Hi,I plan to use LAN8742A and STM32H7 for an ethernet application.In the datasheet for LAN8742A there is this very interesting sentense on page 34 i the datsheet:The REF_CLK Out Mode is not part of the RMII Specification. To ensure proper system oper...
Hello, how can I get timers running at 480Mhz to have maximum resolution?Here is a capture using latest stmcube version:I have tried D2PRE1 & D2PRE2 =1 but then warnings appear
May I ask whether ST has STM32F412RGT7 model and Operating temperature to 105°C.TKS!
I am looking for a MCU that can replace NXP MCF5282CVM66.
Hi,It may seem simple to you, but it confuses me for a bit of time after I saw:uint32_t isrflags = READ_REG(huart->Instance->SR);and#define READ_REG(REG) ((REG))I have 2 questions here:huart->Instance->SR should be an address, how does READ_RE...
I need to check to outcome of a FLASH write operation. EOP would indicate, that it was successfully, but it needs the interrrupt to be enabled to show the outcome. Oh well, then i use the error flag instead (because i dont want to use interrupts). Bu...
Hello, when I try to compile the code in the Stm32cubeide program, I see the error that the flash.ld file does not exist. And there is no file with flash.ld extension among my files. It is not created by stm32cubemx.
Hey there !I'm trying to use an ultrasound range captor on STM32 Nucleo. To beggin, I'm on a very simple case of use : User press a button, it's trigerring an interrupt, handled by a callback function `emettre_ultrason()`. Then, when the callback fun...
on STM32U575 when I enable the ECC, it is throwing a Hard Fault. I am just doing RAMCFG_Init() & StartECC() as of now. The system keeps resetting. TrustZone is enabled for the project, will that make any difference?
Hello,I need to implement an i2c passthrough between i2c ports i2c1 and i2c2 on my stm32g031k8 board. This MCU is connected to another CPU board using i2c2 port. Also, the i2c1 is connected to a temperature sensor, RTC, and EEPROM. After power UP, u...
