Re: STM32F746G problem to run Topic is solved

Is this the same problem that causes download and debug problems for the stm32f3 cdc demo? I am using chibistudio 21 and get... symbol-file C:\\ChibiStudio\\workspace_user\\Bubba_Drive_V1\\build\\ch.elf Reading symbols from C:\ChibiStudio\workspace_user\Bubba_Drive_V1\build\ch.elf...done. set remote...

Re: VESC, and B-G431B-ESC1 and stm32g4xx development progress...

The stm32g431 port is really the key item to porting VESC to the B-G431B-ESC1. Of course it uses both the ADC and the CAN interface. Although it can work without the CAN for starters, It needs the ADC. I will start looking at the ADC drivers, but I haven't done any driver work on Chibios... -John Sc...

VESC, and B-G431B-ESC1 and stm32g4xx development progress...

I just got a couple of the ST B-G431B-ESC1 eval boards and I am getting ready to start playing with them using the ST Motor Lib, and notices that there seems to be some work going on here for the st32g4xx chip. How is the progress going on the hal? JMifune, any progress on porting VESC? It would be ...

Re: Using ChibiStudio for non Chibios project...

Great, thats what I expected, but there is a lot of Eclipse and openOCD stuff that I don't understand, So I figured I would ask.

I assume I can use the debug configuration from a stm32f1 demo as a starting place?

-Thanks

Using ChibiStudio for non Chibios project...

I have been handed a working stm32f1 project that needs some major rewriting. The first things I need to do are add some additional functionality quickly. That I can handle. However, I need a build environment... Can I import a non-chibios project with all its includes and make files? It is assumed ...

Re: help using ultrasonic ranging module with STM32 nucleoF401RE

You have a delay problem... Here you have a delay function that delays for n miliseconds void delay(int n) { chThdSleepMilliseconds(n); } Here you call the delay function with a value of 100. This is going to delay 100 miliseconds not 10 microseconds. //GPIOA_PIN8 (PA8) trigger, GPIOA_PIN9 (PA9) ech...

Re: GPT Jitter

AH.... Yes, not a great solution. You end up with a really long time that your processor is tied up doing nothing but looking at its watch and waiting for something to happen... So with PWM you will select your time and just change the frequency on each output bit. you might try 0hz for off, then wh...

Re: GPT Jitter

Hi Sven, I have a couple of questions about your modulator callback. It looks like you are sending data at 1200 BAUD to two samples per BAUD. Correct? You are configuring the GPT to clock at 180,000,000 Hz (180MHz). You are calling your callback at 720,000 Hz. Do you really mean to call your callbac...

Re: GPT Jitter

That kind of what I was thinking also. Any jitter that you would have not be a problem. It would be a very small fraction of the 1200 baud signal. 1200 BAUD should be Real Easy on resources for this processor. But I am wondering if there is more to this then meets the eye. He is calling the callback...

Re: [WARNING] SourceForge DOWN (now back up, notes inside)

There is a export function on SF, but I don't do much with SF so I don't know just how much it helps. It looks like it handles Tickets as well. Output is JSON, so you would have to import it somewhere else or write a conversion program... Might be something to spend a few minutes looking into if you...
