Hello, On one hand, I built an app that uses I2C, 2 UARTS, ADCs, captures PWM, provides PWM. All of them rely heavily on the use of DMAs. This app gives good results without any apparent issue. On the other hand, I built a test app on the same tar...

Hello I'm evaluating B-G431B-ES1 design.As I don't have accurate specifications for the motor, I'm going through motor profiler. If I use SDK 5.4.8, profiling seems to work. At least, the motor turns.If I use SDK 6.3.2, profiling whistles while keepi...

Hello, I'm trying communication between stm32G0 as I2C slave and a rapsberry pi 5 as master.on pi side, the call is: self.cpt = (self.cpt + 1) % 255 b = self.bus.read_i2c_block_data(42, self.cpt, 5); I've seen in several places on the web tha...

Hello STM32G0B1 For some obscure reason, sometimes the systick handler function is not called anymore.I mean, it works for some time then it does not work anymore. It looks like it is more likely to happen when I'm debugging but I have no factual inf...

Hello, With stm32G0, I can capture a pwm frequency and duty cycle using this configuration:DMA : Now, for pinout reasons, I want to do the same thing using channels 3 and 4 instead of channels 1 and 2 but I can't find a correct set of settings.On pa...

Hello Andrew,Thanks for the interesting pointers. Unfortunately cortex-M0+ offer less features than M3-M4.Anyway! Here's what I get:SP : 0x2002 3F88Extract from memory dump at this address:If I did everything well, the instruction that causes the err...

Hello again, Going a bit further:- I was able to remove tim3 from configuration while keeping the hard fault. Remaining peripherals interrupt handlers, are: void DMA1_Ch4_7_DMA2_Ch1_5_DMAMUX1_OVR_IRQHandler(void) { /* USER CODE BEGIN DMA1_Ch4_7_D...

Test 1:- I removed esc feature.- opened motorpilot- loaded gui SimpleAppMCPV2.qml- error -> this gui does not support motor profiling app (something like this).- removed motor profiler from "application configuration" tab - restart gui.- motor runs s...

I supposed that the test you asked was motor profiling. I disabled electronic speed control (even if plan to use it in the future).I ran motor profiling. The result is better but not fully successfull. Video below.I tried several combinations of rpm ...
