I try optimize to maximum MCU offload this operation:I2S DMA stores sample LRLRLRLR... circular i need reorder it to LLLLLLRRRRR in other memory place.I mean DMA or other hw methods cant copy mem to mem with skip defined, mean every other.Then i try ...
I have 8 GPIO pins where I want to read the state of the pin. I want to do this with a DMA controller. My guess is that this should be done with perhipipal to memory. The code is shown in the txt. file. When the DMA is finished it goes into an inter...
I'm sampling at 100 msec and adc is in single mode with PRESC_PCLK_DIV6 and SAMPLE_480CYCLES.
So I’m trying to sample 2 analogue signals with the use of DMA. The ADC’s are running on highest possible speeds (core clock). But when I’m looking at the results for some reason one ADC avoid some “lines�? of value’s and instead of giving the right ...
HelloI using STM32F746 Dicovery kit.USART callback worked before!!! All communication worked normal and both callbacks worked.I did a mistake. Installed new stm32cubeide_1.6.1and removed an old IDE.Now callback for receiving is working and transmit c...
Hi all,I'm trying to profile my application which running on STM32F469IH6 micro-controller. I'm able to run the application in debug mode and able to see the timings of the applications.But In generally running application in release mode will have m...
The RM0444 Rev5 show 36 EXTI lines in Table 62.The HAL code defines up to 37 lines:/** * @brief EXTI Line number */ #if defined(STM32G0C1xx) || defined(STM32G0B1xx) #define EXTI_LINE_NB 37uL #elif defined(STM32G0B0xx) #def...
Dear STM-Community,It might be true that all of us have a micro-usb cable at home, but due to smartphones,tablets,... the way more convenient USB-C plug is the new standard on the market.Therefore I would like to start some upvope for a awesome USB-C...
Fecha. 29-04-2021.Pedro A. Fernandez. Para quien pueda explicar los motivos de la mala funcionalidad del periférico i2cHola, recientemente comenze a programar los micros STM32, con el modelos STM32F103C8T6 montados en la placa Blue Pill, ini...
I've connected a CR2032 battery to the V_BAT pin on my custom STM32F746 board. Right now, the battery is connected directly without a Schottky diode. When I power the board off and on again, though, the RTC is reset to zero values.According to the ...
