Send commands with CANopen from STM32H7 and canopennode to Elmo motion control gold drive.
Hi,as the title says, I´ve tried sending a OD object (vendor ID, for testing) via CANsend and filling the buffer with the object. I´ve have nothing in response.I´ve also filled the CANsend function with the apropiate code to send data via CANsend()....
How do I generate a clock for other devices using STM32's GPIO
I 'd like to use a GPIO of STM32 to generate a clock for other peripherals. This clock should have the same precision as HSE.Also, the clock should be stable.Also, once set successfully, its stability is not disturbed by running code/interrupts.And i...
How to manually set the values of SP,LR register of a stm f103c8t6 in systemworkbench?
I am following this tutorial to debug a hard fault <timestamp 20:00>. I found that it is a bus fault and tried to access the BFAR register to see the address access that triggered the exception. But the address<0x1826852602> it was pointing didn't ma...
How do I modify the transfer mode of DMA while DMA is running?
I need to change the working mode of the DMA from the general mode to the circular mode, but I don't know if HAL provides a modification method, or other modification method
Resolved! Setting Encoder functionality on STM32F407VE vs STM32F103C8
Setting the encoder functionality on STM32F103C8 is straight forward, just set the registers that's due. But on STM32F407VE it seems more tricky: using PA6 and PA7 on TIM3, if you follow what is said in the RM0090, page 616, you're not ready to go:Fu...
Problem with reading Status Register of W25Q80DV with QSPI
Hello together! :) I am trying to read the status register 1 of the QSPI Flash W25Q80DV via QSPI. Unfortunately I don't get any data in the buffer. I only get 0x00. The topic of QSPI is still very new to me, so I may have overlooked something obvious...
TIM8_CH2N for PWM
I try to setup the PB0 for PWM mode to drive a LED.When I use the TIM3_CH3, it is working with the following code.But it does not work for TIM8_CH2N.I suppose something to do with the "N" but could not find out what in HAL code should be changed.TIM_...
Using DAC output for class D audio amplifier
I'm wondering what would be an ideal circuit to connect a very simple 2-4W class D audio amplifier to a DAC output of an STM32 MCU.My goal is to be able to play some WAV files using build-in DAC of STM32F051.I found an amplifier TDA2822G-S08-R, took ...
