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.

Hello community,I configured the uart dma in my project based on the project example USART_TxRx_DMA_Init, and stuck in frame errors, one of the errors is the end of the string seems to be swapped.Sometimes there is no problem the end of the string is \r\n (0x0D 0x0A) and sometime its 0x0D 0xA0. This is because the dma ends before uart has finished, and another string is sent.I modified the example project so that it continuously sends with few ms delay between each, and no error.How to prevent dma from overwriting previous string data without delay ? (using another IT ?)I got the same issue with the example project and STEVAL-IDB011, you can see in above image, the spike is the dma IT.

Please advise difference between L6206PD and L6206PD013?

Hello,I am working with an STM32MP157 -DK2The Distribution Package currently offers a Yocto version that is aligned with Dunfell (in particular meta-st-linux)Is this repository maintained somewhere in a way that it is aligned with current Yocto releases such as hardknott?Regards

The Clock Configuration tab in CubeMX is not happy and I cannot figure out what the problem is exactly. I only want to use HSE a 25MHz external clock source in BYPASS. And I do not intend to use the PLL. Is this a bug in the tool? How can I satisfy this clock configurator?

Hello, i am using a STM32L0xx series, i just finished my bootloader than can init and jump an application from the specific location in Flash memory, so the only thing left to do is getting bin file (data) from the usart, but how can i send a .bin file from the computer to MCU's usart?¿ i can send hexadecimals, decimals, text etc...but what about binary files?¿The main idea is use a GPRS module (i have it already) and put the .bin file in a cloud and download it finally, but i don't know how to send this....Thanks in advance

Here is what I am trying to Implement. To make the I2C Slave look like a memory to the master. Syntax is one of two cases. For a Write:<Dev Add W><MemAdd MSB><MemAdd LSB><Data0><Data1>...<Data N><Stop>For a Read:<Dev Add W><MemAdd MSB><MemAdd LSB><Restart Dev Add R><Data0><Data1>...<Data N><Stop>I am on the first step. I want to use DMA because I do not want interrupts firing on every byte. My processor has to do other things like data collection, and not just mind the I2C. I think I have to use the HAL_I2C_Slave_Seq_Receive_DMA() and HAL_I2C_Slave_Seq_Transmit_DMA() routines. There is a XferOptions parameter, and I can not figure out what to use for the initial read (from the slave point of view.) . It does not matter which one I use, I get an error. I am looking for one that gracefully ends with a stop or a restart. Because in the write case, they could write 2 bytes at the address, or could wri

Hi all,I've tried every example I can find to send data to a terminal using UART on my Nucleo 144. Every time the code builds fine but there is never anything on the terminal, and the code doesn't get stuck anywhere it runs fine.

Hi all,I'm using the MDMA to communicate with an external flash over QUADSPI.I have an implementation which works great without FreeRTOS, but when I implement it using FreeRTOS I get Transfer Error Address. I have verified that the RAM address exists in AXI memory so it seems like there is something about FreeRTOS that is not allowing the MDMA to read the memory?// Write operation MDMA_Channel0->CDAR = &QUADSPI->DR; MDMA_Channel0->CSAR = pData;   // Read operation MDMA_Channel0->CDAR = pData; MDMA_Channel0->CSAR = &QUADSPI->DR;I've seen the issue with both read and write operations. For both read and write the MDMA_CESR_TED = 0, meaning that the error is related to a read access.This is the flow of the program:[FreeRTOS task] Perform write operation, set volatile flag indicating flash operations are busy[MDMA transfer complete interrupt] Disable MDMA[SPI transfer complete interrupt] Start polling flash status with QUADSPI[Polling match interrupt] set flag

I am trying to initialize my W25Q128jv External Flash in my project, but I am not able to write on it and I think it could be because of the Memory Mapping Mode but I really don't know. For this project I will need my QUADSPI when I will add TouchGFX to save some items, but for now I am only trying to do a for cycle to verify that it works and its performance. If I disable MemoryMappingMode to write, it goes in HardFault.uint32_t *flashbuffer = (uint32_t*)0x90000000; const uint32_t size = 1000;   int begin = HAL_GetTick(); for(i = 0; i < size; i++) { flashbuffer[i]=i; } int end = HAL_GetTick();Here is MX_QUADSPI_Initstatic void MX_QUADSPI_Init(void) {   /* USER CODE BEGIN QUADSPI_Init 0 */   /* USER CODE END QUADSPI_Init 0 */   /* USER CODE BEGIN QUADSPI_Init 1 */   /* USER CODE END QUADSPI_Init 1 */ /* QUADSPI parameter configuration*/ hqspi.Instance = QUADSPI; hqspi.Init.ClockPrescaler = 1; hqspi.Init.FifoThreshold = 4; hqspi.Init.SampleShifti

Hi!I try to set IRQ priority to 3 and subpriority to 2.HAL_NVIC_SetPriority(EXTI9_5_IRQn, 3, 2);I suppose that correspond NVIC IPR [23] now is 0x32. But it is 0x30. I read AIRCR PRIGROUP (it is 3).uint32_t PriorityGroup = NVIC_GetPriorityGrouping();According PM0253 if PRIGROUP == 3, than Binary point is bxxxx.yyyy,Number of group priorities = 16,Number of subpriorities = 16Futhermore I try to use with different input parameters and never get expected results.PreemptSubPrior = NVIC_EncodePriority(PriorityGroup, PreemptPriority, SubPriority);So, so...I am totaly confused with source code of HAL and CMSIS ...NVIC_SetPriority(IRQn, NVIC_EncodePriority(prioritygroup, PreemptPriority, SubPriority));__STATIC_INLINE uint32_t NVIC_EncodePriority (uint32_t PriorityGroup, uint32_t PreemptPriority, uint32_t SubPriority)   { uint32_t PriorityGroupTmp = (PriorityGroup & (uint32_t)0x07UL); /* only values 0..7 are used */ uint32_t PreemptPriorityBits; uint32_t SubPriorityBits; &n

Hi eveyone,I need to use the CR95HF.dll library on a VB.NET application but when i try insert on the project i get an error.I think this library is VB compatible only but i dont sure about this.Maybe anyone know how to port this library to be used on VB.NET or how could i use on NET platform.Thanks.Regards,

Is there a register to set the outputpower on the ST25R3916 like on a Texas Instruments RFID transceiver? Or is the output power entierly controlled by the DPO?
