Hello,Does anybody know how I can implement SUBGHZ_Phy library:without: HAL library, sequencer, advance trace and debuggerthank you,Sincerely.

Hello,we've connected A0-A2 and VSS with ground. VDD and RESET are connected to supply voltage (+5V).The system does only work with 3V3 not +5V, but we don't see the problem how it's not going to work with the higher voltage.with regardsJulius

Iam using STM32L452RC. I want my controller to go in sleep mode when received an interrupt from USB CDC. While exploring I got these two lines from data sheet The Normal Sleep mode stops the processor clock, but all peripherals keep on running. On the STM32 clock tree, that means:■ FCLK (Cortex Clock) stops■ All the other activated clocks runThis says FCLK (Cortex Clock) stops. Will this affect the timers. I use TIM2 for my project which is a general purpose timer.

HI,I have a custom board with FMC NOR memory S29GL512S11 controlled by STM32H7A3. I created one external loader to flash the NOR memory and works wells. When I try to use the same configurations with the SYSCLK 280MHz and FMC clock 140MHz I can't have any access to the memory.I try to find one way to calculate the right timings for both devices to configure the FMC module, but with the memory datasheet and RM0455 I don't understand how I can make the right configuration.At the moment I have this configuration: hnor.Instance = FMC_NORSRAM_DEVICE; hnor.Extended = FMC_NORSRAM_EXTENDED_DEVICE; hnor.Init.NSBank = FMC_NORSRAM_BANK1; //HAL_NOR_MspInit(&hnor); //HAL_NOR_DeInit(&hnor);   NOR_Timing.AddressSetupTime = 7; NOR_Timing.AddressHoldTime = 15; NOR_Timing.DataSetupTime = 2; NOR_Timing.BusTurnAroundDuration = 3; NOR_Timing.CLKDivision = 16; NOR_Timing.DataLatency = 17; NOR_Timing.AccessMode = FMC_ACCESS_MODE_B;   hnor.Init.NSBank = FMC_NORSRAM_BANK1; hnor

Configuring the NUCLEO-L452RE via HAL using nothing but the default values for the board in STM32CUBEIDE and setting PA8 as the master clock output to monitor HSI16, the clock frequency at PA8 is 16MHz. When configuration is done via LL (Project Manager -> Advanced Settings), the clock frequency at PA8 is 14.7MHz. The ICSCR register has these values:HAL: HSITRIM 0x0 HSICAL 0x9bLL: HSITRIM 0X10 HSICAL 0X6bThe Reference manual shows that the HSICAL value is read only, so I assume it should be loaded at reset by the hardware, and not under software control. I need to set the HSICAL to the correct value while using LL. How can I do this? Note that by setting the HSITRIM to its maximum value only brings the HSI16 up to 15.4MHz while the HSICAL value is 0x6b.

So I planned to Control PWM by using PULSE register. so I wrote one function which will modify the Dutycycle by using PULSE register. But on both channel I get the same duty cycle. I want to generate two different duty cycle with high resolution how can I generate?

When filling the struct in my apptypedef struct { uint32_t RangingProfile; uint32_t TimingBudget; /*!< Expressed in milliseconds */ uint32_t Frequency; /*!< Expressed in Hz */ uint32_t EnableAmbient; /*!< Enable: 1, Disable: 0 */ uint32_t EnableSignal; /*!< Enable: 1, Disable: 0 */ } RANGING_SENSOR_ProfileConfig_t;I am a bit confused about the TimingBudget in it.I followed function calls starting in the nucleo examples atVL53L5A1_RANGING_SENSOR_ConfigProfile(i, &Profile);And this ends up assigning the TimingBudget into a variable named integration_time !integration_time = pConfig->TimingBudget;later I miss the footprints of this integration_time when the api sends its value to a memory_buffer with the function "vl53l5cx_dci_replace_data".Can you confirm this integration_time is the one used in autonomous ranging mode?Then, in continuous mode, if I want to increase the timing budget I must just set up the proper ranging frequency, disregarding the Timing Budget v

i am reading GPIO PIN using bool X[n]; X[1] = (GPIOA->IDR >> 1)&1;X[2] = (GPIOA->IDR >> 4)&1;now i want to inverse reading bit because of pull up i am getting inverse output in X[n].exampleX[1] = (GPIOA->IDR >> 1)&1; gives 1 but i want 0How can i do this ?X[1] != (GPIOA->IDR >> 1)&1; gives warningvalue computed but not used [-Wunused-value}

I am describing my approach as below:What we did:1) We are using the STM32MP157F-EV1 board (No other board is connected for this exercise, lines are open!)2) We are using OpenSTLinux(kernel:5.4) and we are using the firmware which was suggested under the "getting started" guide.What we would like to achieve:1) Want to use SPI1 interface on M4 (alongside RTOS support) and want to use PZ0, PZ1, PZ2, PZ3 Pins only (due to design limitations!)Could you please guide me from here to enable the SPI1 on the M4 side?We have already tried with the default SPI example but It seems the clock is not getting generated. We want to use only a production mode not an engineering one.Let me know if you need any other information/clarification.Thank you in advance and hoping a useful response!!BR,Ashvin

Hi!Forgive me if this is a simple question:This board comes with two OctoSPI:s of 512Mb and 128 Mb respectively, the latter is using HyperBus. Is the default config. setup using any of these memories as the display's frame buffer or is the internal RAM used?If not, is it possible to use an OctoSPI as a frame buffer in general?If yes, are there any drawbacks in terms of performance (e.g. max resolution) for using a OctpoSPI as frame buffer or any other consideration?It would be great not having to route all the adress and data lines on a custom PCB using a OctoSPI as the frame buffer compared to using a parallel SDRAM

Hi all.How to enable the function to collapse text like in the picture below:In CUBEIDE I don't have this function.Thank you for your answer.Kind regards,Oleksii

Hi, anybody,I am using STM32F407ZG/STM32F429IG to build two similar control board. The main function issome host send amount of data, about 1M bytes (STM32F407 with FSMC/SRAM) or 32M bytes (STM32F429 with FMC/SDRAM)to STM32 and stored in memory. Then after some control command, the STM32 MCU control GPIOsto drive another board. The problem is: both STM32F4 MCU claim that they have up to 100M bpstransmit speed, but I only got about 100 kbps.The base code is generated with STM32CubeMX, enabled FreeRTOS with CMSIS_v2 API, LwIP (2.1.2) and mbedTLS (used for&

I have initialise the code in Low layer(No HAL).So now i have config the timer channel as PWM generation output and set clock, ARR,duty cycle as per the requirement. Earlier when I was using HAL, after initialising i can just wrote HAL_TIM_PWM_Start function and it will automatically start the timer as pwm. But now when I'm using Low layer, there is not function for that. So how can i Start the timer in pwm or any mode(output,input compare mode etc.) using the register or any low layer functions. For ref.- There is a register (TIM1->CR1 |= TIM_CR_CEN ) this will start the timer.
