The STM32G4 I'm using supports up to 8 hardware USB endpoints. I'd like to it to enumerate as a composite device with 3 CDC-ACM channels (doing so would greatly simplify the host software). Since each CDC-ACM class device requires 3 endpoints one eac...
Hi ,While exploring flashloader macro using IAR IDE to update Option bytes , I programmed FLASH_OPTR register with Readout Protection level 1.Since then I am not able to communicate to device using STLink and following is the errorIs there anyway I ...
I want to use the FMAC to streamline weighted sum calculations using the FIR feature in non-circular mode. I have an array who's individual values are populated asynchronously via DMA and I use this array as the X1 buffer, but I missed that the buffe...
Hi to everyone!I'm using STM32U535: without HAL, with TIM1, ADC1 and GPDMA1_Channel1.TIM1 regularly (every 312.5us) triggers the ADC1 (MSIK=16MHz,SMP=0b011=20ADC_ClockCycle, 14bits) which performs a sequence of 12 channels with oversampling 4x and wi...
How do we configure the STM32L073RZT6 to produce a 1-second delay using Timer3 without using HAL libraries? Please help me understand the calculations involved, along with which registers need to be configured
Hi there all,I have been looking to power some LEDs which require 25mA supply at 3.3V. This is above the capabilities of this Nucleo-64 board as it is stated that the maximum GPIO supplied current is 20mA per pin (100mA total across all pins).For ref...
Hello,In our application, we need the M7 of the STM32H755 to boot first, and after it initializes to allow the M4 to boot.We set the option bytes per CubeProgrammer such that BCM7 is enabled (checked) and BCM4 is disabled (unchecked). We also set a ...
What will be the total output current sunk by sum of all I/Os and control pins and Total output current sourced by sum of all I/Os supplied by VDDIO2 of STM32F103RBT6?
It is vital to use language and terms with great care and precision in technical writing. Whenever you don't, you create confusion. Newcomers often make the mistake of conflating the terms "crystal", and "oscillator". For example, see @Andrew_Neil ...
I believe there is an error in the STM32G4 Series Reference Manual regarding the width of TIMx_ARR for timers 3 and 4.The reference manual shows a width of 20 bits for TIMx_ARR for timers 3 and 4, below.However, both TIM3 and TIM4 are 16-bit timers, ...
