Resolved! How to disable HAL_TIM_PeriodElapsedCallback on a timer
Hi I would like to know if I can still get the interrupt updates of a timer but disable the call to the callback HAL_TIM_PeriodElapsedCallback.
How can I change the "Maximum output speed" for the GPIO output to toggle faster ?
I tried to get the minium delay between output state but I am limited by the GPIO toggling speed, I even tried PWM generation and there is an option on GPIO settings -> Maximum output speed but I can't change it by clicking on it.Does anybody has an ...
Resolved! [STM32g0] Multiple I2C target transmitters transmitting data in the same I2C transfer
Hello, this will be a rather advanced problem that I'll be presenting so please bear with me until the end.I'm currently working on I2C communication, with a configuration where I have a controller that initialize 4 STM32g0 on custom PCBs.TL;DR : I w...
Resolved! Problem using TIM3 on DMA1 on STM32G030J6
Dear to All,I have a boar with STM32G030J6 and I want use the TIM3 as PWM output (on PB0->TIM3_CH3) using DMA1 channel 3 to transfer data from RAM memory to TIM3_CCR3 register. The problem is that DMA never trigger the interrupt!Here the code:// Setu...
Resolved! Using stm32g0 RTC as an external RTC for another system/board
I noticed this driver https://github.com/EmcraftSystems/linux-emcraft/blob/master/drivers/rtc/rtc-stm32f2.cIs it possible to configure the stm32g030c8 to be an i2c slave and provide it's RTC to an external system that runs linux and uses this driver?...
Resolved! Is there any software like proteus where I can simulate STM32 MCUs??
Hello, I want to know if there are other platforms like proteus in which I can virtually simulate STM32 MCU and OLED display.STM32 programs are not working in proteus. I just used simple toggle LED program but it is not running on proteus,
Uart3 in stm32f103c8 not working
hi,i am trying uart with dma in stm32f103c8 with uart3 after n try i found that uart3 in stm32f103c8 is not working then in polling I observed that the TX pin is not getting high and low so I toggle that pin it toggles as a digital pin so I think t...
why can't I change the clock
I inherited someone else's code who knows more about the STM32L1 architecture than I. In some code paths, the HSI can get changed to 8Mhz from the HSE of 32Mhz, and sometimes it can't.It fails because of this loop timing out.do { HSIStatus = RCC->C...
I need help with I2C between a Arduino board and a STM32F103
I have been trying to make the Arduino talk to the STM32 via I2C but i just cant get it to work. The STM has to be in a form of a slave mode but i can't seem to figure it out. So if there is anyone who could help me or give me a form of an example fr...
