Resolved! CAN interrupt is not called
Hello,I am trying to set up a CAN interrupt base communication system and it seems that IRQ handler is never called.Debugger goes through the CAN1_TX and then back to main function, so IRq is never called.USART output:[2020-12-08_21:19:01:191] A...
Resolved! Issues with SPI comms between two STM32s
I'm trying out simple SPI comms between two STM32s. The TX is STM32F407 and the RX is STM32G070. The data that I seem to be receiving is different from what I'm sending. What am I missing here?For the RX, I've set the NSS to software. I've configured...
What's the lowest power way of using a Timer to divide by 2 ?
I need to divide a 24.576 MHz signal down to 12.288 MHz for a low power ADC so thought a timer would do this easily. But either I'm missing something or I have to put a value of 1 in the compare register and reload the counter all the time which see...
Trouble setting D2 clocks
I'm trying to set up the clock tree, and D1CKRDY becomes ready, but for some reason D2CKRDY does not. Here is the code:// Clock setup RCC->CR |= RCC_CR_HSEBYP; // Set HSE as...
Changing data for DAC every 1 sec
Hello,I currently use the STM32G4 MCU Nucleo board (NUCLEO-G474RE) - I create an array of numbers (specifically - a sine wave at a certain frequency), which I transmit via the DMA, triggered by a timer (TIM2). Currently, the array is being transmitte...
Resolved! STM32F042 CAN bus receive problem
Hello,I want to receive messages from CAN bus using STM32F042, but I have a problem with it because the interrupt is not working.I can send messages without any kind of problem, the problem is only with the receiving.I have set up the filter as it ca...
Resolved! Disable internal SMPS by Harware STM32H755IIT
Well I tried to read the documentation, but found only HW requirements to use SMPS. So is the SMPS required?Or can the SMPS just tie VDDSMPS, VLXSMPS, VFBSMPS and VSSSMPS to ground directly on PCB when no needs for that?
Use basic DFSDM on STM32F12ZG
Hi,I am trying to record audio on a STM32F412 with an MP23DT05-A (digital MEMS microphone made by ST) using DSFDM.After basic configuration in CubeMX the project does not compile. The error is a missing function: undefined reference to `__HAL_RCC_D...
Resolved! Using SPI with STM32L4R9 Discovery Board
Unfortunately there isn't an example provided for SPI on the STM32L4R9 Disco board. I can tell from the User Manual that I need to set the quad SPDT switch on the board to the SPI configuration. If I understand table 20 in the User Manual, I need to ...
