A little something I have noticed today. I have been developing an application which is using the G431 and uses FD-CAN. My code was working in External Loopback mode such that a CAN message of my choosing was being correctly received by an external d...
I want to save 2 strings of 127 bytes of data in 1 page. 1 page is 256 bytes each. Whern I try to read and write 127 bytes of 1st string, it works successfully. But when I try to append 127bytes of 2nd string,it does not read and write data properly....
Hi I have a code bellow:static void MX_UART8_Init(void) { /* USER CODE BEGIN UART8_Init 0 */ GPIO_InitTypeDef GPIO_InitStruct = {0}; /* USER CODE BEGIN UART8_MspInit 0 */ /* USER CODE END UART8_MspInit 0 */ /* Peripheral clock enabl...
Hi :) I found something quite strange, it seems that:1) On DAC Channel 1 - the output buffer does not work (a 10kOhm load brings the voltage down), but it's output is inverted (as expected)2) On DAC Channel 2 - the output buffer does work (maintains ...
The STM32H743 has various ram blocks available as shown below:DTCMRAM - 128kBITCMRAM - 64kBRAM_D1 - 512kBRAM_D2 - 288kBRAM_D3 - 64kB1) Is it possible to combining (or a subset) of these ram block and use them as one big ram?2) Alternatively is it pos...
seems like the chances of a JVM on an MCU is a nightmare?research show java is supposed to be cross platform, however it makes sense to be able to embed the virtual machine without difficulty first. I can’t even find a successful case online except b...
Hi,I'm using an STM32F746ZG and writing my own custom bootloader. The bootloader will work by initially running and determining which of 2 applications to launch, both stored at different locations in the MCU's internal flash memory. How do you pass ...
Hi guys, I tried to setup frequencies for cores to max which is possible. The code for LL was generated, compiled, but the actual frequency of core M7 (480 MHz) looks much lower than 480 MHz. LL generated codevoid SystemClock_Config(void) { LL_FLAS...
Good evening (o;I know that most GPIO pins can be driven from 5V devices...But how about connecting a 5V bus transceiver? Is that also save?Or better to use a level shifter in between?Reason for asking: Project involving SN75160/161 bus transceivers ...
