Hi All,I am trying to send data to SPI1 via DMA1 Stream 0, using a timer to trigger DMA.Currently, I have used TIM4 Channel2 and Enabled DMA Update with DIER register (UDE bit).DMAMUX1 Channel 0 Request is set to 32.So far, this part seems to work: I...

Hi,I would like to make a new electronic design with the STM32G473, using I2C2.But it seems there is a mistake in the datasheet regarding the pinout.On pin description it says:PA8 = I2C2 SDAPA9 = I2C2 CLKPA10 = I2C2 SMBAWhereas on Alternate function ...

Posted on January 16, 2017 at 18:28Hello,I am using a stm32f030k6t6 microcontroller and I have a problem with my pwm function on TIM17..It is very strange: when I power up my controller, sometimes my pwm act as PWM1 and sometimes as PWM2.I didn't co...

Posted on December 19, 2016 at 02:47Hello,I have an issue using the UART RX with DMA on my stm32f030k6t6...The microcontroller reacts exactly like the DMA was not correctly initialized.I'm using USART1 at PA10 (RX), and DMA1 channel 3. Here is the c...

Posted on May 20, 2014 at 16:46Hello,I am trying to get the reference voltage value with ADC (Channel 18).On the VCT6 datasheet, it is said that reference calibration values (for VREF) are stored in memory at the address 0x1FFFF7BA. (Value for VREF ...

Thank you very much!I enabled SSM and SSI bits before MASTER, and it solved the issue indeed!(Before SPE and CSTART is not enough, FYI).Thomas

Posted on January 16, 2017 at 20:49I generally don't use libraries either, I prefer to clearly see what register I am programming, but still I am using them sometimes when I program multiple functions using the same initializing, like here (as I was...

Posted on January 16, 2017 at 19:21Thank you for your response.I have deleted the parts of code that were not relevant for my problem, but I just forgot to delete the part mentioning PB0 and PB1.Unfortunately, I have no access to debugger.I haven't ...

Posted on January 16, 2017 at 18:52Thank you for your answer.Even if the problem was about initializing, it cannot explain the fact that my controller sometimes act as pwm1, sometimes as pwm2 without reprogramming it.There is no 'no-value' in the re...
