I have a custom board with STM32H725IG using a multiplexed Octo SPI memory S71KL256xx. I have managed to establish reasonable communication to the memory thanks to example given in AN5050 even tough it was not H7. Sometimes, however, there are read/w...
Heyho,I don't get the FDCAN on a STM32H735g-DK working with 8 Mbit/s.I feed the FDCANs with 80 MHz so that the "time quantum" is 12.5 ns to make 8 Mbit possible with the integers.I use the recommended kvaser website for calculations:https://www.kvase...
Hello! I'm trying to power only the mcu on a nucleo-L152RE dev-kit from the X-nucleo-LPM01A to measure it's power consumption, however i suspect the mcu is not running, and debugging it provides wierd results that I cant make sense of. The program ...
I can't seem to find any ST MCU with less than 17uA/MHz. Is there anything closer to 10uA/MHz ?Also, does ST offer MCU with a bluetooth co-processor?
I am trying to read several adc channels on the stm32 microcontroller, but it won't let me, it only reads the first one. I have seen in the registers that when changing channel what it does is that it sets the selected channel bit to 1 and does not m...
Hi I am using an STM32G071 Nucleo board and would like to know if it is possible to achieve the advertised current of 40nA in shutdown mode.I have no problems entering shutdown mode but the observed current with my nRF PPK2 is closer to 1uA. I have d...
we use the timer capture for Hall inputs. we were able to program the XOR input using the filter and can geneate an interrupt, but I also want to read the individual inputs using the filter.feature. When I read the corresponding IDR it seems it is ...
Hello,I use the internal DAC of the processor. Even the initial value of the DACs are equal, I got 1V out from the first output of the DAC, and 2V output from the other DAC output. Why is that happen?/* USER CODE BEGIN PV */ // DAC Settings float...
