Hi folks, I need to use setup system where is 10BASE-T1S communication. And we have stm32H7 controller, so questions is which one would better use LAN8651 (MAC+PHY) chip and do controlling of chip via SPI or chose LAN8670 (PHY) and do chip controll...
I want to send data from my STM32 to another micro controller and I want to enable space parity, there is no setting to enable it, the only settings are none, odd and even. For space parity i want the parity bit to always be 0. I am using 9 bit UART...
Hello everyone,I am experiencing a fairly impactful problem with STOP3 mode in a FreeRTOS application that runs in a STM32U585VIT6Q.The system has this behavior: it wakes up, performs operations on SPI3, write some informations on internal FLASH, ret...
I am just switching clock source to MCU in RCC_CR register by making HSEON bit of above register high and waiting till HSERDY but turnsup. But thing after HSERDY turns up when I read rcc_cr register both HSEON,HSION bit of RCC cr are at logic 1. Then...
I'm trying to use the RAMECC monitoring subsystem on an STM32H743 but there's some behaviour I don't understand. I've read the reference manual (RM0433 rev 7) and application note AN5432, as well as some related forum posts here.If I set an interrupt...
Hello, I'm trying communication between stm32G0 as I2C slave and a rapsberry pi 5 as master.on pi side, the call is: self.cpt = (self.cpt + 1) % 255 b = self.bus.read_i2c_block_data(42, self.cpt, 5); I've seen in several places on the web tha...
OverviewAt my job, I was recently tasked with handling ECC errors in both RAM and flash memory. Additionally, I needed to test the error handling by injecting ECC errors. Figuring out how to do this was a nightmare. I looked over AN5342 countless tim...
Hi,I am currently working on a Battery Management System (BMS) and an instrument cluster. I need your assistance with some issues I’m encountering while communicating between the BMS and a custom cluster board using CAN.We have two custom cluster boa...
I am trying to make a custom external loader for a qspi nor flash. the erase sector and write operation is success but after I tried the read operation the operation is fail the device is disconnected and showing this message I have tried to run a pr...
I generally don't open threads, but one recurring frustration I've had with Keil on CM0(+) platforms is with printf() going off the rails with "%.2lf" "%.3lf" type formats.I've seen more often than I care for, a situation where code working elsewher...
