Hello,I am using an STM32F4.I need my mcu to go to sleep (preferably a stop) and i want it to be able to wake up because of a pin or a set timer.My problem is that i am not able to know how much time has elapsed when i wake up because of a pin.Does a...
I am trying to communicate with the QSPI memory on the discovery board STM32F746G-DISCO. I was able to properly read the memory ID (through instruction 0x9E) once. After that any read attempt on the flash memory returned 0xFF, I've tried reading the ...
Hi, everyone.I had used analog watchdog in STM32L052 MCU to monitor supply voltage of device for determinate when it's value will be less then low threshold level (LT in ADC_TR). High threshold I tunned to maximum value (4095).If voltage is between t...
Hello,I cannot use the I2C bus pins to do I2C. That is, I can't use I2C1 or I2C2 or any of the alternate pins. I need to use PB5 as SDA and PB4 as SCK. I haven't found a way to do this in cubeMX, so I am wondering if I can bit-bang I2C on those pins....
Hello, why are the keywords class, public, virtual not in bold font?Where to change this feature?
Recently I bought a CAN Transceiver(SN65HVD230 CAN Board Network Transceiver Evaluation Development Module) to convert CAN_RX, CAN_RX signals into CAN_H, CAN_L from a STM32L476RG Nucleo board. How can I check this Transceiver, whether it is working o...
Hello, We're trying to connect an STM32F469 discovery kit and a Silabs thunderboard 2 through USB, in order to send data between the ST kit and a BLE device using Thunderboard 2.There are two accessible UARTs on STM32F469 dev kit, UART3 which is also...
Hireading the ref manual of the STM32F103C8, it says in chapter 11.10 that the temp sensor is internally connected to ADCx_IN16. In figure 39, it says that the temp sensor is connected to ADC1_IN18.I reckon that this is a simple typo, or do I miss an...
Hi Guys,I'm currently using an STM32L452 device and i'm having some problems with the SDIO when using it with DMA.I have configured DMA and SDIO usign the file generated from STM32Cube tool.When I try to read the SD card without using DMA , everythin...
