Resolved! Why the number of data I sent is wrong when using HAL_SPI_TransmitReceive() ?
HAL_SPI_TransmitReceive(&hspi1,tx_sensor_data,rx_sensor_data,8,0);I want sent 8bytes, but only 2bytes sent, why?

Resolved! Reading from external Flash with QSPI not working.
I am working with STM32F&508-DISCO, which is said to have external Flash of size 16MB connected through QSPI. I am trying to read from it, but it is not working.I tried running this: https://github.com/STMicroelectronics/STM32CubeF7/blob/master/Proje...
Resetting SCLK polarity after changing SPI mode through HAL (STM32F7xx)
We're developing for the STM32F767, primarily using the HAL. We have devices on the SPI bus which require different timing clock polarities. Re-configuring the SPI hardware through repeated calls to HAL_SPI_Init works, however, the actual hardwar...
Can ADC1 analog watchdog trigger TIM8?
Is it possible for any of the analog watchdogs of ADC1 to be used to trigger TIM8? I would like to stop a PWM generated using TIM8 when an ADC1 conversion crosses a threshold. Table 251, Interconnect to the tim_etr input multiplexer seems to indicate...
Debugging temperature sensor data collection on STM32F303K8, cannot collect DHT11 sensor data?
I am using UART to display the live readings of my DHT11 sensor similar to this blog post https://controllerstech.com/using-dht11-sensor-with-stm32/ and my program seems to stop around the DHT11_Read() or DHT11_Check_Response() functions. It seems t...
Resolved! UART works on terminal but not getting output on pins of Nucleo board
I followed the UART example (https://wiki.st.com/stm32mcu/wiki/STM32StepByStep:Step3_Introduction_to_the_UART) and implemented it on a STM32F051 Discovery kit and on a STM32F446 Nucleo board with pretty much identical settings from CubeMX.If I scope ...
STM32F412 clock config issue
I made a custom board with an STM32F412RE chip and I can program it, and step through my code, but when I try to initialize my system clock I get stuck in a while loop that times out that I don't think should.[Here](https://imgur.com/a/Jqa1JmG) is my...
Resolved! STM32F429: How to correctly read timer counter register during ISR?
I'm converting the CubeMX usb audio device example to be audio class 2.0 compliant, with high-speed external phy.I have to implement a feedback endpoint to report the current number of samples per microframe. For this, I have tim2 set up as external ...
STM32 as I2C slave - sporadic errors - how to diagnose?
EDIT: Note change of direction of things in 3rd post.I have a stm32f091, which has a program that basically runs one mainloop that triggers ADC measurements and polling values from i2c chips using the i2c2 peripheral in master mode. ADC uses a DMA ir...
