I see... But the problem here is that the mentioned reset signal is probably a signal entering the component. This design would require a physical reset to be performed a startup, this is not automatic, do I understand correctly?
This is just an example. In the if statement part I had another statement that sets the counter variable, depending on the input signal. That did not work as well. How else can I create a 1 time execution situation?
You are right, but the thing is to make the input being read only once. Please take a look at this MWE:
--! Debounce hysteresis mechanism implementation
architecture arch_debounce of entity_debounce is
begin
process_debounce : process(clk)
variable test : bolean := false;
begin...
Hello, thank you for answer.
I tried doing just that- it did not help as well. I think in my situation (MachXO2 from Lattice) it is somewhat not possible to initialize the values this way. For example, when I created a separate bolean variable that is initialy false, and then in the behavioral...
Hello there,
I am designing a simple debounce mechanism in VHDL. I have the following problem. An internal counter (a variable) should be initially set to 0 or some value (ie. 100), depending on either the input is high or low at power up. I have no idea how to implement this. Is it even...
Thank you for answer,
That is something I was exacly wondering about, and even thought of it. I started doubting it, because the impedance I obtained from AppCad differed a lot from 50R when used parameters from the datasheet.
Hello there,
I have a question regarding calculating track width and gaps on the side for 4 layer PCB board, in order to maintain 50 ohm impedance for it. The term I have come across for calling this is "Coplanar waveguide". My problem is, that I need to calculate the widths for 4 layer PCB...
I am currently working on a device in which I need to implement internet connection. For that I intend to use a GSM module, for example this one: SIM5320. This is a 3G module. I have been reading about 3G vs LTE power consumption comparison (this is a good one: Comparing LTE and 3G Energy...
Thank you for the answer.
But before I jump into scripting and all, I need to figue out how to do basic tasts fast ie. Schematics, schematic DRC, PCB, PCB DRC and rules, component creation (Also with 3D steps if thats possible). Would there be any specific source you would advice me?
Hello there,
I am a long time Altium Designer user. Now I have to swap to Eagle for various reasons... I was looking for an advice on getting the most complete step by step guide on the usage of this software. I know that there are a lot of tutorials over the internet, but non of them is "full"...
I can post the code, it is not a problem. The thing is some of the commands work, so I am assuming the code works and I am doing something wrong with the configuration.
This is the function that should do the initialization of the chip communication:
/*
* @brief Final initialization...
I use my own code. I have only found the topic with your code and verified that I do everything correctly.
In my situation the SST26VF032B chip doesnt output anything on MISO line after asking him for status register etc. He only answers for identification commands.
The topic is about something else really, I just wanted to point out that the configuration is alright. My problem is that The only instructions that work for me are the Identification instructions. I cannot read status register, config register or block protection register. I think I tried...
Hello there,
I am writing a library at the moment to interface my STM32 mcu with SST26VF032B memory. I have a problem that I cannot solve for over 2 days now...
I am talking to the chip using regular SPI, not quad SPI. I am able to read JEDEC-ID as well as RDSR register. This ensures me in the...
