Stm32F412 SPI interrupt full duplex slave.
Hi I am working on stm32F4 on spi communication. I am using stm32F4 as slave module and i have other qualcomm board as master module. as in master module there are 5 pins as MOSI,MISO,SCK,CS,INTR. when I am generating the code for stm32f4 using cubem...
STM32F4 SPI slave TX/RX error: how to reset SPI?
Hi, I'm using an STM32F413RG MCU as SPI full-duplex slave, initialization is done in Cube. Every 500ms the master activate the SPI_CLK (1MHz) and the MCU outputs 16 bytes of data while receiving other 16 bytes from the master (using HAL_SPI_TransmitR...
F767 TIM12 PWM HAL not working
Hi,I tried really hard to get the TIM12 working, but I had absolutely no success... I already do PWM on TIM1 and TIM4. So I tried with same settings to setup TIM12, but it does not work. The question now is: Why?What do I use?STM32CubeIDE 1.3.0I set ...
"No device found on target" using STM32F730R8 breakout board. Schematics and layout inside.
Hi! So, I attempted to make a breakout board for the LQFP64 package of the STM32F730R8 and I can't seem to get it to work somehow. Whenever I try to upload a program to it, I get a "No device found on target". If anyone has an idea or pointers, that ...
Resolved! Using RTC on STM32l4 as a fail safe monthly wake up?
Wondering if the STM32l4 RTC could be used to wake the processor from standby mode after 1 month.Powered by the LSI, would the time drift beyond usability? Ie. It does not matter if the device wakes up 30 days or 31 days later. Just as long as its in...
Resolved! STACK and HEAP size
Hello everyone In Keil Projects we are able to change Stack_Size and Heap_Size in "startup_stm32f746xx.s" file like this :Stack_Size EQU 0x400Heap_Size EQU 0x200BUT in IAR projects there isn't such code line in the startup file related...
Connecting two STM32s using a serial port causes overrun problems
Hello, We have an application where we want to use basic serial ports to communicate between two STM32 processors (32F030RCTs). The two processors are on two different boards but with the same ground system. Each processor receives and transmits per...
Weird triggering of SPI interruption on STM32H743
I'm facing a weird situation. I'm using SPI simplex receive-only mode on a Slave STM32H743. It has been working fine for a while. Until now I was enabling only the RXP interruption. The SPI1 interrupt was triggered as expected.Now I enabled also EOTI...
Resolved! Frequency range of LSI for STM32L072CB
Hello,according to the datasheet of STM32L072CB there is a margin of controllers which have at 26kHz@Xx°C or 56kHz@Xx°C (first row of table)?So in total there is a production margin (26kHz to 56kHz) and additionally a temperature drift during run tim...
