HiI am new at CAN communication protocol and working with STM32f407. I used example to run fist communication. I can receive and transmit frames.But the problem is, when a frame is sent from first board to other board, second board goes to ISR receiv...
I have a board with stm32f415 that use the bxcan that continuosly (8 packet every 10 seconds ) trasmit to another receiver board that use Microchip MSC2515 as CAN controller.Some of the packet that i sent from STM32F415 contains all zeros bits. I hav...
Dear all,I'm starting to use STM32H7 for a real-time project and my first task is to optimize the SPI communication. The final implementation will be a library that elaborates data from SPI and send the elaborated data in another SPI (like a pass-thr...
"The operating temperature has an impact on the accuracy of the RC oscillators. At 25 °C, the HSI16 oscillator has an accuracy of ±1% typically, the MSI oscillator has an accuracy of ± 0.5% and the HSI48 oscillator has an accuracy of ±4%."It is descr...
I'd like to develop an application on the dual-core STM32H7 line. To simplify development, I'd like to use the same firmware for both cores. Is this possible?As I understand it, accessing the SCB->CPUID can tell me which core is running. Okay, so ...
I have just started working with Micro controller, I use stm32l496 .I want to init RTC with LSI clock source and HCLK is 2MHz from MSI source. I configure RTC in stm32 cubemx but RTC is not working i.e. the time is set correctly but does not increase...
Hi,I am working on STM32F4 discovery board and I am trying to use output compare mode.and I have written the following code using peripheral registers.The application is Toggle the LED for every 1sec when output compare is matched.Here is the code. B...
I would like to sample ADC1 (ch1, ch2, and ch3) and ADC2 (ch1, ch2, and ch3) in dual simultaneous mode DMA, continuous conversion enabled. Then be able to poll for conversion on other adc channels when needed.
Hello,Looking at the datasheet and the reference manual, I can't find the values of the hysteresis that can be used for the comparators, the datasheet simply states Low, Medium and High values, which is not very precise. Anyone knows the exact values...
