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...
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...
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?...
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,
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...
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 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...
Hello,I have an issue with my DAC. I am using a Nucleo STM32L476RG and my project consist of acquiring data from a mems microphone over i2S using the SAI and then send it to the DAC in order to view it with an oscilloscope. First I initialize the DAC...
Hello, i have some questions about current injection onSTM32G431CBT3 pins.On datasheet Table 15 it is reported:IINJ(PIN) -> Injected current on FT_***, TT_xx, NRST pins ->-5/0NOTE3:Positive injection (when VIN > VDD) is not possible on these I/Os and...
Dear community, I am facing a weird problem on using the SPI after migrating my codes from STM32F407 to STM32F767.The SPI is configured as slave and interfaces with another STM32F406 MCU as master. The data received by the slave is sometimes shifted ...
