how Mach resource required for run led display in stm32H757i evk ?i am working on stm32H757i evk, my actual product have not external ram.but i have run lcd display in my project.without external ram i can run display?my display is not more sophistic...
I dont know why this error happens. It is aligned as 0x0800F800.Not only this, but i get a hardfault (UNDEFINSTR) error too, while printing the above error with the following:printf("Error writeFLASHDoubleWord FLASH->SR: %02X", READ_REG(FLASH->SR));
Dear SIR, We want to use STM32G0B0 to develop our project. We want to use EVK to write code before our board comes.But there is NO STM32G0B0 EVK, only STM32G0B1 EVK exist.(or NUCLEO-G0B1RE, https://www.st.com/en/evaluation-tools/nucleo-g0b1re.html)Ho...
Hello,I'm using a microSD connected with SPI to a STM32F4 microcontroller. I have used MLC micro SD card with fatfs for years without any issues. Recently, I have switched to SLC NAND micro SD, Industrial grade, with Wear Leveling (for application sp...
I got two things i dont understand or needs more information. In the manual it says"The Flash memory is programmed 72 bits at a time (64 bits + 8 bits ECC)."I somewhat know about ECC, but i dont know about the "8 bits". Can i just ignore this? Progra...
Hi All,I am trying to implement a code on STM32H723 Nucleo-144 where the ADC uses DMA configured in double buffer mode. I cant find any examples on how to do it. I have tried to analyze the ADC to DMA in circular mode code, but I struggle to convert ...
Hi community,I am trying to port a project from old library maple leaf or older built for Arduino to to STM32cubeIDEthis function I couldn't find any ref to it, my guess it that is sets the period to 5ms Timer3.setPeriod(1000 / 200); browsing some th...
Hi I am using the USB CDC on a STM32L433 with the command MX_USB_DEVICE_Init(); to communicate through the USB. In my app, I go into standby mode (by using the HAL_PWR_EnterSTANDBYMode()) command. How do I disable the USB before entering standby? I ...
Hello,I've enabled a USB virtual com port on an STM32F373 successfully. The CDC_Receive_FS function in usbd_cdc_if.c gets called when data is received. I never expect to never receive a 'packet' greater than 64 bytes and have created my USB buffer[...
STM32F051C8T6产品，想用来和多摩川的编码器产品通讯，发送数据0x02，多摩川编码器发送6个字节返回。但用6个字节的中断得不到数据，用6个字节读取也无法得到数据。中断只能收到一个字节，02。有指导问题出在哪里了？
