    How to get rid of these weird charcters?

    Hello! Is it solved now? For your information, the characters you see are not that weird to me, they are simply Japanese. The character LCDs usually have means to reconfigure the character set, so I don't think it's a matter of wrong atoi or anything else, it's just a matter of LCD...

    STM32 VCom port problem

    Hello! I have tried to make a VCom port experiment using a nucleo 144 board (with STM32F767 chip). I'm working on Ubuntu 20.10 and STM32CubeIDE, version 1.6.1. I have looked at the following link, and although it's not the exact same development environment, I suppose it's similar. I like...

    Using systick. STM32F769, STM32IDE

    Hello again! Sorry for the mess, I found what's wrong. In fact, I have configured the Cube to handle an SD card. But the error handling of the SD card is pretty bad, there is only an infinite loop. In my case, as no card was inserted, I had a card initialization failure, therefore an infinite...

    Using systick. STM32F769, STM32IDE

    Hello! I have the following problem: A few years ago, I was using CubeMX to configure my programs and it worked fine. Basically what I always do is setup a systick of 1 ms, and build the whole program on that time grid. Now in the latest version of Cube MX, which is now integrated into...

    Problem using Max 10's memory blocs

    Hello! I don't use any clock enable, so I can't understand the error message. I noticed that some memory (altsyncram) is generated, but the complexity of that file is beyond my newbie understanding. And I'm not sure of what is a global signal. Is it one that is in the parameter list of the top...

    Problem using Max 10's memory blocs

    Hello! I am trying to use the dual port sunchronous ROM described in the document above. I have made the proper setting as indicated above (assignments -> device, etc..). I used the code example 13-31. Analyzis and synthesis goes fine, but I get the following error in the fitter process. I'm...

    Problem using Max 10's memory blocs

    Hello! Thanks for your reply! And thanks for the link. It confirms that it's basically what I was more or less doing before trying to instantiate the memory IP. Beside this what I did was working but I didn't manage to get the IP data. That said, I found some possible explanation of why it...

    Problem using Max 10's memory blocs

    Hello! Thanks for your help. 2 news, one bad, one good. The bad one is that my program still doesn't work, I don't get anything at the output. The good one is that the limitations I had with my previous program (using too many logic elements) seem to be solved by this setting. So one question...

    Problem using Max 10's memory blocs

    Hello! Thanks for your reply! > The sig_ram module declaration is not shown. You mean sig_rom, right? The sig_rom is a standard IP from Quartus, I didn't write it myself. I have chosen Library -> On Chip Memory -> ROM: 2port frome Quartus IP menu (on the right). It's a memory of 4096 words of...

    Problem using Max 10's memory blocs

    Hi guys! It's been a while... I'm digging into an earlier project in which I started using arrays in order to generate a sinewave from an external DAC. That was my very first project, and now I'm trying to make it better. Before I forget: I'm working on a MAX10M50DAF484C8G, quite an impressive...

    How to power hardware with USB-C?

    Hello! I have the following problem: I would like to power a device with USB type C connector on the PCB. With micro B, you can use a few resistors to make sure you can get more power than the default 100mA. Does anyone know how to do that with USB-C? I would use a A type to C type to connect...

    Fast pwm generation for h-bridge inverter

    Hello! I'm not sure about what you mean by "fast pwm 16khz for low side drives and 50hz for high side". Usually you want to generate a PWM with a given frequency and a variable duty. I would suggest to do it with a microcontroller, because you have PWM-capable timers on most of the MCUs. Once...

    Timing constraints using a PLL.

    Hello Barry! Do you mean that the phase as defined in the configuration panels of a PLL is not reliable? I have verified that the phase set by the PLL definition is coherent with what I observe on the scope. Do you have any example of a PLL with a phase which doesn't correspond to its...

    Timing constraints using a PLL.

    Hello! There is something a little bit unclear to me. When I started programming a few months ago, I made a generator for arbitrary signals. In order to check how it works, I have loaded a sine wave and the generator just addresses the array and sets the address to a DAC. At one point, it...

    Error (10028): Can't resolve multiple constant drivers

    Hello! Thanks for your replies. I changed the code as you suggested (shift_reg <= {shift_reg[30:0], mosi};) Indeed, by processing many different edges, the code became a real mess, and everytime I tried to implement initialization, I got compilation errors. So I rewrote another version as...
