How to generate a sine wave using DAC with STM32F410RB, using register programming?
I want to generate a sine wave using my STM32F410RB with DAC. I looked up the web for answers but I couldn't find one without using the HAL library. I want to achieve this using register programming only. Your help is highly appreciated. Thanks :)
Resolved! My code works when stepping in debug only, does not work in run mode
I have an STM32F407 Discovery board. My project works fine using the dicovery board.Now it is time to move it to my own PCB, using a STM32F405.As a board "bring up" I tried to run a simple LED toggle program. When I flash the program I get a Download...
Resolved! How can I reduce the time for interrupt callback function execution?
I have this timer that is configured to generate an interrupt after every 15.625 µs, i.e., when it’s period elapses. The timer elapsed callback function contains the code below. The requirement is that new data be transmitted via SPI every 15.625 µs ...
CubeMX: Cannot disable Systick INT
Posted on April 13, 2014 at 13:46Hello! When using CubeMX and going to Configuration and System --> NVIC ''System tick timer'' Interrupt is enabled. When I disable it, click apply and ok and then open NVIC dialog again it's enabled instead of disabl...
Resolved! Minimal FMAC gives wrong answer on STM32G4
I have the FMAC working enough to produce values readable from RDATA, but they are acting strangely and giving small positive and negative values and 0. As a minimal test, I created the below code to have X1 and X2 be all 1s. A buffer length of 18 sh...
Resolved! HAL_Delay() doesn't synch with RTC on STM32H7A3
I'm rewriting some of my old LL code to use HAL and having trouble getting the RTC to read time correctly. I have a simple test project where I'm calling HAL_RTC_GetTime() and HAL_RTC_GetDate() before and after a call to HAL_Delay() with the expectat...
Resolved! 32F413 Port Pin States During Deep Sleep?
I'm the hardware guy on a 32F413 project where we have a lot of impulse noise nearby on the PCB. Because of this I've been on a campaign to make certain that all microcontroller I/O pins are equipped with pull-up or pull-down resistors.The project h...
Resolved! my stm32f4 cannot connect to stlink normally
I am facing an issue with my custom-made STM32F4x minimum system board. I am experiencing unstable connections with the STLink. I am using an AMS1117 for power supply, and I have found that when the STLink supplies power at 5V to the AMS1117, it cann...
Resolved! STM32F410RB DAC Alternate Function not present in AF mapping table
I recently got a STM32F410RB. The block diagram shows "DAC1 as AF". I have been looking up the datasheet to find the alternate function pin for the DAC module in the "Alternate function mapping" table, but I'm unable to. Also, I see DAC1_OUT under th...
