VCP with STM32F429I DISCO
I don't understand why i can't use VCP on my STM32F429I-DISCO even if UART RX /TX pin are connected to the USB-ST-link. I know I have to flash this ST-link V2 to V2.1 to have the VCP activated but i can't do that.You can see on the attached schematic...
STM32 I2C Slave mode HAL bug
Recently I have tried to implement a solution employing I2C interface in slave mode.The solution follows the pattern presented in the official I2C_TwoBoards_RestartAdvComIT example available in CubeMX packages and another solution presented here: STM...
FMC/FSMC ECC computation
Hello, guys!I have a quick question about FSMC's ECC routine.From what I understood, the workflow goes like this:1) Enable ECC computationSET_BIT(hnand->Instance->PCR, FMC_PCR_ECCEN);2) Write data to the target device3) Get the computed ECCwhile (__F...
This is on the STM32L053R8T6 Nucleo Board. Is there an error on COMP1&2 working in Window Mode?
This issue had been brought up almost a year back, and there looks like there has not been a fix to the libraries?So basically, after code generation with STM32CubeMX, under MX_COMP1_Init, hcomp1.Init.WindowMode = COMP_WINDOWMODE_COMP1_INPUT_PLUS_COM...
STM32F7 SMBUS vs STM32F4 SMBUS
Differences in setting up for SMBUS:On F4, I set the following bits in CR1: PEC POS ENPEC SMBTYPE SMBUSOn F7, are there similar bits?I see PECEN - is that the same as ENPEC on F4?How do you set up SMBUS on F7? (on F4, it was done with SMBTYPE and SMB...
Resolved! ADC noise on stm32f401
I've been messing around with a LMT86 temperature sensorThis sensor is deemed high output impedance as the documented loads it drives is 50uA.ADC noise on STM32 isn't 'new'. Just that for a first time I'm observing such volatility up close. The probl...
stm32f429 shortage
Hello everyone ; I dont know if this is the right place to write ; we are using stm32f429 in our products we use about 20K / year . we are doing the plan for the next year we are getting a long ..very long shippng dates like 80 weeks ! even now we...
Trouble with SDCARD - SDMMC_FLAG_RXOVERR
I'm attempting to connect an adafruit SD card reader via SDIO to a Nucleo L476RG.I'm reading through the source code to do a test of the basic read/write functions.Initialization and getting card info is successful. if (HAL_SD_Init(&hsd1)!=HAL_OK){...
