I tried to add TIM7 via CubeMX with interrupt on NUCLEO-H743ZI.CubeMX was able to create the init for the timer in the code but it didn't add the IRQ, didn't enable the IRQ and didn't add its callback.I added this code manualy.What I'm missing?
Posted on July 13, 2018 at 03:12I'm trying to put STM32L0 into a low power sleep mode. I want it to sleep for 9.5s and wake up for 0.5s. Once it's awake it needs to switch on LEDs, check for any interrupts from a Lora radio module and process the da...
We are running TIM3 and TIM2 on a STM32F303ZE processor generating pulses on both timer outputs synchronous to an external input trigger. We have TIM3 configured for “Trigger Mode�? with the “External Trigger�? selected running in “one pulse mode�?. ...
Hello. I would like to use low-power timer to wakeup from stop mode (1 or 2).My model is: start LPTIM, generate PWM from one TIM (general-purpose), wait for timeout in stop mode, then start LPTIM again, generate signal etc.I used demo for LPTIM (time...
Hello Everyone,I am using NUCLEO-F746ZG having STM32F746ZG mcu. I was trying the USB device - MSC_Standalone example provided with stm32cubef7. I am using SW4STM32 to compile the example code. The device detects the SD card but when i connect it to t...

Posted on April 14, 2018 at 00:54HiOn STM32H743, using a Linux machine to connect over USB to the DFU bootloader on the USB.We are generally having success at entering DFU mode by pulsing reset low with BOOT0 held high. This has worked hundreds of t...
The I2C ISR register has both TXIS and TXE bit. They are both set when TXDR is empty, and cleared when new data written to TXDR. What is the difference between this 2? Is there any reason I should be using one of them but not the other for master tra...
How can I detect (from a master device) when a slave Acknowledges its address on the I2C bus? I can see on my oscilloscope that the slave Acks its address, but I can't figure out how to detect that Ack from the I2C registers on the master. I'm using ...
