I need to achieve level sensitive interrupt behavior with EXTI, similar to shared PCI interrupts on other architectures.Have several OR'ed interrupt requests wired together to a EXTI input;all requests are active low.All requests can be masked or dis...
Hi all, as mentioned in the title i have an issue with the ADC configured to sampling 4 channels with different rank.I want to collect the sample in one array ( array uint16_t values[4] ) in the same order for each conversion done. The data in the ar...
Hi, I have custom HW with STM32L496RGTx. On board I have SD card slot. I tried HW with CubeMX. Setted SDMMC1 to Mode: SD 1, SD DMA - SDMMC1 and divider to 24. In code I wroted: FATFS SDFatFs; /* File system object for SD card logical drive */ char S...
Greetings to all.I'm Following some online courses to learn to program STM32. I have a very weird behavior of my board that gives me not few headaches. After reviewing, changing, testing my codes for 2 days i found a way to get my program running cor...
I am trying to read the register of the chip_id, but the function returns a nDevId that is probably wrong. I set STG3692 switch to obtain SPI configuration and I introduce a GPIO_PIN to configure CS. What could be wrong? below the basicsteps of the c...
HI,So I cannot seem to get the time base that I expect out of Timer 6. I have got timer working wiht the right freqnecy however I cannot seem to get timer 6 to work at the expected freqency. It seems to be running twice as fast to what I set it to.I ...
Hi and happy new year,Migrating from STM32F103 to STM32F303, I mostly copy&paste my code from STM32103 to STM32F303, and only adjust what's necessary. However, I am having troubles with the TIM2 peripheral. Before starting the counter, the CNT regist...
Hi,Device: STM32F103C8T6Driver: LL (low layer)It's been days I have struggle reading BME280 which is connected with i2c to my mcu. After configuration, I'm trying to read registers with standard reading procedure as following:Generate Start condition...
Hi guys, I have a problem with ADC conversion I would say. I put sine wave on ADC input and then I just transfer the value to DAC register, but the negative half of the sine wave is clipped. The code is just this ( Inside HAL_ADC_ConvCpltCallback):DA...
