UART buffer receives garbage character(first character) after power on reset to the module connected through UART? Is this expected?But while scoping RX pin,any character is not seen.
I am using STM32F7508-DK and comparing the memory performance of its internal SRAM vs. the external SDRAM connected to FMC (starting from 0xC000_0000).When I turn on the cache, the performance behavior is unexpected. Especially, The external SDRAM is...
Hi,I'm receiving characters in polling mode on USART2 in an STM32L476VG.The USART is set up and enabled. I have the following in my receive character routine:// Get a character from the Aquaflex port // timeout with return = 0 int8_t AquaGetChar() {...
I have to connect 10 devices based on STM32F429x MCU to PC and run them in parallel and send log data from all those STM32F429x devices to PC. Previously when using 1-2 ARM devices with PC I had been using serial port with RS3232 and USB-serial conve...
Hi, i am trying to get stm32l476RET6 to deep sleep ( shutdown or standby mode) following mbed examples, but the processors power consumption i measure is not even close at the correct consumption in these modes.At some point, befote WFI() function,...
Hello,In my project, I connected two MCUs to each other (MISO->MISO, MOSI->MOSI, SCK->SCK). I define a new pin as the CS pin (PORTC.10). But in my receiver the sequence is wrong. Here is my code( For example I send 1234 but I get something else, some...
Given similar memory mapping, COMP and OPAMP (where applicable) is bound to SYSCFG in the various 'F3 models. However, there's no information of the clock enable for these modules in the related RMs. It's presumably enabled by RCC_APB2ENR.SYSCFGEN, b...
Hi,Can i use usart instead of uart???RegardsAdrush
I'm new to micro controllers (but I have a software engineering background) and I decided to purchase a NUCLEO-F429ZI (STM32F429ZI).There are a LOT of pins on this board (168 I/O pins according to the datasheet!). However, if I just want simple HIGH/...
