I'm working on an application where the amount of wires is limited. In order to update firmware, the only thing I will have is a single half-duplex RS485 transceiver connected to the UART. I was going to connect this to a single UART pin in single-wi...
Hello,When I plug this board to my computer, appears a removable disk of 1,6 MB capacity.Is this disk accessible from the MCU? For store small data, or make a dataloggerWhere the filesystem is stored? Neither the STM32F446RE nor STM32F103CB of the ST...
Below is my following CAN configuration. Extended CAN frame is transferred every 50ms at 1MB/s.static void MX_CAN_Init(void){/* USER CODE BEGIN CAN_Init 0 *//* USER CODE END CAN_Init 0 *//* USER CODE BEGIN CAN_Init 1 *//* USER CODE END CAN_Init 1 */h...
Hello,I'm trying to write a program into a "STM32F334C6T6". For programing I want to use serial communication (UART1) and terminal (CoolTerm).So far I got a success with Get, Get ID and Read Memory commands. (refer to this manual https://www.st.com/r...
Hi,i'm using Keil and i'm trying to see my variables on STM Studio. I installed it today. But it doesn't work. A few days ago i replaced my D1 with D2. Because i broke down my D1. Is this can be the reason of the problem?
i have flashed a stm32f103c8t6 with freejoy code but now i am trying to re-use this for another project but how to i flash this back to a stock form. as when plugged back in to pc its coming up with they freejoy and not able to get it to show for pro...
I'm looking at the STM32H7B0xB. I'm confused about what the actual maximum baud rate of the UART (in asynchronous mode) is. I'm getting three conflicting answers:Section 3.38 (the USART section of the datasheet) says: "These interfaces provide asynch...
Hello,I was using STM32 Blue Pill board and it was working fine until few hours ago. It suddenly stopped working. I was trying to make the built-in LED (At PC13) blink using Arduino IDE but it's not even blinking when i do Reset now. I've tried Flash...
I'm considering using a QSPI RAM to expand the RAM of an STM32H7 device (not FLASH).If possible, I'd like to use memory mapped mode. However, when I was doing research on this, I ran across a bunch of posts saying that memory mapped mode for QUAD-SPI...
Hi!I am developing a custom loader for a custom H7-board with a OSPI with a page size of 512 bytes (0x200). Naturally the programming via the Write() function needs to be optimized in programming whole pages aligned on boundaries and so on.When debug...
