working. It could also be that your card is using some key derivation scheme, i.e. the keys you are using cannot be used directly.
QUESTION
I'm currently reading in data via a SerialPort connection in an asynchronous Task in a console application that will theoretically run forever (always picking up new serial data as it comes in).
I have a separate Task that is responsible for pulling that serial data out of a HashSet type that gets populated from my "producer" task above and then it makes an API request with it. Since the "producer" will run forever, I need the "consumer" task to run forever as well to process it.
Here's a contrived example:

I currently have a ASA Job that is streaming to an eventhub. From what I understand it may combine events from my query into batches for throughput reasons. However, when I check my output eventhub using service bus explorer, my events are not kept in a list like this:
...ANSWER
Answered 2022-Feb-18 at 22:41The setting you are looking for is Format in the EH output configration. You should switch it from line separated to array.
Pasting the doc here:
Format : Applicable only for JSON serialization. Line separated specifies that the output is formatted by having each JSON object separated by a new line. If you select Line separated, the JSON is read one object at a time. The whole content by itself would not be a valid JSON. Array specifies that the output is formatted as an array of JSON objects.
This is line separated:
QUESTION
I am first time using function pointers and ran into a weird problem. I am writing a code for STM32G4xx. The main idea is to transmit and receive data through LPUART. I have implemented simple FSM to handle TX and RX. LPUART configured in DMA interrupt mode. I have typedef the function pointer and declared the three function pointer variables (ISR handles) in main.h file as follow:
...ANSWER
Answered 2022-Feb-17 at 07:53As per @Lundin's suggestion, I have put a watchpoint on lpuart_dma_rx_tc_isr_clback function pointer variable. It exposed the out of index bug in my code. The bug is inside while loop in main.c.
QUESTION
I have a JS project where I manually define type declaration files in a separate directory. Previously I was using typedoc v0.19.2 and it generated documentation beautifully, using this typedoc config:
...ANSWER
Answered 2022-Jan-28 at 03:32I solved this issue using a typedoc plugin lib made specifically for this purpose, typedoc-plugin-not-exported. This flawlessly addresses this exact problem. Exposing types on the global scope isn't technically exporting them, and so the updated version of typedoc (I'm thinking >=0.20.0) won't include them. This plugin library fixes that.
