Resolved! Changing a PWM complementary pins to GPIO functionality and then back to PWM at runtime
Hi,I am running TMR1 CH1 and CH1N in complementary mode (so they are the opposite of each other). Using a HAL function, how do I change each (separately) from PWM to GPIO and back to PWM? Just so to explain what I am trying to do... I am driving a H-...
stm32l072 multi channel adc correct value reading problem
I am trying to read multiple ADC channels using the Stm32l072 microcontroller. As we know VREFINT_CAL is the VREFINT calibration value.but , I noticed that this value is not in the reference manual.(There is no memory adress.Is it a problem ?)I'm cur...
Resolved! STM32H743 (with Cube 1.40) ethernet MDIO usage for PHY manufacturer SMI interface with custom opcode
I am trying to use the KSZ8863 IC and (as shown in Table 3-9 of its datasheet) it has many configuration options behind a tweaked version of the standard MIIM interface. In particular, the opcode needs to be set to 00. I have tried the following:dire...

Thread safety of code generated by Cube
Hello,I'm wondering if Cube's generated code for is thread safe. In particular, whether malloc can be safely used in a multi-threaded FreeRTOS setup.The broken malloc behavior was first described by Dave Nadler in 2019 here. He has also written about...
USB connection between STM32F411 and modem RM500 quectel
Hi I am working on a project where a need to send AT commands through my MCU to a modem, the problem is that this modem only has a USB interface and not a UART interface, so I have a lot of doubts of how should I do this, i wanted to use the USB_Host...
QSPI driver for STM32U5G9 under ThreadX
Hi,I would like to know if you have some examples to implement a QSPI driver under ThreadX for a STM32U5G9? According to my readings, LevelX seems to be appropriate (I am not sure) because we need to implement some basic functionalities (read, writ...
