HI All,I Have the STM32F302R8. I am using comparator 2. What I want to do is have DACH1 feed a value to the inverting input and have PA7 connected to the non inverting input. For now, I am just wanting to generate an interrupt to get things working ...
I am using an NUCLEO-F429Zi to read a MPU over I2C ( 2C1, PB8, PB9). The applications works correct. The sensor returns the correct values. When the ST-Link is removed (cut away) from the board, the power supply Vin , the I2C connectivity fails. It ...
i can switch between all pin but this one is static, pin PC14 (I call it olcl).I think maybe one of the peripheral units in the card is catching it to me.this is the code and the setup.sbs_pol_Pin is swiching states properly. while (1) { HAL_GPIO_Wr...
I am using NUCLEO-G474RE as my hardware.STM32CubeIDE V1.3.1 and STM32G4 Fw V1.2.0.I am using ADC2 with 4 channels triggered by HRTIM CH B Compare 4 Injected.So these 4 channels are triggered interleaved, meaning that every HRTIM-CH-B Compare 4 only o...
Hi, I would like use the DMA functionality for SPI on my STM32F4. But all examples I have found are calling the SPI DMA Transmit Receive function in a while loop. But what would be a better way? I think that if I call the Transmit Receive function ...
I'm using the project "SPI_FullDuplex_ComPolling_Master" in P-Nucleo-WB55.Nucleo/Examples_MIX/SPI in FW version 1.6.0. Works fine on the nucleo board. I've ported it to my board which uses pins PB5, PB4, and PB3. I'm using a crystal on my board. I di...
While trying to read ADC value over voltage divider I accidentally connected not divided voltage to ADC pin. That was about 10V and with burnt smell I promptly intervene and cut the connection. The board was hot but I could touch it. After that I pu...
Hi all,I am considering the STM32L073RZ for a low earth orbit application. Would this MCU be suitable for the following operational environment?Altitudes of 590 – 630 km.Temperature environment range is -40°C to +70°C.Total Ionizing Dose (TID) exposu...
Hello everyone, I have medium level in stm32 mcu's like using adc's, timers and also HRTIM peripheral in 32f334 and G4 series but I can't figure out the optimum way to generate three level spwm waveforms for using with NPC inverter that I'm designing...
ref: https://www.st.com/resource/en/application_note/dm00110292-implementing-an-emulated-uart-on-stm32f4-microcontrollers-stmicroelectronics.pdfDue to pin restrictions, I've forced to send data on two GPIO pins not wired to any uart on the 152. I've ...
