STM32f429: problem with using external SDRAM as an additional data memory
Hi,I can read/write an external sdram using fmc in stm32f429. But working with address and read/write functions is not proper for my purpose. I want to introduce external sdram as if internal sram is clearly extended and whenever I define a big varia...
Resolved! I have an issue when reading registers using the I2C HAL_Transmit function on a STM32G0
Hello I was hoping to get some guidance on what the best way to read an 8bit register, clear and set a few bits, then write back to the same register using the HAL_Transmit function. I am using a TI LP55231 9 Channel LED driver. Datasheet is located ...
Resolved! ADC not running after wake from STOP2
I'm using STM32L412KBUx on NUCLEO-L412KB, STM32CubeIDE, Version: 1.8.0.Design: ADC1 is set up to continuously poll several channels and update locations in RAM with DMA.After a period of inactivity, the application goes to sleep. COMP1 is used to det...
Please help on the clock configration of STM32G431. The clock is mush slower than what I set. it is only 20MHz roughly
I use cubemx to generate clock configAnd I use a flip pin and oscilloscope to check the speed.here is what i didclock settingvoid SystemClock_Config(void) { RCC_OscInitTypeDef RCC_OscInitStruct = {0}; RCC_ClkInitTypeDef RCC_ClkInitStruct = {0}; ...
STM32L151CBT6 Package LQFP48: Is there something like a list with Pins for the PWM Generation Output?
Hello Guys,I tried to find a list or something which gives me an overview of how many and which pins can be configured as PWM Generation Output for the named µC. In the Datasheet of "STM32L151x6/8/B STM32L152x6/8/B" I found a table named "Timer featu...
Resolved! How to program the cz ministm32F103ZET6 ?
This is the board picture: I bought it from Aliexpress, I tried to connect it to Arduino IDE but didn't connect.There are two boot pins, how to use them ? What should I do exactly ?On the device manager, it displays this message:
User defined irq handler
Is there a way to create user defined IRQ handler type that could be called from NVIC ISPR ? I would like to interrupt execution if some particular software condition is fulfilled..
