Hi, Im senior engineer using stm32, maybe, not newbee.I know that Higher interrupt priority can occur when mcu still process lower interrupt.Higher interrupt , i mean, lower priority value in nvic register.but just now, I found gpio interrupt can dis...
I do not understand the difference between the different sampling rates (cycles3 - cycle480). I know it is related to the time given for the ADC capacitor. I also realise that more time should mean more stable reading. I ran some quick tests and I f...
I have a Value Line Discovery board - STM32F100RB and three of the outputs are connected to a 3v3 converter to get a 5v output. I have tried another controller board with 3v3 outputs to drive the convertor board and I get a clean signal. (Either 0 or...
I'm a bit lost by this one. I can write to the flash but cannot erase a sector. I can erase sectors with the ST-Link Utility. The result codes at every step indicate success, but the flash is not actually erased. I am using the Standard Peripheral Li...
I am using STM32L431RBT6 consuming 2.63mA of current. How can I further reduce the current consumption ?. I am using MSI at 8 Mhz , and peripherals used are SPI1, SPI2, UART and I2C.
I'm using STM32F429 and trying to use HAL library to communicate to SPI slave via DMA channel. I'd like to ask how is resolved problem with for example sending data to SPI via DMA? Is there any kind of synchronization between SPI and DMA to disallow...
Hello,is there any way to achieve this timer OPM behavior?Arm timer ->Output is inactiveStart timer-> Output gets avtiveCompare register triggers -> Output gets inactiveARR triggers: Timer stops _and_ Output stays inactiveAt the moment, I force the O...
